[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 967,348, filed on January 29, 2020, entitled “TECHNIQUES FOR INDICATING BEAMS FOR USER EQUIPMENT BEAM REPORTING,” and U.S. Non-Provisional Patent Application No. 17 / 247,165, filed on December 2, 2020, entitled “TECHNIQUES FOR INDICATING BEAMS FOR USER EQUIPMENT BEAM REPORTING,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for indicating beams for user equipment beam reporting. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that are capable of supporting communications with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE) systems. LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include multiple base stations (BSs) that may support communications for multiple user equipment (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. A downlink (or forward link) refers to a communication link from a BS to a UE, and an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and / or the like.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, or even global level. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR aims to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to increase, further improvements in LTE and NR technologies are needed. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0111] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or implementation method. In addition, the scope of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions other than or in addition to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0112] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0113] It should be noted that although various aspects may be described herein using terms typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to other generation-based communication systems, such as 5G and later communication systems, including NR technologies.

[0114] Figure 1 1 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include a plurality of BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0115] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS of macro cell 102a, BS 110b may be a pico BS of pico cell 102b, and BS 110c may be a femto BS 102c of a femto cell. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0116] In some aspects, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of the mobile BS. In some aspects, a BS may be interconnected to another BS or one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar devices using any suitable transport network).

[0117] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0118] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0119] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0120] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be fixed or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0121] Some UEs may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (e.g., processor components, memory components, etc.).

[0122] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0123] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In such cases, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0124] As mentioned above, providing Figure 1 As an example. Other examples may be related to Figure 1 Different than described.

[0125] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0126] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). If applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 can process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted through T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding can be used to generate synchronization signals to convey additional information.

[0127] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) received signals to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indication (RSSI), reference signal received quality (RSRQ), CQI, etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0128] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 through the communication unit 244 . The network controller 130 may include a communication unit 294 , a controller / processor 290 , and a memory 292 .

[0129] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The operation of process 700, Figure 8 800, and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 7 The process of 700 Figure 8 The operations of process 800 of , and / or other processes described herein. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0130] In some aspects, the candidate beams may include channel state information reference signal (CSI-RS) resources and / or synchronization signal block (SSB) resources. The resources may have associated transmission configuration indicator states, spatial filter parameters, and / or quasi-co-location properties. For ease of explanation, in the examples described herein, such resources may be referred to as beams.

[0131] In some aspects, UE 120 may include means for receiving, from a base station, an indication of a plurality of candidate beams on which the base station can simultaneously transmit communications to the UE, means for determining a first beam and a second beam from the plurality of candidate beams based at least in part on one or more measurements of the plurality of candidate beams, means for sending the indication of the first beam and the second beam to the base station, etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0132] In some aspects, base station 110 may include means for determining a plurality of candidate beams on which the base station may simultaneously transmit communications to the UE, means for sending an indication of the plurality of candidate beams to the UE, means for receiving from the UE an indication of a first beam and a second beam on which the UE may simultaneously receive communications from the base station, etc. In some aspects, such means may include combining Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0133] As mentioned above, providing Figure 2 As an example. Other examples may be related to Figure 2 Different than described.

[0134] Figure 3An example process 300 for beam reporting by a UE for simultaneous beam communication is shown. A base station (e.g., a gNB) may plan to transmit on two beams simultaneously, and a corresponding UE may plan to receive on two beams simultaneously. Thus, the gNB and the UE may begin to establish communication via a radio resource control (RRC) configuration message (e.g., CSI-MeasConfig, CSI-ReportConfig, CSI-ResourceConfig), as shown by reference numeral 310. The gNB may send a medium access control-control element (MAC-CE) or use a downlink control information (DCI) trigger to activate a semi-persistent or aperiodic CSI-RS, as shown by reference numeral 312. The base station may send CSI-RS or SSB on multiple beams, as shown by reference numeral 314. The UE may measure the beams and report channel information and / or interference information to the gNB. The UE may report channel information and / or interference information. For example, the UE may report a CSI-RS resource indicator (CRI) or a synchronization signal physical broadcast channel (SSB) resource block indicator (SSB-RI) in the message, as shown in reference numeral 316. The message may also include an associated report number (e.g., RSRP or signal to interference and noise ratio (SINR)). The gNB may send an RRC reconfiguration message to the UE based at least in part on the report from the UE, as shown in reference numeral 318, and send a MAC-CE activation or deactivation message, as shown in reference numeral 320. The gNB may then send communications to the UE simultaneously on the first beam and the second beam. The two beams may belong to the same transmit and receive points (TRP) or to different TRPs. A TRP may be associated with a beam set.

[0135] As mentioned above, providing Figure 3 As an example. Other examples may be related to Figure 3 Different than described.

[0136] In some scenarios, if the gNB cannot transmit on both beams simultaneously, the UE may report one or two other beams after knowing that the gNB will not transmit on both beams simultaneously. These extra steps to establish communication on one or two other beams that the gNB can handle may cause the UE and gNB to waste power, processing resources, and signaling resources.

