FIG. 2 shows a schematic flowchart of a data receiving method in an embodiment of the present application, and the method 200 may be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in Fig. 2, the method may include the following steps.

S210, the receiving terminal in the secondary link determines a receiving beam according to the first rule.

In the embodiment of the present application, the receiving terminal (RX (Receive) UE) may be a relay terminal in the secondary link, or may be a remote terminal in the secondary link, which is not specifically limited in the embodiment of the present application.

In the embodiment of this application, in order to combat the high transmission path loss or occlusion problem on the FR2 band, the sidelink UE can use beams for transmission when transmitting on the FR2 band. For a pair of transmitting terminal (TX (Transmit) UE) and receiving terminal (RX UE), TX UE uses TX beam (beam) for transmission, and RX UE uses RX beam for reception, which can improve the signal strength and/or coverage of transmission scope.

Among them, Sidelink UE can adopt a multi-panel transceiver structure, and each panel can correspond to a beam in a specific direction, and send/receive in the direction of its own beam. Therefore, in the embodiment of the present application, the RX UE determines the receiving beam according to the first rule.

It should be noted that the beam in the embodiment of the present application may be a spatial domain filter (spatial domain filter), a precoder (precoder), a reference signal resource identifier (RS resource index), a transmission configuration indicator (Transmission Configuration Indicator, TCI), antenna panel (antenna panel), etc.

S212. The receiving terminal uses the receiving beam to receive the transmission on the secondary link.

In this embodiment of the application, the receiving terminal can determine the receiving beam corresponding to each resource according to the first rule, and use the determined receiving beam to receive the secondary link transmission on the corresponding resource, instead of receiving a TX from a certain directional beam UE transmission, so as to avoid the problem of not being able to receive the transmission of TX UEs from other directions, and not being able to accurately detect the occupancy of the channel.

In a possible implementation manner of the embodiment of the present application, the first rule may include using the first beam to perform reception on the first target resource.

In a first possible implementation manner, the first target resource may include at least one of the following: preset time domain resources and preset frequency domain resources. For example, all resources in the resource pool, that is, the receiving terminal always uses the first beam for reception.

Wherein, the first beam may be a preset beam, for example, an omnidirectional beam, or a beam independently determined by the receiving terminal. Wherein, the beam independently determined by the receiving terminal refers to the receiving beam determined and used by the receiving terminal according to its own situation, for example, the receiving terminal determines the receiving beam according to the receiving direction, and the receiving terminal determines the beam with the largest radiation angle as the receiving beam according to its antenna radiation pattern, etc.

Wherein, the preset beam may include one of the following: a beam stipulated in the agreement, a beam configured by the control node, and a preconfigured beam, that is, the preset beam may be agreed by the protocol, configured by the control node, or preconfigured.

Alternatively, the agreement may stipulate that the first beam used for receiving on the first target resource is the same beam or a beam with a quasi-co-location relationship. For example, the agreement stipulates that the receiving terminal adopts beams with the same or quasi-co-location relationship to perform reception in preset time domain resources and/or frequency domain resources (eg, resource pool).

In a second possible implementation manner, the first target resource may include resources occupied by the first target information, where the first target information includes at least one of the following: a preset channel, a preset symbol, a preset set information.

Optionally, the preset channel may include: a physical sidelink control channel (Physical SideLink Control Channel, PSCCH).

Optionally, the preset symbols may include: symbols occupied by sidelink control information (Sidelink Control Information, SCI). For example, the first symbol of the PSCCH is mapped to the last symbol of the ^2nd SCI; the symbol indicated by the control node, etc.

Optionally, the preset information may include: physical layer SCI.

In the secondary link, a physical sidelink shared channel (Physical SideLink Shared Channel, PSSCH) is used to transmit data. The control information associated with the PSSCH is carried in the SCI of the PSCCH and the PSSCH respectively. Among them, the SCI is divided into two levels, the ^1st stage SCI is in the PSCCH, and the ^2nd stage SCI is in the PSSCH. The preset information may include ^1st stage SCI and/or ^2nd stage SCI.

In this possible implementation manner, the first beam may be a preset beam, for example, an omnidirectional beam, or a beam independently determined by the receiving terminal. Wherein, the beam independently determined by the receiving terminal refers to the receiving beam determined and used by the receiving terminal according to its own situation.

