SIGNALING OF BEAM FORMATION RELATIONSHIPS BETWEEN DATA AND CONTROL CHANNELS
CROSS REFERENCE TO RELATED APPLICATION & PRIORITY CLAIM [0001] This application claims priority for Order No. US 15 / 713,074, filed on September 22, 2017, which claims benefit from and priority for Serial Patent Application US 62 / 420,036, filed on November 10, 2016, which are incorporated by reference in their entirety for all purposes applicable in this document.
TECHNICAL FIELD [0002] Aspects of the present disclosure relate to wireless communications and, more particularly, signaling information relating to the beams used for control and data transmissions.
INTRODUCTION [0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcasts. Typical wireless communication systems can employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth, transmission power). Examples of such multiple access technologies include Long Term Evolution (LTE) systems,
access multiple per division in code (CDMA), systems in access multiple per division in time (TDMA), systems in access multiple per division in frequency (FDMA), systems
Petition 870190042984, of 7/7/2019, p. 7/76
2 / 5Q orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access systems (SC-FDMA) and time division synchronous code division multiple access systems (TD-SCDMA) .
[0004] In some examples, a wireless multiple access communication system may include several base stations, each simultaneously supporting communication to multiple communication devices, otherwise known as user equipment (UEs). In the LTE or LTE-A network, a set of one or more base stations can define an eNodeB (eNB). In other examples (for example, on a 5G or next generation network), a wireless multiple access communication system may include multiple distributed units (DUs) (for example, edge units (EUs), edge nodes (ENs) ), radio heads (RHs), intelligent radio heads (SRHs), transmit reception points (TRPs), etc.) in communication with several central units (CUs) (for example, central nodes (CNs), controllers of access node (ANCs, etc.), where a set of one or more units distributed in communication with a central unit can define an access node (for example, a new radio base station (BS of NR), a new radio B node (NB of NR), a network node, 5G NB, gNB, etc.). A base station or DU can communicate with a set of UEs on downlink channels (for example, for transmissions from a base station or for a UE) and uplink channels (for example, for transmissions from UE to a base station or distributed unit).
Petition 870190042984, of 7/7/2019, p. 8/76
3/50 [0005] These multiple access technologies have been adopted in several telecommunication standards to provide a common protocol that allows different wireless devices to communicate at a municipal, national, regional and even global level. An example of an emerging telecommunication standard is the new radio (NR), for example, 5G radio access. It is designed to better support mobile broadband Internet access by improving spectral efficiency, by reducing costs, by improving services, by using new spectrum and by better integration with other open standards with the use of OFDMA with a prefix cyclical (CP) on the downlink (DL) and on the uplink (UL) as well as support beam formation, multiple input and multiple output antenna (MIMO) technology and carrier aggregation.
[0006] However, as the demand for mobile broadband access continues to increase, there remains a need for further improvements in NR technology. Preferably, these enhancements should apply to other multiple access technologies and the telecommunication standards that employ those technologies.

8/50 aim at critical mission targeting. These services may include reliability and latency requirements. These services may also have different transmission time intervals (TTI), where a TTI can refer to a subframe or portion of a subframe (for example, a time partition) to satisfy the respective quality of service requirements (QoS) . In addition, these services can coexist in the same subframe.

