Descriptive Report of the Invention Patent for TRANSMISSION AND RECEPTION OF SYNCHRONIZATION SIGNS FOR THE RADIO SYSTEM.
[001] This application claims the priority and benefit of US provisional patent application No. 62 / 501,716, filed on May 4, 2017, entitled SYNCHRONIZATION SIGNAL TRANSMISSION FOR RADIO SYSTEM, which is hereby incorporated in its entirety, by way of reference.
TECHNICAL FIELD
[002] The present invention relates to wireless communications and, in particular, methods and apparatus for requesting, transmitting and using synchronization signals in wireless communications. BACKGROUND OF THE INVENTION
[003] In wireless communication systems, a radio access network generally comprises one or more access nodes (such as a base station) that communicate over radio channels through a radio or air interface with multiple wireless terminals. In some technologies, such a wireless terminal is also called User Equipment (UE, User Equipment). A group known as Partnership Project 3 Generation (3GPP) PROPOSSE to define technical specifications and globally applicable technical reports for wireless communication systems, current and future. The Long Term Evolution 3GPP (LTE - Long Term Evolution) and LTE 3GPP Advanced (LTE-A from 3GPP LTE Advanced), are projects to enhance a previous standard of phones or mobile devices of the Universal Mobile Telecommunications System (UMTS, from Universal Mobile Telecommunications System) to address future requirements.
[004] Work began at the International Telecommunication Union (ITU) with the 3GPP responsible for development
Petition 870190110414, of 10/30/2019, p. 11/194
2/75 requirements and specifications for new radio 5G systems (NR, from New Radio), for example, fifth generation systems. Within the scope of 3GPP, a new study item (SID), the Study on New Radio Access Technology, or study on new radio access technology, was approved. The NR development agenda and study situations are summarized in document RP-161596, Revision of SI: Study on New Radio Access Technology, produced based on the 3GPP TSG RAN Meeting # 73, in New Orleans, held on 19 September 22, 2016. To meet the requirements of 5G technology, changes about the LTE 4G system were proposed for study, such as using the higher frequency spectrum (for example, 6 GHz, 40 GHz or even 100 GHz), numerology scalable (for example, spacing between different subcarriers (SCS), 3.75 KHz, 7.5 KHz, 15 KHz (current LTE), 30 KHz etc., up to possibly 480 KHz), beam-based initial access (a traditional cell may contain several due to the particular beam formation adopted).
[005] Pre-5G LTE systems can be treated as single beam systems. In addition, in such LTE systems, hierarchical synchronization signals, i.e., primary synchronization sequences (PSS) and secondary synchronization sequences (SSS) provide approximate time / frequency synchronizations, physical layer cell ID identification (PCI, from Physical Cell ID), identification of subframe timing, differentiation of type of frame structure (FDD or TDD) and identification of cyclic prefix overload (CP, from Cyclic Prefix). In addition, on pre-5G LTE systems, a physical broadcast channel (PBCH) provides additional information, such as the system frame number (SFN) and essential system information for a wireless terminal (UE) to obtain information to access the network. An initial access procedure
Petition 870190110414, of 10/30/2019, p. 11/20
3/75 for a pre-5G LTE system is illustrated in Figure 1.
[006] In the LTE system, three PSS strings provide cell ID identification (0 to 2); and SSS strings provide group identification of cell IDs (0 to 167). Therefore, in total, 168 * 3 = 504 PCI IDs are supported on the LTE system. At a RAN1 # 87 meeting, it was pointed out that the number of IDs provided by the PSS / SSS NR strings should be studied. See, for example, the Chairman's Notes of the 3GPP RAN1 meeting # 87. Additionally, one of the items agreed at the RAN1 # 86 meeting was the detection of the NR cell and its ID. See, for example, the notes of the President of the 3GPP RAN1 # 86 meeting.
[007] In the next generation new radio (NR) technology, a cell is expected to correspond to one or more transmission and reception points (TRPs, of Transmission and Reception Points). This means that multiple TRPs can share the same NR cell ID, or that each transmit and receive point (TRP) can have its own identifier. Additionally, the transmission of a TRP can be in the form of a single beam or multiple beams. Each of the bundles can also have its own identifier. Figure 2 shows an example of a simplified representation of a relationship between cell, transmission and reception point (TRP) and beam.
[008] It was agreed at the RAN1 # 86bis meeting, see, for example, the Notes of the President of the 3GPP RAN1 # 86 meeting that:
• PSS, SSS and / or PBCH (physical broadcast channel) can be transmitted within a synchronization signal block, or 'SS block' o Multiplexing of other signals is not prevented in an 'SS block' • One or multiple 'SS block (s)' that make up a
Petition 870190110414, of 10/30/2019, p. 11/214
4/75 burst of burst or 'burst of SS' • One or multiple 'burst of SS' make up a set of burst of burst signal, or 'set of burst of SS' o The number of burst of SS in a set of SS bursts is finite.
• From the point of view of the RAN1 specification, the NR air interface defines at least one SS burst set periodicity (note: the SS burst interval can be the same as the SS burst set interval in some cases, for example, single beam operation)
[009] Figure 3 is an exemplary NR SS block structure, according to meeting RAN1 # 86bis. In Figure 3, a series of bursts of synchronization signal represents a set of bursts of SS. Additional detailed examples are illustrated in the report R1 - 1610522, WF on the unified structure of DL sync signal, Intel Corporation, NTT DOCOMO, ZTE, ZTE Microelectronics, ETRI, InterDigital, of the meeting held in Lisbon, Portugal, from 10 to 14 October 2016. According to the report R1-1611268, Considerations on SS block design, ZTE, ZTE Microelectronics, Reno, Nevada, USA, from the meeting held from 14 to 18 of 2016, the SS block structure in Figure 3 can be as shown in Figure 4. Figure 4 shows that a sync signal block can be structured as a time division multiplex sync signal block, or as a frequency division multiplex sync signal block, or like a hybrid. Figure 4 further shows that a sync signal block can comprise, for example, sync signals (as the primary primary sync signal (PSS) and a secondary sync signal (SSS)), and a physical broadcast channel (PBCH) ), or otherwise, non-synchronized / non-PBCH information, such as
Petition 870190110414, of 10/30/2019, p. 11/22
5/75 reference, for example.
[0010] According to President's Notes 3GPP RAN1 # 87, it was further agreed that:
• At least for a case of multiple beams, at least the time index of the S block is indicated to the UE; and • From the UE perspective, the SS burst set transmission is periodic and that at least for initial cell selection, the UE may assume a standard SS burst set transmission period for a given carrier frequency. [0011] In pre-5G LTE, PSS / SSS and PBCH have different periodicities due to different detection performance requirements and different methods of eliminating channel distortion. For example, PBCH has channel encoding and repetition to combat channel distortion, while PSS / SSS does not. The multiplexing methods described in R1-1611268, Considerations on SS block design, ZTE, ZTE Microelectronics, Reno, USA, in November 2016, 14-18, 2016 and Figure 4 may not work directly, as it is possible that both PSS / SSS and PBCH are not included in that SS block.
[0012] As shown in Figure 3, one or multiple SS blocks make up an SS burst, and one or multiple SS bursts additionally comprise a set of SS bursts. The maximum integer L of SS blocks within a set of SS bursts can be specified. It is possible that, in different frequency bands, L could have different values, for example, for frequencies up to 3 GHz, L could be the value of the set of values [1, 2, 4]; for the frequency range from 3 GHz to 6 GHz, L could be the value of the set of values; for the frequency range from 6 GHz to 52.6 GHz, L could be [64],
[0013] Within a set of bursts SS, L can be referred to
Petition 870190110414, of 10/30/2019, p. 11/23
6/75 as corresponding to the number of SS blocks nominally transmitted. A nominal SS block is an SS block that can potentially be transmitted in the set of bursts of synchronization signaling block (SS) by a node. The nominal SS block indicates the possible location of the SS block time, for example, the position of the SS block in the time domain (Figure 3 shows that the SS blocks are arranged in positions in the time domain). The number and positions of the nominal SS blocks in a set of SS bursts can be predefined. Therefore, a wireless terminal that operates in different frequency bands must have knowledge of such nominal SS blocks, for example, such knowledge of the nominal SS blocks. The wireless terminal may be aware of the name blocks by such information that is stored in the memory of the wireless terminal, without network signaling, for example, pre-configured in the wireless terminal or configured by the network, for example, by signaling the network .
[0014] A node does not need to transmit all the nominal synchronization signaling (SS) blocks, but instead it can transmit only certain real synchronization signaling (SS) blocks, for example, the node can actually transmit only a subset of the nominal synchronization (SS) signal blocks. In addition, the position (or positions) of actual transmitted SS blocks can be provided to the UE for many purposes, including, but not limited to, assisting a UE in CONNECTED mode to receive DL data / control on unused and possibly SS blocks to help an UE in Idle mode to receive DL data / control in unused SS blocks.
[0015] What is needed, therefore, and examples of the objectives of the technology described here, are methods, apparatus and techniques for one or more among checking in advance a real number of blocks of
Petition 870190110414, of 10/30/2019, p. 11/24
7/75 sync signal transmitted by a node and correlating beams from a node to the received sync signal blocks.
