Descriptive Report of the Invention Patent for ’’ TRANSMISSION AND RECEPTION OF SYNCHRONIZATION SIGNS FOR RADIO SYSTEM ”.
TECHNICAL FIELD [0001] This application claims the priority and benefit of US provisional patent application No. 62 / 454,016, filed on February 2, 2017, entitled SYNCHRONIZATION SIGNAL TRANSMISSION AND RECEPTION FOR RADIO SYSTEM, which is hereby incorporated by reference in its entirety.
[0002] The present technology refers to wireless communications, and particularly to methods and apparatus for transmitting and receiving system information (IS) in wireless communications.
BACKGROUND [0003] 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) proposed to define technical specifications and globally applicable technical reports for wireless communication systems, current and future. The LTE (Long Term Evolution) and LTE-A (LTE Advanced, or LTE Advanced) technologies, both developed by 3GPP, are projects to improve a previous standard of phones or mobile devices of the universal system. mobile telecommunications (UMTS, from Universal Mobile Telecommunications System) to deal with future requirements.
[0004] Work began at the International Telecommunication Union (ITU) with the 3GPP responsible for developing
Petition 870190068092, of 07/18/2019, p. 39/113
2/71 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) was approved, the Study on New Radio Access Technology, or study on new radio access technology. The NR development agenda and study situations are summarized in document RP-161596, Revision of SI: Study on New Radio Access Technology, produced from the 3GPP TSG RAN Meeting # 73, in New Orleans, from 19 to 22 September 2016, which is incorporated herein, as a reference. To meet the requirements of 5G technology, changes about the LTE 4G system have been proposed for study, such as using the higher frequency spectrum (for example, 6 GHz, 40 GHz or up to 100 GHz), scalable numerology (for example, spacing between different subcarriers (SOS), 3.75 KHz, 7.5 KHz, 15 KHz (current LTE), 30 KHz etc., up to possibly 480 KHz), initial beam-based access (a traditional cell may contain several due to the formation particular beam pattern adopted).
[0005] Here, three PSS (primary sync signal) strings provide cell ID identification (0 to 2); and SSS (secondary sync signal) strings provide group ID of cell IDs (0 to 167). Therefore, in total, 168 * 3 504 physical cell IDs (PCI) are supported in the system. In a RAN1 # 87 meeting, it was pointed out that the number of IDs provided by the NR PSS / SSS strings should be studied. See, for example, the Chairman's Notes of the 3GPP RAN1 meeting # 87, which are incorporated herein, as a reference. 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 Chairman's Notes of the 3GPP RAN1 meeting # 86, which are incorporated herein, as a reference.
[0006] In the next generation new radio (NR) technology, it is
Petition 870190068092, of 07/18/2019, p. 40/113
3/71 predicted that a cell corresponds 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.
[0007] It was agreed at the RAN1 # 86bis meeting (see, for example, the Chairman's Notes to the 3GPP RAN1 # 86 meeting which are incorporated by reference) that:
The 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 one 'SS block'
One or multiple 'SS blocks' that make up a burst of sync signal, or 'SS burst'
One or multiple 'bursts of SS ^! make up a set of burst bursts, or 'set of SS bursts' o The number of SS bursts in a set of SS bursts is finite.
[0008] 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) [0009] Figure 3 is an exemplary NR SS block structure, according to meeting RAN1 # 86bis. In Figure 3, a
Petition 870190068092, of 07/18/2019, p. 41/113
4/71 series of sync signal bursts represents a set of SS bursts. Additional detailed examples are illustrated in the report R12-1610522, 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, the content of which is incorporated herein as a reference. According to the report RI-1611268, Considerations on SS block design, ZTE, ZTE Microelectronics, Reno, Nevada, USA, of the meeting held from 14 to 18 of 2016, whose content is incorporated by reference, the structure of the block of SS in Figure 3 can be as shown in Figure 4.
[0010] Probably, a synchronization signal block will have a fixed multiplexing structure, which means that once the information and / or signal is decided, each of these will have its fixed position by time or frequency in the SS block. Here, the PSS / SSS signals and the PBCH channel have different periodicities due to different detection performance requirements and different methods of eliminating channel distortion.
[0011] The technology disclosed here refers to design methods for NR synchronization, for example, different types of SS blocks with fixed multiplexing structure, as well as new structures and operations for the access node and wireless terminal they use these new sync signal block structures.
[0012] In one of its aspects, the technology disclosed here refers to user equipment that comprises a reception circuit. The receiving circuit is configured to receive, from a base station device, a radio resource control signal that includes information that is used to indicate whether a primary sync signal, a secondary sync signal, a physical transmission channel and a reference signal to decode the

The primary sync signal and the secondary sync signal are used to identify the identity of a physical cell, and the physical transmission channel is used to transmit frame identification number information in the system.
[0013] In another aspect, the technology disclosed here refers to a method on user equipment. In a basic mode, the method comprises receiving, from a base station device, a radio resource control signal that includes information that is used to indicate whether a primary sync signal, a secondary sync signal, a physical radio channel. transmission and a reference signal to decode the physical transmission channel are transmitted in a block consisting of a constant number of OFDM symbols.

[0037] For use in the present invention, the term core 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.
[0038] 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. Other terms used to refer to wireless terminals and non-limiting examples of such devices may include user equipment terminal, UE, mobile station, mobile device, access terminal, subscriber station, mobile terminal, remote station, user terminal , terminal, subscriber unit, cell phones, smart phones, personal digital assistants (PDA's, Personal Digital Assistant), laptop computers, netbooks, tablet computers, diPetition readers 870190068092, from 07/18/2019, p. 48/113
11/71 e-readers, wireless modems, among others.
[0039] For use in the present invention, the term access node, node or base station can refer to any device or group of devices that facilitates wireless communication or otherwise provides an interface between a wireless terminal and a system telecommunication A non-limiting example of an access node may include, in the 3GPP specification, a B node (NB), an evolved B node (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 here can be used in other types of wireless communication systems.
[0040] 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.
[0041] For use in the present invention, the term cellular network can refer to a network distributed over several cells, each cell being served by at least one fixed location transceiver, such as a
Petition 870190068092, of 07/18/2019, p. 11/113
12/71 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 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.
[0042] Here, hierarchical synchronization signals, that is, primary synchronization sequences (PSS) and secondary synchronization sequences (SSS) provide approximate time / frequency synchronizations, physical layer cell ID (PCI) identification ID), subframe timing identification, frame type differentiation (FDD or TDD) and cyclic prefix overload identification (CP, from Cyclic Prefix). On the other hand, in such systems, a physical transmission channel (PBCH) provides additional information, such as the system frame identification number (SFN) and essential system information for a wireless user terminal (UE) to obtain information to access the network. An initial access procedure for such a system is illustrated in Figure 1.
[0043] Three PSS (primary sync signal) strings provide cell ID identification (0 to 2); and SSS (secondary sync signal) strings provide group ID of cell IDs (0 to 167). Therefore, in total, 168 * 3 ™ 504 physical cell IDs (PCI) are supported in the system.

13/71 [0044] As stated in US provisional patent application No. 62 / 443,622, filed on January 6, 2017, hereby incorporated in full by reference, a PBCH can be ignored in an SS block and, in this case, the features originally used for PBCH in the fixed multiplexing structure can be used for other purposes, for example, for SS repetition to improve SS detection performance. In some of its exemplifying aspects, the technology disclosed here specifies how a wireless terminal can know which SS block has the type of information ignored in the fixed multiplexing structure, and how the wireless terminal can know its corresponding behavior in such a situation.
