Technical Field

[0003]

[0011] Generally speaking, aspects of the disclosure relate to wireless communications and to techniques and apparatus for set-based 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 use multiple access technologies that can support communication 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). 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 several base stations (BS) that can support communications for several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. 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 multiple access technologies have been adopted in a variety of telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, and even global level. New Radio (NR) (which may also be referred to as 5G) is an enhancement set of the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed 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) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., it is also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) Better integration and support for beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technology. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0075] The various aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in a variety of different forms, and it should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, providing these aspects will 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 disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with it. For example, a device may be implemented or a method may be practiced using any number of aspects set forth herein. In addition, the scope of protection of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions in addition to or different from 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 in the claims.

[0076] 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 detailed description below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0077] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later (including NR technology).

[0078] Figure 1is a diagram showing 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 (e.g., a 5G or NR network). The wireless network 100 may include several 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), and the like. 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 "cell" is used.

[0079] 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., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by 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 for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. 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.

[0080] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections, virtual networks, etc.) using any appropriate transport network.

[0081] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data 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 in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0082] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., 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 higher 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).

[0083] 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 backhaul or a wired backhaul.

[0084] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary 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 device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, 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 device), a vehicle-mounted 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 medium or a wired medium.

[0085] Some UEs may be considered as 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. that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide a connection 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 as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as user premises equipment (CPE). UE 120 may be included in a housing that houses components (e.g., processor components and / or memory components) of UE 120. In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0086] Generally, in a given geographic area, any number of wireless networks can be deployed. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as wireless technology, air interface, etc. Frequency can also be referred to as carrier, frequency 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 can be deployed.

[0087] 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) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0088] As indicated above, Figure 1 Other examples can be found in Figure 1 The examples described are different.

[0089] Figure 2A 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.

[0090] 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 the UE based at least in part on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each 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)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and up-convert) to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0091] 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) the received signal to obtain input samples. Each demodulator 254 may also 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 indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0092] 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 transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decode control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

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, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120, may perform or instruct, for example, Figure 7 The process of 700 Figure 8 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0094] 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.

[0095] In some aspects, UE 120 may include: a unit for receiving an indication of one or more candidate beam sets from a base station, wherein each candidate beam set includes a first beam combination and a second beam combination, the first beam combination includes a first beam as a channel measurement resource (CMR) and a second beam as an interference measurement resource (IMR) for measuring interference of the second beam to the first beam, and the second beam combination includes the second beam as a CMR and the first beam as an IMR; a unit for determining, for each candidate beam set in the one or more candidate beam sets, a measurement value for the first beam combination and a measurement value for the second beam combination; a unit for determining a candidate set of beams to be reported in the one or more candidate beam sets based at least in part on the measurement value; a unit for sending a measurement report to the base station, the measurement report indicating a first measurement value for the first beam combination of the candidate set of beams and a second measurement value for the second beam combination of the candidate set of beams; and so on. In some aspects, such a unit may include combining Figure 2One or more components of UE 120 are depicted, such as a controller / processor 280, a transmit processor 264, a TX MIMO processor 266, modulators 254, antennas 252, demodulators 254, MIMO detectors 256, a receive processor 258, and the like.

[0096] In some aspects, the base station 110 may include: a unit for determining one or more candidate beam sets for sending communications to a UE, wherein each candidate beam set includes a first beam combination and a second beam combination, the first beam combination includes a first beam as a CMR and a second beam as an IMR for measuring interference of the second beam to the first beam, and the second beam combination includes the second beam as a CMR and the first beam as an IMR; a unit for sending an indication of the one or more candidate beam sets to the UE; a unit for receiving a measurement report from the UE, the measurement report indicating a first measurement value for a first beam combination of the candidate set of beams in the one or more candidate beam sets and a second measurement value for a second beam combination of the candidate set of beams; and so on. In some aspects, such a unit may include combining Figure 2 One or more components of the base station 110 are depicted, such as an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, and the like.

[0097] As noted above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0098] 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. Accordingly, 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 in 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 channel state information reference signal (CSI-RS), as shown in reference numeral 312. The base station may send CSI-RS or synchronization signal blocks (SSBs) on multiple beams, as shown in 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 (SS / PBCH) resource block indicator (SSB-RI) in the message, as shown in reference numeral 316. The message may also include an associated reporting quantity (e.g., RSRP or signal to interference plus noise ratio (SINR)). The gNB may send an RRC reconfiguration message to the UE based 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 on the first beam and the second beam simultaneously. The two beams may belong to the same transmit and receive point (TRP) or to different TRPs. A TRP may be associated with a beam set.

[0099] As noted above, Figure 3 is provided as an example. Other examples may differ from those described above. Figure 3 Examples described.

[0100] The UE may determine candidate beams for reporting measurement information. The UE may measure beams independently and report measurements (e.g., RSRP) for a single beam or a set of beams. If the UE is to measure the beams jointly, the UE may use the layer 1 signal to interference plus noise ratio (L1-SINR) as a metric that takes into account cross-beam interference. Specifically, the UE may calculate the L1-SINR for each beam based at least in part on the channel measurement resources (CMR) for the signal portion and the interference measurement resources (IMR) for the interference plus noise portion. For example, the UE may measure one beam for the CMR portion and another beam for the IMR portion. These two beams (one for CMR and one for IMR) may be considered a beam combination.

[0101] The UE may determine to report the beam with the highest L1-SINR. However, the report may not reflect the cross interference between this beam and another beam because the corresponding IMR may be configured to be sent by a different beam than the beam for which the UE may report. The report may result in less accurate channel and interference information, which may degrade the decisions made by the transmitting device and degrade the transmission quality. Degraded transmissions may cause the UE and BS to waste processing resources and signaling resources on unsuccessful transmissions or retransmissions.