SUMMARY
[0016] In some of these examples of aspects, the technology described here overcomes inefficiencies in telecommunications operations, for example, by providing a wireless terminal knowledge for which of the L integers of synchronization signal blocks of a set of bursts Synchronization signal block (SS) The node actually transmits synchronization signal blocks. Such pre-knowledge of actual sync signal block positions not only speeds up the processing of the set of sync signal block (SS) bursts, but also measurements that are intensively performed on a beam-by-beam basis. In another example of its aspects, the technology described here provides techniques for identifying the sync signal block indices and / or beam indices of an access node, so that the wireless terminal can correlate the energy measurements in reference signals for the real beams for the measurements to relate, and thus provide a better evaluation of the signal intensity to carry out the determinations of cell selection, cell reselection and / or cell transfer and the like.
[0017] An example of an aspect of the technology described here refers to user equipment and the method of operation of the same. The user equipment comprises receiving a set of circuits configured to receive bitmap information indicating time domain positions, within a measurement window, of the block (or blocks) of synchronization signal (SSB (s)) used for a intra and / or inter-frequency measurement, the (SSB (s) comprising at least one primary synchronization signal (PPS), one secondary synchronization signal (SSS), and one channel of

[0035] For use in the present invention, the term main network can refer to a device, group of devices or subsystem in a telecommunication network that provides services to users of the telecommunication network. Examples of services provided by a main network include aggregation, authentication, call switching, service invocation, gateways (communication ports) to other networks, etc.
[0036] For use in the present invention, the term wireless terminals can refer to any electronic device used to communicate voice and / or data through a telecommunication system, such as (but not limited to) a cellular network.

12/75 (eNB), a residential eNB (HeNB), or in 5G terminology, a next generation B node (gNB), or even a transmission and reception point (TRP), or some other similar terminology. Another non-limiting example of a base station is a connection point, or access point. A connection point can be an electronic device that provides the wireless terminal with access to a data network, such as (but not limited to) a local area network (LAN, Wide Area Network) (WAN, Wide Area Network), the Internet, etc. Although some examples of the systems and methods presented here can be described in relation to certain standards (for example, 3GPP versions 8, 9, 10, 11 etc.), the scope of the present disclosure should not be limited in this regard. At least some aspects of the systems and methods disclosed herein can be used in other types of wireless communication systems.
[0038] For use in the present invention, the term telecommunication system or communication system can refer to any network of devices used to transmit information. A non-limiting example of a telecommunication system is a cellular network or other wireless communication system.
[0039] For use in the present invention, the term cellular network can refer to a network distributed over several cells, with each cell being served by at least one fixed location transceiver, such as a base station. A cell can be any communication channel that is specified by standards or regulators to be used in the advanced international mobile telecommunications system (IMT-Advanced, from International Mobile Telecommunications-Advanced). The whole or a subset of the cell can be adopted by 3GPP as licensed bands (for example, frequency band) to be used for communication between

13/75 a base station, such as a B node, and an UE terminal. A cellular network that uses licensed frequency bands can include configured cells. The configured cells can include cells that the UE is aware of and in which it receives permission from a base station to transmit or receive information.
[0040] Figures 5A to 5E each show an example of the respective communication systems 20A to 20E, with the respective radio access nodes 22A to 22E, collectively called the radio access node 22, communicating via aerial or radio interface 24 (for example, Uu interface) with the respective wireless terminals 26A to 26E, collectively called wireless terminal 26. As mentioned above, radio access node 22 can be any suitable node for communication with wireless terminal 26, such as a base station node, or eNodeB (eNB) or gNodeB or gNB, for example. As used here, an access node or node should be considered to encompass all concepts related to a node, (for example) as a cell served by the node. Constituent elements and functionalities of exemplary communication systems 20A to 22E, which are similar in various exemplifying modes and modes, are designated by the same reference numbers. Node 22 comprises a node processor circuit (node processor 30) and a node transceiver circuit 32. Transceiver circuit 32 typically comprises a node transmitting circuit 34 and a node receiving circuit 36, which are also called a transmitter circuit. node and node receiver, respectively.
[0041] Wireless terminal 26 comprises a terminal processor 40 and a terminal transceiver circuit 42. The terminal transceiver circuit 42 typically comprises a terminal transmitting circuit 44 and a terminal receiving circuit 46, which
Petition 870190110414, of 10/30/2019, p. 11/314
14/75 are also called terminal transmitter 44 and terminal receiver 46, respectively. Wireless terminal 26 also typically comprises a user interface 48. Terminal user interface 48 can serve for user input and output operations, and can comprise (for example) a screen such as a touch screen that can display information to the user and receive information entered by the user. User interface 48 may also include other types of devices, such as a speaker, a microphone or a tactile feedback device, for example.
[0042] For both the radio access node 22A and the radio interface 24, the respective transceiver circuits 22 include antenna (s). The respective transmitting circuits 36 and 46 can comprise, for example, amplifier (s), a modulation circuit assembly and other conventional transmission equipment. The transmitter circuit 36 may comprise transmitters for multiple beams, for example, transmitter 34-1 for beam 0, including transmitter 34- (M-1) for beam M-1 (there being a total number of beam transmitters of integer potential M in this specific non-limiting example). The respective receiver circuits 34 and 44 can comprise, for example, amplifiers, demodulation circuits and other conventional receiver equipment.
[0043] In the general operating node, access node 22 and wireless terminal 26 communicate with each other via radio interface 24 using predefined information settings. As a non-limiting example, the radio access node 22 and the wireless terminal 26 can communicate via the radio interface 24 with the use of information boards can be configured to include multiple channels. In LTE (Long Term Evolution) technology, for
Petition 870190110414, of 10/30/2019, p. 11/32
For example, a frame, which can have both downlink and uplink portions, can comprise multiple subframes, each LTE subframe being in turn divided into two intervals. The framework can be conceptualized as a resource grid (a two-dimensional grid) comprising resource elements (RE, from Resource Elements). Each column in the two-dimensional grid represents a symbol (for example, an OFDM symbol on the downlink (DL) transmitted from the node to the wireless terminal; a SC-FDMA (Single-carrier Frequency Division Multiple Access) symbol. single carrier frequency division) in an uplink frame (UL) transmitted from the wireless terminal to the node). Each row of the grid represents a subcarrier. The structure of frames and subframes serves only as an example of a technique for formatting information that must be transmitted through a radio or air interface. It should be understood that the terms frame and subframe can be used interchangeably or can include or be executed by other information formatting units, and thus can include other terminology (such as blocks, or symbol, interval, mini 5G range, for example).
[0044] To support the transmission of information between radio access node 22A and wireless terminal 26 via radio interface 24, node processor 30 and terminal processor 40 of Figure 1 are shown comprising respective information handlers. For an exemplary implementation in which information is communicated through frames, the information handler for radio access node 22 is shown as a node frame / signal scheduler / handler 50, while the information handler for the wireless terminal 26 is shown as terminal board / signal handler 52.

16/75
[0045] The node processor 30 of the radio access node 22 comprises a sync signal generator 60. The sync signal generator 60 generates a set of bursts of sync signal block (SS) for the access node by radio 22, like the set of burst bursts of synchronization signaling (SS) shown in Figure 3. As mentioned above, a node transmitter circuit 34 of radio access node 22 comprises multiple beam transmitters, as an integer L of beam transmitters 34-1 to 34-M to transmit the maximum possible number of M beams (beams 0 - (M-1)) as shown in Figure 5A. In the specific exemplifying mode and mode of Figure 5A, there is a correspondence or relationship between the maximum number of M beams that can be transmitted by the radio access node 22A and the number N of nominal synchronization signal blocks that can be included in the set bursts of synchronization signaling block (SS) transmitted by the radio access node 22A. Preferably, but not necessarily always, such a relationship or correspondence is M = L, which means that each sync signal block in a set of sync signal block (SS) bursts is associated with and (if actually transmitted) is transmitted by its corresponding beam, as shown in Figure 6A. Other relationships may also exist, such as (for example) two or more burst signal blocks of the burst signal block (SS) if associated with a given beam or burst signal blocks of the burst burst block synchronization signaling (SS) are associated with two or more than two beams.
[0046] As mentioned above, an access node does not necessarily need to transmit on each synchronization signaling block (SS) of a set of signaling block bursts of
Petition 870190110414, of 10/30/2019, p. 11/34
17/75 synchronization (SS). For example, an access node can, for any one of several reasons, shut down one or more of its beam transmitters. Figure 6B shows an example of a non-limiting situation in which a radio access node comprises eight beam transmitters 34-0 to 34-7, and in which the set of bursts of synchronization signaling block (SS) consequently comprises eight nominal sync signaling (SS) blocks. At a particular point in the situation shown in Figure 6B, however, only three of the beam transmitters are activated or are actually transmitting, that is, transmitters for beams 0, 3, and 5. Consequently, for the time shown in Figure 6B the radio access node actually transmits only three synchronization signaling blocks (SS) in the set of block bursts in the synchronization signaling (SS) of Figure 6B, for example, synchronization signal blocks 0, 3, and 5. For For example, one or more synchronization signaling (SS) blocks may not be transmitted within the SS burst set. For example, a position (or positions) in which the SS block (or blocks) may or may not be transmitted within the SS burst set may be called a nominal SS block position (or positions). Here, the position (or positions) of the nominal SS block can be defined by the specification and known information between the gNB and the wireless terminal. In addition, the position (or positions) of the nominal SS block can be configured using the PBCH, the PDSCH, that is, the SIB and / or the system information message and / or the dedicated RRC signaling.