[0045] Figure 5A shows an example of a communication system 20A in which the radio access node 22A communicates via the air or radio interface 24 (for example, the Uu interface) with the wireless terminal 26. According to mentioned above, radio access node 22A can be any node suitable for communication with wireless terminal 26, such as a base station node, or eNodeB (eNB) or gNodeB or gNB, for example. Node 22A 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.
[0046] The 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 are also called a transmitter circuit. terminal 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
Petition 870190068092, of 07/18/2019, p. 51/113
14/71 can comprise (for example) a screen as a touch screen that can display information to the user and receive information entered by the user. User interface 48 can also include other types of devices, such as a speaker, a microphone or a tactile feedback device, for example.
[0047] For both the radio access node 22A and the radio interface 24, the respective transceiver circuits 22 include one or more antennas. The respective transmitting circuits 34 and 44 can comprise, for example, one or more amplifiers, a modulation circuit and other conventional transmission equipment. The respective receiver circuits 36 and 46 can comprise, for example, amplifiers, demodulation circuits and other conventional receiver equipment.
[0048] In the general operating node, access node 22A and wireless terminal 26 communicate with each other via radio interface 24 using predefined information settings. As a non-limiting example, radio access node 22A and wireless terminal 26 can communicate via radio interface 24 using information boards can be configured to include multiple channels. In LTE (Long Term Evolution) technology, 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 breaks. 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 symbol (single-carrier frequency division multiple access). carrier frequency division
Petition 870190068092, of 07/18/2019, p. 11/113
15/71 only) 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, range, mlni- 5G range, for example).
[0049] To serve 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 handlers information. For an exemplary implementation in which information is communicated via frames, the information handler for radio access node 22A 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.
[0050] In the technology disclosed herein, access node 22A comprises a sync signal block generator 60. The sync signal block generator 60, which can be performed by node processor 30, serves to generate multiple types of synchronization signal blocks for transmission at least partially interleaved through the radio interface 24. Each type of synchronization signal block comprises a unique combination of types of information, as described here. Transmitter circuit 34 transmits the sync signal blocks generated by the sync signal block generator 60 in an at least partially interconnected manner
Petition 870190068092, of 07/18/2019, p. 53/113
16/71 silenced via radio interface 24. Thus, wireless terminal 26 does not receive a constant stream of sync signal blocks all of the same type, but occasionally receives one or more sync signal blocks of different types in a series of synchronization signal block transmissions.
[0051] The synchronization signal blocks can be transmitted in a frame structure that can be performed as a matrix or grid of time and frequency resources (carrier / subcarrier). For example, Figure 6 illustrates a basic transmission frame 62 in which time resources are shown along a geometric axis X and the frequency (for example, subcarriers) is arranged along a geometric axis Y. An example of sync signal block 64 is shown included in frame 62. There may be different subcarrier spacing in different systems depending on how the frame is constructed. For a given subcarrier spacing, preferably all the sync signal blocks are the same size in terms of the same number of resources that comprise the sync signal block. This same number of features can be considered the reference design of the sync signal block. For example, an integer N of OFDM symbols can comprise the sync signal blocks for a given subcarrier spacing. For example, for a given frequency band, the (one) sync signal block can correspond to N symbols (for example, OFDM symbols). Here, the number N can be a constant. In addition, for a given frequency band, one (o) block of synchronization signal can correspond to N symbols based on a standard subcarrier spacing. For example, the standard subcarrier spacing can be defined in advance for a given frequency band by the specifications. For example, the standard spacing of
Petition 870190068092, of 07/18/2019, p. 54/113
17/71 subcarrier can be 15 kHz. Although, preferably, the number of resources used for a sync signal block is fixed, the “relative dimensions of the sync signal block along the grid's time and frequency axes may vary according to different implementations of the grid design. reference.
[0052] Regarding the above, it should be considered, based on Figure 4, that the content of a synchronization signal block can be constructed or multiplexed by time division, frequency division or with the use of a hybrid of time division and frequency division. For example, in the illustration of Time Division Multiplexing (TDM) of Figure 4, symbols 0 to 2 can be allocated to a primary synchronization signal (PSS), symbols 3 to 5 can be allocated. allocated to a secondary synchronization signal (SSS), and symbols 6 to 9 can be allocated to a physical transmission channel (PBCH). Specifically, the one or more synchronization signal blocks may comprise one or more symbols that correspond to one or more signals and / or one or more channels.
[0053] As indicated above, the sync signal block generator 60 generates multiple types of sync signal blocks, and each sync signal block type comprises a unique combination of types of information, as described here. The types of information that can be included in a sync signal block can include:
[0054] synchronization signals (primary synchronization signals (PSS), secondary synchronization signals (SSS) and / or tertiary synchronization signals (TSS)), [0055] one or more physical transmission channels (PBCH), [0056 ] first reference signals (for example, one or more first reference signals used for a measurement),
Petition 870190068092, of 07/18/2019, p. 55/113
18/71 [0057] second reference signals (for example, one or more second reference signals used for decoding the PBCH), [0058] signaling (DCI, Downlink Control Information, or downlink control information) transmitted by physical downlink control channel (PDCCH, Physical Downlink Control Channel), [0059] data transmitted over the physical downlink shared channel (PDSCH, Physical Downlink Shared Channel), [0060] data transmitted over the random access physical channel (PRACH, from Physical Random Access Channel), [0061] pagination information.
[0062] The multiplexing structure of the synchronization signal blocks can be fixed. For example, the structure of the fixed multiplexing of the synchronization signal blocks can be defined in advance by a specification. For example, the multiplexing of the sync signal blocks (for example, PSS (which can be mapped to symbols 0 to 2), SSS (which can be mapped to symbols 3 to 5), TSS ( which can be mapped to symbols 6 and 7), the PBCH (which can be mapped to symbols 8 to 10), the first reference signs (which can be mapped to the symbol 11), the second reference signs ( which can be mapped to symbols 8 to 10), the signaling transmitted by PDCCH (which can be mapped to symbols 12 and 13) and / or data transmitted by PDSCH) can be defined as the fixed multiplexing structure. In addition, one or more types of sync signal blocks can be defined based on the fixed multlplexing structure. For example, one or more information defined as the fixed multiplexing structure may not be transmitted (for example, not mapped or ignored). For example, the PBCH may not be transmitted for a certain time on the signal blocks of
Petition 870190068092, of 07/18/2019, p. 56/113
19/71 synchronization. In addition, the PBCH and the second reference signal may not be transmitted for a certain time in the synchronization signal blocks. For example, only the PSS and SSS can be transmitted, over a period of time, in the synchronization signal blocks. In addition, only the PSS, SSS and PBCH can be transmitted, over a period of time, in the synchronization signal blocks. The details of the different types of synchronization blocks will be described below.
[0063] Regarding the above, tertiary synchronization signals (TSS) are synchronization signals that are provided by the access node in addition to the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). In addition, as noted above, it is also possible to have multiple physical transmission channels, for example, PBCH1 and PBCH2.
