[0144] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0145] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0146] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0147] See also Figure 1 , Figure 1 is a flowchart of a reporting method provided in an embodiment of the present application, which is applied to a first terminal, such as Figure 1 As shown, the following steps are included:

[0148] Step 101: Receive S-SS / PSBCH block.

[0149] Among them, the first terminal can be a receiving terminal Rx UE. In an embodiment of the present application, a PC5 radio resource control (Radio Resource Control, RRC) connection is established between the transceiver terminals. The transmitting terminal Tx UE can send with different transmission filters on different resources, that is, send different beam directions on different resources. When initial beam pairing or beam management is required between the transceiver terminals performing unicast services, the transmitting terminal sends an S-SS / PSBCH block (or can be abbreviated as S-SSB). Correspondingly, the first terminal as the receiving terminal receives the S-SS / PSBCH block.

[0150] Step 102: determine a first resource, wherein the first resource is used to report first information;

[0151] The first information includes one or more of the following:

[0152] First indication information, first RSRP, first S-SS / PSBCH block index.

[0153] Among them, the first indication information is a 1-bit indication information, which is used to indicate the S-SS / PSBCH block with the largest RSRP among the N received S-SS / PSBCH blocks; the first RSRP is the maximum value among the RSRPs of the N received SS / PSBCH blocks; the first S-SS / PSBCH block index is the S-SS / PSBCH block index corresponding to the first RSRP. The N SS / PSBCH blocks belong to one S-SS / PSBCH period, wherein N is configured by a high-level parameter and is an integer greater than or equal to 1.

[0154] In the embodiment of the present application, the first resource may be determined by one or more of the following methods:

[0155] (1) Determine the first resource according to the first S-SS / PSBCH block.

[0156] In this method, the first resource can be determined based on one or more of the time slot index, subchannel index, first terminal identifier and second terminal identifier of the first S-SS / PSBCH block; or, the first resource can be determined based on one or more of the time slot index, subchannel index, first terminal identifier and second terminal identifier of the second resource, wherein the mapping relationship between the second resource and the first S-SS / PSBCH block is defined by the protocol, or is configured or pre-configured for the resource pool.

[0157] Among them, the second terminal is the sending terminal. This method can be called an implicit reporting method. In this method, the association relationship between each S-SSB resource and the reporting resource (i.e., the first resource) is defined, and the second terminal is implicitly notified to send beam information. The sending terminal uses the beam direction of the S-SSB to receive within the reporting resource or reporting window associated with it.

[0158] If the reporting resource is in the resource pool, the SL physical sidelink feedback channel (PSFCH) time slot is used and frequency division multiplexed (FDM) with the PSFCH resource. In this case, it is necessary to distinguish whether the S-SSB is located outside the resource pool or inside the resource pool:

[0159] 1) If the protocol supports configuring a new S-SSB resource for beam pairing, and the resource is located in a resource pool, the first resource is determined according to one or more of the time slot index (such as time domain and frequency domain position) of the first S-SS / PSBCH block, the subchannel index, the first terminal identifier, and the second terminal identifier. The first terminal identifier or the second terminal identifier may be the source ID and destination ID of layer 1. The first terminal sends 1 bit of indication information on the first resource.

[0160] See also Figure 2 , showing a schematic process of determining the first resource in the above manner. For example, the candidate reporting resource associated with the first S-SS / PSBCH block can be determined in the order of time first and frequency second according to the time slot index (such as time domain and frequency domain position) and the subchannel index of the first S-SS / PSBCH block, and the candidate reporting resource is in the same PSFCH time slot, but is different from the frequency domain resource FDM of the PSFCH. Afterwards, the first resource is determined from the candidate reporting resources according to the first terminal identifier and the second terminal identifier.

[0161] For example, in Figure 2 In the figure, the PSFCH period is 4, that is, a PSFCH time slot appears every 4 time slots, among which the candidate reporting resources for the first information and the PSFCH feedback resources (the resources indicated by 21 in the figure) are FDM. Figure 2 The example in the example determines the candidate reporting resources in the order of time first and frequency second, that is, according to the time slot index of a certain SSB (depending on PSFCHperiod, Figure 2 In PSFCH period = 4, the timeslot index is 0 to 3) and the subchannel index (depending on the configuration of the resource pool, Figure 2 The resource pool includes 2 subchannels, and the subchannel index is 0 to 1) to determine the corresponding candidate reporting resource. At this time, the position of SSB#0 is time slot index 2, and the subchannel index is 1, and the corresponding candidate reporting resource is the 7th reporting resource (the 7th PRB from top to bottom); then, according to the identification of the first terminal and / or the second terminal, the cyclic offset (i.e., the first resource) used is determined.