[0047] Wireless terminal 26A comprises a sync signal processor 62 that handles the burst set of sync signal block (SS) after the array is received by the receiver circuitry of terminal 46. Signal processor 62 can understand the frame / signal scheduler / handler
Petition 870190110414, of 10/30/2019, p. 11/35
18/75 of terminal 52, which in turn may comprise terminal processor 40. The synchronization signal processor 62 decodes the synchronization signaling blocks (SS) of the received synchronization signaling block (SS) burst set, and tries to obtain from each one an indication of the identity of the specific beam by which the synchronization signaling block (SS) was transmitted. For example, for the situation shown in Figure 6B, the sync signal processor 62 will attempt to determine, from the content of the respective sync signal blocks (SS) or otherwise, the beams that transmitted the sync signal blocks 0, 3 and 5. Keep in mind that the sync signal blocks may not be received in the exact order shown, so it is preferable, when possible, to receive some signature or other identification for the beam carrying each block synchronization signal received.
[0048] Wireless terminal 26A needs to know an identification of each beam associated with each sync signal block in the set of sync signal block (SS) bursts for reference signal measurement purposes, and finally for possible cell selection, cell reselection and / or cell transfer based on such measurements. Figure 5A shows that the wireless terminal 26A comprises reference signal measurement unit 64 (measurement unit 64), which detects the energy received in the reference signals that, in some exemplary implementations, can, by themselves or their equivalents , be included in the sync signal blocks, as explained below. Reference signal measurements are performed in relation to each beam, which is why it is important that the synchronization signal blocks received in a set of synchronization signal block (SS) bursts are distinguishable on a beam basis. THE
Petition 870190110414, of 10/30/2019, p. 36/114
19/75 measurement unit 64 performs measurements for each beam over a measurement time interval and calculates averages or otherwise quantifies such measurements for each beam through the measurement time window. The measurement unit 64 can also, in a filtering operation, quantify, score or classify the strength or transmission quality of a given node based on measurements performed from one or more beams of the node. For example, the measurement unit 64 can average the results of several bundles of the node, for example, all bundles of the node, a predetermined number of bundles of the node, a number of better bundles of the node, etc. Measurement unit 64 is generally performing beam measurements that relate to multiple cells / nodes. Generally, the wireless terminal 26A is intended to monitor or measure not only the strength of a support node through which the wireless terminal 26A communicates primarily with the radio access network, but also several other neighboring nodes that can be of interest for possible transfer if the strength of the server node decreases sufficiently.
[0049] Reference signals are typically included in the synchronization signal blocks. For example, in addition to its synchronization function, the secondary synchronization signal (SSS) serves as a reference signal for measurements to a wireless terminal in idle mode. For essentially all RRC modes, the SSS serves, at least to some degree, as a reference signal, and being in the sync signal block means that the sync signal block includes a reference signal. It is also possible that a channel status information reference signal (CSI-RI) may be included in the synchronization signal block and, if included, may serve as alternative or additional reference signal symbols for the measurement. Alternatively, the CSI-RI can be (1)

20/75 included in the SS burst concept, for example, an SS burst can be formed by an SS block with some signal and / or data and / or additional signaling, such as CSI-RI, PDSCH, PDCCH, or (2) included somewhere with some predefined relative SS block positions, but not counted as part of an SS block, nor part of an SS burst, nor part of an SS burst set.
[0050] The measurements collected by the measurement unit 64 are transmitted or reported to a cell selection / reselection / transfer functionality. Such functionality can be in the wireless terminal itself, as in the case shown in Figure 5A, or in the radio access node 22A. Thus, Figure 5A additionally shows the terminal processor 40 of the wireless terminal 26A as comprising the cell selection / reselection / transfer (HO) unit 66. The cell selection / reselection / transfer unit 66 serves to compare the measurements filtered from multiple cells, and to generate a communication or request to the radio access network in the event that cell selection / reselection / transfer unit 66 believes that a change in the relative signal strength of competing nodes justifies a transfer or transfer to a neighboring node.
[0051] In view of the many operations that include the detection of the synchronization signaling blocks (SS) and the measurements carried out on a beam base, it would be beneficial that a terminal that receives a set of bursts of synchronization signaling block (SS) to know in advance which of the integers of sync signal blocks in a set of sync signal block (SS) bursts the node actually transmits sync signal blocks. Specifically, the wireless terminal can use the position (or positions) of the actual transmitted SS block (or blocks), for example, the actual transmitted block (or blocks) SS time index
Petition 870190110414, of 10/30/2019, p. 11/38
21/75 to detect the SS block (or blocks) within the SS burst set. In addition, the wireless terminal can use the position (or positions) of the real transmitted SS block (or blocks) within the SS burst set for measurement, for example, neighbor cell measurement. The maximum integer L of SS blocks within an SS burst set can be the SS block number within the SS burst set. Such foreknowledge of actual sync signal block positions can not only streamline the processing of the set of sync signal block (SS) bursts, but also measurements that are intensively performed on a beam-by-beam basis. Consequently, Figure 5A shows the radio access node 22, and the node processor 30, in particular, as comprising a beam usage information generator 70 that advantageously provides the wireless terminal with certain beam usage information. Figure 5A shows that the beam information generator 70 generates the beam usage information (BUI), also known as first information, which is transmitted through the radio interface to the wireless terminal 26A. The beam usage information is received by the receiving circuitry of the terminal 46, and processed by the beam information handler 72 of the frame / scheduler / terminal handler 52, for use by the sync signal processor 62 in decoding and efficient processing of the set of bursts of synchronization signaling block (SS) received from the node.
[0052] Figure 7 shows basic representative actions or exemplary steps performed by the radio access node 22A of Figure 5A. Action 7-1 comprises the beam usage information generator 70 which generates beam usage information. In an exemplifying mode and mode in which the beam usage information is the actual number of beam transmitters, for example, the actual number of

22/75 sync signal blocks that are transmitted in a set of sync signal block (SS) bursts, radio access node 22A knows which of the many potential beam transmitters L are actually connected and, consequently, you can configure the beam usage information to be that number of activated beam transmitters. In an exemplifying mode and mode in which the beam usage information comprises beam identification information, such as action 7-1 the beam usage information generator 70 can prepare the set of bursts of synchronization signaling block ( SS) so that the sync signal block indices or beam indices are included in the sync signal blocks of the sync signal block (SS) burst set. Action 7-2 comprises radio access node 22A which transmits beam usage information through a radio interface 24. Action 7-3 comprises synchronization signal generator 60 which generates a set of block bursts synchronization signaling (SS) to be transmitted by the node. Action 7B-4 comprises radio access node 22A which periodically transmits the set of bursts of synchronization signaling block (SS) through the radio interface. If the contents of the set of burst bursts of synchronization signaling (SS) change, action 7-3 is performed for each such change, followed by action 7-4. Action 7-1 is performed whenever the content of the beam usage information changes, each such change being followed by the performance of the other actions in Figure 7.
[0053] Figure 8 shows basic representative actions or exemplary steps performed by wireless terminal 26A of Figure 5A. Action 8-1 comprises beam terminal 26A that receives beam usage information from the access node. Action 8-2 comprises the wireless terminal 26A which periodically receives a set of
Petition 870190110414, of 10/30/2019, p. 11/40
23/75 bursts of synchronization signaling block (SS) transmitted by the node. Action 8-3 comprises using the beam usage information to decode the set of bursts of synchronization signaling block (SS). The optional action 8-4 comprises the wireless terminal 26A which performs a measurement based on the sync signal blocks actually received from the sync signal block (SS) burst set. After action 8-4 measurements are taken, the measurement results can be reported to the radio access network in conjunction with a cell selection / reselection operation.
[0054] In at least some of the modality and exemplifying modes, such as those discussed in section A below, the beam usage information generated by the beam usage information generator 70 specifies which of the L integers of signal blocks synchronization of a set of bursts of synchronization signal block (SS) the node actually transmits synchronization signal blocks. That is, the beam usage information can be used to indicate that the nominal SS block (or blocks) number (or blocks), and / or the SS block (or blocks) number (or blocks), and / or the nominal transmitted block (or blocks) position (or blocks) and / or the position (or positions) of the actual transmitted block (or blocks) within the SS burst set. Here, the number (or numbers) and / or position (or positions) of the actual transmitted SS block (or blocks) can be identified within the number (or numbers) and / or the position (or positions) of the block (or blocks) ) Nominal SS. In another embodiment and exemplifying modes, such as those discussed and presented in section B below, the beam usage information generated by the beam usage information generator 70 comprises beam identification information.
