[0002] At present, the deployment of C-V2X (Cellular Vehicle-to-Everything) is mainly in the sub-6G frequency band (FR1 (Frequency Range 1) frequency band), however, with the development of C-V2X, the sub-6G frequency band cannot meet the requirements of future vehicle networking for ultra-high throughput, ultra-low latency and ultra-high reliability. The millimeter wave 30-300GHz frequency band (FR2 (Frequency Range 2) frequency band) can improve the system performance by up to several orders of magnitude, and has great application potential for vehicle networking. Vehicle networking millimeter wave communication technology can solve the contradiction between the limited spectrum resources of the sub-6G frequency band and the massive data required by future automatic driving.

[0054] In order to make the above objectives, characteristics and advantages of the present application more apparent, further specific embodiments will be described in detail with reference to the accompanying drawings and specific embodiments.

[0055] Referring to Figure 1 , a step flow chart of a beam management method of a sidelink provided by an embodiment of the present application is shown, which can be applied to a first user equipment. As Figure 1 indicated, the beam management method of the sidelink can specifically include:

[0056] Step 101: sending scheduling request signaling for indicating scheduling of a beam sweeping channel to a base station.

[0057] Embodiments of the present application can be applied to a first user equipment, i.e., the execution subject is the first user equipment.

[0058] When the first user equipment and the second user equipment are initially beam paired, the first user equipment can send scheduling request signaling for indicating a beam sweeping channel to the base station. Specifically, the first user equipment can be a user equipment within the network coverage range of the base station, and the first user equipment can send scheduling request signaling for indicating scheduling of a beam sweeping channel to the base station through an uplink transmission message, for requesting the base station to schedule resources for the first user equipment to send the beam sweeping channel, which can be used for beam sweeping.

[0059] In this example, the scheduling request signaling can include at least one of resource occupation information of a beam sweeping channel resource set, beam information, propagation times information, bandwidth information, unicast service information, etc.

[0060] It can be understood that the scheduling request signaling can include, but is not limited to, related information of the beam sweeping channel resource set, related information of the beam sweeping channel resource, related information of the beam sweeping channel, etc., which is not limited in this embodiment.

[0061] The resource occupation information of the beam sweeping channel resource set can include time-frequency resource information of the beam sweeping channel resource set, a beam sweeping channel burst set, an interval between beam sweeping channels, etc., as Figure 5 indicated.

[0062] The beam information can include beam index information, beam direction, beam number and beam pattern, etc.

[0063] The propagation times information refers to the number of repeated transmissions of each beam sweeping channel or beam sweeping channel resource set.

[0064] The bandwidth information refers to the frequency bandwidth range allocated to the beam sweeping channel resource set.

[0065] The unicast service information refers to information of a point-to-point communication service provided for a single user or device in the beam sweeping and communication system.

[0066] Of course, the scheduling request signaling can include at least one of the above contents, and can also include time interval information of the beam sweeping channel resource set, etc., and the present embodiment is not limited in this regard.

[0067] Step 102: determining resource location information of the beam sweeping channel resource set according to pre-configuration signaling and / or base station resource scheduling information returned by the base station based on the scheduling request signaling.

[0068] The resource location information refers to information of defining and identifying specific locations of channel resources used in the beam sweeping process in the time domain and the frequency domain in the communication system, and can include specific location information of the beam sweeping in the time domain and the frequency domain, and key information such as beam index, scheduling request signaling, etc. associated with the location information.

[0069] The present application can determine the resource location information of the beam sweeping channel resource set based on the pre-configuration signaling and / or the base station resource scheduling information returned by the base station based on the scheduling request signaling. The pre-configuration signaling can be a configuration completed by the first user equipment before sending the scheduling request signaling.

[0070] In the present example, the pre-configuration signaling can include RRC (Radio Resource Control) signaling, and the base station resource scheduling information can include DCI (Downlink Control Information) signaling.