[0162] 2) If the protocol supports configuring a new S-SSB resource for beam pairing, and the resource is located outside the resource pool, or reusing an existing S-SSB resource for beam pairing (the existing S-SSB resource is located outside the resource pool), the first resource is determined using one or more of the time slot index (such as time domain and frequency domain position) of the resource associated with the S-SSB resource (i.e., the second resource), the subchannel index, the first terminal identifier, and the second terminal identifier. The mapping relationship between the second resource and the first S-SS / PSBCH block is defined by the protocol, or is configured or pre-configured for the resource pool.

[0163] For example, the candidate reporting resource associated with the second resource can be determined according to the time slot index (such as the time domain and frequency domain position) and the subchannel index. Then, the first resource is determined from the candidate reporting resources according to the first terminal identifier and the second terminal identifier.

[0164] For example, see Figure 3 , shows a schematic process of determining the first resource in the above manner. Figure 3 In the figure, PSFCHperiod is 4, that is, there is a PSFCH time slot every 4 time slots, among which the candidate reporting resources for the first information and the PSFCH feedback resources (the resources indicated by 31 in the figure) are FDM. Figure 3 The example in the example determines the candidate reporting resources in the order of time first and frequency second, that is, according to the time slot index of the associated resource of a certain SSB in the resource pool (depending on the PSFCH period, Figure 3 In PSFCHperiod=4, the time slot index takes values ​​from 0 to 3) and the subchannel index (depending on the configuration of the resource pool, Figure 3 The resource pool includes 2 sub-channels, and the sub-channel index is 0-1) to determine the corresponding candidate reporting resource. At this time, SSB#0 is located outside the resource pool, and the resource in the resource pool associated with it is located at the time slot index 1, and the sub-channel index is 0, then the corresponding candidate reporting resource is the first reporting resource (the first PRB from top to bottom); then, according to the identification of the first terminal and / or the second terminal, the cyclic offset (i.e., the first resource) used is determined.

[0165] If the reported resource is outside the resource pool, the first resource is located in M ​​symbols in the S-SS / PSBCH block time slot, where M is an integer greater than or equal to 2. In this manner, the first resource is determined according to one or more of the time slot index of the first S-SS / PSBCH block, the first terminal identifier, and the second terminal identifier. This manner may be referred to as an implicit reporting manner.

[0166] Specifically, in an embodiment of the present application, the S-SSB time slot is utilized, a new S-SSB time slot structure is designed, and an S-SSB time slot containing reporting resources is introduced.

[0167] See also Figure 4 , the S-SSB measurement reporting time slot is introduced, and the reporting time slot contains M reporting symbols, where M is defined by the protocol or (pre) configured, and the typical value of M is 2, where the second symbol is the reporting symbol and the first symbol is a copy of the second symbol for automatic gain control (AGC). The number of symbols occupied by S-SSB is reduced accordingly (reducing the symbols of the original PSBCH).

[0168] See also Figure 5 The period of occurrence of the reporting time slot, the processing time interval that the reporting needs to meet, and the frequency domain resources for S-SSB reporting are (pre) configured or protocol defined. The terminal determines the candidate reporting resources in sequence according to the time slot index of the S-SSB resource, and further determines the reporting resource according to the identity of the transmitting and receiving UE.

[0169] (2) Determine a first time interval according to a first S-SS / PSBCH block, and select a first resource in the first time interval.

[0170] In this method, a reporting resource window (i.e., a first time interval) associated with each S-SSB resource is defined, and the first terminal selects a reporting resource in the reporting resource window, wherein the reporting of the first information is carried in a high-level signaling (e.g., a media access control (MAC) control element (CE), PC5-RRC). This method can be called an implicit reporting method.

[0171] For example, the first time interval may be determined to be [TA, TB], where TA is the start time and TB is the end time. The sending terminal configures the start time TA and the end time TB of the reporting window associated with each S-SSB resource (e.g., configured by a direct frame number (DFN)). The parameters TA and TB are provided by high-level parameters, or are configured or pre-configured by a resource pool.