A. Conventions for specifying the use of real beam
Petition 870190110414, of 10/30/2019, p. 41/114
24/75
[0055] There are several different conventions for expressing and transmitting beam usage information in situations where beam usage information comprises an indication of which sync signal blocks, the integer L of the nominal sync signal blocks of a set of bursts of synchronization signaling block (SS), are actually transmitted by the node. In these exemplifying modes and modes, the node processor 30 can generate the beam usage information to be transmitted separately via the radio interface from the set of bursts of synchronization signaling block (SS), for example, the information of beam usage cannot be included in the sync signal blocks of the burst set of sync signal block (SS). By providing an indication (for example, the first information) of which of the sync signal blocks of the burst signal block (SS) burst are actually transmitted, the beam usage information indicates the actual contents of the array of bursts of synchronization signaling block (SS). For example, the indication of which position (or positions) of the nominal S block (or blocks) is used (or are used) for the actual SS block (or blocks) transmission.
[0056] Thus, for a given carrier frequency, it is assumed that the maximum number of SS blocks, for example, the position number (or positions) of the nominal SS block (s), within an SS burst set whether preset, or preconfigured as L, the following designs or conventions can be used to inform the wireless terminal of the actually transmitted block (or block) SS positions. The beam usage information description conventions described herein can be transmitted by radio access node 22 to wireless terminal 26 using any one or more or physical broadcast channel (PBCH) combinations,
Petition 870190110414, of 10/30/2019, p. 42/114
25/75 broadcast, or as system information, as minimum remaining system information or any other system information messages.
A.1 Bitmap convention
[0057] In an exemplifying mode and mode generally represented by Figure 5B, the actual transmitted sync signaling block (SS) positions are reported to the wireless terminal as bitmap information. In this alternative design, the L bits are needed to carry the information in the format of [bo, bi, ..., bi_-i)], where b _n and {0,1}, 0 <n <L - 1. Counting can start from b1 with 1 <n <L. In the example and mode of Figure 5B, the beam usage information generator 70 takes the form of the beam usage information bitmap generator 70B, and the wireless terminal 26B is provided with a bitmap manipulator of beam usage information 72B.
[0058] As an example, it is assumed that, in a given frequency band, it is possible for a maximum of eight synchronization signaling blocks (SS) to be transmitted within a set of synchronization signaling block bursts (SS) . If all 8 SS blocks are used for synchronization and actually transmitted, then the bitmap information [0,0,0,0,0,0,0,0] or [1,1,1,1,1,1,1, 1.1] are provided by wireless terminal 26B to wireless terminal 26B. Either 0 or 1 can indicate the actual transmitted SS block. If this example is consistent with the situation shown in Figure 6B, in which three blocks of synchronization signal that carry synchronization information must actually be transmitted (for example, blocks 0, 3, and 5 that are respectively in the first, fourth and sixth SS block positions of the SS burst set), then the bitmap information [1,1,0,1,0,1,1,0] or [0,0,1,0,1,0,0, 1] are provided by wireless terminal 26B for the
Petition 870190110414, of 10/30/2019, p. 43/114
26/75 wireless terminal 26B, depending on whether 0 or 1 indicates the actual transmitted SS block.
[0059] In the example above, the first and last possible SS block transmission positions within a set of SS bursts correspond to the left and right bits of the bitmap vector respectively. The order can be naturally reversed, so as to make the first and last SS block positions possible within a set of SS bursts that correspond to the bits to the right and left of the bitmap vector, respectively.
[0060] In the bitmap convention, node processor 30 is configured to generate beam usage information as a bitmap that specifies which of the integer sync signal blocks L of a set of sync signal block bursts (SS) the node actually transmits blocks of synchronization signal. Terminal processor 40 is configured to decode beam usage information as a bitmap that specifies which of the L integer sync signal blocks of a set of sync signal block (SS) bursts the node actually transmits sync signal blocks.
[0061] As described below, there are at least two different ways to carry the bitmap of beam usage information.
A.1.1 Bitmap convention: direct bitmap transmission
[0062] The bitmap information to express the beam usage information can be transmitted by the information bits in a sequence or a channel directly. That is, the node processor circuit 30 and the beam usage information bitmap generator 70B, in particular, is configured to generate the beam usage information as a bitmap as a bit sequence or channel. After the 26B wireless terminal correctly detects the related sequence or ο 26B can correctly decode the related channel
Petition 870190110414, of 10/30/2019, p. 44/114
27/75 swimming, the wireless terminal 26B knows the beam usage information directly. The signaling overhead associated with the direct bitmap transmission technique is directly related to the value of L.
A. 1.2 Bitmap convention: bitmap transmission by scrambling
[0063] Bitmap information to express beam usage information can be used, instead, as a scramble sequence to encode other bits. The bitmap encoding can be in any scrambled mode, for example, XOR bit operation between the bitmap sequence and other bits, of a sequence, or of a channel. For use in the present invention, other bits could be information bits, or parity bits, for example, CRC bits, or both, that are transmitted on any channel (for example, PBCH, or channel used for dedicated signaling or channel used for system information). The length of the scrambling information must be the same length as the scrambling bits. Thus, for this technique, the node 30 processor circuit and the beam usage information generator 70B, in particular, as augmented by the scrambler 74, are configured to generate the beam usage information as downlink information that is scrambled or encoded by the bitmap. In this technique, no dedicated bit positions are required for bitmap information; however, it is at the expense of complexity for blindly decoding bit information by attempting different candidate bitmap strings to detect the right candidate.
A.2 Index convention
[0064] In another exemplifying mode and mode, beam usage information in the form of position information
Petition 870190110414, of 10/30/2019, p. 45/114
28/75 of actual transmitted SS blocks are provided by the radio access node to the wireless terminal as an index. According to some mappings between the index and the pattern of actually transmitted positions, the wireless terminal knows where the actual transmitted SS block positions are located. The mapping relationship can be predefined, for example, by an industry standard or specification, or preconfigured, for example, through the use of broadcast information, for the wireless terminal. For example, the mapping relationship can be stored in the memory of the wireless terminal, so that, once the wireless terminal has obtained the index information, the wireless terminal reaches the actual SS block positions transmitted with the relationship known mapping.
[0065] Figure 5C shows the generation of beam usage information according to the index convention, and particularly that node processor 30 comprises beam usage index information generator 70C, which includes a memory unit 76 that stores a mapping of index values to respective block patterns to actually be transmitted. In this way, a processor circuit 30 of radio access node 22C and the beam usage information generator 70C, in particular, are configured to generate the beam usage information as an index of multiple possible index values, being that each of the multiple possible index values corresponds to a single one among several actual synchronous signal block transmission patterns. Figure 5C further shows that the terminal processor 40 of the wireless terminal 26C, and the frame / signal scheduler / terminal manipulator 52, in particular, comprises the beam usage index manipulator 72C, which has access to a mapping of comparable memory 78 of index values to the actually transmitted block patterns.
Petition 870190110414, of 10/30/2019, p. 46/114
29/75
[0066] The mapping relationship can also be signaled by the radio access node 22C to wireless terminal 26C through broadcast signaling, or dedicated RRC signaling. Such signaling can be either to provide the 26C wireless terminal with the mapping interface, for example, download by initial download, or to update the existing mapping interface on the 26C wireless terminal. The terminal processor 40 of the 26C wireless terminal is configured to decode the beam usage information as an index of multiple possible index values, each of the multiple possible index values corresponding to a single of several transmission patterns. real sync signal block.
[0067] The index can be carried in any non-binary format, for example, octal, decimal or hexadecimal. Therefore, it can only be carried by a bit in a channel, instead of being carried by a type of sequence. In other words, an index is transmitted as a channel bit through the radio interface.
[0068] As an example of index transmission as a channel bit, consider an example in decimal format where, in a given frequency band, a maximum of four SS blocks may be transmitted within a set of SS bursts . If all four SS blocks are used for synchronization and actually transmitted, then 0 or 15 (can also count as 1 or 16), is provided for wireless terminal 26C, if the lowest value 0, or the highest value 1, indicate the case that all SS blocks with SS burst set are actually transmitted. When the wireless terminal 26C obtains the information, for example, 0 or 15, the wireless terminal 26C knows that it can be mapped to the transmitted pattern in which all SS blocks are actually transmitted. If within the SS burst, in a practical case, two SS blocks that carry synchronization information must actually be transmitted, the
Petition 870190110414, of 10/30/2019, p. 47/114
30/75 which are in the first and third positions of the burst block SS block, so when the 26C wireless terminal gets the index information (5 or 10, if the lowest value 0, or the highest value 1, indicate the case where all SS blocks with the SS burst set are actually transmitted), according to the mapping relationship shown in Table 1, wireless terminal 26C knows which nominal SS block positions have actual SS block transmissions. Table 1 shows a mapping between the SS block TX pattern index and the real SS block TX pattern.