[0071] The DCI signaling can include resource pool ID, time domain resource offset, time-frequency resource allocation information, power transmission information, destination ID, activation or release indication information, beam sweeping channel reference signal resource configuration index (RS (Reference Signal) resource ID or RS resource ID+RS resource set ID), time difference information, PUCCH (Physical Uplink Control Channel) resource location information / PUSCH (Physical Uplink Shared Channel) resource location information, etc.

[0072] The RRC signaling can include a CG (Configured Grant) configuration index, a resource pool ID, a time domain resource offset, time-frequency resource allocation information, periodicity information, a beam sweeping channel reference signal resource configuration index, PUCCH resource location information / PUSCH resource location information, and the like.

[0073] The manner of determining the resource location information of the beam sweeping channel resource set according to the preconfigured signaling and / or base station resource scheduling information can include any one of the following manners:

[0074] 1. Receiving DCI signaling sent by the base station, and determining the resource location information of the beam sweeping channel resource set based on the DCI signaling.

[0075] In this example, dynamic scheduling is mainly for aperiodic transmission, and the transmission resource is scheduled and indicated by DCI. After receiving the DCI signaling sent by the base station, the first user equipment can determine the beam sweeping channel transmission resource based on the decoding information of the DCI signaling. As shown in Figure 8 The Uu can be an interface for transmitting user data and control signaling between the UE1 (i.e., the first user equipment) and the base station. The base station can send a downlink transmission message to the UE1 through the Uu, and the downlink transmission message contains the DCI signaling. The time gap represents the time interval, and the RS resource group is a group of specific communication resources (such as time-frequency resources, beam resources, etc.) for beam sweeping. The DCI signaling can contain information directly indicating the resource location of the beam sweeping channel resource set, such as the index of the resource block, the location of the subcarrier, etc. By decoding the DCI signaling, the resource location information of the beam sweeping channel resource set can be determined.

[0076] It can be understood that before the base station sends the DCI signaling to the first user equipment, the base station can first establish an RRC connection with the first user equipment. Specifically, the first user equipment can send an RRC connection request message to the base station to request to establish an RRC connection, and the base station responds to the first user equipment through RRC signaling (different from the preconfigured RRC signaling), which contains the wireless resource information configured for the UE. Then, the base station can return the DCI signaling to the first user equipment according to the scheduling request signaling.

[0077] 2. Determining the resource location information of the beam sweeping channel resource set according to the RRC signaling.

[0078] In this example, before the first user equipment sends the scheduling request signaling, the first user equipment has been preconfigured with RRC signaling, which can be parsed to obtain the above-mentioned parameters contained therein, and the resource location information of the beam sweeping channel resource set can be determined according to the above-mentioned parameters. As shown in Figure 9As shown, the base station can send an RRC configuration message to UE1 through the Uu interface. After receiving the RRC configuration, UE1 can determine the resource location information of the beam scanning channel resource set based on the parameters in the parsed RRC configuration message.

[0079] 3. Obtain the DCI signaling sent by the base station, and determine the resource location information of the beam scanning channel resource set based on the RRC signaling and the DCI signaling.

[0080] When DCI signaling is received from the base station based on scheduling request signaling, the resource location information of the beam scanning channel resource set can be determined based on pre-configured RRC signaling and DCI signaling. This process is for periodic transmissions, and both the scheduling time domain and dynamic scheduling type can be indicated by DCI signaling. RRC signaling is responsible for configuring the CG configuration index, period, etc., while specific transmission parameters are activated and deactivated through DCI signaling. Figure 10 As shown, when UE1 receives a configuration activation signaling DCI, it performs periodic beam scanning channel transmission according to the RRC configuration and the DCI signaling.

[0081] Step 103: Transmit the beam scanning channel on the resource location information of the beam scanning channel resource set so that the second user equipment can obtain a beam report by measuring the beam scanning channel.

[0082] The beam scanning channel may include reference signals such as the Beam Measurement Reference Signal (BMRS), the Channel State Information-Reference Signal (CSI-RS), and the Demodulation Reference Signal (DMRS).