[0064] Table 1 below shows the different types of sync signal blocks that can be generated by the sync signal block generator 60, and particularly shows by the symbol * the unique combination of types of Information that can be included on each sync signal block. As described above, the unique combination of types of information (also, the ♦ symbol) can be defined in advance by a specification. The number of types of sync signal blocks and types of information in Table 1 are not exhaustive, and are included for simplified example purposes only.

20/71 * * [0065] Thus, as shown in Table 1, SSB type 1 (that is, a type 1 of SSB) includes five types of information: PSS, SSS, TSS, PBCH1 and PBCH2. Figure 7A also illustrates type 1 SSB and shows that the entire resource allocation for the type 1 SSB sync signal block is used for a combination of PSS, SSS, TSS, PBCH1 and PBCH2. In contrast, Figure 7B shows that the type 2 SSB sync signal block (that is, a type 2 SSB sync), although it is the same size as the type 1 SSB sync block, includes content only for PSS, SLT, TTS and PBCH1. As explained here, from the point of view of the type 1 sync signal block, a field in the sync signal block of Figure 7B is ignored or does not conform to PBCH2.
[0066] Figure 8 shows examples of basic steps or steps that can be performed by access node 22A of Figure 5A. Step 8-1 comprises the access node using the processor circuit to generate multiple types of sync signal blocks for transmission at least partially interleaved through a radio interface, each type of sync signal block comprising a combination different types of information. For example, the sync signal block generator 60 of Figure 5A can generate both the type 1 SSB sync signal blocks of Figure 7A and the type 2 SSB sync signal blocks of Figure 7B. Step 8-2 comprises the node transmitting circuit 34 at least partially interleaving the transmission of the multiple types of synchronization signal blocks through the radio interface to at least one wireless terminal.
[0067] The wireless terminal 26 of Figure 5A comprises a terminal receiving circuit 46 and a terminal processor 40. Terminal receiving circuit 46 receives from an access node, in a
Petition 870190068092, of 07/18/2019, p. 11/113
21/71 less partially interspersed, sync signal blocks of different types through the radio interface. As explained above, each type of sync signal block comprises a unique combination of different types of information. The terminal processor 40 comprises a sync signal block type detector 70, which is configured to determine which of the multiple sync signal block types a received sync signal block belongs to.
[0068] Figure 9 thus shows basic steps or steps that can be performed by wireless terminal 26 in Figure 5A. Step 9-1 comprises receiving, from an access node, in a form at least partially interleaved, different types of synchronization signal blocks through a radio interface. Step 9-2 comprises the wireless terminal 26 using a processor circuit, for example, the sync signal block type detector 70, to determine which of the multiple sync signal block types is a sync signal block. received synchronization belongs.
[0069] It should be noted that, for a given carrier frequency band, the sync signal blocks of all types are the same size (for example, the same number of frame resources), and are essentially formatted or configured so that, from one type of sync signal block to another, the same resources are partitioned in a similar way. For example, in terms of size, the fields comprising the sync signal blocks of Figure 7A and Fig. 7B are the same and are similarly located within the sync signal block.
[0070] Figure 5B illustrates an embodiment and mode of access node 22B in which the sync signal block generator 60B designates a first type of sync signal block as a standard sync signal block, and other types of blocks of
Petition 870190068092, of 07/18/2019, p. 59/113
22/71 sync signal (e.g., a second type of sync signal block and / or a third type of sync signal block) as non-standard sync signal blocks. In this way, the sync signal block generator 60B to Figure 5B is shown generating both standard and non-standard sync signal block types. Preferably, the first type or standard type of sync signal block contains information for a fixed number of different types of information and is considered a complete or substantially complete sync signal block (like the sync signal block of Figure 7A ). That is, the first type or standard type of synchronization signal block can contain complete information (that is, all information) defined as the fixed multiplexing structure. However, from the standpoint of the standard sync signal block type, a non-standard type of sync signal block contains information for only a subset of the types of information included in the standard sync signal block, as described above. For example, the sync signal block of Figure 7B includes only information for PSS, SSS, TTS and PBCH (for example, PBCH1) (but does not contain information for PBCH2, that is, it does not contain other information included in the type of the standard sync signal).
[0071] Thus, from one type of sync signal block to another, to a non-standard sync signal block, essentially the same resources (for example, time resources and / or frequency resources) are partitioned or allocated to the same types of information as in the standard sync signal block, but only a subset of these resource allocations is used in the form of the standard sync signal block. Resource location allocations or partitions are referred to here as fields (or symbols (for example, OFDM symbols)). That is, in the
Petition 870190068092, of 07/18/2019, p. 60/113
23/71 standard sync signal block of Figure 7A there is a PSS field, an SSS field, a TSS field, a PBCH1 field and a PBCH2 field. The non-standard sync signal block in Figure 7B has the same fields, but the PBCH2 field is not filled with information from PBCH2.
[0072] The sync signal block generator 60B of Figure 5B generates a standard sync signal block comprising a predetermined number of fields corresponding respectively to a predetermined number of different types of information. For example, as described above, a predetermined number of fields corresponding to a predetermined number of different types of information respectively can be defined in advance by the specification. For example, the correspondence between the type of information and the field is assigned (for example, determined) by defining the type of sync signal block, so a standard sync signal block type is expected to have values of field that conform to the standard sync signal block type definition. That is, it is expected that all fields of the standard sync signal block type have valid information according to the type of information associated with the field by defining the type of sync signal block. The definition of the specific type of synchronization signal block can be determined, for example, by reference to information such as that in Table 1.
[0073] The sync signal block generator 60B of Figure 5B also generates one or more types of non-standard sync signal blocks. In the non-standard sync signal block type, only a subset of the fields includes information in accordance with the standard sync signal block type. That is, the type of information included in one or more of the fields outside subPetition 870190068092, of 7/18/2019, p. 61/113
24/71 set is not the type of information anticipated or expected according to the standard sync signal block type definition. In this way, fields outside the subset cannot be decoded in the form of the standard sync signal block type.
[0074] The wireless terminal of Figure 5B receives and, using the sync signal block type detector 70, decodes a sync signal block from a standard sync signal block type comprising a predetermined number of fields corresponding to a predetermined number of different types of information respectively in accordance with the standard type of sync signal block. In addition, the wireless terminal in Figure 5B also receives and (again using the sync signal block type detector 70) decodes a non-standard sync signal block type, with only a subset of the fields including information accordingly. with the standard sync signal block type.
[0075] For a non-standard sync signal block type, fields outside the subset, that is, fields that do not include information in accordance with the standard sync signal block type and that cannot be decoded in the form of the standard sync signal block type, they may appear to be ignored or unused (for example, information is not transmitted) by the access node. In some examples of modalities and modes, such fields may, in fact, not be used, or contain null, empty or meaningless values. For example, it can be assumed that the one or more fields of the non-standard sync signal block type are unused (for example, information corresponding to one or more fields is not transmitted). It can also be assumed that the one or more fields of the type of the non-standard sync signal block contain null, empty or meaningless values (for example,
Petition 870190068092, of 07/18/2019, p. 62/113
25/71 all O ”or all 1, for example). That is, the one or more fields set to null, empty or meaningless values (for example, all 0 or all ’’ 1 ’’, for example) can be contained in the type of the non-standard sync signal block. But in other examples of modalities and modes, these non-standard sync signal block type fields can be advantageously used, as explained below. For example, it can be assumed that the one or more fields of the non-standard sync signal block type are used as one or more fields of other information (for example, one or more fields of other information included in the type of the sync signal non-standard). For example, as described below, it can be assumed that one or more fields of the non-standard sync signal block type are used for one or more repetitions of one or more fields of other information.