[0102] According to various aspects described herein, a BS may provide a candidate beam set (beam group) for reporting to a UE. The UE may report measurements for all beam combinations in a determined candidate beam set. Each set may include two beam combinations. A first beam combination may include a first beam for a CMR and a second beam for an IMR. A second beam combination for the same set may include a second beam for a CMR and a first beam for an IMR. In this way, the UE may report on a candidate beam set (beams and interference beams) instead of reporting on a single beam. Therefore, the base station may obtain more information considering cross-beam interference. Information for a candidate beam set may result in more accurate channel and interference information, which may improve decisions made by a transmitting device and improve transmission quality. Improved transmission quality may enable the UE and BS to save processing resources and signaling resources that would otherwise be wasted on unsuccessful transmissions or retransmissions.

[0103] Figure 4 An example 400 of beam combinations in a candidate beam set according to various aspects of the present disclosure is shown. In some aspects, a BS (e.g., TRP, gNB) may provide multiple candidate beam sets. Figure 4 A table with 8 columns is shown, where each column is a beam combination specified, for example, using a CMR identifier (ID) and an IMR ID. In the first beam combination, a CMR ID of 0 and an IMR ID of 8 indicate that beam 1 is a beam for CMR and beam 3 is a beam for IMR. In the second beam combination, a CMR ID of 1 and an IMR ID of 9 indicate that beam 3 is a beam for CMR and beam 1 is a beam for IMR. In this example, there are 8 columns or 8 beam combinations. The UE can report any individual beam combination without fully considering cross-beam interference.

[0104] In some aspects, the BS may indicate one or more candidate beam sets, where each set is a two-beam combination, as described above. For example, a first beam combination of beam 1 for CMR and beam 3 for IMR is in candidate set 1 with a second beam combination of beam 3 for CMR and beam 1 for IMR. Therefore, if the UE measures one of these beam combinations and determines to report a beam combination (e.g., a higher SINR relative to the SINR of the other beam combinations), instead of reporting a separate high SINR beam combination, the UE may report two beam combinations in the set where the high SINR beam combination is located. In this way, the BS may determine the cross-beam interference involved between the two beams in candidate set 1. The cross-beam interference may cause the BS to determine that selecting beam 1 and beam 3 may not be optimal for simultaneous transmission, and the BS may select beam pairs from other candidate sets for communication.

[0105] Figure 4 Four candidate sets are shown, and not all possible beam combinations are represented. The BS may select candidate sets of which beam combinations to provide to the UE. The BS may determine the candidate set based at least in part on UE capabilities, UE location, UE speed, UE direction, predicted location of the UE, etc. Other metrics for measurement may include L1-SINR, L1-RSRP, channel quality indicator, throughput, mutual information between beams, etc. Although the candidate set of beams is described as having two beam combinations, in some aspects the candidate set may include more than two beam combinations. In some aspects, the beam combination may include CMR and IMR configurations for more than two beams.

[0106] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0107] 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. 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 4 UE) for communicating with a BS 510 (e.g., Figure 1 and 2 BS 110, as depicted in Figure 3 The gNB depicted in Figure 4 BS 510 may send communications to UE 520 on at least two simultaneous beams.

[0108] As in Figure 5 5 and as shown by reference numeral 530, BS 510 may determine one or more candidate beam sets for sending communications to UE 520. Each candidate beam set may include a first beam combination and a second beam combination. The first beam combination may include a first beam as a CMR and include a second beam as an IMR for measuring interference of the second beam to the first beam. The second beam combination may include a second beam as a CMR and include a first beam as an IMR. BS 510 may determine one or more candidate beam sets based at least in part on capabilities of the UE, a location of the UE, a speed of the UE, a direction of the UE, a predicted location or path of the UE, feedback from the UE, and the like.

[0109] As indicated by reference numeral 535, the BS 510 may send an indication of a candidate beam set to the UE 520. The indication may be an explicit resource identifier (CMR ID, IMR ID) or an explicit beam set identifier. Additionally or alternatively, the indication may be an implicit identifier, wherein the UE 520 may determine one or more candidate beam sets based at least in part on the implicit indication. In some aspects, the beam combination may be part of a list, and the UE may determine one or more candidate sets based at least in part on the ranking of the beam combinations in the list and / or the indication. For example, two adjacent resources or adjacent beam combinations may form each candidate beam set. The UE may have received a message from the gNB configuring the UE with the list, ranking information, identifier information, etc.

[0110] Figure 6 A continuation of example 500 is shown. Figure 6 And as shown by reference numeral 630, UE 520 can determine the measurement (e.g., L1-SINR, etc.) of the beam combination of CMR and IMR for one or more beam candidate sets indicated by BS 510. It may be effective to measure the beam combination of each candidate beam set. UE 520 can determine the beam combination to be reported (e.g., high L1-SINR). As shown by reference numeral 635, UE 520 can determine the candidate beam set for which the measurement value is to be reported based at least in part on the measurement value. For example, UE 520 can determine to report two beam combinations of the candidate set having the beam combination with the highest measured L1-SINR. In some aspects, the highest average value of the beam combination can be considered. In some aspects, UE 520 can determine the candidate beam set to be reported based at least in part on maximizing the sum of the L1-SINR of each beam in all candidate beam sets.

[0111] As indicated by reference numeral 640, the UE 520 may send an indication of the measurement value to the BS 510. The indication may also indicate information for identifying a candidate beam set or a beam combination of the candidate beam set.

[0112] As noted above, Figure 5 and 6 is provided as an example. Other examples may differ from those described above. Figure 5 and 6 Examples described.