[0083] The channel structure of a beam scanning channel includes at least one of the following:

[0084] 1. The RS (reference signal) in a slot all have the same (e.g., Figure 6 (as shown in the left figure) or different (such as) Figure 6(As shown in the right figure) beam direction transmission. In the left figure, the beam of the transmit control channel can be the same as or cover the beam direction of the transmit reference signal. In the right figure, the RS multiplexing method is TDM (Time Division Multiplexing), where symbols within a slot are divided into different RS resources in the time domain. Different RS resources can transmit with different beam directions in the time domain. In this case, the beam of the transmit control channel can be the same as or cover the beam direction of the transmit reference signal.

[0085] 2. Mini-slot structure: In a slot, the control channel and RS are multiplexed using TDM (Time Division Multiplexing). The RS multiplexing method is also TDM. In the time domain, symbols within a slot are divided into different RS resources, which can be transmitted in different beam directions. In this case, the beam of the transmitted control channel can be in the same direction as the corresponding transmitted reference signal, and the beam of the transmitted control channel can be the same as or wider than the beam of its indicated reference signal. For example... Figure 7 As shown.

[0086] exist Figure 7 The multiplexing method for the control channel and RS is TDM. Of course, in practical applications, the multiplexing method can also be TDM+FDM (Frequency Division Multiplexing) or FDM (not shown in the figure). The RS can be a comb-like mapping structure. The number of time-domain symbols and / or the starting symbol position or occupied time-domain symbol position pattern information of the RS in the slot can be indicated by display, or configured or pre-configured by higher-layer parameters. It is also possible to limit the frequency domain of the beam scanning channel to occupy the entire frequency domain bandwidth of the resource pool, etc.

[0087] In the second channel structure described above, the first OFDM (Orthogonal Frequency Division Multiplexing) symbol in the time domain of RS carrying different beam directions can be used for AGC (Automatic Gain Control) processing. Specific implementation methods include at least one of the following:

[0088] (1) The first OFDM symbol is obtained by repeatedly mapping the RE (Resource Element) on the second OFDM symbol.

[0089] (2) The first OFDM symbol multiplexing mapping is dedicated to AGC-RS (Automatic Gain Control Reference Signal).

[0090] The reference signal configuration information includes at least one of the following:

[0091] 1. Time-domain configuration information of the reference signal, including at least one of the following: time-domain pattern information of the reference signal, time-domain start symbol position information of the reference signal, and time-domain symbol number information of the reference signal.

[0092] 2. Frequency domain configuration information of the reference signal, including at least one of the following: frequency domain pattern information of the reference signal, starting PRB (Physical Resource Block) position information of the reference signal frequency domain, starting sub-channel position information of the reference signal frequency domain, number of PRBs and / or number of sub-channels occupied by the reference signal frequency domain, and frequency domain shift information of the reference signal (i.e., the number of PRBs offset relative to the frequency domain reference point).

[0093] 3. Number and sequence of reference signal ports.

[0094] After determining the resource location information of the beam scanning channel resource set based on the pre-configured signaling and / or the base station resource scheduling information returned by the base station based on the scheduling request signaling, the beam scanning channel can be transmitted on the resource location information of the beam scanning channel resource set, so that the second user equipment can obtain a beam report by measuring the beam scanning channel. The beam report can be a report obtained by the second user equipment periodically performing beam scanning measurements on the beam scanning channel.

[0095] The beam scanning channel is transmitted on the resource location information of the beam scanning channel resource set so that after the second user equipment obtains a beam report by measuring the beam scanning channel, step 104 or step 105 is executed.

[0096] Step 104: Based on the beam report, determine the target beam pair for communication with the second user equipment, generate beam indication information based on the target beam pair, and send the beam indication information.

[0097] After transmitting the beam scanning channel on the resource location information of the beam scanning channel resource set, the beam report obtained by the second user equipment from the beam scanning channel measurement can be acquired. In this example, the first user equipment can acquire the beam report of the second user equipment in the following two ways:

[0098] 1. Obtain the beam report obtained by the second user equipment from beam scanning the beam scanning channel resource set at the SL resource location.