The word exemplary is used in this document to mean that it serves as an example, case or illustration. Any aspect described in this document as an example should not necessarily be interpreted as preferential or advantageous over other aspects.
[0029] The techniques described in this document can be used for various wireless communication networks such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms network and system are often used interchangeably. A CDMA network can deploy radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Broadband CDMA (WCDMA) and other CDMA variants. Cdma2000 covers the IS-2000, IS-95 and IS856 version standards. A TDMA network can deploy radio technology like the Global System for Mobile Communications (GSM). An OFDMA network can deploy radio technology such as NR (for example, RA 5G), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, OFDMA Flash, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunication System (UMTS). NR is an emerging wireless communications technology under development in conjunction with the 5G Technology Forum (5GTF). 3 GPP Long Term Evolution (LTE) and Advanced LTE (LTE-A) are versions of UMTS that use EUTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called the 3rd Generation Partnership Project (3GPP). Cdma2000 and UMB are described in documents from an organization called
Petition 870190042984, of 7/7/2019, p. 15/76
10/50
Partnership Project 3 Generation 2 (3GPP2). The techniques described in this document can be used for the wireless radio technologies and network mentioned above as well as other wireless radio technologies and networks. For the sake of clarity, while aspects may be described in this document using terminology commonly associated with 3G and / or 4G wireless technologies, aspects of the present disclosure may be applied to other generation-based communication systems, such as 5G and later, including NR technologies.
EXEMPLIFICATIVE WIRELESS COMMUNICATION SYSTEM [0030] Figure 1 illustrates an exemplary wireless network in which aspects of the present disclosure can be realized. For example, the wireless network can be a new radio (NR) or 5G network. Wireless NR communication systems can employ beams, in which a BS and UE communicate via active beams. As described in this document, a BS can monitor the active beams using measurements of reference signals (for example, MRS, CSI-RS, synchronization) transmitted through reference beams.
[0031] UEs 120 can be configured to perform operations 1000 and methods described in this document to detect mobility events based, at least in part, on mobility parameters associated with a beam set. BS 110 can comprise a transmit and receive point (TRP), Node B (NB), NB 5G, access point (AP), new radio BS (NR), etc.). BS 110 can be configured to perform 900 operations and methods described in this document for configuring sets
Petition 870190042984, of 7/7/2019, p. 16/76
11/50 beam and mobility parameters associated with each of the beam sets. The BS can receive an indication of a detected mobility event based on the mobility parameters and can make a decision regarding the mobility management of the UE based on the event trigger.
[0032] As shown in Figure 1, wireless network 100 can include several BSs 110 and other network entities. A BS can be a station that communicates with UEs. Each BS 110 can provide communication coverage for a particular geographic area. In 3GPP, the term cell can refer to a coverage area of a Node B and / or a subsystem of Node B that serves that coverage area, depending on the context in which the term is used. In NR systems, the term cell and gNB, Node B, 5G NB, AP, BS of NR, BS of NR or TRP can be interchangeable. In some instances, a cell may not necessarily be stationary, and the cell's geographical area may move according to the location of a mobile base station. In some examples, base stations can be interconnected with each other and / or with one or more other base stations or network nodes (not shown) on wireless network 100 through various types of feedback interfaces as a direct physical connection , a virtual network or the like using any suitable transport network.
[0033] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular radio access technology (RAT) and can operate on one or more
Petition 870190042984, of 7/7/2019, p. 17/76
12/50 frequencies. A RAT can also be called a radio technology, an aerial interface, etc. A frequency can also be called a carrier, a frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks from different RATs. In some cases, NR or RAT 5G networks can be deployed.
[0034] A BS can provide communication coverage for a macrocell, a picocell, a femtocell and / or other types of cell. A macrocell can cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographical area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively small geographic area (for example, a residence) and may allow restricted access by the UEs that are associated with the femtocell (for example, UEs in a Closed Subscriber Group (CSG), the UEs for users in the residence, etc.) . A BS for a macrocell can be called a macro-BS. A BS for a picocell can be called a pico-BS. A BS for a femtocell can be called a femto-BS or a domestic BS. In the example shown in Figure 1, BSs 110a, 110b and 110c can be macro-BSs for macrocells 102a, 102b and 102c respectively. BS HOx can be a pico-BS for a 102x picocell. BSs HOy and IlOz can be a femto-BS
Petition 870190042984, of 7/7/2019, p. 18/76
13/50 for femtocells 102y and 102z respectively. A BS can support one or multiple cells (for example, three).
[0035] Wireless network 100 may also include relay stations. A relay station is a station that receives a transmission of data and / or other information from an upstream station (for example, a BS or a UE) and sends a transmission of the data and / or other information to a downstream station ( for example, a UE or a BS). A relay station can also be a UE that relays transmissions to other UEs. In the example shown in Figure 1, an HOr relay station can communicate with BS 110a and UE 120r in order to facilitate communication between BS 110a and UE 120r. A relay station can also be called a relay BS, a relay, etc.
[0036] Wireless network 100 can be a heterogeneous network that includes BSs of different types, for example, macro-BS, pico-BS, femto-BS, relays, etc. These different types of BSs can have different transmit power levels, different coverage areas and different impacts on interference on the wireless network 100. For example, the macro-BS can have a high transmit power level (for example, from 20 Watts) while pico-BS, femto-BS and retransmitters may have a lower transmission power level (for example, 1 Watt).
[0037] Wireless network 100 can support synchronous or asynchronous operation. For synchronous operation, BSs can have similar frame timing, and transmissions from different BSs can be aligned
Petition 870190042984, of 7/7/2019, p. 19/76
Approximately 14/50 in time. For asynchronous operation, BSs can have different frame timing, and transmissions from different BSs cannot be time aligned. The techniques described in this document can