[0172] Alternatively, the first time interval is determined to be [n+T1, n+T2], where n is the time slot of the first S-SS / PSBCH block, 0≤T1≤T1', 0≤T2≤T2', and T1 and T2 are selected by the implementation of the first terminal. In this case, the reporting window associated with the S-SSB resource located in time slot n is [n+T1, n+T2]. T1 and T2, which may be referred to as first parameters and second parameters, may be configured by the transmitting terminal, preconfigured, or defined by the protocol, etc. Alternatively, T1 is defined based on the first parameter, and T2 is defined based on the second parameter, where the selection of the first parameter and the second parameter depends on the specific implementation of the first terminal. Among them, parameters T1' and T2' are provided by high-level parameters, or configured or preconfigured by the resource pool.

[0173] Alternatively, the first time interval is determined to be (n, n+T3], where n is the time slot of the first S-SS / PSBCH block, and T3≥0. In this case, the first terminal needs to feedback the reporting content before n+T3. T3 can be called a third parameter, which can be configured by the sending terminal, preconfigured, or defined by the protocol. Alternatively, T3 is defined based on the third parameter, where the selection of the third parameter depends on the specific implementation of the first terminal. T3 can also be provided by a high-level parameter, or configured or preconfigured by a resource pool.

[0174] See also Figure 6 For example, SSB#0 is reported in reporting window Report window#0, SSB#1 is reported in reporting window Report window#1, and so on.

[0175] (3) Determine the first resource according to the second S-SS / PSBCH block.

[0176] The second S-SS / PSBCH block is one of N S-SS / PSBCH blocks, where N is the number of S-SS / PSBCH blocks in one S-SS / PSBCH block period, and is an integer greater than or equal to 1.

[0177] In this manner, the first resource is located in M ​​symbols in the S-SS / PSBCH block time slot, where M is an integer greater than or equal to 2. For example, the first resource may be determined according to one or more of the time slot index of the second S-SS / PSBCH block, the first terminal identifier, and the second terminal identifier. In this manner, an S-SSB time slot containing reporting resources may be introduced through a new S-SSB time slot structure. For a specific time slot structure, refer to Figure 4 For example, the candidate reporting resource associated with the second S-SS / PSBCH block can be determined according to the time slot index (such as the time domain and frequency domain position) of the second S-SS / PSBCH block. Then, the first resource is determined from the candidate reporting resources according to the first terminal identifier and the second terminal identifier.

[0178] Alternatively, in this manner, the first resource is determined according to one or more of the time slot index, subchannel index, first terminal identifier, and second terminal identifier of the second S-SS / PSBCH block. For example, the candidate reporting resource associated with the second S-SS / PSBCH block can be determined according to the time slot index (such as time domain and frequency domain position) and subchannel index of the second S-SS / PSBCH block. Afterwards, the first resource is determined from the candidate reporting resources according to the first terminal identifier and the second terminal identifier.

[0179] Alternatively, the first resource is determined according to one or more of the time slot index, subchannel index, first terminal identifier and second terminal identifier of the third resource, wherein the mapping relationship between the third resource and the second S-SS / PSBCH block is defined by the protocol, or is configured or pre-configured for the resource pool. For example, the candidate reporting resource associated with the third resource can be determined according to the time slot index (such as the time domain and frequency domain position) and subchannel index of the third resource. Afterwards, the first resource is determined from the candidate reporting resources according to the first terminal identifier and the second terminal identifier.

[0180] In this way, an association relationship between a group of S-SSB resources and a reporting resource (i.e., the first resource) is defined. Since the second S-SS / PSBCH block is one of the N S-SS / PSBCH blocks, it is equivalent to displaying the information of the S-SS / PSBCH block, so it can be called a displayed report. In this case, the transmitting terminal uses an omnidirectional beam to receive within the reporting resource or reporting window. Among them, the time slot index of the second S-SS / PSBCH block can be reported using the physical uplink control channel (Physical Uplink Control Channel, PUCCH) format 2 (format 2).

[0181] (4) determining a second time interval according to a second S-SS / PSBCH block, and selecting the first resource in the second time interval, wherein the second S-SS / PSBCH block is one of N S-SS / PSBCH blocks, and N is the number of S-SS / PSBCH blocks in one S-SS / PSBCH block period, which is an integer greater than or equal to 1.