[0099] In this embodiment, the SL resource location information can be the resource location information that the second user equipment sends an uplink resource request message to the base station, and the base station returns to the first user equipment in response to the uplink resource request message.

[0100] The method for obtaining this beam report can be as follows: Figure 3 As shown, in Figure 3 In this diagram, UE1 is the first user equipment, UE2 is the second user equipment, and SR (Scheduling Request) and BSR (Buffer Status Report) are used. The beam report acquisition method is as follows: When the second user equipment sends a beam report to the first user equipment, it can send an SR / BSR message to the base station to request SL resource location information. The base station can then send the SL resource location information to both the first and second user equipment via downlink transmission messages. Furthermore, the second user equipment can then send a beam report to the first user equipment using the SL resource location information. The first user equipment can then obtain the beam report sent by the second user equipment using this SL resource location information.

[0101] 2. Obtain the beam report sent by the second user equipment through the resource location information corresponding to the beam report.

[0102] In this embodiment, the resource location information can be determined by the second user equipment based on the beam report reserved resources corresponding to the beam scanning channel and the association between the beam report and the beam scanning channel. The beam report reserved resources can be the resources reserved by the base station when configuring beam scanning channel resources for the first user equipment.

[0103] The method for obtaining this beam report can be as follows: Figure 2 As shown, when configuring beam scanning channel resources for UE1, the base station reserves resources for beam reports corresponding to the beam scanning channel. It determines the resource location of the beam report through the association (configuration or pre-configuration) between the beam report and the beam scanning channel. Specifically, when the base station configures beam scanning channel resources for UE1 via DCI signaling or RRC signaling, it simultaneously instructs to reserve resources for beam reports corresponding to the beam scanning channel. Furthermore, UE2 can send beam reports using the resource location information corresponding to the beam reports, and UE1 can receive beam reports sent by UE2.

[0104] After the first user equipment receives the beam report from the second user equipment, it can determine the target beam pair for communication with the second user equipment based on the beam report. Specifically, the first user equipment can determine the target beam pair for communication with the second user equipment based on the RSRP (Reference Signal Received Power) value of the beam pair contained in the beam report. The method for determining the target beam pair can include either of the following two methods:

[0105] 1. Obtain the beam pair with the largest RSRP measurement value among all beam pairs in the beam report, and use it as the target beam pair.

[0106] 2. Obtain beam pairs from the beam report whose RSRP measurements are greater than a threshold (configured or pre-configured by higher-layer parameters). If there are multiple beam pairs, one can be randomly selected as the target beam pair, or the beam pair with the largest measurement value can be selected as the target beam pair. Of course, if no beam pair greater than the threshold exists, the beam pair with the largest measurement value among all RSRP measurements can be selected as the target beam pair, or the second user equipment can be informed via downlink transmission that there are no selectable beam pairs in this beam report.

[0107] After determining the target beam pair for communication with the second user equipment, beam indication information can be generated based on the target beam pair and then sent. This beam indication information may include: the communication beam pair selected by the first user equipment (i.e., the target beam pair) and the identification information of the second user equipment.

[0108] The methods for transmitting beam indication information can include:

[0109] First, the beam indication information generated based on the target beam pair is sent to the base station, and the base station then sends the beam indication information to the second user equipment.

[0110] In one specific implementation of this embodiment, the first user equipment can send beam indication information to the base station. Specifically, when the base station configures beam scanning channel resources for the first user equipment via DCI signaling or RRC signaling, it simultaneously indicates the uplink resources allocated to the first user equipment for transmitting beam indication. The time domain location of this resource is after one or more RS resource sets in the DCI indication / configuration grant period.

[0111] For dynamically scheduled resource allocation, the base station indicates one uplink transmission resource in the DCI for reporting beam indication to the network. For configuration-authorized resource allocation, one uplink resource is allocated in each SL configuration authorization period for reporting beam indication information for the current period to the base station.