Wherein, the preset beam may include one of the following: a beam stipulated in the agreement, a beam configured by the control node, and a pre-configured beam, that is to say, the preset beam may be agreed by the protocol, configured by the control node, or pre-configured, For example, it is pre-configured in the receiving terminal before the receiving terminal leaves the factory.

In addition, the first beam used by the receiving terminal to perform reception on the first target resource is the same beam or a beam with a quasi-co-location relationship. For example, the RX UE uses the same beam or a beam with a quasi-co-location relationship to receive on a preset channel or a preset symbol.

In the above second possible implementation manner, optionally, the first rule may further include: determining the second beam used on the second target resource according to the first beam indication information, where the second target resource Resources occupied by the second target information are included, wherein the second target information includes at least one of the following:

At least some channels other than the preset channel; for example, PSSCH.

At least some symbols other than the preset symbols. For example, the symbol after the ^2nd SCI in PSSCH; the symbol configured by the control node, etc.

Wherein, the first beam indication information is included in the SCI associated with the second target resource.

Optionally, the first beam indication information may be indicated by a control node, for example, the first beam indication information is indicated by a base station or a UE having control power. Or the first beam indication information may also be indicated by the sending terminal (TX UE).

For example, the TX UE indicates that the first beam indication information may include one of the following:

(1) TX UE directly indicates TCI configuration, Quasi co-location (Quasi co-location, QCL) relationship, etc.

(2) The TX UE indirectly indicates the beam by indicating time domain and/or frequency domain information, where the time domain and/or frequency domain information is associated with beam information, and the association relationship may be agreed/configured/preconfigured in the protocol.

(3) The TX UE sends a hybrid automatic repeat request (HARQ) process, a transport block (Transport Block, TB), or a physical sidelink feedback channel (Physical SideLink Feedback Channel, PSFCH) indirectly by instructing it to send before Indicates a beam, where the previous transmission of a certain TB and the current transmission of a TB use the same beam or a beam with a quasi-co-location relationship.

(4) The TX UE indirectly indicates the beam by indicating the HARQ process, TB, or PSFCH of the previously received RX UE, where the previous reception of a TB and the current TB transmission use the same beam or a beam with a quasi-co-location relationship.

For example, when the TX UE performs PSCCH and/or PSSCH multicast transmission, the TX UE retransmits the RX UE that sent a negative acknowledgment (Negative Acknowledgment, NACK). At this time, the PSCCH can be adjusted according to the PSFCH transceiver beam of the RX UE that sent the NACK and/or a transmit beam for PSSCH retransmission. Wherein, the sending beam for retransmission may be implicitly indicated.

In a possible implementation manner, the first rule may include: before the target transmission, if the second beam indication information for the target transmission is not obtained, use the first beam to receive the target transmission; Before, if the second beam indication information for the target transmission is acquired, determine the receiving beam of the target transmission according to the second beam indication information.

That is to say, in this possible implementation, if the RX UE acquires the beam indication information for a certain transmission (such as PSCCH and/or PSSCH retransmission) in advance, the RX UE determines the receiving beam according to the beam indication information.

Optionally, the second beam indication information may be included in the SCI associated with the target transmission, for example, the SCI included in the last PSCCH and/or PSSCH transmission.

Optionally, the second beam indication information may be indicated by a control node (for example, a base station or a UE with a control function) and/or a sending terminal.

The manner in which the TX UE indicates the second beam indication information is similar to the manner in which the first beam indication information is indicated, and for details, refer to the above description about the TX UE indicating the first beam indication information.

Optionally, if the RX UE does not obtain in advance the beam indication information corresponding to the reception on a certain time domain and/or frequency domain resource (such as the initial transmission of TB), the RX UE uses a specific beam (ie, the first beam) to receive. Optionally, the specific beam may be a preset beam (such as an omnidirectional beam), or a beam independently determined by the RX UE. Wherein, the preset beam may be stipulated in the protocol, configured by the control node, or pre-configured.

In a possible implementation manner, the first rule may include: receiving on the third target resource using the first beam, and/or using the third beam on the fourth target resource to receive. That is to say, in this possible implementation manner, the RX UE adopts specific beam reception (such as omnidirectional beam reception ), and/or the indicated beam (for example, directional beam reception) may be used on other preset resources (for example, the fourth target resource).

Optionally, the third target resource may include at least one of the following: dedicated resources for groupcast transmission and dedicated resources for broadcast transmission.

Optionally, the third target resource may be configured by the control node, or pre-configured.