communicate with BSs 110 through a return. BS 110 can also communicate with each other, for example, directly or indirectly via wireless or wired feedback.
[0039] UEs 120 (e.g. 120x, 120y, etc.) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be called a mobile station, a terminal, an access terminal, a subscriber unit, a station, an Equipment on the Client's premises, a cell phone, a smartphone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a laptop computer, a cordless phone, a wireless local loop station (WLL), a tablet computer, a camera, a gaming device , a netbook-type computer, a smartbook-type computer, an ultrabook-type computer, a medical device or medical equipment, a biometric device / sensor, a wearable device, such as a smart watch, smart clothing, smart glasses, the band smart wrist, smart jewelry (for example, a smart ring, a
Petition 870190042984, of 7/7/2019, p. 20/76
15/50 smart bracelet, etc.), an entertainment device (for example, a music device, a video device, a satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing, a global positioning system device, or any other suitable device that is configured to communicate wirelessly or wired. Some UEs can be considered evolved or machine-type (MTC) communication devices or evolved MTC (eMTC) devices. The MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, devices, monitors, location indicators, etc., which can communicate with a BS, with another device (for example, remote device) or with any other entity. A wireless node can provide, for example, connectivity to or to a network (for example, a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered as Internet of Things (loT) devices.
[0040] In Figure 1, a solid line with double arrows indicates desired transmissions between a UE and a service BS, which is a BS designed to serve the UE on the downlink and / or the uplink. A dashed line with double arrows indicates interference transmissions between a UE and a BS.
[0041] Certain wireless networks (for example, LTE) use orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the link
Petition 870190042984, of 7/7/2019, p. 21/76
Ascending 16/50. OFDM and SC-FDM partition the system bandwidth into multiple orthogonal subcarriers (K), which are also called tones, boxes, etc. Each subcarrier can be modulated with data. In general, the modulation symbols are sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can be dependent on the system bandwidth. For example, the spacing of the subcarriers can be 15 kHz and the minimum resource allocation (called a 'resource block') can be 12 subcarriers (or 180 kHz). Consequently, the nominal FFT size can be 128, 256, 512, 1024 or 2048 for the system bandwidth of 1.25, 2.5, 5, 10 or 20 megahertz (MHz) respectively. The system bandwidth can also be partitioned into sub-bands. For example, a subband can cover 1.08 MHz (ie, 6 resource blocks), and there may be 1, 2, 4, 8, or 16 subbands for the 1.25 system bandwidth , 2.5, 5, 10 or 20 MHz respectively.
[0042] Although the aspects of the examples described in this document may be associated with LTE technologies, aspects of the present disclosure may apply to other wireless communications systems such as NR.
[0043] The NR can use OFDM with a CP on the uplink and downlink and include support for half duplex operation with the use of TDD. A single 100 MHz single component carrier bandwidth can be supported. NR resource blocks can
Petition 870190042984, of 7/7/2019, p. 22/76
17/50 cover 12 subcarriers with a 75 kHz subcarrier bandwidth over a duration of 0.1 ms. Each radio frame can consist of 50 subframes with a length of 10 ms. Consequently, each subframe can be 0.2 ms long. Each subframe can indicate a link direction (ie DL or UL) for data transmission and the link direction for each subframe can be switched dynamically. Each subframe can include DL / UL data as well as DL / UL control data. The subframes UL and DL for NR can be described in more detail below in relation to Figures 6 and 7. The beam formation can be supported and the beam direction can be dynamically configured. MIMO transmissions with pre-coding can be supported as well. The MIMO configurations on the DL can support up to 8 transmission antennas with multi-layered DL transmissions of up to 8 streams and up to 2 streams per UE. Multi-layer transmissions with up to 2 streams per UE can be supported. Multiple cell aggregation can be supported with up to 8 service cells. Alternatively, NR can support a different interface area, different from one based on OFDM. NR networks can include entities such as CUs and / or DUs.
[0044] In some examples, access to the interface air can be programmed, in which a programming entity (for example, a base station) allocates resources for communication between some or all devices and equipment within its area or service cell. Within the present disclosure, as discussed below, the programming entity may be responsible for
Petition 870190042984, of 7/7/2019, p. 23/76
18/50 program, assign, reconfigure and release resources for one or more subordinate entities. That is, for programmed communication, subordinate entities use resources allocated by the programming entity. Base stations are not just entities that can function as a programming entity. That is, in some examples, a UE can function as a programming entity, programming resources for one or more subordinate entities (for example, one or more other UEs). In this example, the UE can function as a programming entity, and other UEs use resources programmed by the UE for wireless communication. A UE can function as a programming entity in a point-to-point (P2P) network, and / or in a mesh network. In an exemplary mesh network, UEs can optionally communicate directly with each other in addition to communicating with a programming entity.
[0045] Thus, in a wireless communication network with programmed access to time and frequency resources and which has a cellular configuration, a P2P configuration, and a mesh configuration, a programming entity and one or more subordinate entities can communicate using programmed resources.
[0046] As noted above, a RAN can include a CU and DUs. An NR BS (for example, gNB, Node B 5G, Node B, transmit and receive point (TRP), access point (AP)) can correspond to one or multiple BSs. NR cells can be configured as an access cell (ACells) or data-only cells (DCells). Per
Petition 870190042984, of 7/7/2019, p. 24/76
19/50 example, the RAN (for example, a central unit or distributed unit) can configure the cells. DCells can be cells used for carrier aggregation or dual connectivity, but not used for initial access, cell selection / reselection or transfer. In some cases, DCells cannot transmit synchronization signals - in some cases, DCells can transmit SS. NR BSs can transmit downlink signals to UEs that indicate the cell type. Based on the cell type indication, the UE can communicate with the BS of NR. For example, the UE can determine the BSs of NR to consider cell selection, access, transfer and / or measurement based on the indicated cell type.
[0047] Figure 2 illustrates an exemplary logical architecture of a distributed radio access network (RAN) 200, which can be deployed in the wireless communication system illustrated in Figure 1. A 5G 206 access node can include a controller access node (ANC) 202. The ANC can be a central unit (CU) of the distributed RAN 200. The return interface to the next generation central network (NG-CN) 204 can end at the ANC. The return interface for nodes next to the next generation (NG-ANs) may end at the ANC. The ANC may include one or more 208 TRPs (which may also be called BSs, BSs of NR, BS of Node, NBs 5G, APs or some other terms). As described above, a TRP can be used interchangeably with the cell.
[0048] TRPs 208 can be a DU. TRPs can be connected to one ANC (ANC 202) or to more than one ANC (not shown). For example, for RAN sharing,
Petition 870190042984, of 7/7/2019, p. 25/76
20/50 radio as a service (RaaS), and specific service and deployments, the TRP can be connected to more than one ANC. A TRP can include one or more antenna ports. TRPs can be configured to serve individually (for example, dynamic selection) or together (for example, joint transmission) traffic to a UE.
[0049] Local architecture 200 can be used to illustrate the definition of advance. The architecture can be defined to support advance solutions through different types of deployment. For example, the architecture may be based on the transmission network capabilities (for example, bandwidth, latency and / or instability).
[0050] The architecture can share resources and / or components with LTE. According to the aspects, the next generation AN (NG-AN) 210 can support
dual connectivity with NR. 0 NA of NG can to share one common advance for LTE and NR. [0051] The architecture can enable The cooperation between and among the TRPs 208. For example, The
cooperation may be present within a TRP and / or through TRPs through ANC 202. According to the aspects, no inter-TRP interface may be required / present.
[0052] According to the aspects, a dynamic configuration of logical functions divided within the 200 architecture. As will be described in more detail with reference to Figure 5, the Radio Resource Control layer (RRC), the Protocol layer of Packet Data Convergence (PDCP), the Data Link Control layer