Table 1: exemplificative transmission mapping index
index (for example, decimal format) Actual transmitted standard 0 [0.0,0.0] 1 [0.0,0.1] 2 [0.0,1.0] 3 [0.0.1.1] 4 [0.1,0.0] 5 [0,1,0,1] 6 [0,1,1,0] 7 [0,1,1,1] 8 [1,0,0,0] 9 [1,0,0,1] 10 [1,0,1,0] 11 [1,0,1,1] 12 [1,1,0,0] 13 [1,1,0,1] 14 [1,1,1,0] 15 [1,1,1,1]
[0069] In the example in Table 1 above, the first and last possible SS block transmission positions within a set of SS bursts correspond to the left and right bits of the bitmap vector, respectively. The order can be naturally reversed, so as to make the first and last nominal SS block positions within a set of SS bursts corresponding to the bits to the right and left of the bitmap vector, respectively.
[0070] The number of bits of information in the index can be changed by the value of L, which is diffused. In addition, an interpretation of a
Petition 870190110414, of 10/30/2019, p. 48/114
31/75 a certain index value can be changed by the L value that is spread. The actual transmitted pattern can be as a function of the index and L, for example, assuming the pattern is T and the index is I, then T = f (l, L). Therefore, when I and L are determined, the pattern is determined. For example, in Table 1 L = 4, so if L is updated to 2, then even in the original and updated case, the wireless terminal receives the same I, for example, 2. In the latter case, it can indicate the transmitted pattern real [1.0], and that there could be a simple table for L = 2: 0 -> [0.0], 1 -> [0.1], 2 -> [l, 0], 3 -> [ 1.1],
A. 3 Conventional usage techniques
[0071] Multiple carrier frequency bands can be used in a radio access network, and in fact, multiple carrier frequency bands can be used for transmission from a given access node. The beam usage description conventions described above (for example, BITMAPS CONVENTION: DIRECT BITMAP TRANSMISSION, BITMAP CONVENTION: SHUFFLE BITMAP TRANSMISSION and INDEX CONVENTION) can be used solely or in combination in various contexts of bands of index frequency of multiple carriers. Non-limiting examples of conventional employment techniques are described below:
A. 3.1 Uniform convention use technique
[0072] In an exemplifying mode and mode, the transmitter circuitry 34 is configured to transmit the burst sets of synchronization signaling block (SS) across multiple carrier bands, and the node processor generates the usage information beam according to the same convention for describing beam usage information for each of the multiple carrier bands. For example, Figure 9A shows an example where the beam usage information generator 70 for the node
Petition 870190110414, of 10/30/2019, p. 11/4
32/75 radio access 22 generates beam usage information for each of the three carrier frequency bands according to the same beam usage information description convention (for example, bitmap). Alternatively, the beam usage information generator 70 could have generated the beam usage information for all three carrier frequency bands using another convention describing uniform beam usage information, such as the convention index. The receiving circuit of wireless terminal 26 is configured to receive a set of bursts of synchronization signaling block (SS) in multiple carrier bands. Terminal processor 40 is configured to decode beam usage information according to the same description convention for each of the multiple carrier bands.
A. 3.2 Techniques for using the non-uniform convention
[0073] In another exemplary mode and mode in which the transmitter circuitry 34 is configured to transmit sets of bursts of synchronization signaling block (SS) in multiple carrier bands, the node processor generates the usage information differently for at least two different carrier frequency bands. For example, Figure 9B shows an example where the beam usage information generator 70 from radio access node 22 generates beam usage information for a first and second of three carrier frequency bands according to a convention bitmap description, but generates the beam usage information for a third carrier frequency band according to another usage information description convention (for example, index). Thus, the beam usage information generator 70 in Figure 9B generates the beam usage information according to a first convention for a first carrier band (for example,
Petition 870190110414, of 10/30/2019, p. 50/114
33/75 carrier frequency 1 or carrier frequency band 2) and generates the beam usage information according to a second description convention for a second carrier band (for example, carrier frequency band 3). In this way, an alternative design is used per carrier frequency band; different carrier frequency bands use different alternative designs, for example, beam usage information is configured differently for different frequency bands. Terminal processor 40 is configured to decode beam usage information according to a first convention for a first carrier band, and to decode beam usage information according to a second description convention for a second carrier band . It was mentioned above that, in different frequency bands, the maximum integer L of SS blocks may have different values. Examples were given, for example, of a frequency range of up to 3 GHz, where L could be the value of the set of values [1, 2, 4], of a frequency range of 3 GHz to 6 GHz, where L could be the value from the set of values; and, a frequency range from 6 GHz to 52.6 GHz, where L could be [64], Thus, in a convention in which the beam usage information is expressed in a bitmap convention, for example, the bitmap information is expressed as a bit string, different lengths of the string can be defined for different frequency bands. In other words, the length of the bit string may depend on the specific frequency band.
[0074] In another exemplary mode and mode in which the transmitter circuitry 34 is configured for sets of burst bursts of synchronization signaling (SS) in multiple carrier bands, more than one alternative design can be used
Petition 870190110414, of 10/30/2019, p. 51/114
34/75 per carrier frequency band, and different carrier frequency bands use different alternative designs. As an implementation example, Figure 9C shows a beam usage information generator 70 for radio access node 22 that generates the beam usage information according to different conventions for describing beam usage information for a first carrier frequency band subset 1 and for a second carrier frequency band subset 1. That is, different subsets of the same carrier frequency band are provided with beam usage information according to different information description conventions beam usage. In the specific example of Figure 9C, the first carrier frequency band subset 1 receives the beam usage information as a bitmap, while the second carrier frequency subset 1 receives the beam band usage information as an index. That is, the beam usage information generator 70 is configured to generate the beam usage information using a first description convention for a first subset of frequencies in the same carrier frequency band and using a second description convention for a second subset of frequencies in the same carrier frequency band. Terminal processor 40 is configured to decode beam usage information using a first description convention for a first subset of frequencies in the same carrier frequency band and using a second description convention for a second subset frequencies in the same carrier frequency band.
[0075] As another exemplary implementation, Figure 9D shows a beam usage information generator 70 for radio access node 22 that generates beam usage information with the
Petition 870190110414, of 10/30/2019, p. 11/114
35/75 use of a first description convention for a first duration of the same carrier frequency band and with the use of a second description convention for a second duration of the same carrier frequency band. In particular, for a period of time 1, the beam usage information generator 70 expresses the beam usage information using the bitmap description convention for carrier frequency band 1, but for a moment later, for example, the duration of time 2, the beam usage information generator 70 expresses the beam usage information using the index description convention for carrier frequency band 1. The beam usage 70 may wish to use different conventions for describing beam usage information at different times in view of the various changed circumstances such as, for example, the radio access node using a different number of beams. Different beam usage information description conventions can have different advantages during different circumstances, making a change in beam usage information description convention advantageous at certain times. Terminal processor 40 is configured to decode beam usage information using a first description convention for a first duration of the same carrier frequency band and using a second description convention for a second duration time of the same carrier frequency band.
B. Conventions for identifying used bundles
[0076] In the exemplary mode and modes discussed above, the beam usage information generated by the beam usage information generator 70 specifies which of the L integers of synchronization signal blocks in a set of block bursts
Petition 870190110414, of 10/30/2019, p. 53/114
36/75 synchronization signaling (SS) the node actually transmits synchronization signal blocks. In the exemplary mode and modes discussed below, the beam usage information generated by the beam usage information generator 70 comprises beam identification information. That is, node processor 30 generates beam usage information to indicate beam identification information for one or more multiple beams associated with the sync signal blocks of a set of sync signal block (SS) bursts. .
[0077] As explained above, it is important that the wireless terminal 26 distinguishes between the beams through which the synchronization signal blocks of the set of synchronization signal block (SS) bursts are received. The distinction between the beams is necessary so that, for example, the measurements made by the wireless terminal 26 on the received signals are properly correlated with the beams and, therefore, so that an appropriate assessment can be made if the wireless terminal 26 should continue operate under the auspices of the server node, or transfer to another node offering better signal quality.
[0078] The distinction between beams from a node was not an issue in pre-5G radio communications systems. In fact, for pre-5G LTE systems, after detecting synchronization signals, during the initial access case, for example, the case of an initial cell selection of the wireless terminal in idle mode, when the wireless terminal does not is parking or connected to a cell, the wireless terminal decodes PBCH to obtain critical system information. On the other hand, during the identification of neighboring cells, for example, the case of the cell cell reselection and / or transfer, and measurement cases, for example, of the neighboring cell, the wireless terminal does not need to decode PBCH, but in instead, the wireless terminal does
Petition 870190110414, of 10/30/2019, p. 54/114
37/75 quality level measurements based on reference signals, RSRP / RSRQ, from the neighboring cell and then report the measurements to the serving cell to trigger possible cell transfer and / or reselection procedures.