[0076] In exemplary access node 22C of Figure 5C, node processor 30 includes a sync signal block generator 60C that repeats certain SSB information, already included in another field of the sync signal block, in the apparently fields ignored from a non-standard sync signal block type. That is, the sync signal block generator 60C of Figure 5C includes, in one or more fields that are outside the subset of fields that adapt to the type of standard sync signal block, repeated information that comprises a repetition of the information transmitted in a subset field. For example, if the sync signal block of Figure 7A is considered the standard sync signal block and the sync signal block of Figure 7B is considered a type of non-standard sync signal block in relation to the signal block. of Figure 7A, Figure 7C shows that the 60C sync signal block generator of Figure 5C generated a type of sync signal block
Petition 870190068092, of 07/18/2019, p. 63/113
26/71 non-standard timing to include, in the field that would otherwise be allocated to PBCH2 (that is, any information included in the type if the standard sync signal block), information that essentially repeats the PSS. Information other than the PSS information can be repeated, since the PSS repetition is provided as an example only. In some examples of modalities and modes, the synchronization signal block can be defined to include some or all of the information of a transmission channel, such as PDSCH, PDCCH and / or PRACH, so that in the example of modality and mode of Figure 5C the repeated information may, in some cases, be information from a transmission channel.
[0077] In example access node 22D of Figure 5D, node processor 30 includes a 60D sync signal block generator which, in one or more fields apparently ignored of a non-standard sync signal block type, includes instead, a signal or data that is not otherwise included in a standard sync signal block type field. In this way, the sync signal block generator 60D of Figure 5D is shown as a generator that includes signal and / or data, otherwise not yet included, in a sync signal block of a type of sync signal block. non-standard synchronization. For example, if the sync signal block of Figure 7A is considered the standard sync signal block and the sync signal block of Figure 7B is considered a type of non-standard sync signal block in relation to the signal block. of Figure 7A, Figure 7D shows that the 60D sync signal block generator of Figure 5D generated a type of non-standard sync signal block to include, in the field that would otherwise be allocated to PBCH2, information from signal and / or data that is not yet included in the sync signal block.
Petition 870190068092, of 07/18/2019, p. 64/113
27/71 [0078] As examples, the signal information and / or data that can be included in the 60D sync signal block generator of the access node of Figure 6D in the non-compliant fields of the sync signal block type non-standard may comprise one or more of: (1) at least partial content of a physical downlink control channel (PDCCH); (2) at least partial content of a downlink shared physical channel (PDSCH); and (3) at least partial content of a physical random access channel (PRACH). For example, it can be assumed that the one or more non-standard sync signal fields are used as one or more PDCCH, PDSCH and / or PRACH fields. For example, it can be assumed that the one or more fields of the non-standard sync signal are used as one or more fields of PSS, SSS, TTS, PBCH, the first reference signals and / or the second reference signals.
[0079] For examples of modalities and modes in which null or meaningless information (for example, all 0 or all 1, for example) are included in the fields of a type of non-standard sync signal block, the wireless terminal 26 does not obtain useful information from these fields. But in situations where significant information (repetitive SSB information in the case of Figure 7C and non-SSB information in the case of Figure 7D) is included in these fields, the sync signal block type detector 70 of the wireless terminal 26 is pre-configured to know the meaning of these fields and to obtain meaningful information from them. For example, the resources used by the signal / channel / signaling / data ignored in an SS block can be used by other signals / channels / signaling / data, for example, in the repetition format of other signals / channels / signaling / data ( in the form of Figure 7C); or in the format to always be used by a PDCCH and / or a PDSCH and / or
Petition 870190068092, of 07/18/2019, p. 65/113
28/71 a PRACH (that is, other information) for transmission (in the form of Figure 7D). Wireless terminal 26 assumes a fixed predefined resource reuse format for each type of SS block structure, thus allowing the wireless terminal to obtain additional information from the non-standard sync signal block type.
[0080] In the above description it was assumed that the type of standard sync signal block is type 1 in Table 1, and that an example of a type of non-standard sync signal block is type 2 in Table 2. it should be understood, however, that such choices are for example purposes only, and that the type of standard sync signal block may be different from the type 1 in Table 1, and the type of non-standard sync signal block may be different from type 2. In this last aspect, the non-conforming field that is outside the subset of fields that conform to the type of standard sync signal block can be other than PBCH2. For example, type 2 in Table 1 could be chosen as the standard sync signal block type and type 3 could be chosen as a non-standard sync signal block type, with the result that the type field non-standard sync signal block corresponding to the TSS field can be null or (as in the case of Figure 7C) be filled with repetitive SSB information, or (as in the case of Figure 7D) be filled with signaling information and / or non-SSB data.
[0081] In addition to that described above, in some examples of modalities and modes, the synchronization signal block generator can process different frequency bands differently in terms of generation and transmission of the multiple types of synchronization signal blocks. For example, Figure 5E shows an access node 22E in which the sync signal block generator 60E generates different sync signal block schemes for bands
Petition 870190068092, of 07/18/2019, p. 66/113
29/71 of different frequencies, each sync signal block scheme having a different set of different types of sync signal blocks.
[0082] For example, as shown in Figure 11, the 60E sync signal block generator of access node 22E can generate a first set of different types of sync signal blocks in a first frequency band, according to the first SSB scheme 81, and also generate a second set of types of synchronization signal blocks, according to a second SSB scheme 82, for a second frequency band. For example, the first frequency band may include frequencies of 6 GHz and higher, in which the 60E sync signal block generator generates a first set of sync signal blocks including types 1, 2 and 4 of synchronization signal blocks (see Table 1). But for the second frequency band below 6 GHz, the sync signal block generator 60E can generate a second set of sync signal block types to include sync signal block types 2, 3 and 4. In the first set, the type 1 sync signal block can be the standard sync signal block, while in the second set the type 2 sync signal block can be the standard sync signal block. Table 2A and Table 2B illustrate the two different sync signal block schemes for different frequency bands.

[0083] The choices about the types of SSB for inclusion in the schemes in Table 2 and Table 3 are for example purposes only, and other scheme configurations are also covered. In addition, for the differentiation of frequency bands from the multiple types of synchronization signal blocks, it must be understood that the differentiation can occur in relation to more than two frequency bands and, therefore, more than two schemes.
[0084] In some examples of modalities and modes as in Figure 5F, the access node can provide for each sync signal block an indication of its type of sync signal block, and such indication can be detectable by a terminal without receiving wire. In other examples of modalities and modes, the access node may not provide explicit identification about the type of sync signal block, but may, however, interleave sync signal blocks of different types in a transmission to a wireless terminal. In this unidentified mode, the wireless terminal may initially assume that the received sync signal blocks belong to a first type or standard type of sync signal block, but upon encountering a sync signal block that does not decode according to the type of standard sync signal block, the wireless terminal may need to deduce or otherwise determine the content of the received non-standard sync signal block.