Radio (RLC), the Medium Access Control layer (MAC) and physical layers (PHY) can be placed adaptively in the DU or CU (for example, TRP or ANC, respectively). According to certain aspects, a BS can include a central unit (CU) (for example, ANC 202) and / or one or more distributed units (for example, one or more TRPs 208).
[0053] Figure 3 illustrates an exemplary physical architecture of a RAN distributed 300 according to the aspects of the present disclosure. A centralized central network unit (C-CU) 302 can host central network functions. C-CU can be implanted centrally. C-CU functionality can be downloaded (for example, for advanced wireless services (AWS)) in an effort to handle peak capacity.
[0054] A centralized RAN unit (C-RU) 304 can host one or more ANC functions. Optionally, the C-RU can host central network functions locally. The C-RU may have a distributed deployment. The C-RU may be closer to the network edge.
[0055] A DU 306 can host one or more TRPs (edge node (EN), edge unit (EU), radio head (RH), smart radio head (SRH) or similar). DU can be located at the edges of the network with radio frequency.
[0056] Figure 4 illustrates exemplary components of BS 110 and EU 120 illustrated in Figure 1, which can be used to implement aspects of the present disclosure. BS can include a TRP. One or more components of BS 110 and UE 120 can be used to practice aspects of the present disclosure. For example, the 452, Tx / Rx antennas

[0057] Figure 4 shows a block diagram of a BS 110 and UE 120 project, which can be one of the BSs and one of the UEs in Figure 1. For a restricted association scenario, base station 110 can be the macro-BS 110c in Figure 1, and the UE 120 can be the UE 120y. Base station 110 can also be a base station of some other type. Base station 110 can be equipped with antennas 434a to 434t, and UE 120 can be equipped with antennas 452a to 452r.

Each modulator 432 can process a respective output symbol stream (for example, for OFDM, etc.) to obtain an output sample stream. Each modulator 432 can further process (for example, convert to analog, amplify, filter and upwardly convert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 432a to 432t can be transmitted through antennas 434a to 434t respectively.
[0059] At UE 120, antennas 452a to 452r can receive downlink signals from base station 110 and can provide received signals to demodulators (DEMODs) 454a to 454r respectively. Each demodulator 454 can condition (for example, filter, amplify, downwardly convert and digitize) a respective received signal to obtain input samples. Each demodulator 454 can further process the input samples (for example, for OFDM, etc.) to obtain received symbols. A MIMO 456 detector can obtain symbols received from all demodulators 454a through 454r, perform MIMO detection on received symbols if applicable, and provide detected symbols.

[0060] On the uplink, on UE 120, a transmission processor 464 can receive and process data (for example, for the Physical Uplink Shared Channel (PUSCH)) from a data source 462 and control the information ( for example, for the Physical Uplink Channel (PUCCH) from controller / processor 480. The 464 transmission processor can also generate reference symbols for a reference signal. The 464 transmission processor symbols can be pre-encoded by a TX processor of MIMO 466 if applicable, further processed by demodulators 454a to 454r (for example, for SC-FDM, etc.), and transmitted to base station 110. In BS 110, the uplink signals of the UE 120 can be received by antennas 434, processed by modulators 432, detected by a MIMO detector 436 if applicable, and further processed by a receiving processor 438 to obtain control information le and decoded data sent by UE 120. Receiving processor 438 can provide decoded data to a data collector 439 and decoded control information to controller / processor 440.
[0061] The controllers / processors 440 and 480 can direct the operation on base station 110 and UE 120 respectively. The 440 processor and / or other processors and modules in the base station 110 can perform or direct, for example, the execution of the blocks

[0062] Figure 5 illustrates a diagram 500 showing examples for deploying a wireless communications stack according to aspects of the present disclosure. The illustrated wireless communications stacks can be deployed by devices that operate on a 5G system. Diagram 500 illustrates a wireless communications stack including a Radio Resource Control (RRC) layer 510, a Packet Data Convergence Protocol (PDCP) layer 515, a Radio Link Control (RLC) layer 520, a Medium Access Control (MAC) layer 525 a Physical (PHY) layer 530. In several examples, layers of a protocol stack can be deployed as separate software modules, portions of a processor or ASIC, portions of non-placed devices connected by a communications link or various combinations thereof.

[0063] A first option 505-a shows a split deployment of a protocol stack, in which the deployment of the protocol stack is split between a centralized network access device (for example, an ANC 202 in Figure 2) and a distributed network access device (for example, DU 208 in Figure 2). In the first option 505-a, a layer of RRC 510 and a layer of PDCP 515 can be implanted by the central unit, and a layer of RLC 520, a layer of MAC 525 and a layer PHY 530 can be implanted by the DU. In several examples, CU and DU can be placed or not placed. The first option 505a can be useful in a macrocell, microcell or picocell implantation.
[0064] A second option 505-b shows a unified deployment of a protocol stack, in which the protocol stack is deployed on a single network access device (for example, access node (AN), base station of new radio (BS of NR), a new Radio Node B (NB of NR), a network node (NN) or similar). In the second option, the RRC 510 layer, the PDCP 515 layer, the RLC 520 layer, the MAC 525 layer and the PHY 530 layer can each be implanted by the AN. The second option 505-b can be useful in a femtocell implantation.
[0065] Regardless of whether a network access device deploys part or all of the protocol stack, a UE can deploy an entire protocol stack (for example, the RRC 510 layer, the PDCP 515 layer, the RLC layer 520, the MAC 525 layer and the PHY 530 layer).

The control portion 602 may exist at the beginning or beginning portion of the DL centered subframe. Control portion 602 may include various programming information and / or control information corresponding to various portions of the DL-centered subframe. In some configurations, the control portion 602 can be a physical DL control channel (PDCCH) as shown in Figure 6. The DL centered subframe can also include a DL 604 data portion. The DL 604 data portion it can sometimes be called the payload of the DL-centered subframe. The DL 604 data portion may include the communication resources used to communicate the DL data from the programming entity (for example, UE or BS) to the subordinate entity (for example, UE).

The common UL portion 606 may include additional or alternative information, such as information pertinent to random access channel (RACH) procedures, programming requests (SRs) and various other suitable types of information. As shown in Figure 6, the end of the DL 604 data portion can be separated in time from the beginning of the common UL 60 portion 6. This time separation can sometimes be called an interval, a protection period, an interval protection and / or various other suitable terms. This separation provides time for the transition from DL communication (for example, receiving operation by the subordinate entity (for example, UE)) to UL communication (for example, transmission by the subordinate entity (for example, UE)). One of those skilled in the art will understand that the above is merely an example of a subframe centered on DL and alternative structures that have similar resources may exist without deviating necessarily from the aspects described in this document.