[0112] After receiving the beam indication information sent by the first user equipment, the base station can then send the beam indication information to the second user equipment.

[0113] 2. The beam indication information generated based on the target beam pair is sent to the base station, and the location information of the SL resource scheduled by the base station is obtained. The beam indication information is then sent to the second user equipment based on the SL resource location information.

[0114] In another specific implementation of this embodiment, the first user equipment can send beam indication information to the base station, obtain the SL resource location information scheduled by the base station, and send the beam indication information to the second user equipment based on the SL resource location information. Specifically, the bearer method for the first user equipment to send the beam indication to the second user equipment can be: after receiving the beam indication sent by the first user equipment, the base station schedules SL resources for the first user equipment according to the time-frequency resource size information of the beam indication information, for the first user equipment to send the beam indication to the second user equipment. This is activated by a downlink transmission message containing DCI, such as... Figure 4 As shown, the base station can allocate resources for UE1 to send beam indications to UE2 by sending DCI to UE1.

[0115] The implementation process can be described as follows: Figure 11 As shown, after UE2 completes the beam scanning phase, it can send a beam report to UE1, and UE2 waits for beam indication from UE1. After UE1 determines the target beam pair for communication, it generates a beam indication and sends it to UE2 (the sending method is described in the two methods above). After receiving the beam indication, UE2 completes the beam pairing process. At the same time, it can set the latency bound (configured by higher layer parameters or pre-configured). That is, within the time T = latency bound after sending the beam report, UE2 performs beam scanning with the receiving beam selected by UE2 until it receives beam indication information from UE1.

[0116] In a preferred embodiment of this application, the base station can schedule multiple time-frequency resources for beam indications for the first user equipment to improve the success rate of the second user equipment receiving beam indications sent from the first user equipment.

[0117] Step 105: Receive beam indication information sent by the base station. The beam indication information sent by the base station is the beam indication information generated by the base station based on the target beam pair for communication between the first user equipment and the second user equipment, which is determined by the base station according to the beam report.

[0118] In this embodiment, after the second user equipment (UE) obtains a beam report by measuring the beam scanning channel, it can send the beam report to the base station (at this time, the second UE is within the network coverage area of ​​the base station) so that the base station can determine the target beam pair based on the beam report. Specifically, the base station selects a communication beam pair for the first and second UEs according to at least one of the following methods: 1. Obtain the beam pair with the largest measured value among all RSRP measurements in the beam report as the target beam pair. 2. Obtain beam pairs with RSRP measurements greater than a threshold (configured or pre-configured by higher-layer parameters) in the beam report. If there are multiple such beam pairs, one pair can be randomly selected, or the beam pair with the largest measured value can be selected. If there is no beam pair greater than the threshold, the beam pair with the largest measured value among all RSRP measurements is obtained as the target beam pair, or the second UE is informed via downlink transmission that there is no selectable beam pair in this beam report.

[0119] Then, the base station can generate beam indication information based on the determined target beam pair. This beam indication information may include: the target beam pair selected by the base station and the identification information of the second user equipment. Subsequently, the base station can send the beam indication information to the first user equipment.

[0120] The beam management method for a direct link provided in this application embodiment sends a scheduling request signaling to the base station to indicate beam scanning channel scheduling. Based on pre-configured signaling and / or base station resource scheduling information returned by the base station based on the scheduling request signaling, the resource location information of the beam scanning channel resource set is determined. A beam scanning channel is transmitted on the resource location information of the beam scanning channel resource set, enabling the second user equipment to obtain a beam report by measuring the beam scanning channel. Based on the beam report, a target beam pair for communication with the second user equipment is determined, and beam indication information is generated and transmitted based on the target beam pair. The beam indication information sent by the base station is received; the beam indication information sent by the base station is the beam indication information generated by the base station based on the target beam pair for communication between the first and second user equipment determined by the base station according to the beam report. In this application embodiment, the UE, through signaling interaction with the base station, can assist two UEs in completing beam pair matching, which is beneficial for beam coordination between UEs. Meanwhile, within the coverage area, the base station can make beam selection decisions to coordinate different communication beam pairs between UEs within the coverage area and avoid beam collisions.