In the foregoing possible implementation manner, the third target resource may be set corresponding to one transmission type, or the third target resource may be set corresponding to multiple transmission types. For example, the third target resource is independently set for one transmission type, or the third target resource is independently set for multiple different transmission types.

Optionally, the fourth target resource includes dedicated resources for unicast transmission.

Optionally, the fourth target resource may be configured by the control node, or pre-configured.

Optionally, the fourth target resource is a resource used for data transmission between terminal pairs negotiated between the receiving terminal and the sending terminal. For example, the RX UE and the TX UE can negotiate the time domain and/or frequency domain resources used for data transmission between the UE-pair, so that the transmission of different TX UEs corresponding to the RX UE is time division multiplexing (Time division multiplexing, TDM) transmission , the RX UE only needs to use one beam to receive at a certain moment.

Optionally, the first beam may be a preset beam, for example, an omnidirectional beam, or may also be a beam independently determined by the RX UE. Wherein, the preset beam may be stipulated in the protocol, configured by the control node, or pre-configured.

Optionally, the third beam may be the beam indicated by the third beam indication information. Wherein, the third beam indication information may be indicated by a control node (such as a base station or a UE having a control function), or may also be indicated by a TX UE. The manner in which the TX UE indicates the third beam indication information is similar to the manner in which the first beam indication information is indicated, and for details, refer to the above description about the TX UE indicating the first beam indication information.

Optionally, the third beam may also be the first beam.

In a possible implementation manner, the first rule may further include: when the receiving terminal does not support using multiple beams for reception on the fifth target resource, and the receiving terminal is set to use multiple beams on the fifth target resource In the case of receiving on the fifth target resource, the receiving terminal determines the receiving beam according to one of the following (1) to (4). Wherein, the receiving terminal is configured to use multiple beams to receive on the fifth target resource may be an instruction from the control node, an instruction from the sending terminal, or an agreement that the receiving terminal uses multiple beams to receive on the fifth target resource.

(1) Determine to preferentially adopt the beam corresponding to the first transmission and/or abandon the beam corresponding to the second transmission according to the attribute information of the transmission, wherein the attribute information includes at least one of the following: priority information, quality of service (quality of service) , QoS) information. Wherein, the QoS information may include reliability (reliability), delay (latency), packet delay budget (packet delay budget, PDB) and the like.

For example, directional beams corresponding to low-priority transmissions or low-QoS transmissions (including transmissions with low reliability, transmissions with larger PDBs or remaining PDBs, etc.) are (preferentially) abandoned.

Optionally, in this possible implementation manner, when the beam corresponding to the second transmission is abandoned, the sending terminal corresponding to the second transmission may be triggered to perform resource reselection.

Optionally, in this possible implementation manner, the receiving terminal may notify the sending terminal of the time domain and/or frequency domain resources that the receiving terminal tends to use by the sending terminal, where the time domain and/or frequency domain resources correspond to the first transmission The corresponding beam, and/or, may also notify the sending terminal of time domain and/or frequency domain resources that the receiving terminal does not tend to use by the sending terminal, where the time domain and/or frequency domain resource corresponds to the beam corresponding to the second transmission.

(2) Using the first beam to receive on the fifth target resource.

Optionally, the first beam may be a preset beam (such as an omnidirectional beam), or a beam independently determined by the RX UE. Wherein, the preset beam may be stipulated in the protocol/configured by the control node/pre-configured.

(3) Use the fifth beam to receive on the fifth target resource, where the fifth beam is the beam indicated by the beam indication information; for example, the RX UE preferentially uses the indicated beam to receive on the fifth target resource.

(4) Using the sixth beam to receive on the fifth target resource, where the sixth beam is a beam corresponding to a larger number of sending terminals and/or a corresponding larger number of transmission blocks. For example, the RX UE (priority) uses the receiving beam corresponding to more TX UEs and/or more TB transmissions to receive in the time domain and/or frequency domain resources (ie, the fifth target resource).

Alternatively, the negotiation between the RX UE and the TX UE or proximity UE (such as negotiating the time domain and/or frequency domain resources used for transmission between pair-UEs) can be used to prevent the RX UE from using multiple (directional) beams in a certain time domain and/or receive on frequency domain resources. That is, the RX UE enables multiple (directional) receive beams in a TDM manner.

In a possible implementation manner, the first rule may include: determining the receiving beam according to a preset reference direction.

Optionally, the preset reference direction includes one of the following: a protocol-agreed reference direction, a control node configured reference direction, and a pre-configured reference direction. For example, use an absolute direction as the reference direction.