UL. The UL portion can refer to the communication resources used to communicate UL data from the subordinate entity (for example, UE) to the programming entity (for example, UE or BS). In some configurations, the control portion 702 can be a physical DL control channel (PDCCH).
[0069] As shown in Figure 7, the end of the control portion 702 can be separated in time from the beginning of the UL 704 data portion. This time separation can sometimes be called an interval, protection period, interval of protection and / or various other suitable terms. This separation provides time for the transition from DL communication (for example, receiving operation by the programming entity) to UL communication (for example, transmission by the programming entity). The UL-centered subframe can also include a portion of common UL 706. The portion of common UL 706 in Figure 7 may be similar to the portion of common UL 606 described above with reference to Figure 6. The portion of common UL 706 may include information additional or pertinent alternatives to the channel quality indicator (CQI), resonance reference signals (SRSs) and various other suitable types of information. One of those skilled in the art will understand that the above is merely an example of a sub-framework centered on UL and alternative structures that have similar resources can exist without deviating necessarily from the aspects described in this document.
[0070] In some circumstances, two or more subordinate entities (for example, UEs) may be

Real-world applications for such side-link communications may include public security, proximity services, network retransmission to the EU, vehicle-to-vehicle (V2V) communications, Internet of Everything (loE) communications, loT communications, network critical mission targeting and / or various other suitable applications. In general, a side link signal can refer to a signal communicated from a subordinate entity (eg UE1) to another subordinate entity (eg UE2) without relaying that communication through the programming entity (eg , UE or BS), although the programming entity can be used for programming and / or control purposes. In some instances, side link signals can be communicated
with the use of a spectrum licensed (unlike networks of local area without thread, what use typically a spectrum not licensed). [0071]a HUH can operate on multiple settings in resource radio, including a
configuration associated with transmission pilots using a dedicated resource set (for example, a dedicated radio resource control state (RRC), etc.) or a configuration associated with transmission pilots using a set of common resources (for example, a common RRC status, etc.). When operating in the dedicated state of RRC, the UE can select a set of dedicated resources to transmit a pilot signal to a network. When operating in the common state of RRC, the UE can select a common set of resources to transmit a pilot signal to the network.