[0182] In this way, a reporting resource window associated with a group of S-SSB resources is defined, and the window is determined based on the time domain position of a certain S-SSB resource in a group of S-SSBs, and the S-SSB is configured by the sending terminal, high-level parameter (pre) configuration or protocol definition. The receiving terminal selects the reporting resource in the window, and the report is carried in the high-level signaling (such as MAC-CE, PC5-RRC).

[0183] For example, the second time interval may be determined to be [TA1, TB1], where TA1 is the start time and TB1 is the end time. The sending terminal configures the start time TA1 and the end time TB1 of the reporting window associated with each S-SSB resource (e.g., configured by DFN). The parameters TA1 and TB1 are provided by high-level parameters, or are configured or pre-configured by a resource pool.

[0184] Alternatively, the second time interval is determined to be [m+T5, m+T6], where m is the time slot of the second S-SS / PSBCH block, 0≤T5≤T5', 0≤T6≤T6', and T5 and T6 are selected by the implementation of the first terminal. In this case, the reporting window associated with the S-SSB resource located in time slot n is [m+T5, m+T6]. T5 and T6, which may be referred to as the fifth parameter and the sixth parameter, may be configured by the transmitting terminal, preconfigured, or defined by the protocol, etc. Alternatively, T5 is defined based on the fifth parameter, and T6 is defined based on the sixth parameter, wherein the selection of the fifth parameter and the sixth parameter depends on the specific implementation of the first terminal. Among them, parameters T5' and T6' are provided by high-level parameters, or configured or preconfigured by the resource pool.

[0185] Alternatively, the second time interval is determined to be (m, m+T7], where m is the time slot of the second S-SS / PSBCH block, and T7≥0; in this case, the first terminal needs to feedback the reporting content before m+T7. T7 can be called the seventh parameter, which can be configured by the sending terminal, preconfigured, or defined by the protocol, etc. Alternatively, T7 is defined based on the seventh parameter. The selection of the seventh parameter depends on the specific implementation of the first terminal. T7 can also be provided by a high-level parameter, or configured or preconfigured by a resource pool.

[0186] Among them, parameters TA1, TB1, T5', T6', and T7 are provided by high-level parameters, or are configured or pre-configured by a resource pool.

[0187] In an embodiment of the present application, the first terminal determines the S-SS / PSBCH block and determines the first resource for reporting the first information, thereby determining the reporting resources and reporting content in the initial beam pairing, which can improve resource utilization.

[0188] See also Figure 7 , Figure 7 is a flow chart of a sending method provided in an embodiment of the present application, which is applied to a second terminal, such as Figure 7 As shown, the following steps are included:

[0189] Step 701: Send S-SS / PSBCH block.

[0190] Among them, the second terminal can be a transmitting terminal. In an embodiment of the present application, a PC5RRC connection is established between the transmitting and receiving terminals. The transmitting terminal Tx UE can transmit with different transmission filters on different resources, that is, send different beam directions on different resources. When initial beam pairing or beam management is required between the transmitting and receiving terminals performing unicast services, the transmitting terminal sends an S-SS / PSBCH block.

[0191] Step 702: Receive first information, wherein the first information includes one or more of the following:

[0192] First indication information, first RSRP, first S-SS / PSBCH block index.

[0193] Optionally, the second terminal may also determine the first S-SS / PSBCH block. For example, the second terminal may determine the first S-SS / PSBCH block in one or more of the following ways:

[0194] Determine the first S-SS / PSBCH block according to the first indication information;

[0195] Determine the first S-SS / PSBCH block according to the first RSRP;

[0196] The first S-SS / PSBCH block is determined according to the first S-SS / PSBCH block index.

[0197] Among them, the first indication information is a 1-bit indication information, which is used to indicate the S-SS / PSBCH block with the largest RSRP among the N received S-SS / PSBCH blocks; the first RSRP is the maximum value among the received; the first S-SS / PSBCH block index is the S-SS / PSBCH block index corresponding to the first RSRP. These N SS / PSBCH blocks belong to one S-SS / PSBCH period, where N is configured by high-level parameters and is an integer greater than or equal to 1.

[0198] After determining the first S-SS / PSBCH block, the second terminal may also perform other operations, such as synchronization.

[0199] In an embodiment of the present application, the first terminal determines the S-SS / PSBCH block and determines the first resource for reporting the first information, thereby determining the reporting resources and reporting content in the initial beam pairing, which can improve resource utilization and enhance beam coverage, thereby ensuring communication quality.