[0079] In a new radio communication system, for example, a post-4G radio communication system, the synchronization signal block includes symbols for NR-PSS and NR-SSS, as well as a symbol (or symbols) for PBCH in activated cells, and possible CSI-RS symbols (channel status information reference signal), as illustrated by way of example in Figure 4. Additionally, if the requirements for mobility and transfer can be met, the PBCH that is carried in the synchronization signal block could be used to carry the time index indication, thus indicating the time position of the SS block within an SS burst or within a set of SS bursts. Here, the time index (eg position, time index indication) of the SS block (or blocks) indicated by the use of PBCH can be based on the nominal SS block position. For example, the time index of the SS block (or blocks) indicated by the use of PBCH can be counted (for example, identified by) in the nominal SS block position. In addition, the SS block (or blocks) time index indicated by the use of PBCH can be based on the actual transmitted SS block position. For example, the time index of the SS block (or blocks) indicated by the use of PBCH can be counted (for example, identified by) in the actual transmitted SS block position. Since the SS block carries synchronization information for each beam, the time index indication can also be used to indicate the beam index and thus address the concern discussed above that the wireless terminal is able to identify the associated beam. to the sync signal block for which the signal strength is measured.
Petition 870190110414, of 10/30/2019, p. 55/114
38/75
[0080] However, even for post4G communications systems it is not yet decided (for example, not yet standardized) whether the SS block from a disabled cell needs to carry symbols to PBCH. Therefore, it is not yet known whether the SS block needs to carry PBCH in each cell or not. In addition, even if each SS block carried the PBCH, and the PBCH included an index, the presence of the PBCH is not necessarily verified in all circumstances and in all generations of networks. For example, as explained above for LTE inherited during cell transfer or selection / reselection / transfer, wireless terminal 26 is not traditionally required to receive / decode system information from a neighboring cell when performing neighboring cell measurements. Therefore, even if the PBCH advantageously carries a beam index indication, it can be difficult for the wireless terminal to obtain the index information.
[0081] When measuring neighboring cells, the wireless terminal needs to measure some metrics, for example, signal strength or signal quality, from a reference signal to a neighboring node. In the new radio system, the wireless terminal can measure the signal strength or signal quality of a reference signal from each SS block for the purposes of transfer or selection / reselection / cell transfer, as generically described above. In a synchronization signal block, the reference signal (RS) could be either CSIRS or NR-XSS (for example, NR-SSS) or both. Such measurement should not normally be a one-shot reference (RS) signal capture procedure, but instead, there should be some measurement window with multiple shot RS captures in order to obtain a reliable measurement result. So at least in the process of measuring the next cell of a new radio (for example, post-4G) the wireless terminal needs to be configured with the information
Petition 870190110414, of 10/30/2019, p. 56/114
39/75 index of each SS block, since (as explained previously) the reference signal is based on beam and the filtering must be based on beam. Otherwise, (that is, if the index information for each SS block is not configured), (multiple beam operation, multiple SS blocks are detected within the SS burst set) if beam based, when the terminal wirelessly captures (for example, detects) 1 SS block and obtains the reference signal from it, it has no idea which reference signals from other SS blocks already captured should be associated with that reference signal for filtering.
[0082] Thus, in view of not being sure whether the new radio systems will require PBCH verification (for example, for index) in all applicable situations, and additionally in view of the need for compatibility with previous versions with the legacy LTE, the technology described here proposes several techniques for a radio access node to provide, and a wireless terminal to determine, the index of a beam that carries a block of synchronization signal to be processed, for example, for measurement of signal.
[0083] Therefore, for measurement of neighboring cell, so that the wireless terminal knows the information of SS block index / time index / beam index information and, in this way, performs the measurement filtering, the technology described here provides the alternative designs represented generically in Figure 5D. Figure 5D shows radio access node 22D as comprising used beam identification generator 70D, and wireless terminal 26D as comprising beam index manipulator 72D. In some exemplary modalities and modes, the 22D radio access node generates beam usage information to determine which of the multiple beams the processor circuitry generates a synchronization signal (SS) block on, and the wireless terminal 26E

40/75 decodes the beam usage information to determine for which of the multiple beams the processor circuitry generates a synchronization signaling block (SS).
B.1 Identification of used beams: PBCH decoding
[0084] In an exemplifying mode and mode, the radio access node 22D, and the used beam identification information generator 70D in particular, is configured to generate the beam usage information to understand a block index. synchronization signal carried on a physical broadcast channel of the synchronization signal blocks transmitted from the node. For the measurement of neighboring cells, after the detection of PSS / SSS, the wireless terminal 26 also always decodes the PBCH, regardless of whether the SS block index information is explicitly or implicitly carried by PBCH or not, in order to try obtain the SS block index associated with the PSS / SSS. After that, the wireless terminal can start measuring the quality of the reference signal. The 22D radio access node generates the beam usage information as a sync signal block index carried on a physical broadcast channel of the sync signal blocks transmitted from the node, and the 26D wireless terminal decodes the beam usage information as a sync signal block index carried on a physical broadcast channel of the sync signal blocks transmitted from the node.
B.2 Identification of bundles used: index scrambling system information
[0085] In an exemplifying mode and mode, the used 70D beam identification information generator is configured for symbol level shuffling of the transmitted system information using an SS block index that corresponds to a specific beam. Non-limiting actions or steps

41/75 representative examples performed by the radio access node 22D of Figure 5D according to the modality and mode of index scrambling examples are shown in Figure 10, showing both the BCH transport channel processing and the PBCH physical channel processing .
[0086] Action 10-1 comprises the radio access node 22D that receives information / data from the broadcast channel (for example, ao, ai, ... 3a-i). Action 10-2 involves performing a cyclic redundancy check operation (CRC attachment) on the received broadcast channel data (according to, for example, 3GPP 36.212 sections 5.3.1 / 5.3.1.1) and generating attached CRC data (e.g., Co, Ci, ... ck-i). Action 10-3 comprises performing a channel encoding operation on the attached CRC data (according to, for example, 3GPP 36.212 sections 5.3.1 / 5.3.1.2) and generating encoded data (for example, d ^, .. . dfLf). Action 10-4 comprises performing a fee matching operation (according to, for example, 3GPP 36.212 sections 5.3.1 / 5.3.1.3) on the encoded data, obtaining corresponding fee encoded data (for example, eo, ei, ... esi). Action 10-5 comprises performing a sequence shuffling operation (according to, for example, 3GPP 36.212 section 6.6.1) on the corresponding rate encoded data, to obtain modulated data (for example, bb ® ... b J ^ -i) · 10-6 ^the action comprises performing a modulating operation (according to, for example, 3GPP section 36.212 6.6.2) in the scrambled data to obtain modulated data (e.g., the, di, ... , dsymb-1). Action 10-7 involves performing symbol level shuffling of the modulated data (as described below) to obtain scrambled symbols. Action 10-8 involves performing a layer mapping / precoding operation (according to, for example, 3GPP 36.212 section 6.6.3) on the scrambled symbols to obtain
Petition 870190110414, of 10/30/2019, p. 59/114
42/75 layer mapped / pre-coded symbols. Action 10-9 comprises performing a feature element mapping operation (according to, for example, 3GPP 36.212 section 6.6.4) on the mapped / precoded layer symbols to obtain a feature element.
[0087] In the alternative design that uses symbol level scrambling of the system information transmitted using an SS block index corresponding to a specific beam, different from for action 10-7, the 22D radio access node uses similar procedures like LTE. However, in action 10-7 after the modulation action 10-6, the L Iog2 symbols carried by PBCH are scrambled with the SS block index, where the symbols are in some predefined positions, for example, the first L Iog2 symbol , or the last L Iog2 symbol, or some specific pattern of L Iog2 symbols. For action 10-7, the scrambling procedures are based on a modulated symbol, so there is BPSK conversion in the original bit stream that indicates the SS block index, for example, 0 -> +1 and 1 -> - 1 ; or 0 -> -1 and 1 -> + 1.0 shuffling of action 10-7 is performed by multiplying the BPSK sequence that indicates the SS block index with the modulated symbols of the corresponding positions.
[0088] As an example, in a high frequency band, a large number of, for example, 64 SS blocks, could be transported in a set of SS bursts. In such a case, a 6-bit string indicating the SS block index is used for scrambling.
[0089] During the measurement of neighbor cell reference signal quality, after the detection of PSS / SSS, the 26D wireless terminal also detects the SS block index by blindly detecting the scrambled sequence that indicates the SS block index . This detection
Petition 870190110414, of 10/30/2019, p. 60/114
43/75 tion is similar to the detection of PSS or SSS sequences, through coherent or non-coherent detection, for example, for coherent detection, the highest detected energy is the candidate sequence on the right that carries the SS block index. This alternative that uses symbol-level scrambling of the system information transmitted using an SS block index works well when L has a small value; when L is large, the complexity of blind detection increases.
[0090] Thus, in an exemplifying mode and mode, the 22D radio access node generates the beam usage information as a level shuffle symbol of system information transmitted from the node by the specific beam, and the terminal without 26D wire decodes the beam usage information as symbol level unscrambling system information transmitted from the node by the specific beam.
B.3 Identification of bundles used: Inter-node signaling
[0091] As mentioned above, if the PBCH carries the SS block index, whether implicitly or explicitly, the wireless terminal during initial access, in any case, does not need to decode the PBCH, so there is no problem for the wireless terminal get the SS block index information. A problem arises, however, during cell reselection, for example, idle mode and idle mode, and transfer of UE, for example, connected UE mode. In an exemplifying mode and mode, the wireless terminal follows the pre-5G LTE principles without decoding the PBCH in neighboring cell measurements to obtain SS block index information, and instead obtains the usage information from neighbor cell beam from the current wireless terminal server cell, through broadcast signaling or dedicated RRC signaling, or both.
