[0036] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0037] The continuous emergence of new-generation Internet applications has placed higher demands on wireless communication technology, driving its continuous evolution to meet application needs.

[0038] To better support vehicle-to-everything (V2X) communication, LTE V2X was defined in LTE Release 14, enabling direct communication between V2X devices (such as vehicles-to-vehicle, vehicle-to-pedestrian, and vehicle-to-roadside nodes) via direct links. Release 15 further enhanced LTE V2X technology, supporting features such as carrier aggregation. Following the release of 5G New Radio (NR) technology in Release 15, 3GPP initiated work on supporting V2X communication using the NR interface, completing 5G Sidelink in Release 16, supporting direct communication between V2X devices via NR technology. Release 17 further enhanced NR Sidelink in areas including energy efficiency and reliability.

[0039] Beam management support was not considered in LTE V2X and Release 16 NR V2X because the primary frequency bands for V2X applications at that time were located in lower spectrum locations. However, with technological advancements, using higher millimeter-wave bands for Sidelink communication has become possible. When using millimeter-wave bands (e.g., FR2 band), analog beamforming or hybrid analog-digital beamforming is generally employed. When both the transmitting and receiving UEs use analog beamforming, to achieve better communication quality, the transmitting and receiving beams need to be paired to form a beam pair with better communication quality. Therefore, beam management support is required in Sidelink.

[0040] In traditional NR DL or UL communication, beam management is performed using reference signals such as downlink PSFCH (Physical Sidelink Feedback Channel), CSI-RS, or uplink SRS (Sounding Reference Signal). The UE determines the receive beam to use when receiving different reference signals or reference signals at different resource locations by receiving and measuring the reference signals sent by the base station. The base station manages the UE's receive beam by instructing the UE to use the same reference signal or reference signal at which resource location when receiving PDSCH (Physical Downlink Shared Channel) (QCLTypeD). The specific protocol for how the UE determines the receive beam through reference signal measurement is not specified.

[0041] Depending on the UE's capabilities, NR supports the UE simultaneously receiving two PDSCHs corresponding to different RS or RS resources (e.g., FDM (Frequency Division Multiplexing) PDSCHs transmitted from two different TRPs). Since both uplink and downlink of the UE are controlled by the base station scheduling, the base station scheduling can ensure that the UE will not need to simultaneously receive multiple PDSCHs requiring different receive beams that exceed its capacity.

[0042] NR SL supports a resource allocation scheme based on UE autonomous scheduling. A single UE may simultaneously receive PSCCH / PSSCH (Physical Sidelink Control Channel) transmitted by multiple UEs on different frequency domain subchannels within the same slot. Different UEs' PSCCH / PSSCH may correspond to different receive beam directions. Without a central node for coordination, the UE cannot guarantee that the number of received beams will not exceed its capacity. Correspondingly, the UE also needs to be able to simultaneously receive FDM / CDM (Code Division Multiplexing) PSFCH from multiple UEs, as different PSFCH may originate from different UEs and may correspond to different receive beam directions.

[0043] Furthermore, in NR SL, the UE needs to perform reception operations such as sensing and CBR (Quasi Co-location) measurements. In Release 16 / 17 / 18, since analog beamforming is not considered, these reception operations can be performed simultaneously with the UE's reception of PSCCH / PSSCH / PSFCH / S-SSB. When the UE uses analog beamforming, the reception beam used for these reception operations may be different from the reception beam used to receive the PSCCH / PSSCH transmitted by a specific UE. Due to the current capabilities of the UE, conflicts also exist between these reception operations.

[0044] Therefore, in NR SL beam management, when a UE needs to use different receiving beams to receive signals from multiple UEs simultaneously, or when a UE needs to perform different SL receiving operations simultaneously, it is necessary to resolve conflicts between different receiving beams.

[0045] To address this issue, this disclosure proposes a direct communication method and apparatus to resolve the beam conflict problem when a UE performs multiple receiving operations simultaneously or receives multiple SL signals corresponding to different beams.

[0046] The direct communication method and apparatus provided in this application will be described in detail below with reference to the accompanying drawings.

[0047] Figure 1 A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a user equipment (UE). In this disclosure, the user equipment (UE) includes, but is not limited to, smart terminal devices, cellular phones, wireless devices, handheld devices, mobile units, vehicles, and in-vehicle equipment.