Optionally, in the foregoing possible implementation manner, after the receiving terminal determines the receiving beam according to the first rule, the method further includes: carrying the first information in the first signaling sent by the receiving terminal, Wherein, the first signaling is used to indicate and/or reserve receiving resources, and the first information includes at least one of the following: beam information and location information of the receiving terminal. For example, when the UE performs reception resource indication or reservation, beam information and/or UE location information are carried in corresponding signaling (such as SCI).

Optionally, in the above possible implementation manner, before the receiving terminal determines the receiving beam according to the first rule, the method further includes: the receiving terminal selects the receiving resource according to the monitored second information , wherein the second information includes at least one of the following: location information of the adjacent terminal, beam indication information sent by the adjacent terminal, and resource occupation information of the adjacent terminal. For example, when the UE performs sensing and reception resource selection, it detects/monitors the beam indication information sent by the nearby UE, and/or the location information of the nearby UE (or the relative location information between the nearby UE and the UE), and/or the location information of the nearby UE Resource occupancy and other information for resource selection.

Optionally, the adjacent terminal includes an adjacent sending terminal. For example, the adjacent UE includes at least an adjacent TX UE, and the beam indication information includes at least a transmission beam indicated by the adjacent TX UE.

In the foregoing possible implementation manner, the adjacent terminals may be determined according to one of the following: location information between terminals, energy measurement results between terminals, and signal quality measurement results between terminals.

Through the technical solution provided by the embodiment of this application, the receiving beam of the RX UE can be set, so that the RX UE can use receiving beams in multiple directions to receive the transmission of the secondary link, thereby preventing the RX UE from only adopting a certain orientation The RX beam receives the transmission from a TX UE, but may not receive the transmission from the TX UE in other directions, and cannot accurately detect the occupancy of the channel.

In this embodiment of the application, the sending terminal (TX UE) may be a relay terminal in the secondary link, or a remote terminal in the secondary link, which is not limited in this embodiment of the application.

In the embodiment of this application, in order to combat the high transmission path loss or occlusion problem on the FR2 band, the sidelink UE can use beams for transmission when transmitting on the FR2 band. For a pair of transmitting terminal (TX UE) and receiving terminal (RX UE), TX UE uses TX beam (beam) for transmission, and RX UE uses RX beam for reception, which can improve the signal strength and/or coverage of transmission.

Among them, Sidelink UE can adopt a multi-panel transceiver structure, and each panel can correspond to a beam in a specific direction, and send/receive in the direction of its own beam. Therefore, in the embodiment of the present application, before performing the target transmission, the TX UE determines the transmission beam of the target transmission.

S312. The sending terminal uses the sending beam to perform the target transmission on the secondary link.

Through the technical solution provided by the embodiment of the present application, the TX UE can perform target transmission with a beam, thereby reducing the path loss in the secondary link transmission and improving the transmission signal strength.

In a possible implementation manner, the sending terminal determining the sending beam may include: the sending terminal determining to perform a transport block (TB) transmission in the form of a resource set; the sending terminal determining the target transmission beam based on at least one resource set The transmit beam to use.

For example, in broadcast or multicast transmission, the sending terminal can perform a TB transmission in the form of a resource set, including TB initial transmission and TB retransmission. Wherein, the resource set may include: a time-domain resource and/or a frequency-domain resource set of the PSCCH, and/or a time-domain resource and/or a frequency-domain resource set of the PSSCH.

Optionally, the sizes of the resources in the same resource set are the same, of course, it is not limited thereto, and in specific applications, the sizes of the resources in the same resource set may also be different.

Optionally, the number of resources in one resource set is a predetermined value, and the predetermined value is determined by one of the following: protocol agreement, control node configuration, pre-configuration, and autonomous determination by the sending terminal.

Optionally, optionally, the preset sending beam pattern may be agreed upon in the protocol, configured by the control node, or preconfigured.

In a possible implementation manner, there is a quasi-co-location relationship between the first sending beam and the second sending beam, where the first sending beam corresponds to the first resource in the first resource set, and the second sending beam corresponds to the first resource in the first resource set. The second resource in the two resource sets, the at least one resource set includes the first resource set and the second resource set. That is to say, the transmission beams corresponding to the resources among the resource sets have a quasi-co-location relationship, wherein the transmission beams with the quasi-co-location relationship correspond to the same beam.