Petition 870190110414, of 10/30/2019, p. 61/114
44/75
[0092] In this exemplary mode and mode, the wireless terminal obtains the actual SS block transmission position information, which is discussed in section A above, by signaling its server node. The information can be in the form of any or any combination designed in section A. Therefore, neighboring cells that are configured for the wireless terminal for measurement must have such information exchanged between eNB / gNB and, finally, signaled to the terminal without cord in the service cell of the wireless terminal. Since the intra-frequency neighbor cell measurements and the inter-frequency neighbor cell measurements are for different cell types, the serving cell uses different signaling to inform the UE about the information. Thus, in order to obtain the beam usage information in the exemplary mode and mode of Figure 5E, the wireless terminal does not need to read the PBCH.
[0093] PBCH decoding is always necessary in the server cell, whereas in the situation of section B.1 of the present invention, PBCH decoding of neighboring cells is always mandatory. In some situations, it may be necessary for the decoding of broadcast signaling that carries the actual transmitted SS block position in a server cell to be transported by means other than the PBCH. The PBCH can carry only the required master system information or minimum system information; other system information can be broadcast on other channels, such as PDSCH in LTE.
[0094] In an exemplifying mode and mode illustrated in Figure 5E, radio access node 22E generates an inter-node signal to send to another node, for example, neighbor node 22E '. The inter-node signal comprises the beam usage information as generated by the beam usage information generator 70E. The beam usage information specifies which of the
Petition 870190110414, of 10/30/2019, p. 62/114
45/75 nominal integer synchronization L of a set of bursts of synchronization signal block (SS) the node actually transmits synchronization signal blocks.
[0095] Figure 5E shows that the radio access node 22E comprises the inter-node signal handler 80, as well as the inter-node signaling interface (L / F) 82. In a new radio communications system, the inter-node signaling interface (L / F) 82 connects to an XN interface, which is analogous to the LTE interface X2. The beam usage information that is generated by the beam usage information generator 70E is provided to the inter-node signal handler 80, which in turn provides a suitable signal (where the beam usage information can be a information element) to the inter-node signaling interface (L / F) 82. The inter-node signaling interface (L / F) 82 then transmits the signal including the beam usage information to the radio access node 22E '.
[0096] In Figure 5E the radio access node 22E 'is the access node for the server cell for the wireless terminal 26E, while the radio access node 22E is associated with a neighboring cell. Radio access node 22E 'comprises an inter-node signaling interface (L / F) 82', which serves as an interface circuit for receiving the inter-node signal from radio access node 22E. As already explained, the inter-node signal received from the radio access node 22E comprises beam usage information that specifies which of the integer sync signal blocks L of a set of sync signal block bursts (SS) the radio access node 22E actually transmits synchronization signal blocks.
[0097] Figure 11 shows examples of actions or representative non-limiting steps performed by the radio access node 22E '. Action 11-1 comprises the radio access node 22E ', and the
Petition 870190110414, of 10/30/2019, p. 63/114
46/75 inter-node signaling interface (L / F) 82 ', in particular, which receives an inter-node signal from another node of the radio access network. As indicated above, the inter-node signal comprises beam usage information that specifies which of the integer L sync signal blocks of a set of burst bursts (SS) bursts the other access node by radio actually transmits blocks of sync signal. Upon receipt of the inter-node signal, as in action 11-2, the node processor 30E of the radio access node 22E 'generates another node information signal, for example, a neighbor node information signal, which comprises beam usage information received from, or to another node, for example, from, or to the radio access node 22E. As action 11-3, the node transmitter circuitry 34 of the radio access node 22E 'then transmits the other node information signal, for example, the neighbor node information signal that carries the beam usage information to the neighboring node, via a radio interface 24 to a wireless terminal 26E served by the radio access node 22E '.
[0098] Not only the radio access node 22E 'receives inter-node signaling from a radio access node 22E, but such inter-node signaling which includes beam usage information can be received from several other nodes. In such a typical case, the processor circuitry is additionally configured to generate the other node information signal to include the beam usage information for the various other nodes. Consequently, in serving to generate the node information list, the node processor 30 can serve as a neighbor cell list generator 84, as identified in Figure 5E. The neighbor cell list generator 84 of the radio access node 22E 'can generate either an intra-frequency neighbor cell list as shown in Table 2, or a
Petition 870190110414, of 10/30/2019, p. 64/114
47/75 neighbor cell inter-frequency list as shown in Table 3. Both such lists include beam usage information for one or more other nodes (for example, neighbors). The list (or lists) generated by the neighbor cell list generator 84 can be transmitted to the wireless terminal 26E by dedicated or broadcast signaling. Alternatively, the list generated by the neighbor cell list generator 84 can be transmitted to the wireless terminal 26E upon receipt of a request on demand by the wireless terminal 26E for the list, for example, for the beam usage information for a neighboring cell or node.
[0099] Table 3 is a mapping between the TX pattern index of SS block and list of neighboring intra-frequency cells; Table 4 is a mapping between the SS block TX pattern index and inter-frequency neighbor cell list.

[00100] In Table 2 and Table 3, it is assumed that 8 cells
Petition 870190110414, of 10/30/2019, p. 65/114
48/75 intra-frequency / inter-frequency neighbors are configured with their IDs for the 26E wireless terminal for intra-frequency / inter-frequency neighbor cell measurement. 8 is just an example, which could be any integer indicating the maximum bearable number of neighboring cells intra-frequency / inter-frequency.
[00101] The information in Table 2 and Table 3 must be signaled to the wireless terminal 26E in two different signals: one is for the purpose of intra-frequency measurement, for example, similar to SIB 4 in the LTE system; the other is for inter-frequency measurement purposes, for example, similar to SIB 5 in the LTE system. For example, the node can transmit the second information (for example, intraFreqNeighCelIList) including a physical cell ID and the actual transmitted pattern index. In addition, the node can transmit third party information (for example, interFreqNeighCelIList) including a physical cell ID and the actual transmitted pattern index. And, the second information and the third information can be included in different blocks of system information.
[00102] In addition, this information can also be signaled to the wireless terminal 26E in dedicated RRC signaling. If the 26E wireless terminal receives both broadcast and dedicated signaling about it, and these two signals have different contents, the information specified in the dedicated signaling must take effect.
[00103] In addition, if the information is signaled to the wireless terminal 26E in broadcast signaling, in addition to the way the network configures them, they can be sent to the wireless terminal 26E upon request by the wireless terminal 26E, at on-demand system information format, if the 26E wireless terminal wants to measure neighboring cells.
[00104] Figure 12 shows an example of actions or steps not
Petition 870190110414, of 10/30/2019, p. 66/114
49/75 representative limiters that can be realized by the wireless terminal 26E of Figure 5E. Action 12-1 comprises the wireless terminal 26E receiving, via a radio interface from a server node of a radio access network, the beam usage information for another node of the radio access network. As indicated above, such information of use beam to another node can be included in the other node information signal. Action 12-2 comprises the terminal processor 40E of the wireless terminal 26E using the beam usage information to determine which of the integers L of nominal sync signal blocks the other node transmits actual sync signal blocks to. Action 12-3 comprises terminal processor 40 of wireless terminal 26E to read the blocks actually transmitted.
[00105] Thus, as a result of action 12-2, as action 12-3 the wireless terminal 26E, which knows the sync signal blocks actually transmitted, and thus knows the actual transmission pattern as action 12 -3, it can read those blocks actually transmitted, that is, synchronization signal blocks actually transmitted from neighboring node 22E. Based on this knowledge of the actual transmission pattern and reception of sync signal blocks within a sliding detection time window (for example, 20 milliseconds), such as action 12-4, the 26E wireless terminal determines beam identifiers (e.g., beam indexes) that correspond to the sync signal blocks received in the order of the sync signal block reception within the detection window. The sliding window is established to correlate with the periodicity of set of bursts of synchronization signaling block (SS). In the sliding measurement window, wireless terminal 26E captures the entire sync signal block. Therefore, the 26E wireless terminal can determine the
Petition 870190110414, of 10/30/2019, p. 67/114
50/75 beam identifiers without having to reach the PBCH that can be provided in the synchronization signal blocks.
[00106] Thus, as indicated above, when the UE receives the actual SS block transmission position information (ie, beam usage information), the wireless terminal 26E knows the corresponding SS block index for each actual SS block transmitted. This is explained by way of example as follows: assuming in a practical case for a given carrier frequency, the nominal SS block number (L) is 4, the wireless terminal 26E obtains the actual SS block transmission position as [1 0 1 0], which means that there are actual SS block transmissions in the second and fourth nominal SS block positions. Since the SS burst transmission has its periodicity, when the wireless terminal 26E initiates a measurement procedure and captures an entire SS burst, the wireless terminal 26E obviously knows which SS block transmitted belongs to which beam. But if the 26E wireless terminal captures part of the SS burst set, for example, capturing only one real SS block transmission, the 26E wireless terminal knows that it must capture two SS block transmissions and lose one, and determines that the block of captured SS belongs to the 4th beam.