[0048] In the embodiments of this disclosure, the solutions provided in this disclosure can be used for fifth-generation mobile communication technology (5G) and its subsequent communication technologies, such as fifth-generation mobile communication technology evolution (5G-advanced) and sixth-generation mobile communication technology (6G), and are not limited in this disclosure.

[0049] like Figure 1 As shown, the method may include the following steps.

[0050] S101, under the preset condition, use the preset receiving beam or select M receiving beams to perform direct SL receiving operation.

[0051] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0052] In other words, M can be the number of receiving beams used simultaneously by the UE during SL receiving operations. The term "simultaneously" does not limit the value of M; that is, M can be applied to this method as long as it is greater than or equal to 1. The specific value of M depends on the number of receiving operations in the same or different groups, which is not limited in this disclosure.

[0053] Furthermore, the default scenario refers to the UE using different receiving beams to receive multiple SL signals, or the UE needing to perform multiple different SL receiving operations simultaneously.

[0054] In the embodiments of this disclosure, depending on the specific scenario that meets the preset conditions, the UE can use a preset receiving beam to perform a direct SL receiving operation. For example, the UE can use the default beam configured by the base station to receive specific S-SSB or SL CSI-RS resources. The UE can also select M receiving beams to perform a direct SL receiving operation. For example, the UE can select no more than M receiving beams from N receiving beams to perform the corresponding SL receiving operation.

[0055] Therefore, in the embodiments of this disclosure, under a preset condition, the UE uses a preset receiving beam or selects M receiving beams to perform a direct SL receiving operation. The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE to perform the SL receiving operation at the same time. M is greater than or equal to 1. This takes into account how the UE determines the receiving beam to perform the direct SL receiving operation when it needs to perform SL receiving operations corresponding to different receiving beams, thereby realizing beam management support on the SL.

[0056] based on Figure 1 The embodiment shown, Figure 2 A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a UE. Figure 2 As shown, the method may include the following steps:

[0057] S201, under the preset condition, use the preset receiving beam or select M receiving beams to perform direct SL receiving operation.

[0058] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0059] Furthermore, the following embodiments provide further explanations regarding the determination of N receiving beams, preset conditions, SL receiving operations, and the number M. The following embodiments may be implemented partially or entirely according to specific application scenarios.

[0060] In some embodiments, the time-frequency resource sets of the reference signals associated with the N receiving beams are different, and the spatial receiving beam parameters of the time-frequency resource sets of the different reference signals are different.

[0061] The reference signal (RS) includes, but is not limited to, SSB (Synchronization Signal and PBCH block), CSI-RS, or uplink SRS (Sounding Reference Signal).

[0062] In other words, the difference between the N receiving beams lies in the fact that the QCL (Quasi Co Location) of the N receiving beams is associated with different time-frequency resource sets, i.e., RS set(s), and they do not have the same spatial receiving parameters for SL transmission.

[0063] In some embodiments, the preset conditions include at least one of the following: the UE needs to receive multiple SL channels or signals simultaneously, the multiple SL signals or channels may come from other UEs in different geographical locations, and therefore different SL channels or signals correspond to different receiving beams; the UE needs to receive the Physical Direct Control Channel (PSCCH) or Physical Direct Shared Channel (PSSCH) from different UEs in the same time unit; the UE needs to receive the Physical Direct Feedback Channel (PSFCH) from different UEs in the same time unit; the UE needs to perform multiple different types of SL receiving operations in one time unit, and the multiple different types of SL receiving operations correspond to different receiving beams.

[0064] In some embodiments, the SL receiving operation includes at least one of the following: PSCCH receiving, PSSCH receiving, Direct Sync Broadcast Block (S-SSB) receiving, PSFCH receiving, Positioning or Ranging Reference Signal receiving, Channel State Information Reference Signal (CSI-RS) receiving, Sensing, Channel Busy Rate (CBR) measurement, Channel Monitoring, Listen Before Transmit (LBT) monitoring.

[0065] In other words, the default scenario is that the UE needs to use N receiving beams simultaneously for SL reception, including the UE needing to receive N SL channels or signals simultaneously, and different SL channels or signals corresponding to different receiving beams.

[0066] Furthermore, the preset scenarios include, but are not limited to: the UE needing to receive FDM (Frequency Division Multiplexing) PSCCH / PSSCH (Physical Sidelink Control Channel) from different UEs in the same slot, or FDM / CDM (Code Division Multiplexing) PSFCH (Physical Sidelink Feedback Channel) from different UEs; the UE needing to perform multiple different types of SL reception operations within a slot, with each reception operation corresponding to a different reception beam; and combinations of the above two scenarios.