In another case, a pilot signal transmitted by the UE can be received by one or more network access devices, such as an AN or DU or portions thereof. Each receiving network access device can be configured to receive and measure pilot signals transmitted in the common resource set, and also receive and measure pilot signals transmitted in the dedicated resource sets allocated to the UEs from which the network access device is a member of a set of monitoring network access devices for the UE. One or more of the receiving network access devices, or a CU to which the receiving network access device (or devices) transmits the measurements of the pilot signals, can use the measurements to identify service cells to the UEs or to initiate a service cell change for one or more of the UEs.
WAVE SYSTEMS mm [0072] As used in this document, the term Wave mm refers, in general, to spectrum bands above 6GHz at very high frequencies, for example, 28 GHz. Such frequencies can provide very wide bandwidths large ones capable of delivering multiple Gbps data rates, as well as the opportunity for extremely dense spatial reuse to increase capacity. Traditionally, these higher frequencies have not been robust enough for indoor / outdoor mobile broadband applications due to the high loss of propagation and susceptibility to blocking (for example, buildings, humans and the like).
Petition 870190042984, of 7/7/2019, p. 37/76
32/50 [0073] Despite these challenges, at the higher frequencies at which the Onda mm operates, the short wavelengths make it possible to use a large number of antenna elements in a relatively small suit. This feature of Wave mm can be leveraged to form narrow directional beams that can send and receive more energy, which can help to overcome the propagation / trajectory challenges.
[0074] These narrow directional beams can also be used for spatial reuse. This is one of the key enablers for using Onda mm for mobile broadband services. In addition, trajectories without line of sight (NLOS) (for example, reflections from nearby buildings) can have very large energies, providing alternative trajectories when line of sight (LOS) trajectories are blocked. Aspects of the present disclosure can take advantage of such directional bundles, for example, by using bundle bundles for managing beam and cell mobility.
[0075] Figure 8 illustrates an example of active beams 800 according to the aspects of the present disclosure. A BS and UE can communicate using a set of active beams. Active beams can refer to BS and UE beam pairs that are used to transmit data and control channels. A data beam can be used to transmit data and a control beam can be used to transmit control information. As shown in Figure 8, the BS-A1 data beam can be used to transmit DL data and the BS-A2 control beam can be used to transmit data from
Petition 870190042984, of 7/7/2019, p. 38/76
33/50 DL control. A control beam, which can serve more than one UE, can be wider than a data beam. An UE-A1 control / data beam can be used to transmit both UL control and UL data. As illustrated, UL data and control are transmitted using the same beam; however, control and data information can be transmitted using different beams. Similarly, data and control can be transmitted by the BS using different beams or the same beam.
[0076] In wireless communication systems that employ beams, such as mm wave systems, the high loss of trajectory presents a challenge. Accordingly, techniques that include hybrid beam formation (analog and digital), which are not present in 3G and 4G systems, can be used in such wireless systems. The hybrid beam formation creates narrow beam patterns for users (for example, UEs), which can improve the link / SNR budget. As described above, a BS and UE can communicate over active beams. Active bundles can be called service bundles. Active beams can include BS and UE beam pairs that carry data and control channels such as PDSCH, PDCCH, PUSCH, PUCCH, synchronization signals (SS), channel status information reference signals (CSI-RS) , RS resonance (SRS), RS phase tracking (PTRS), RS time tracking (TRS).
[0077] A BS can monitor beams using measurements and beam feedback from a UE. For example, a BS can monitor active beams using
Petition 870190042984, of 7/7/2019, p. 39/76
34/50 of DL reference signals. A BS can transmit an RS from DL, as a measurement reference signal (MRS), channel status information reference signal (CSI-RS), a synchronization signal (sync). A UE can report, to the BS, a reference signal receiving power (RSRP) associated with a received reference signal. In this way, the BS can monitor active beams.
[0078] The active beam sets may have different functionalities, characteristics and requirements. Otherwise, stated, the functionalities of one or more active bundles may differ from the functionalities of other active bundles. For example, a first set of active beams may include the control beam and a second set of active beams may include data transmissions. As another example, beams in a first set of active beams can be transmitted in a first direction and beams in a second set of active beams can be transmitted in a second direction, different from the first direction. During multi-link communication, a UE can be connected simultaneously to a first BS in the first direction and a second BS in the second direction. The beam shapes for each set of active beams may vary. For example, as described above, the control beam format of a BS may differ from a data beam format of the same base station.
EXAMPLIFICATIVE SIGNALING BEAM TRAINING RELATIONS BETWEEN CONTROL AND DATA CHANNELS [0079] In wireless communications, knowledge of various factors can help
Petition 870190042984, of 7/7/2019, p. 40/76
35/50 data transmissions and processing control. For example, in NR, the channel estimate for data demodulation (for example, PDSCH) can be improved by estimating various channel parameters, such as delay spread, Doppler, frequency error, time deviation and the like. If an indication is given that the data and control transmissions are likely to have similar channel conditions, the Reference Signals in the control region serve as a good candidate for estimating these parameters, which in turn can be used for estimation channel for the data region. If the spatial parameters and properties of the channel are indicated to be the same for data and control transmissions, the receiver could potentially use the same receiving beamforming patterns or similar receiving beamforming patterns to receive both control as the data.
[0080] As noted above, in beam-formed systems (for example, in Wave frequencies mm), the control region and the data region may not use the same beam all the time. In some cases, the UE can be reached only by a narrow beam used for data transmissions. In such cases, the UE may not be aware of the region's control information to explore the channel estimate for the data region.
[0081] However, aspects of the present disclosure provide techniques in which the transmitting entity can signal information relating to a relationship between the beams used for data and control transmissions. As used in this document,
Petition 870190042984, of 7/7/2019, p. 41/76
36/50 control transmissions generally refer to the control channel transmission (for example, PDCCH in DL, PUCCH in UL), as well as reference signals (for example, CSI-RS or SS in DL, SRS in UL). The control and data can be in the same sub-band, in different sub-bands of a component carrier or in different component carriers. The data may include DMRS used to demodulate the data. The techniques can be used to signal information that can be used to process downlink transmissions, uplink transmissions, or both. The uplink and downlink transmissions can be the same, in different sub-bands of a component carrier or in different component carriers.
[0082] For example, a base station (for example, an eNB or UE that acts as a base station in device to device or D2D scenario) may signal, for a UE, a relationship between the beams used for data transmissions. control (for example, for PDCCH or RS of DL, such as SS and / or CSI-RS) and for data transmissions (for, for example, PDSCH or RS included with PDSCH, such as DMRS or PTRS). The UE can then use this information for channel estimation in both the downlink control regions. Similarly, a UE can signal to a base station a relationship between the beams used for control transmissions (for example, for PUCCH or SRS) and for data transmissions (for, for example, PUSCH). The base station can then use this information for channel estimation in both the uplink control regions and the data regions. The relationship