[00107] The position (or positions) of the nominal SS block (or blocks) (and / or the position (or positions) of the burst (or bursts), and / or the position (or positions) of the set (or sets) of bursts SS) can be determined based on the maximum number of the SS L block (or blocks). In addition, the position (or positions) of the actual SS block (or blocks) (and / or the position (or positions) of the burst ( or bursts), and / or the position (or positions) of the SS burst set (or sets) can be determined based on the maximum number of the SS L block (or blocks). Namely, the wireless terminal can identify the position (or positions)
Petition 870190110414, of 10/30/2019, p. 68/114
51/75 of the nominal SS block (or blocks) and / or the actual transmitted SS block (or blocks) based on the maximum SS L. block (or blocks) number.
[00108] Namely, a terminal can receive wireless information (for example, second information and / or third information) including a list of physical cell identifiers (ID) and the actual transmitted SS block patterns. And, each of the actual transmitted SS block patterns can be used to indicate a position (or positions) of the actual transmitted SS block (or blocks) within the SS burst defined in an associated cell by each of the physical cell identifiers . For example, for the initial selection of the cell, the position (or positions) of the real transmitted SS block (or blocks) can be configured using the PBCH. In addition, for example, for the measurement of neighboring cells, the information (for example, the second information and / or the third information) including a list of physical cell identifiers (ID) and the actual transmitted SS block patterns can be transmitted using the system information message. Here, the information (for example, the second information and / or the third information) including a list of physical cell identifiers (ID) and the actual transmitted SS block patterns can be transmitted in the server cell. In addition, information (for example, second information and / or third information) including a list of physical cell identifiers (ID) and the actual transmitted SS block patterns can be transmitted only to the neighboring cell.
B.4 Identification of used bundles: using other signals
[00109] Measurements of neighboring cells are related to reference signal measurements. Thus, in another exemplary mode and mode, the SS block index information can also be carried by reference signal (or signals). Per
Petition 870190110414, of 10/30/2019, p. 69/114
52/75 example, reference signal patterns can be used to indicate the SS block index; or the reference signal can be checked by CRC and scrambled with SS block index information via XOR operation, so blind detection can help the UE to obtain SS block information.
[00110] In addition, in a new radio (NR) system, reference signals for measuring cell / beam quality include additional SSS and CSI-R, and even a third synchronization signal (TSS). Any or any combination can be used to carry the SS block index; in the case of a combination, it is predefined which reference signal carries which part of the SS block index, for example, assuming the actual SS block index is 4, which can be expressed as [0 1 0 0], then it can be predefined that SSS carries [0 1] and CSI-RS carries [0 0],
[00111] One purpose for informing a wireless terminal of the actual transmitted SS block is to enable the wireless terminal to know that some nominal SS block positions that are not used for actual transmission can be used for another data / signal transmission. This does not necessarily mean that these unused positions for real SS block transmission are actually used for other information transmission. Consequently, in an exemplifying mode and mode, the radio access node can also transmit the actual NRPDSCH transmission pattern information (or another channel, for example, NR-PDCCH, or other signals, such as reference signals) within the burst of signaling block (SS) defined at the wireless terminal. Such standard information can take the form of a practical standard or the format of a relative standard. For example, suppose the actual SS block transmission pattern within a set of SS bursts is [1 0 1 0 0 0 0 0 0], then the positions of the nominal SS block value that are not used
Petition 870190110414, of 10/30/2019, p. 70/114
53/75 for SS block transmission are 2 ^a , 4 ^a , 5 ^a , 6 ^a , 8 ^a . However, these positions are not necessarily used for transmitting NRPDSCH. But even assuming that ^the 4, 5 ^and 6 positions are, in fact, used for real NR-PDSCH transmission. Then, the NR-PDSCH transmission pattern information within the burst set of synchronization signaling block (SS) could be [0 0 0 1 1 1 0 0], in the practical pattern format, or [0 1 1 1 0 0], in relative pattern format, because relative pattern means the time index at the top of the indicated block transmission pattern actual SS. Such information can be broadcast to the wireless terminal, or specifically signaled to the wireless terminal or signaled to the UE on the NR-PDCCH, for example, the common NR PDCCH.
[00112] Certain units and functionalities of node 22 and wireless terminal 26 are, in examples of modalities, implemented by electronic machines, computers and / or circuits. For example, node processors 30 and terminal processors 40 of the example modalities described and / or covered herein can be included in the computer circuitry of Figure 13. Figure 13 shows an example of such electronic machines or circuits, whether they are nodes or terminals, comprising one or more processor circuits 90, program instruction memory 91, other memory 92 (for example, RAM memory, cache memory, etc.), input / output interfaces 93, peripheral interfaces 94, support 95 and buses 96 for communication between the units mentioned above.
[00113] Program instruction memory 91 may comprise coded instructions that, when executed by one or more processors, perform actions that include, but are not limited to, those described here. Thus, it is understood that each of the node processor 30 and the terminal processor 40, for

54/75 example, includes a memory in which non-temporary instructions are stored for execution.

Support circuits 95 can be coupled to processors 90 to support the processor in a conventional manner. These circuits include cache, power supplies, clock circuits, input / output circuits and subsystems, and the like.
[00115] Although the processes and methods of the revealed modalities can be discussed as being implemented as a software routine, some of the method steps that are presented in them can be performed in hardware, as well as by a processor running software. In this way, the modalities can be implemented in software as executed in a computer system, in hardware such as an application specific integrated circuit or other type of hardware implementation, or a combination of software and hardware. The software routines of the revealed modalities can be executed in any computer operating system, and can be executed using any CPU architecture. The instructions for such software are stored on non-transitory, computer-readable media.
[00116] The functions of the various elements that include functional blocks, including, but not limited to those identified or described as a computer, processor or controller, can be provided through the use of hardware such as hardware circuit and / or hardware capable of running software in the form of instructions

[00117] In terms of hardware implementation, functional blocks may include or include, but are not limited to, digital signal processor (PSD) hardware, reduced instruction set processor, hardware circuits (for example, digital or analog) including, but not limited to, application-specific integrated circuits (ASICs) and / or field programmable port arrays (FPGAs), and (where applicable) state machines capable of performing such functions.
[00118] In terms of implementation by computer, a computer is generally considered to be a device comprising one or more processors or one or more controllers, and the terms computer, processor and controller can be used interchangeably in the present invention. When provided by a computer or processor or controller, functions can be provided by a single computer or dedicated processor or controller, by a single computer or shared processor or controller, or by a plurality of individual computers or processors or controllers, some of which can be shared or distributed. In addition, the use of the term processor or controller should also be interpreted as referring to other hardware capable of performing such functions and / or running software, such as the example hardware mentioned above.

[00120] Nodes that communicate using the air interface also have adequate radio communication circuits. In addition, the technology can additionally be considered to be fully incorporated into any form of computer-readable memory, such as solid-state memory, magnetic disk, or optical disk containing an appropriate set of computer instructions that can cause a processor to perform techniques described here.
[00121] It should be noted that the technology described here is designed to resolve issues centered on radio communications and is necessarily rooted in computer technology and overcomes the problems that arise specifically in radio communications. In addition, in at least one of its aspects, the technology described here improves the functioning of the basic function of a wireless terminal and / or the node itself so that, for example, the wireless terminal and / or the node can operate more effectively through the prudent use of radio resources. For example, the technology described here overcomes inefficiencies in telecommunications operations by providing knowledge of wireless terminal advancement for which of the L integers of the sync signal blocks of a set of sync signal block (SS) bursts o node actually transmits sync signal blocks. Such pre-knowledge of actual sync signal block positions not only streamlines the processing of the set of sync signal block (SS) bursts, but also the measurements that are

57/75 intensely performed on a beam-by-beam basis. In addition, by providing techniques for identifying synchronization signal block indices and / or beam indices, the wireless terminal can correlate energy measurements in reference signals to the actual beams to which the measurements refer and thus provide an enhanced evaluation of signal strength to perform cell selection, cell reselection and / or transfer determinations and the like. [00122] Measurements of neighboring cells of the NR system. In order to (A) signal the actual SS block positions to UE, and (B) obtain SS block index information for neighboring cell measurement, the technology described here advantageously includes:
• Consideration of compensation between signal overload and wireless terminal complexity, having several models with different compensation preferences.
• For no decoding of PBCH information when measuring neighboring cells, the PBCH implicitly carries the index information. The wireless terminal does not need to decode the PBCH in order to obtain the information. Instead, since the wireless terminal detects PBCH, the wireless terminal can obtain index information. Therefore, the technology described here provides a new method of obtaining control index information through PBCH detection, and also adds an extra PBCH detection step when measuring neighboring cells, which is different from all measurement procedures. of existing neighboring cells.
• Combines project resolution sections (A) and (B) to have a unified project in order to minimize system complexity.
[00123] The technology described here includes, but is not limited to, the following exemplifying modes and modalities.