[0067] Furthermore, different types of SL reception include, but are not limited to: PSCCH / PSSCH reception, S-SSB reception, PSFCH reception, Sensing, CBR (Constant bitrate) measurement, etc.

[0068] In 5G application scenarios, the network devices mentioned above can be 5G Radio Access Network (NG-RAN) nodes, such as gNB or ng-eNB. gNB can be used for standalone networking, while ng-eNB can be used for backward compatibility with 4G networks to adapt to the application requirements of different core networks. The specific use cases depend on the application scenario and are not limited here.

[0069] The time units described in the embodiments of this disclosure may include slots, subframes, frames, subslots, OFDM symbols, etc., and are not limited thereto in this disclosure.

[0070] In summary, in the embodiments of this disclosure, under a preset condition, the UE uses a preset receiving beam or selects M receiving beams to perform a direct SL receiving operation. The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE to perform the SL receiving operation simultaneously, and M is greater than or equal to 1. This takes into account how the UE determines the receiving beam and which SL receiving operations to perform when it needs to perform SL receiving operations corresponding to different receiving beams, thereby realizing beam management support on the SL.

[0071] based on Figure 1 or Figure 2 The embodiment shown, Figure 3A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a UE. Figure 3 As shown, the method may include the following steps:

[0072] S301, under preset conditions, uses a preset receiving beam to perform direct SL receiving operation.

[0073] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0074] Furthermore, using a preset receiving beam for SL reception includes: using a predefined or preconfigured preset receiving beam for SL reception; or, receiving configuration information of the preset receiving beam sent by the network device and using the preset receiving beam for SL reception.

[0075] In other words, the UE uses a specific default receiving beam for reception, such as using an omnidirectional antenna by default, or the default beam is the beam that receives specific S-SSB or SL CSI-RS resources. The default receiving beam can be configured by the base station, predefined, or pre-configured by the UE.

[0076] Among them, pre-configured information is obtained, for example, by reading pre-configured data stored in the UE chip; pre-defined information is obtained, for example, by prior agreement of the protocol; and base station configuration is obtained, for example, by the UE receiving configuration information of the preset receiving beam sent by the network device.

[0077] In some embodiments, the time-frequency resource sets of the reference signals associated with the N receiving beams are different, and the spatial receiving beam parameters of the time-frequency resource sets of the different reference signals are different.

[0078] In some embodiments, the preset conditions include at least one of the following: the UE needs to receive multiple SL channels or signals simultaneously, and different SL channels or signals correspond to different receiving beams; the UE needs to receive Physical Direct Control Channel (PSCCH) or Physical Direct Shared Channel (PSSCH) from different UEs in the same time unit; the UE needs to receive Physical Direct Feedback Channel (PSFCH) from different UEs in the same time unit; the UE needs to perform multiple different types of SL receiving operations in one time unit, and the multiple different types of SL receiving operations correspond to different receiving beams.

[0079] In some embodiments, the SL receiving operation includes at least one of the following: PSCCH receiving, PSSCH receiving, Direct Sync Broadcast Block (S-SSB) receiving, PSFCH receiving, Positioning or Ranging Reference Signal receiving, Channel State Information Reference Signal (CSI-RS) receiving, Sensing, Channel Busy Rate (CBR) measurement, Channel Monitoring, Listen Before Transmit (LBT) monitoring.

[0080] In some embodiments, the method further includes: determining the value of M according to the protocol or configuration information carried in the downlink control signaling sent by the network device, or determining the value of M according to the number of receiving beams that can be used simultaneously supported by the UE capability.

[0081] In some embodiments, the method further includes: sending uplink control signaling to a network device, the uplink control signaling including M, and / or sending direct connection control signaling to other UEs, the direct connection control signaling including M.

[0082] For a detailed explanation of the above embodiments, please refer to [link / reference]. Figure 1 The illustrated embodiments will not be described in detail here.