[0085] Figure 5F illustrates an exemplary access node 22F that can, according to different examples of modalities and modes,
Petition 870190068092, of 07/18/2019, p. 68/113
31/71 provide sync signal block type identification (SSB TYPE ID) in several ways. For example, the node processor of access node 22F may provide identification of the type of sync signal block using an index, or a combination of two or more indexes, which is / are mapped to the structure synchronization signal block. A sync signal block type index can be of several types: sync signal block index; burst rate of synchronization signal; sync signal burst set index. The concepts of sync signal block, sync signal block burst and sync signal block burst set are understood with reference to Figure 3, for example. Thus, the indication of a type of sync signal block can comprise one or more of a sync signal block index, a sync signal block burst index, and a signal block burst set index. synchronization.
[0086] In some examples of modalities and modes, an index can be obtained from a symbol, from a combination of symbols or from any other information or pattern of information transmitted in a frame. The index (or indexes) can be included in the synchronization signal block itself (as shown by way of example in Figure 10A) or transmitted elsewhere in the frame (as shown by way of example in Figure 10B). For example, the index (or indexes) can be transmitted in the tertiary sync signal (TSS) of a sync signal block that includes a tertiary sync signal (TSS).
[0087] In some examples of modalities and modes, an index can refer to a time and / or frequency locator of the frame. For example, the wireless terminal can identify the type of the sync signal block (for example, SSB TYPE ID) based on the
Petition 870190068092, of 07/18/2019, p. 69/113
32/71 index (for example, a time index and / or a frequency index) of the sync signal block, the index (indices) of the sync signal burst and / or the index of the set of burst bursts. synchronization. That is, the index (or indexes) of the sync signal block, the sync signal burst and / or the set of sync signal bursts can be used to indicate the type of sync signal block. See, for example, Figure 10C which shows how an index indicating the type of SSB can be related to frequency (frequency index). The frequency index is defined as the displacement of the first SSB subcarrier in the frequency domain to some common frequency reference point.
[0088] Regarding the above, for example, based on the index (indices) of the sync signal block, the sync signal burst and / or the set of sync signal bursts, the wireless terminal can determine (identify, recognize) one or more symbols and / or an interval index on a radio frame. For example, an index can be defined (for example, indicated, configured) for each sync signal block within a sync signal burst and / or a set of sync signal bursts. In addition, an index that is specific to each sync signal block can be defined within a sync burst and / or a set of sync burst. In addition, a burst burst index that is specific to each burst burst can be defined within a set of burst bursts. In addition, the burst burst index (s) and / or burst burst set may be common among the burst signal blocks in each burst burst and / or each burst set. synchronization.
Petition 870190068092, of 07/18/2019, p. 70/113
33/71 [0089] In addition, the index (indices) of the synchronization signal block can be indicated (identified, configured) using PSS, SSS, TSS and / or PBCH. For example, the index (indices) of the synchronization signal block can be implicitly and / or explicitly indicated using PBCH. In addition, the wireless terminal can assume that a sync signal block (e.g., a given sync signal block) is repeated with a burst burst periodicity. In addition, the wireless terminal can assume that a sync signal block (for example, a given sync signal block) is repeated with a set of sync signal burst intervals. Here, the burst frequency of the burst signal and / or the burst frequency of the burst burst can be predefined with a standard fixed value, or can be configured by the access node (for example, the base station device) .
[0090] As a first example of implementing a sync signal block type index indication, it will be assumed here that an SS block index (i.e., the SS block index) starts from zero ( 0). In such a case, an SS block index ”0 may indicate the first type of SS block structure (which may include a complete set of sync signal block information or the standard type of sync signal block discussed above) ); the SS block index ~ 1 may indicate a second type of SS block structure (which may include a subset of the information defined for the first type of SS block structure); the SS ™ 2 block index may indicate a third type of SS block structure (which may include another subset of the information defined for the first type of SS block structure); and so on. In this way, the access node in Figure 5F can generate and transmit a sync signal block index to indicate the type of
Petition 870190068092, of 07/18/2019, p. 71/113
34/71 sync signal block of a given sync signal block.
[0091] As a second example of implementing a sync signal block type index indication, access node 22F may provide an SS burst set index (i.e., the SS burst index and / or the SS burst set index) that indicates the type of SS block structure. When providing the SS burst set index for this second example implementation, all SS blocks in a given SS burst set share the same SS block structure. In other words, in this second example of implementation, an index of a higher hierarchical layer (set of bursts) may subsume or cover the bursts or blocks of synchronization signal included in the highest layer. Thus, according to this second example implementation, the access node can generate and transmit a burst burst index to indicate the type of burst signal block of multiple burst signal blocks belonging to a burst burst. of sync signal, or it can generate and transmit a sync signal burst set index to indicate the sync signal block type of multiple sync signal blocks belonging to a sync signal block burst set.
[0092] As a third example of implementing a sync signal block type index indication, an odd SS block index of the odd burst of SS burst indicates the first type of SS block structure, an odd SS block index from the even burst burst SS index indicates the second type of SS block structure, and so on. Thus, it may also be that the use of two or more of the values of the sync signal block index, the
Petition 870190068092, of 07/18/2019, p. 72/113
35/71 sync signal and sync signal block burst index serve as indexes for a mapping of two or more dimensions to a specific sync signal block type value for a specific sync signal block . For example, a combination of two or more from a sync signal block index, a sync signal block burst index, and a sync signal block burst index generated by the processor circuit can be used to indicate the type of sync signal block.
[0093] The exemplary access node 22F of Figure 5F can provide identification of the type of synchronization signal block (SSB TYPE ID) in yet other ways. For example, the access node may include an indication of the type of sync signal block in the SSB itself, for example, in a PBCH or in the primary or secondary sync signal.
[0094] In some examples of modalities and modes, the access node is configured to generate the synchronization signal block in a way in which its type of synchronization signal block is determinable from a transmission parameter. For example, in the example access node 22G of Figure 5G, the type of synchronization signal block is determined from a parameter known as the system frame number (SFN, for System Frame Number), for example, the SFN of a frame in which the sync signal block is included. Specifically, the type of sync signal block can be determined based on the frame identification number in the system (SFN). As known in the art, the access node generates frame identification numbers in the system (SFN), which are typically expressed in a finite number of bits, for example, ten bits. The finite number of bits means that the SFNs are reused after reaching the bad SFN
Petition 870190068092, of 07/18/2019, p. 73/113
36/71 maximum given by the finite number of bits. For example, if the SFN is ten bits long, then the SFNs are designated as 0 through 1023, and then repeated. Then, in the examples of modalities and modes such as those typified by Figure 5G that use SFN to identify the type of sync signal block, access node 22G is configured to associate a given type of sync signal block with one or more certain SFN values and include that given type of sync signal block in the frame (or frames) that has the associated SFN value. In this way, the 60G sync signal block generator generates a specific sync signal block for inclusion in a system frame that has a system frame identification number (SFN) that is associated with a type of signal block synchronization for that specific sync signal block.
[0095] In the example in Figure 5G, wireless terminal 26 gets an indication of the type of sync signal block for a specific sync signal block based on an SFN of a system frame in which the sync signal block. specific synchronization is transmitted. In particular, wireless terminal 26 obtains an indication of the type of sync signal block for a specific sync signal block based on an SFN of a system frame in which the specific sync signal block is transmitted. [0096] As an example of the aforementioned, wireless terminal 26 can identify different SS block structures through the system frame identification numbers (SFN), which can be obtained by decoding the PBCH, or at least partially from from the PBCH. For example, in a specific SFN, for example, SFN = 100, 220, 300 etc., the SS block structure with multiplexed data transmission is used.