Petition 870190042984, of 7/7/2019, p. 42/76
37/50 signaled by the UE can be one out of a set of possible relationships, in which the set can be configured by the base station. In another aspect, the base station can signal this relationship to the UE instead of allowing the UE to choose and signal its choice to the base station.
[0083] Figure 9 illustrates exemplary 900 operations that can be performed by a transmission entity. For example, operations 900 can be performed by a BS that includes one or more modules of the BSs 110 shown in Figure 4 or by a UE that includes one or more modules of the UEs 120 shown in Figure 4.
[0084] Operations 900 begin, in 902, by signaling, to a receiving entity, information relating to a relationship between the beams used for data transmission and control to the receiving entity. Operations continued, in 904, by sending control and data transmissions using beams.
[0085] Figure 10 illustrates 1000 exemplary operations that can be performed by a receiving entity (for example, a UE or base station) according to the aspects of the present disclosure. Operations 1000 can be considered complementary side X-ray operations for side TX 900 operations.
[0086] Operations 1000 begin, in 1002, with the receiving entity that receives the signaling, from a transmitting entity, information related to a relationship between the beams used for control and data transmissions to the receiving entity . In 1004, the receiving entity processes the
Petition 870190042984, of 7/7/2019, p. 43/76
38/50 control and data transmissions based on signaled information.
[0087] According to the aspects of the present disclosure, an eNB can signal the beam relationship between the beams used during the control transmission (for example, for PUCCH) and the data transmission (for example, for PUSCH). In this case, the signaling of beam association information can be through radio resource control (RRC), PUCCH signaling or a medium access control (MAC) control element (MAC).
[0088] According to the aspects of the present disclosure, an eNB can signal the beam relationship between the beams used during a control transmission (for example, for PDCCH) and a data transmission (for example, for PDSCH). In some cases, eNB may signal a configuration of transmission time intervals (for example, partitions and / or subframes) and the type of beam associations between data and control channel transmissions at those intervals.
[0089] For example, this information can indicate certain intervals during which the same beams are used for both control and data. Based on this information, a UE may have the ability to use RS transmitted in the control region to estimate the channel in the data region (or vice versa). At other intervals, the beams can be different, for example, with broader beams for control than the data (as shown in Figure 8). This allows flexibility for an eNB (for example, to transmit to multiple UEs during certain intervals).
Petition 870190042984, of 7/7/2019, p. 44/76
39/50
[ 0090 ] A signaling of information in Association in beam i of an eNB can be through gives signaling in control appeal radio (RRC), PDCCH, signaling in diffusion (for example , MIB / SIB) or a CE in MAC.[ 0091 ] The parameters flagged can include several types of information association, such as if
both control and data are programmed using the same beam or phase continuity between control and data reference (RS) signals. The signaled parameters can include a measure of correlation between the beam formats applied in the control and data regions. In some cases, the signaled parameters may include an indication of near colocalization between the beams used in the Control and Data regions. This signaling can allow a receiving device to know if it can consider QCL (or a degree of quasi-colocalization considered) of control and data to estimate parameters, such as Doppler Scattering, delay spread, frequency and timing, and use these to data channel estimate. Alternatively or additionally, signaling may also allow a receiving device to know whether it can consider whether certain control and data components are spatial QCL'd, meaning QCL in relation to spatial properties, such as shape or starting beam angle (AoD) of a transmitter. Spatial QCL information can, for example, allow a receiver to use the same receiving beam formation for 2 signals (data and control) that are indicated as spatial QCL'd.
Petition 870190042984, of 7/7/2019, p. 45/76
40/50 [0092]
In any case, the receiving device can use this information related to the beam association to improve the channel estimate, both for the data as well as for the control region. In some cases, a UE may receive signals that the data channel (PDSCH) and the control channel (PDCCH) will be transmitted using the same beam. In this case, the UE can use the same RS to estimate parameters for both the control and data regions.
For example, if the signaling indicates that the same beam is used for control and data transmissions (or that the indicated control and data transmissions of signaled parameters are likely to experience the same channel conditions, a UE can use DMRS in the control region to estimate parameters such as delay spread, Doppler, frequency error, timing error, etc. The UE can use this information to improve the channel estimate for the data region.
[0094]
In some cases, control and data transmission features overlap in at least some of the same frequency tones. As an example, the control can be from 10 to 20Mhz, while the data is from 10 to 30Mhz or from 15 to 25Mhz. In this case, if the phase continuity is signaled as well, then this information can be used by the UE to further improve the channel estimate and also to estimate certain fine imperfections, such as frequency error.
[0095]
As noted above, because it has partitions / subframes where the data and control will use the
Petition 870190042984, of 7/7/2019, p. 46/76
41/50 same beam and other partitions / subframes where data and control use different beams, an eNB may have some flexibility.
[0096] For example, eNB can apply broader beams to some partitions to program multiple UEs, while narrower beams (corresponding to the data beam) in other partitions help to improve the channel estimate for the programmed UE. In other words, the UE only programmed in those partitions and subframes can use the control beam to estimate the channel parameters (for example, delay spread, Doppler, frequency error and the like). This information can then be used to improve the channel estimate for the data region.
[0097] As noted above, the similar beam association can be signaled (by EnodeB / or by UE) for the Uplink also, for example, if the PUCCH (uplink control) and PUSCH (uplink data) share the same beam and EnodeB can use the PUCCH RS to estimate parameters for PUSCH. When considering that PUSCH and PUCCH are in different symbols and that both have RS, they can be beneficial for signaling QCL between RS and uniform phase continuity. ENodeB can signal this to the UE or the UE can report saying that it will use the same beam for both PUCCH and PUSCH.
[0098] In some cases, the techniques described in this document can be extended to device-to-device (D2D) scenarios, for example, where 2 UEs are in communication with a potentially element
Petition 870190042984, of 7/7/2019, p. 47/76
42/50 playing the role of traditional BS. In such cases, an UE that serves as the BS (that receives on the uplink) can tell the other UE (that transmits on the UL) how to relate the UL's control and UL data beams). In some cases, a UE may choose (provide the signaling) for UL. In other cases, a BS can choose for UL.
[0099] In some cases, beam ratio information can be carried as a beam ratio metric. The beam ratio metric can, for example, specify the relationship between multiple control transmissions (for example, PDCCH and / or CSIRS) and data transmissions (for example, PDSCH and / or CSIRS) and can be generated as a function one or more beam parameters used for control and data transmissions. By providing these indications separately, a device can specifically determine whether the control and data (for example, PDCCH and PDSCH) are QCLed or not.
[0100] The methods disclosed in this document comprise one or more steps or actions to achieve the described method. The steps and / or method actions can be interchanged with one another without departing from the scope of the claims. In other words, unless a specific order of steps or actions is specified, the order and / or use of specified steps and / or actions can be modified without departing from the scope of the claims.