[0083] In summary, according to the direct communication method provided in this disclosure, under preset conditions, the UE uses a preset receiving beam to perform direct SL receiving operations. The preset conditions indicate that the SL receiving operation corresponds to N different receiving beams, and N is greater than M, where M is the number of receiving beams used by the UE to perform SL receiving operations simultaneously. M is greater than or equal to 1. This takes into account that when SL receiving operations corresponding to different receiving beams need to be performed, the UE uses a preset receiving beam to perform direct SL receiving operations, thereby enabling beam management on the SL and avoiding receiving beam conflicts when the SL performs multiple receiving operations simultaneously or receives multiple SL signals corresponding to different beams.

[0084] It should be noted that the following Figure 3 , Figure 4 , Figure 5 The example is Figure 1 or Figure 2 In the embodiment, under preset conditions, the further limitation of selecting M receiving beams for SL receiving operation can be based on... Figure 3 , Figure 4 , Figure 5 The method in the embodiment determines the selection order of the M SL transmissions.

[0085] based on Figure 1 or Figure 2 The embodiment shown, Figure 4 A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a UE. Figure 4 As shown, the method may include the following steps:

[0086] S401, under preset conditions, determines the priority of SL reception operations corresponding to different reception beams.

[0087] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0088] Furthermore, determining the priority of SL reception operations corresponding to different reception beams includes at least one of the following:

[0089] When the receiving beam receives PSCCH / PSSCH transmissions, the priority of receiving PSCCH / PSSCH transmissions is determined according to the priority field in the first-stage direct link control information, or according to the logical channel contained in the MAC PDU and the highest priority field in the MAC CE.

[0090] When the receiving beam corresponds to receiving PSFCH transmission, the priority of receiving PSFCH transmission is determined according to the priority of PSCCH / PSSCH corresponding to PSFCH; when the receiving beam corresponds to receiving S-SSB transmission, the priority of receiving S-SSB transmission is determined according to the configuration information carried in the downlink control signaling sent by the network device, which is predefined, preconfigured, or sent by the network device.

[0091] When the receiving beam receives a specific SL transmission, the priority of receiving the specific SL transmission is determined according to the configuration information carried in the downlink control signaling sent by the network device, which is predefined, preconfigured, or sent by the network device. The specific SL transmission received includes at least one of the following: receiving positioning or ranging reference signals, receiving CSI-RS.

[0092] When the receiving beam corresponds to a specific SL receiving operation, the priority of executing the specific SL receiving operation is determined according to the configuration information carried in the downlink control signaling sent by the network device, which is predefined, preconfigured, or sent by the network device. The specific SL receiving operation includes at least one of the following: sensing, CBR measurement, channel monitoring, and LBT listening.

[0093] When the same receiving beam corresponds to multiple different SL receiving operations, the priority of the SL receiving operation corresponding to the receiving beam is determined according to the highest priority among the multiple SL receiving operations.

[0094] For example, for PSCCH / PSSCH transmissions, the priority is determined according to the priority field in the 1st stage SCI, or the highest priority in the logical channel and MAC CE contained in the MAC PDU; for PSFCH transmissions, the priority is determined according to the priority of its corresponding PSCCH / PSSCH; for S-SSB transmissions, the priority is determined according to the (pre)configuration information; for operations such as sensing and CBR measurement, the priority can also be determined according to the (pre)configuration information, or it can be predefined as the lowest priority.

[0095] S402, selects M receiving beams from N receiving beams in descending order of priority for SL receiving operation.

[0096] In other words, based on step 401, the priority of SL transmission is determined, and the selection order of the M SL transmissions is determined according to the priority of SL transmission. That is, among the N receiving beams, the M high-priority receiving beams are preferentially selected for SL reception operation. In some embodiments, the receiving beam for SL reception operation by the UE can cover the M receiving beams. For example, the gain of the receiving beam in a specific direction (e.g., the peak direction) of any one of the M receiving beams is not less than a specific value; or the XdB beamwidth angle of any one of the M receiving beams is located within the YdB beamwidth angle of the receiving beam, etc.

[0097] In some embodiments, the time-frequency resource sets of the reference signals associated with the N receiving beams are different, and the spatial receiving beam parameters of the time-frequency resource sets of the different reference signals are different.

[0098] In some embodiments, the preset conditions include at least one of the following: the UE needs to receive multiple SL channels or signals simultaneously, and different SL channels or signals correspond to different receiving beams; the UE needs to receive Physical Direct Control Channel (PSCCH) or Physical Direct Shared Channel (PSSCH) from different UEs in the same time unit; the UE needs to receive Physical Direct Feedback Channel (PSFCH) from different UEs in the same time unit; the UE needs to perform multiple different types of SL receiving operations in one time unit, and the multiple different types of SL receiving operations correspond to different receiving beams.