[0121] Reference Figure 12 This diagram illustrates a flowchart of a beam management method for a through-link according to an embodiment of this application. This method can be applied to a second user equipment. Figure 12 As shown, the beam management method for this direct link may specifically include:

[0122] Step 1201: Measure the beam scanning channel and obtain a beam report.

[0123] The embodiments of this application can be applied to a second user equipment, that is, the execution subject is a second user equipment.

[0124] Based on the description of the above embodiments, after the first user equipment transmits the beam scanning channel according to the resource location information of the determined beam scanning channel resource set, the second user equipment can measure the beam scanning channel to obtain a beam report. In this example, the measurement process of the beam scanning channel may include the evaluation of parameters such as Received Signal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR), and Reference Signal Received Power (RSRP). Through these measurements, the second user equipment can identify which beam directions provide the best communication quality.

[0125] Step 1202: Send the beam report to the first user equipment or the base station, so that the first user equipment or the base station can determine the target beam pair for communication between the first user equipment and the second user equipment based on the beam report, and generate beam indication information based on the target beam pair.

[0126] After measuring the beam scanning channel and obtaining the beam report, the second user equipment can send the beam report to the first user equipment or to the base station. Specifically, when the second user equipment is within the network coverage area of ​​the base station, it can send the beam report to either the base station or the first user equipment. When the second user equipment is not within the network coverage area of ​​the base station, it can send the beam report to the first user equipment.

[0127] In this example, the beam report can be sent to the first user equipment in either of the following two ways:

[0128] 1. Based on the reserved resources for beam reports corresponding to the beam scanning channel and the correlation between beam reports and beam scanning channels, determine the resource location information corresponding to the beam report. The reserved resources for beam reports can be resources reserved by the base station when configuring beam scanning channel resources for the first user equipment. The second user equipment can then send the beam report to the first user equipment based on this resource location information.

[0129] like Figure 13As shown, when configuring beam scanning channel resources for UE1, the base station reserves resources for beam reports corresponding to the beam scanning channel and determines the resource location of the beam reports through the association relationship (configuration or pre-configuration) between the beam reports and the beam scanning channel. After completing the beam scanning measurement phase, UE2 can send the beam reports to UE1 according to the determined resource location of the beam reports.

[0130] 2. The second user equipment can send an uplink resource request message to the base station to obtain the SL resource location information returned by the base station in response to the uplink resource request information, and send the beam report to the first user equipment based on the SL resource location information.

[0131] like Figure 14 As shown, UE2 sends an SR / BSR to the base station, requesting SL new transmission resources for sending beam reports to UE1. The base station then uses DCI to indicate the scheduled beam report resources to UE1 and UE2.

[0132] Understandably, the second scenario described above only applies to situations where UE2 is within the network coverage area of ​​the base station.

[0133] When the second user equipment (UE) sends a beam report to the base station, it can first send an uplink resource request (UPR) to the base station. The base station then responds to the UER's UER by returning uplink resources. The UER can then send the beam report to the base station based on the returned uplink resources. Figure 15 As shown, the beam report resource is obtained as follows: UE2 sends an SR / BSR to the base station to request uplink resources for sending beam reports to the base station. The base station indicates the scheduled beam report resource to UE2 via DCI. UE2 then sends the beam report to the Uu interface using this beam report resource, and the Uu interface then forwards the beam report to the base station.

[0134] After the beam report is sent to the first user equipment or base station, the first user equipment or base station can determine the target beam pair for communication between the first user equipment and the second user equipment based on the beam report, and generate beam indication information based on the target beam pair.

[0135] The selection process for the target beam pair can be as follows: 1. Select the beam pair with the largest RSRP measurement value among all RSRP measurements in the beam report as the target beam pair. 2. Select the beam pairs with RSRP measurement values ​​greater than the threshold (high-level parameter configuration or pre-configuration) in the beam report. If there are multiple such beam pairs, one pair can be randomly selected as the target beam pair, or the beam pair with the largest measurement value among the multiple beam pairs can be selected as the target beam pair.