[0103] The previous description is provided to enable anyone skilled in the art to practice the various aspects described in this document. Various modifications to those aspects will be readily apparent to those skilled in the art, and the generic principles defined in this document can be applied to other aspects. Thus, it is intended that the claims are not limited to the aspects shown in this document, but are in accordance with the full scope consistent with the language of the claims, in which the reference to an element in the singular is intended to mean one and only one , unless specifically stated, but one or more. Unless stated otherwise, the term does not refer to one or more. All structural equivalents and
Petition 870190042984, of 7/7/2019, p. 49/76
44/50 functional elements for the elements of the various aspects described throughout this disclosure that are known or will be known later on by those of ordinary skill in the art are expressly incorporated into this document by way of reference and are intended to be covered by the claims. In addition, it is intended that nothing disclosed in this document is dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element shall be construed under the provisions of 35 USC §112, sixth paragraph, unless the element is expressly recited using the phrase means for or, in the case of a method claim, the element is recited with the use of the phrase step to.
[0104] The various method operations described above can be performed by any means capable of carrying out the corresponding functions. The means may include various components and / or hardware and / or software modules, which include, but are not limited to, a circuit, an application specific integrated circuit (ASIC) or processor. In general, where there are operations illustrated in the figures, those operations may have function components plus means of equivalence with
numbering similar. [0105] The several logic blocks, modules and circuits illustrative described together with this revelation can to be implanted or carried out with one purpose processor I'm general , a signal processor digital (DSP), one circuit specific integrated in application (ASIC), one get it programmable doors in
Petition 870190042984, of 7/7/2019, p. 50/76
45/50 field (FPGA) or other programmable logic device (PLD), discrete port or transistor logic, discrete hardware components, or any combination of them designed to perform the functions described in this document. A general purpose processor may be a microprocessor, but in the alternative, the processor may be a commercially available processor, controller, microcontroller, or state machine. A processor can also be deployed as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core or any other such configuration.
[0106] If deployed on hardware, an exemplary hardware configuration can comprise a processing system on a wireless node. The processing system can be implemented with a bar architecture. The bar can include any number of interconnected bars and bridges depending on the specific application of the processing system and general design constraints. The bus can connect several circuits including a processor, machine readable media and a bus interface. The bus interface can be used to connect a network adapter, among other things, to the processing system via the bus bus. The network adapter can be used to implement the PHY layer signal processing functions. In the case of a 120 user terminal (see Figure 1), a user interface (for example, keyboard, display, mouse, joystick, etc.) can also be connected to the bar. The bar can also connect several
Petition 870190042984, of 7/7/2019, p. 51/76
46/50 other circuits with timing sources, peripheral elements, voltage regulators, power management circuits and the like, which are well known in the art, and therefore will not be described further. The processor can be deployed with one or more general purpose and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors and other circuitry that can run the software. Those skilled in the art will recognize the best way to implement the described functionality of the processing system depending on the particular application and the general design restrictions imposed on the general system.
[0107] If implemented in software, functions can be stored or transmitted as one or more instructions or code in a computer-readable medium. The software must be constructed widely to signify instructions, data or any other combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language or otherwise. The computer-readable media includes both the computer storage media and the communication media that includes any medium that facilitates the transfer of a computer program from one place to another. The processor can be responsible for managing the bar and general processing, including the execution of software modules stored on machine-readable storage media. A computer-readable storage medium can be coupled to a processor so that the processor can read information from and write information
Petition 870190042984, of 7/7/2019, p. 52/76
47/50 for the storage medium. Alternatively, the storage medium can be integral to the processor. By example, the computer-readable media can include a transmission line, a carrier wave modulated by the data and / or a computer-readable storage medium with instructions stored on it separate from the wireless node, all of which can be accessed by the processor through the bar interface. Alternatively or additionally, the machine-readable media, or any portion of it, can be integrated into the processor, as the case may be with cache and / or general log files. Examples of machine-readable media may include, by example, RAM (Random Access Memory), flash memory, ROM (Read-Only Memory), PROM (Programmable Read-Only Memory), EPROM (Programmable, Erasable Read-Only Memory) , EEPROM (Electrically Erasable Programmable Read Only Memory), registers, magnetic disks, optical disks, hard drives or any other suitable storage medium, or any combination thereof. Computer-readable media can be incorporated into a computer program product.
[0108] A software module can comprise a single instruction, or many instructions, and can be distributed over several different segments of code between different programs and through the medium of multiple storage. The computer-readable media can comprise several software modules. The software modules include instructions that, when executed by a device such as a processor, cause the processing system to perform various functions. The modules
Petition 870190042984, of 7/7/2019, p. 53/76
48/50 software can include a transmit module and a receive module. Each software module can reside on a single storage device or be distributed across multiple storage devices. For example, a software module can be loaded into RAM from a hard disk when a trigger event occurs. During the execution of the software module, the processor can load any of the instructions to increase the speed of access. One or more lines of cache can then be loaded into a general log file for execution by the processor. When referring to the functionality of a software module below, it will be understood that such functionality is implemented by the processor when executing the instructions of that software module.
[0109] Furthermore, any connection is properly called from a computer-readable medium. For example, if the software is transmitted from a web page, server or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) or wireless technologies such as infrared (IR), radio and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwave are included in the definition of medium. The magnetic disk and the optical disk, as used in this document, include compact disk (CD), disk, optical disk, versatile disk (DVD), floppy disk and Blu-ray® disk in which magnetic disks usually reproduce data magnetically, while optical discs reproduce data ethically with
Petition 870190042984, of 7/7/2019, p. 54/76
49/50 lasers. Thus, in some respects, computer-readable media may comprise non-transitory computer-readable media (for example, tangible media). In addition, for other aspects, the computer-readable media may comprise the transient computer-readable media (e.g., a signal). Combinations of the above should also be included within the scope of the computer-readable media.
[0110] Thus, certain aspects may comprise a computer program product to perform the operations presented in this document. For example, such a computer program product may comprise a computer-readable medium that has instructions stored (and / or encoded) therein, where the instructions are executable by one or more processors to perform the operations described in this document. For example, the instructions for performing the operations described in this document and illustrated in Figures 9 to 10.
[0111] Additionally, it should be appreciated that the modules and / or other appropriate means for carrying out the methods and techniques described in this document can be downloaded and / or otherwise obtained by a user terminal and / or base station as applicable. For example, such a device can be coupled to a server to facilitate the transfer of means to carry out the methods described in this document. Alternatively, several methods described in this document can be provided through storage media (for example, RAM, ROM, physical storage media such as a disk
Petition 870190042984, of 7/7/2019, p. 55/76
50/50 compact (CD) or floppy disk, etc.), so that a user terminal and / or base station can obtain the various methods by coupling or providing storage media for the device. In addition, any other technique for providing the methods and techniques described in this document for a device can be used.
[0112] It should be understood that the claims are not limited to the precise configuration and the components illustrated above. Various modifications, alterations and variations can be made in the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