[0099] In some embodiments, the SL receiving operation includes at least one of the following: PSCCH receiving, PSSCH receiving, Direct Sync Broadcast Block (S-SSB) receiving, PSFCH receiving, Positioning or Ranging Reference Signal receiving, Channel State Information Reference Signal (CSI-RS) receiving, Sensing, Channel Busy Rate (CBR) measurement, Channel Monitoring, Listen Before Transmit (LBT) monitoring.

[0100] In some embodiments, the method further includes: determining the value of M according to the protocol or configuration information carried in the downlink control signaling sent by the network device, or determining the value of M according to the number of receiving beams that can be used simultaneously supported by the UE capability.

[0101] In some embodiments, the method further includes: sending uplink control signaling to a network device, the uplink control signaling including M, and / or sending direct connection control signaling to other UEs, the direct connection control signaling including M.

[0102] For a detailed explanation of the above embodiments, please refer to [link / reference]. Figure 1 The illustrated embodiments will not be described in detail here.

[0103] In summary, based on the direct communication method provided in this disclosure, when it is necessary to perform SL receiving operations corresponding to different receiving beams, the UE determines the priority of the SL receiving operations corresponding to different receiving beams, and selects the receiving beams to perform SL receiving operations in descending order of priority, thereby enabling beam management on the SL and avoiding receiving beam conflicts when the SL performs multiple receiving operations at the same time or receives multiple SL signals corresponding to different beams.

[0104] based on Figure 1 or Figure 2 The embodiment shown, Figure 5 A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a UE. Figure 5 As shown, the method may include the following steps:

[0105] S501, under the default condition, selects M receiving beams from N receiving beams to perform SL receiving operation according to the type of SL receiving operation.

[0106] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0107] In the embodiments of this disclosure, the selection order of the M SL transmissions is determined based on the type of SL reception operation, i.e., the UE's reception behavior. For example, for N SL transmissions that need to be received simultaneously, the M beams are selected in the following order: first, the beams for PSCCH / PSSCH / PSFCH reception are selected; second, the beams for sensing reception are selected; and third, the beams for CBR measurement are selected. This disclosure does not limit the selection order of the receiving beams for different types of SL reception operations.

[0108] In some embodiments, the time-frequency resource sets of the reference signals associated with the N receiving beams are different, and the spatial receiving beam parameters of the time-frequency resource sets of the different reference signals are different.

[0109] In some embodiments, the preset conditions include at least one of the following: the UE needs to receive multiple SL channels or signals simultaneously, and different SL channels or signals correspond to different receiving beams; the UE needs to receive Physical Direct Control Channel (PSCCH) or Physical Direct Shared Channel (PSSCH) from different UEs in the same time unit; the UE needs to receive Physical Direct Feedback Channel (PSFCH) from different UEs in the same time unit; the UE needs to perform multiple different types of SL receiving operations in one time unit, and the multiple different types of SL receiving operations correspond to different receiving beams.

[0111] In some embodiments, the method further includes: determining the value of M according to the protocol or configuration information carried in the downlink control signaling sent by the network device, or determining the value of M according to the number of receiving beams that can be used simultaneously supported by the UE capability.

[0113] For a detailed explanation of the above embodiments, please refer to [link / reference]. Figure 1 The illustrated embodiments will not be described in detail here.

[0114] In summary, according to the direct communication method provided in this disclosure, under a preset condition, the UE selects M receiving beams from N receiving beams to perform SL receiving operations based on the type of SL receiving operation. The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE to perform SL receiving operations simultaneously, and M is greater than or equal to 1. This takes into account that when it is necessary to perform SL receiving operations corresponding to different receiving beams, the UE selects receiving beams to perform direct SL receiving operations based on the type of SL receiving operation, thereby enabling beam management on the SL and avoiding receiving beam conflicts when the SL performs multiple receiving operations simultaneously or receives multiple SL signals corresponding to different beams.

[0115] based on Figure 1 or Figure 2 The embodiment shown, Figure 6 A flowchart illustrating a direct communication method according to an embodiment of this disclosure is shown. This method can be executed by a UE. Figure 6 As shown, the method may include the following steps:

[0116] S601, under the preset condition, group the N receiving beams and determine the receiving beam combination supported by the UE.