[0097] Regarding the above, Figure 12 shows an example
Petition 870190068092, of 07/18/2019, p. 74/113
37/71 pio of scenario in which a first type of sync signal block (for example, the standard type of sync signal block) is associated with an SFN ™ 100, and a second type of sync signal block ( for example, the type of non-standard sync signal block) is associated with an SFN = 500. When wireless terminal 26 receives a sync signal block in a frame that has SFN = 100, wireless terminal 26 will know that the received sync signal block is of the first type of sync signal block. Alternatively, when wireless terminal 26 receives a sync signal block in a frame that has SFN = 500, wireless terminal 26 will know that the received sync signal block is of the second type of sync signal block.
[0098] Other SFN values can be associated with one or more types of synchronization signal blocks. In addition, a first type of synchronization signal block can be associated with several SFNs, for example, SFN = 100, SFN = 200, ..., SFN = 400, and likewise the second type of signal block of synchronization can be associated with multiple SFNs (eg SFN 500, SFN 600 etc.).
[0099] As a variation of Figure 5G, the access node 22G can use a combination of explicit identification by index and SFN value to identify the type of synchronization signal block. For example, for some predefined SFN (s), the SS X block index with SS Y burst index and SS Z burst index may indicate a specific type of SS block structure or type of sync signal block. For other predefined SFN (s), the SS X block index with SS Y burst index and SS Z burst index can indicate another specific type of SS block structure, for example, another type of sync signal block.
[00100] Various ways in which the access node can provide an indication of the type of signal signal block are described above
Petition 870190068092, of 07/18/2019, p. 75/113
38/71 timing for a specific sync signal block. Among the ways discussed above are the inclusion of one or more indices and the generation of the synchronization signal block in association with a transmission parameter such as the frame identification number in the system (SFN). In some examples of modalities and modes, the access node can be additionally configured to transmit disregard information of the type of synchronization signal block that prevails over the above indications (for example, index or SFN association) of the type of block of synchronization. synchronization signal provided by the network. For example, when wireless terminal 26 is in a Radio Resource Control (RRC) mode / state, the detected SS block structure (that is, the type of sync signal block) can be updated by dedicated RRC signaling, or transmission signaling, for example. Then, after the wireless terminal 26 receives the network update signal indicating its block structure, the indicated update structure disregards the assumption of the SS block structure wireless terminal mapped from index and / or information. of SFN. On the other hand, when wireless terminal 26 is in the idle state or when wireless terminal 26 is in idle mode, the detected SS block structure can be updated by transmitting signaling.
[00101] In examples of modalities and modes like many of those described above, wireless terminal 26 can be configured essentially to be pre-alerted or previously warned to expect different types of sync signal blocks, and in fact In many of these examples of modalities and modes the wireless access node can provide the terminal 26 with a mechanism for identifying the type of sync signal block of a received sync signal block. But in other examples of modali

39/71 activities and modes, as shown in Figure 5H, wireless terminal 26 can nominally or blindly assume that all incoming or received sync signal blocks must be of a specific sync signal block type (for example, example, the standard sync signal block type), in which case they may need to react to receiving a non-standard sync signal block. In Figure 5H, the terminal processor is shown comprising a sync signal block type detector with 70H candidate test field decoding. The synchronous signal block type detector with candidate 70H test field decoding has a list of candidate information elements for testing, the candidate could be the complete set or subset of information elements in the standard SSB. [00102] Thus, as indicated above, in some examples of modalities and modes, the access node may not provide explicit identification about the type of synchronization signal block, but may, however, interpose synchronization signal blocks of a different type when transmitting to a wireless terminal. In that unidentified mode, the wireless terminal may unlawfully assume that the received sync signal blocks belong to a first type or standard type of sync signal block. But when encountering a sync signal block that does not decode according to the standard sync signal block type, the field decode sync block type detector 70 of the wireless terminal in Figure 5H may need to deduce or otherwise determine the content of the received non-standard sync signal block. For example, the sync signal block type detector with candidate test field decoding 70H can initially process the received sync signal block as a standard sync signal block type, but upon finding
Petition 870190068092, of 07/18/2019, p. 77/113
40/71 a received sync signal block field that does not decode according to the standard sync signal block type, the sync signal block type detector with 70H candidate test field decoding can attempt to determine a type of information suitable for the field found.
[00103] If, for example, when entering a new cell (for example, for initial cell selection and / or for an idle wireless terminal), the wireless terminal receives (presupposes) a synchronization signal block which is of the standard sync signal block type, the sync signal block type detector with candidate 70H test field decoding of the wireless terminal 26 can determine the structure of the sync signal block to obtain or confirm the perception of what features of the sync signal block are assigned to the information transmitted by the primary sync signal block (for example, the standard sync signal block type). Based on the example and the orientation of such a first received sync signal block to be a standard sync signal block, the wireless terminal can intelligently attempt to similarly decode other sync signal blocks received through the air interface. In this way, the wireless terminal preliminarily assumes that it knows what type of information will be assigned to each partition or segment (for example, field) of the synchronization signal block, and consequently allocates a suitable detector / decoder for each segment or partition. But if the wireless terminal finds a field in the received sync signal block that does not decode with the type of decoder that the wireless terminal believed to be suitable for that field, for example, according to the CRC analysis (Cyclic Redundancy Check , or cyclic redundancy check) of PBCH decoding, the negative result will be shown in the field that is believed to be the PBCH,
Petition 870190068092, of 07/18/2019, p. 78/113
41/71 and then the wireless terminal will realize that the received sync signal block is a type of non-standard sync signal block. Upon realizing that the sync signal block is of a non-standard type, the sync signal block type detector with 70H candidate test field decoding can use a trial and error approach to decode the nonconforming field through confirmation with some criteria, for example, CRC analysis. For this purpose, wireless terminal 26 includes logic for sequentially implementing different decoders / detectors according to possible different types of sync signal block fields, for example types of sync signal block information, up to the wireless terminal succeed in decoding / detecting the non-compliant field.
[00104] On the other hand, if upon entering a new cell, the wireless terminal receives (presupposes) a sync signal block that is not of the primary sync signal block type (for example, the standard sync signal), the wireless terminal may allocate decoders of different types, by trial and error, in an attempt to deconstruct the received sync signal block. That is, the wireless terminal receives (presupposes) a sync signal block that is any type of non-standard sync signal block.
[00105] In some examples of modalities and modes, the sync signal block type detector with 70H candidate test field decoding can attempt to successfully decode / detect each field in a received sync signal block to consider the block synchronization signal as being fully processed. That is, the sync signal block type detector with 70H candidate test field decoding blindly decodes / detects the sync signal block fields until they are informed.
Petition 870190068092, of 07/18/2019, p. 79/113
42/71 correct information is obtained from each field of the sync signal block.