[0136] Step 1203: Receive the beam indication information sent by the first user equipment or the base station.

[0137] After the first user equipment or base station receives the beam report sent by the second user equipment, determines the target beam pair based on the beam report, and generates beam indication information, the first user equipment or base station may send the beam indication information to the second user equipment.

[0138] The method of receiving the beam indication information sent by the first user equipment may include either of the following two methods:

[0139] 1. Receive beam indication information sent by the first user equipment through the base station.

[0140] In this example, after the first user equipment generates beam indication information, it can send the beam indication information to the base station, which then forwards it to the second user equipment. Figure 16 As shown, after generating the beam indication, UE1 can send the beam indication to the base station through the Uu interface. The base station can send the downlink transmission message carrying beam pair information to UE2. UE2 receives the beam indication and completes the beam pairing of the initial beam.

[0141] 2. Receive the beam indication information sent by the first user equipment through the SL resource location information, where the SL resource location information is the resource location information scheduled by the base station for the first user equipment.

[0142] In this example, the base station can schedule SL resource location information for the first user equipment, and then the first user equipment can send beam indication information to the second user equipment through the SL resource location information. Specifically, the first user equipment can send beam indication information generated based on the target beam pair to the base station and obtain the SL resource location information scheduled by the base station, and then the first user equipment can send the beam indication information to the second user equipment based on the SL resource location information.

[0143] Understandably, when the second user equipment receives beam indication information from the first user equipment, the second user equipment cannot obtain the specific time-frequency location information of the beam indication. Therefore, it needs to wait for a time T (T = latency bound, configured or pre-configured by higher layer parameters) after sending the beam report. Figure 11 Within the range shown, beam scanning is performed using the receiving beam selected by the second user equipment until beam indication information is received from the first user equipment.

[0144] When the base station selects a target beam pair and sends beam indication information, it can simultaneously send the beam indication information to both the first user equipment and the second user equipment. For example... Figure 17As shown, after receiving the beam report from UE2, the base station can select the target beam pair for communication based on the beam report and generate beam indication information based on the selected target beam pair. Then, the base station can send downlink transmission messages carrying beam pair information to UE1 and UE2, and UE1 and UE2 can complete the initial beam pairing based on the beam pair information carried in the downlink transmission messages.

[0145] In this example, in a scenario where the coverage area is within the network coverage of the base station (i.e., both the first user equipment and the second user equipment are within the network coverage area of ​​the base station), the base station, as the central scheduler for resource allocation, can make beam selection decisions to coordinate different communication beam pairs between UEs within the coverage area and avoid beam collisions.

[0146] The beam management method for a direct link provided in this application embodiment measures the beam scanning channel to obtain a beam report. The beam report is sent to a first user equipment (UE) or base station, whereby the UE or base station determines the target beam pair for communication between the UE and a second UE, and generates beam indication information based on the target beam pair. The beam indication information sent by the UE or base station is received. In this embodiment, the second UE sends the measured beam report to the first UE or base station, allowing the UE or base station to generate beam indication information based on the determined target beam pair, thus achieving beam pair matching between the two UEs. Simultaneously, in coverage scenarios, the base station can make beam selection decisions to coordinate different communication beam pairs between UEs within the coverage area, avoiding beam collisions.

[0147] After beam pairing of the initial beams between the first user equipment and the second user equipment, as described in the embodiments on the first user equipment side and the second user equipment side, beam maintenance can be performed collaboratively by the first user equipment, the second user equipment, and the base station. This beam maintenance process can be described as follows: Figure 18 As shown. The process for the beam maintenance phase is roughly similar to that for the beam pairing phase. The difference is that, for UE2 within the coverage area, when the base station allocates beam scanning channel resources to UE1, it can send the information of those resources to UE2, allowing UE1 and UE2 to start the beam maintenance process simultaneously.