[0137] According to various aspects described herein, a gNB may determine candidate beams on which the gNB may transmit simultaneously. The gNB may indicate the candidate beams to the UE, and the UE may select two beams from the candidate beams. In some aspects, the gNB may signal the candidate beams with an indication including an index corresponding to the candidate beam or a set (group) of candidate beams (e.g., a TRP index, a physical cell identity index, a control resource set pool index). The candidate beams may include more than one candidate beam set, and the UE may select two beams in different candidate beam sets. The UE and the base station may be able to communicate on two beams simultaneously without having to restart the beam reporting process with the gNB. The UE and the gNB may therefore save power, processing resources, and signaling resources.

[0138] Figure 4 An example process 400 for beam reporting by a UE for simultaneous beam communications is shown in accordance with various aspects of the present disclosure. Figure 4 shows a gNB that can communicate with a UE, similar to the combination of Figure 3 The process shown.

[0139] In some aspects, the gNB may indicate the beams on which the gNB may transmit simultaneously. As shown in reference numeral 410, the indication may be included in an RRC configuration message, a MAC-CE, a DCI, a CRI, an SSB resource indicator, etc. The indication may also be indicated in an existing information element (IE) (e.g., NZP-CSI-RS-Resource IE, CSI-SSB-ResourceSet IE, NZP-CSI-RS-ResourceSet IE) or a new IE. Additionally or alternatively, the gNB may configure the mapping between each beam set index and the corresponding beam (resource) for the UE using an existing IE or a new IE. The mapping may include an associated RS resource identifier (ID) or a resource set ID.

[0140] In some aspects, the gNB may implicitly indicate a candidate beam or candidate beam set by indicating an index of the candidate beam or candidate beam set. The UE may determine the candidate beam based at least in part on the index, as shown by reference numeral 420. For example, beams with RS resource set IDs of 0, 2, 4, 6, ... may have a beam set index of 0, while beams with RS resource sets with IDs of 1, 3, 5, 7, ... may have a beam set index of 1. The gNB and the UE may use a mapping rule that associates the index with the resource set ID of the candidate beam. The gNB may configure the mapping rule for the UE (e.g., via RRC, MAC-CE, DCI).

[0141] In some aspects, the UE may determine the candidate beams based at least in part on the ranking of the beams in the indication. The beams may be part of a list used to define a beam set. For example, beams with rankings of 0, 2, 4, 6, ... in the list may have a beam set indexed as 0, while beam sets with rankings of 1, 3, 5, 7, ... in the list may have a beam indexed as 1. The gNB may configure a mapping rule or list for the UE to associate the beam ranking in the indication with an index or identifier of the beam.

[0142] As mentioned above, providing Figure 4 As an example. Other examples may be related to Figure 4 Different than described.

[0143] Figure 5 and 6 is a diagram illustrating an example 500 of indicating beams for UE beam reporting in accordance with various aspects of the present disclosure.

[0144] Figure 5 and 6 5 shows a method that can be used with UE 520 (e.g., Figure 1 and 2 UE 120 depicted in Figure 3 and Figure 4 UE) communicating with BS 510 (e.g., Figure 1 and 2 BS 110 depicted in Figure 3 and 4 BS 510 may send communications to UE 520 simultaneously on at least two beams.

[0145] like Figure 5 And as shown in reference numeral 530, BS 510 can determine multiple candidate beams, and BS 510 can send communications to UE 520 simultaneously on these candidate beams. BS 510 can determine the multiple candidate beams based at least in part on the capabilities of the UE, the location of the UE, the speed of the UE, the direction of the UE, the predicted location or path of the UE, feedback from the UE, etc.

[0146] As indicated by reference numeral 535, the BS 510 may send an indication of a plurality of candidate beams to the UE 520. The indication may include an explicit beam identifier or a beam set identifier. The indication may be an implicit identifier, wherein the UE 520 may determine the candidate beams based at least in part on the indication. The UE may have received a message from the gNB configuring the UE to make the implicit determination.

[0147] Figure 6 A continuation of example 500 is shown. Figure 6And as shown by reference numeral 540, UE 520 may determine a first beam and a second beam for simultaneously receiving communications from BS 510. UE 520 may determine the first beam and the second beam based at least in part on measurements (e.g., SINR, etc.) of one or more candidate beams. UE 520 may compare the beam measurements with a threshold and select a beam based at least in part on the comparison. In some aspects, UE 520 may measure each of the candidate beams indicated by BS 510. Additionally or alternatively, UE 520 may determine more than two beams for simultaneous transmission for reporting.

[0148] As indicated by reference numeral 545, the UE 520 may send an indication of the first beam and the second beam to the BS 510. As indicated by reference numeral 550, the BS 510 and the UE 520 may communicate by simultaneously transmitting and receiving on the first beam and the second beam.

[0149] In some aspects, after receiving a report (e.g., groupBasedBeamReport) from UE 520, BS 510 may send a message or instruction to UE 520 that the first beam and the second beam cannot be processed simultaneously and are not combined together until further notice. The message may be a grouping or set indication of the prohibited beam sets.

[0150] As mentioned above, providing Figure 5 and 6 As an example. Other examples may be related to Figure 5 and 6 Different than described.

[0151] Figure 7 700 is a diagram illustrating an example process 700 performed, for example, by a UE according to various aspects of the present disclosure.

[0154] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include sending an indication of the first beam and the second beam to the base station (block 730).