[00106] In other examples of modalities and modes, a partial (not complete) recovery of the sync signal block can be useful or advantageous, particularly if wireless terminal 26 is expecting a sync signal block to be of the standard type , but discover that the received sync signal block is not the standard type. In examples of modalities and modes in which the recovery of a sync signal block is partial, the information / fields included in a sync signal block can be divided into at least two classes or categories: (1) a first class, which can be, for example, essential sync signal information, and (2) a second class, which can be, for example, non-essential sync signal information. In examples of embodiments and modes in which the first class comprises essential timing information, such essential timing information may comprise, for example, any, or any combination of timing information elements that are generally included in blocks. standard sync signal, such as PSS / SSS. In examples of embodiments and modes in which the first class comprises non-essential sync signal information, such essential sync information may include fields from the sync signal block in addition to fields of the essential sync signal information. In the examples of modalities and modes in which the recovery of a sync signal block is partial, the sync signal block type detector with candidate test field decoding 70H can, upon finding a sync signal block type non-standard, perform modified search / decode logic.
Petition 870190068092, of 07/18/2019, p. 80/113
43/71 [00107] The modified search / decode logic can be advantageous to help save time and energy during SS block detection. For example, if in each SS block there is first class (for example, essential information) and second class (for example, non-essential information), blind decoding to retrieve fields from the block that do not conform to the standard type of sync signal block can take a very long time and consume considerable energy. In addition, SS block information can be repeated (as in LTE technology, PSS and / or SSS are repeated every 5 ms, while a PBCH is repeated every 40 ms). Therefore, if the wireless terminal can always obtain essential information from each SS block, then the need for wireless terminal 26 to obtain non-essential information from each SS block may not be a problem.
[00108] An example of modified search / decoding logic is to search for a single candidate in each field, for example, to search for a single candidate that the detector believes to be the most suitable in that field in the standard SSB. If such a search fails, the sync signal type detector with test field decoding candidate 70H will then obtain only the essential information from the sync signal block, and may later attempt to obtain information correct non-essentials from another SS block. Alternatively, as another example of modified search / decode logic, wireless terminal 26 may decide that after retrieving first class information (for example, essential SSB information), it may not be worth trying to retrieve second class information (for example, non-essential information) from that particular sync signal block, and thus save energy that would otherwise be spent on a trial and error search for
Petition 870190068092, of 07/18/2019, p. 81/113
44/71 candidates for the field that does not conform to the standard sync signal block type.
[00109] Thus, in an implementation example that employs modified search / decode logic, upon finding the received sync signal block field that does not decode according to the standard sync signal block type, the detector type of sync signal block with test field decoding 70H candidate will be able to test a candidate for the field and, if that candidate is not suitable for the field, use only sync signal information that would otherwise be recoverable from the non-standard sync signal block.
[00110] In an example of mode and mode, in processing a series of sync signal blocks, the wireless terminal can use a combination of sync signal block type index indication (to determine the type of block sync signal blocks of some of the series sync signal blocks) and the decoding of the wireless terminal itself to determine the types of sync signal block of other sync signal blocks in the series. For example, the sync signal block type detector 70 can start processing one or more sync signal blocks from a series of sync signal blocks using the sync signal block type indication provided by the sync node. access, but after that you can start using your sync signal block type detector with 70H candidate test field decoding, as described above.
Use of beam IP to determine sync signal block time index [00111] In another example of mode and mode, the sync signal blocks generated by access node 22 are based on
Petition 870190068092, of 07/18/2019, p. 82/113
45/71 bundles. Figure 13 shows a set of sync signal block bursts 80 comprising sync signal block bursts 82i and 822. Each sync signal block burst 82 comprises multiple sync signal blocks, each of which having a different sync signal block time index. Each sync signal block, and therefore each sync signal block time index associated with each respective sync signal block, is paired or associated with a single beam among the multiple beams transmitted by the access node. .
[00112] Figure 5! shows access node 22F comprising a system information generator (IS) 54 that generates an identity that expresses, for example, a beam ID (beam identifier, or BID). Figure 5I further shows that the terminal processor 40 of the wireless terminal 26I comprises a sync signal block type detector 88 which determines a sync signal block time index from the beam ID that is received from the access node 26I.
[00113] Figure 14 shows examples of basic steps or steps performed by wireless terminal 26I in Figure 5I. Step 14-1 comprises the wireless terminal receiving a beam identifier (BID) from the access node 22F via radio interface 24. The beam ID (BID) can be obtained in any of the ways described in the patent application US Provisional Order No. 62 / 453,986, filed on February 2, 2017, entitled SYNCHRONIZATION SIGNAL TRANSMISSION AND RECEPTION FOR RADIO SYSTEM ”, which is hereby incorporated by reference in its entirety. After wireless terminal 26I determines the Beam Identifier (BID) using techniques such as step 14-2, the sync signal block type detector 88 uses the beam identifier (BID) to determine a time index of
Petition 870190068092, of 07/18/2019, p. 83/113
46/71 sync signal block for a sync signal block that is associated with the beam identifier (BID). For example, the beam identifier (BID) can be matched to the sync signal block time index, or used mathematically to determine the sync signal block time index, or used as an index on a mapping table , or similar, to determine the sync signal block time index. Additionally, in optional step 14-3, processor 40 can use the sync signal block time index terminal to determine a sync signal block type for a received sync signal block.
[00114] There may be two alternative examples of modalities and modes for the SS block index. In a first example of modality and mode, the time index can be counted in a set of SS bursts (in this case, no SS burst concept is defined). In a second example of modality and mode, the time index can be counted within the burst of SS. As used here, the beam identifier (BID) can be according to any of these alternative examples of modalities and modes, for example, the assignment of beam ID (on the network side) is done by SS burst, or by set of bursts of SS.
[00115] 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 here can be included in the computer circuits of Figure 15. Figure 15 shows an example of such electronic machines or circuits, whether we are or terminals, comprising one or more processor circuits 90, program instruction memory 91, other memory 92 (for example
Petition 870190068092, of 07/18/2019, p. 84/113
47/71 pio, RAM memory, cache memory etc.), input / output interfaces 93, peripheral interfaces 94, support circuits 95 and buses 96 for communication between the above-mentioned units.
[00116] The program instruction memory 91 may comprise coded instructions that, when executed by one or more processors, perform steps that include, but are not limited to those described herein. Thus, it is understood that each of the node processor 30 and the terminal processor 40, for example, includes a memory in which non-temporary instructions are stored for execution.
[00117] With respect to the above, access node 22 of any of the examples of modalities and modes described herein can comprise at least one processor (for example, 30/90 processor), at least one memory (for example, memory 91) including computer program code, the memory and computer program code being configured to, operating with at least one processor, cause the access node to perform the steps described here, such as those shown in Figure 8, for example. Similarly, the wireless terminal 26 of any of the examples of modalities and methods described herein can include at least one processor (for example, 40/90 processor), at least one memory (for example, memory 91) including code computer program, the memory and the computer program code being configured to, operating with at least one processor, make the wireless terminal 26 perform the steps described here, such as those shown in Figure 9, for example.
[00118] The memory, or computer-readable media, can be one or more of a readily available memory, such as random access memory (RAM), read-only memory (ROM), floppy disk, hard disk, flash memory or any another form of air
Petition 870190068092, of 07/18/2019, p. 85/113
48/71 digital storage, local or remote, and is preferably non-volatile in nature. 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.