[0117] The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, and N is greater than M. M is the number of receiving beams used by the UE at the same time to perform the SL receiving operation, and M is greater than or equal to 1.

[0118] In the embodiments of this disclosure, the selection order of M SL transmissions is determined according to the possible receive beam combinations supported by the UE. The specific value of M is determined according to the number of SL receive operations in the same or different groups, and this disclosure does not limit this.

[0119] The following are two methods for grouping N received beams as shown in the embodiments of this disclosure:

[0120] In one grouping method, N receiving beams are grouped, wherein the receiving beams in different receiving beam combinations support simultaneous SL receiving operations; M receiving beams belonging to different receiving beam combinations are selected for SL receiving operations.

[0121] In other words, receiving beams in the same group cannot be used simultaneously, while receiving beams in different groups can be used simultaneously. The UE selects a beam to use within different receiving beam groups.

[0122] Furthermore, the N receive beams can be grouped according to the antenna panels to which they belong in order to determine the receive beam combinations supported by the UE, wherein receive beams belonging to the same antenna panel are included in the same receive beam combination.

[0123] In other words, the receiving beams belonging to the same antenna panel are grouped together according to the antenna panel to which they belong.

[0124] Furthermore, selecting M receiving beams belonging to different receiving beam combinations for SL receiving operation includes: selecting the receiving beam with the highest priority corresponding to the SL receiving operation from each receiving beam combination for SL receiving operation.

[0125] In other words, the UE selects the highest priority beam within each different receive beam group, and receive beams within different receive beam groups can be used simultaneously.

[0126] In another grouping method, grouping N receive beams to determine the receive beam combinations supported by the UE includes: grouping the N receive beams, wherein the receive beams in the same receive beam combination support simultaneous SL receive operation; and selecting M receive beams belonging to the same receive beam combination to perform SL receive operation.

[0127] In other words, different groups of receiving beams cannot be used simultaneously, while receiving beams of the same group can be used simultaneously. The UE selects a beam to use within the same receiving beam group.

[0128] Furthermore, the N receiving beams can be grouped according to the antenna panels to which they belong in order to determine the receiving beam combinations supported by the UE, wherein receiving beams belonging to different antenna panels are included in the same receiving beam combination.

[0129] In other words, the receiving beams belonging to different antenna panels are grouped together.

[0130] Furthermore, selecting M receiving beams belonging to the same receiving beam combination for SL receiving operation includes: determining the beam combination containing the receiving beam with the highest priority corresponding to the SL receiving operation; and determining M receiving beams from the beam combination for SL receiving operation.

[0131] In other words, the UE selects the highest priority beam within the same receiving beam group, and receiving beams within the same receiving beam group can be used simultaneously.

[0132] It should be understood that, Figure 4 The SL priority mentioned above is used to determine the priority of each SL transmission within the same type of SL transmission. Figure 5 The SL priority mentioned above is a priority assigned to different types of SL transmissions, while Figure 6 The illustrated embodiment groups the receiving beams, and within each receiving beam combination, it can be based on... Figure 4 or Figure 5The SL transmission priority selects the beam with the highest priority for use.

[0133] It is understood that the two methods of grouping the received beams disclosed herein may be used to group the beams according to the antenna panels to which the beams belong, or other grouping methods may be used. This disclosure does not limit this. After the two grouping methods disclosed herein, M SLs are selected for transmission. Specifically, the selection is based on the priority order of the received beams in different / same received beam groups, or other methods may be used to select M SLs for transmission. This disclosure does not limit this.

[0134] For example, when grouping by enumeration, the UE enumerates the receive beam groups that can be used simultaneously, and selects one receive beam group for reception according to a predetermined principle. The predetermined principle is, for example, that the receive beam group can support the most receive beams among N receive beams, or that the receive beam group can support the highest priority SL channel / signal / reception operation receive beam among N receive beams.

[0135] In summary, based on the direct communication method provided in this disclosure, when it is necessary to perform SL receiving operations corresponding to different receiving beams, the UE groups the N receiving beams to determine the receiving beam combination supported by the UE; according to the receiving beam combination supported by the UE, M receiving beams are selected from the N receiving beams to perform SL receiving operations, thereby realizing beam management on the SL and avoiding receiving beam conflicts when the SL performs multiple receiving operations simultaneously or receives multiple SL signals corresponding to different beams.