[00119] To summarize and explain the above, an SS block structure has been defined here: the SS block can comprise synchronization signals (NR-PSS and / or NR-SSS and / or a third synchronization signal (NR- TTS) indicating other information such as SS block index and / or some other type of SS), and / or NR-PBCH (one NR-PBCH, or two NR-PBCHs including a first physical transmission channel and a second physical channel transmission), and / or reference signals (for example, measurement reference signal (NR-IVIRS), and / or reference signals for PBCH decoding, and / or some other type of reference signal), and / or signaling transmitted by NR-PDCCH, and / or data by NR-PDSCH and / or PRACH.
[00120] Additionally, the SS block can have a fixed multiplexing structure for a given carrier frequency band. For different carrier frequency bands (an example is below 6 GHz and above 6 GHz). Certainly, there could be more than the two categories of carrier frequency band above; o one or more separation points to categorize different carrier frequency bands could also be other frequencies, the SS block can have a different fixed structure.
[00121] Furthermore, the fixed structure of the SS block means, for a given frequency band, that an SS block corresponds to N OFDM symbols based on the standard subcarrier spacing, and that N is a constant. In addition, the signal multiplexing structure (as mentioned above in relation to the SS block structure) is also fixed. In other words, the resources of time and
Petition 870190068092, of 07/18/2019, p. 86/113
49/71 frequency defined for an SS block, the fixed resources of time and frequency are allocated to the corresponding signals / channels / signaling / data.
[00122] There are two alternative fixed multiplexing designs for SS blocks, called Alt A and Alt B below.
[00123] For Alt A there are M types of SS block structures (where, M> 1) for a given carrier frequency band. Each type of SS block has the same fixed multiplexing structure.
[00124] Alt A.1: The UE identifies different SS block structures through an index, for example, SS block index and / or SS burst index and / or SS burst set index; in other words, any one, or any combination of two, or the combination of three types of index (SS block index, SS burst index, and SS burst set index) is mapped to a block structure of SS. The relationship could be any mapping from index X or combinations of indexes to M (where, X> 1). (At this point, a mapping figure could be included).
[00125] Example A. 1.1: The SS ™ block index 0 (if the SS block index starts from 0) indicates the first type of SS block structure (which may include the full set of defined information in paragraph 1); the SS ™ block index 1 indicates the second type of SS block structure (which may include a subset of the information defined for the first type of SS block structure. For example, the complete set of information consists of PSS / SSS, reference signals and PBCH; this type of SS block structure consists of PSS / SSS only); the SS block index 2 indicates the third type of SS block structure (which may include another subset of the information defined for the first type of SS block structure); and so on.
[00126] Example A. 1.2: Similarly, the pool index
Petition 870190068092, of 07/18/2019, p. 87/113
50/71 bursts of SS indicates the type of SS block structure. This means that all SS blocks in a specific SS burst set share the same SS block structure.
[00127] Example A. 1.3: The odd SS block index of the odd burst SS index indicates the first type of SS block structure. The odd SS block index of the SS burst set index indicates the second type of SS block structure. And so on.
[00128] Alt A.2: The UE identifies different SS block structures through the system frame identification number (SFN), which can be obtained by decoding the PBCH, or at least partially from the PBCH. For example, in some specific SFN, for example, SFN = 100, 200, 300 etc., the SS block structure with multiplexed data transmission is used. For the present disclosure, 100, 200, 300 ”were used as an example; those numbers could be any other SFN numbers.
[00129] Alt A.3: Any combination of Alt A.1 and Alt A.2. For example, in some predefined SFN (s), the SS X block index with SS Y burst index and SS Z burst index indicates a specific type of SS block structure.
[00130] Alt A.4: Information transmitted directly by the PBCH to indicate the SS block structure.
[00131] Alt A.5: Information transmitted directly by the SS to indicate the SS block structure.
[00132] From the point of view of the UE, this assumes a fixed mapping relationship defined in the alternatives of Alt A.1 to Alt A.3. After obtaining the index and / or SFN information, the UE knows the structure of the SS block. Or the UE obtains SS block structure information from the decoded PBCH information or the detected SS information, as described in Alt A.4 and Alt A.5.
Petition 870190068092, of 07/18/2019, p. 88/113
51/71 [00133] For the SS block structure without a complete set of information (some information is ignored in the fixed multiplexing structure), there are two alternative designs, that is, Alt A.X and Alt A.Y.
[00134] Alt A.X: The resources used by the signal / channel / signaling / data ignored in an SS block are kept there without any other use. Thus, the UE does not receive useful information from reserved resources (reserved resources are filled with all 0 or all 1).
[00135] Alt AY: As indicated in SLA 3707P, the resources used by the signal / channel / signaling / data ignored in an SS block are used by other signals / channels / signaling / data, for example, in the repetition format of others signals / channels / signaling / data; or in the format to always be used by a PDCCH and / or a PDSCH and / or a PRACH. The UE assumes a fixed predefined resource reuse format of the resources, as indicated in this paragraph, for each type of SS block structure. In this way, the UE can obtain other information from that SS block.
[00136] In the case of Alt A.Y, when the UE is in radio resource connection (RRC) mode / state, the detected SS block structure can be updated by dedicated RRC signaling, or transmission signaling; for example, after the UE receives a signal from the network indicating its block structure, the indicated structure disregards the assumption of the SS block structure UE mapped from index and / or SFN information; on the other hand, when the UE is in an idle state or when the UE is in idle mode, the detected SS block structure can also be updated by transmission signaling.
[00137] Alt B: All SS blocks have the same fixed multiplexing structure for a given carrier frequency band. In this alternative, some information, which could be any
Petition 870190068092, of 07/18/2019, p. 89/113
52/71 one or more of the signal / channels / signaling / data defined in the first paragraph, can be ignored in some SS blocks. However, the UE does not know what information is ignored. The UE always assumes the only fixed multiplexing structure for the SS block. For the SS block structure without a complete set of information (some information is ignored in the fixed multiplexing structure), the two alternative designs Alt AX and Alt AY are also applicable to Alt B. The UE blindly detects the block structure of SS. In this design, the UE assumes the periodicity of each signal / channel / signaling / data in the SS block, for example, the SS has a 5 ms periodicity; the PBCH has a 40 ms periodicity; the signaling is allowed to be transmitted in every 5 blocks of SS; and the data is allowed to be transmitted in every 10 SS blocks; so, after the UE successfully detects some information in an SS block, it knows in which SS blocks it detects the corresponding information again (in other words, this means that the UE assumes different detection windows including different number SS blocks to detect different signal / channel / signaling / data). Of course, the periodicity mentioned in the example could be any other values, and the information to build the SS block could also be any one in paragraph 1. If the Alt AX alternative is adopted, the complexity of blind detection is less, since that it is easy for the UE to detect the reserved bits (the values of the reserved bits are known to the UE, for example, all 0 or all 1).
[00138] Similar to the Alt A alternative, the SS structure information can be updated by signaling the network, according to the state of the UE.
[00139] In addition, the alternative Alt B can also be combined with Alt A. For example, the UE can detect the SS block structure
Petition 870190068092, of 07/18/2019, p. 90/113
53/71 with the method indicated in Alt A, for example, through the SS block index information; then, the UE can use Alt B to continue detecting signal / channel / signaling / data information in the next SS block, for example, assuming signal / channel / signaling / data periodicity information.
[00140] Thus, the technology disclosed here comprises and encompasses the following non-exhaustive examples of modalities and modes:
[00141] Example of Mode 1: An access node comprising:
