Fig. 2 shows a schematic flow chart of a data receiving method in the embodiment of the present application, and the method 200 may be executed by a terminal. In other words, the method may be performed 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 a first rule.

In this embodiment, the receiving terminal (RX UE) may be a relay terminal in the sidelink, or may be a remote terminal in the sidelink, and this embodiment is not limited in this application.

In the embodiment of the present application, in order to counter the problem of high transmission path loss or shielding on the FR2 band, the sidelink UE may use a beam for transmission when transmitting on the FR2 band. For a pair of a transmitting terminal (TX UE) and a receiving terminal (RX UE), the TX UE transmits using a TX beam (beam), and the RX UE receives using an RX beam, which may improve the signal strength and/or coverage of the transmission.

The Sidelink UE may employ a transceiver structure with multiple panels, and each panel may transmit/receive data in a direction of the beam corresponding to the particular direction. Therefore, in the embodiment of the present application, the RX UE determines the reception 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 (TCI), an antenna panel (antenna panel), or the like.

S212, the receiving terminal receives the transmission on the secondary link by using the receiving beam.

In this embodiment of the present application, the receiving terminal may determine, according to the first rule, a receiving beam corresponding to each resource, and receive, by using the determined receiving beam, sidelink transmission on the corresponding resource, instead of receiving transmission from a certain TX UE by a certain directional beam, so as to avoid the problems that transmission from TX UEs in other directions cannot be received, and the occupation situation of a channel cannot be accurately detected.

In one possible implementation of the embodiment of the present application, the first rule may include receiving on the first target resource using the first beam.

In a first possible implementation, the first target resource may include at least one of: presetting time domain resources and presetting frequency domain resources. For example, all resources in the resource pool, that is, the receiving terminal always receives with the first beam.

The first beam may be a preset beam, for example, an omni-directional beam, or a beam autonomously determined by the receiving terminal. The beam autonomously determined by the receiving terminal is a receiving beam determined by the receiving terminal according to its own condition, 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.

Wherein the preset beam may include one of: a protocol-agreed beam, a control node-configured beam, a pre-configured beam, that is, a pre-set beam may be protocol-agreed, control node-configured, or pre-configured.

Alternatively, the protocol may agree that the first beam used for receiving on the first target resource is the same beam or a beam having a quasi-co-location relationship. For example, the protocol provides that the receiving terminal receives in a preset time domain resource and/or frequency domain resource (e.g., a resource pool) by using the same or a beam having a quasi-co-location relationship.

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

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

Optionally, the preset symbol may include: sidelink control information (Si)delink Control Information, SCI). For example, the first symbol to 2 of the PSCCH ^nd The last symbol of the SCI map; symbol indicated by the control node, etc.

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

In the secondary link, a Physical SideLink Shared Channel (pscch) is used to transmit data. Control information associated with PSSCH is carried in SCI of PSCCH and PSSCH respectively. Wherein SCI is divided into two stages, 1 ^st stage SCI in PSCCH, 2 ^nd stage SCI is in PSSCH. The preset information may include 1 ^st stage SCI and/or 2 ^nd stage SCI。

In this possible implementation, the first beam may be a preset beam, e.g., an omni-directional beam, or a beam autonomously determined by the receiving terminal. The beam determined by the receiving terminal autonomously refers to a receiving beam determined by the receiving terminal according to the self condition.

Wherein the preset beam may include one of: a protocol-agreed beam, a control node-configured beam, a pre-configured beam, that is, a pre-set beam may be protocol-agreed, control node-configured, or pre-configured, for example, pre-configured in the receiving terminal before the receiving terminal leaves the factory.

In addition, the first beams adopted by the receiving terminal for receiving on the first target resource are the same beams or beams with quasi-co-location relation. For example, the RX UE receives on a preset channel or a preset symbol using the same beam or a beam with quasi-co-location relationship.

In the second possible implementation manner, optionally, the first rule may further include: determining a second beam used on a second target resource according to the first beam indication information, wherein the second target resource comprises a resource occupied by second target information, and the second target information comprises at least one of the following:

at least a part of channels except the preset channel; such as the psch.

Except for the presettingAt least some of the symbols other than the symbol. E.g. PSSCH 2 ^nd Symbol after SCI; control node configured symbol, etc.

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

Alternatively, the first beam indication information may be indicated by the control node, e.g. by a base station, or a UE with controlled power. Or the first beam indication information may also be indicated by the transmitting terminal (TX UE).

For example, the TX UE indicating the first beam indication information may include one of:

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

(2) The TX UE indicates the beam indirectly by indicating a form of time domain and/or frequency domain information, wherein the time domain and/or frequency domain information is associated with the beam information, which association may be protocol agreed/configured/preconfigured.

(3) The TX UE indicates a beam indirectly by indicating a previous HARQ process, a Transport Block (TB), or a Physical SideLink Feedback Channel (PSFCH), where the previous transmission of a TB and the current transmission of the TB use the same beam or a beam with a quasi-co-location relationship.

(4) The TX UE indirectly indicates a beam through indicating the HARQ process, the TB or the PSFCH of the RX UE received before, wherein the receiving of a certain TB and the transmitting of the TB adopt the same beam or the beam with the quasi-co-location relation.

For example, when the TX UE performs PSCCH and/or PSCCH multicast transmission, the TX UE retransmits the RX UE that sent the NACK, and at this time, the transmission beam for the PSCCH and/or PSCCH retransmission may be adjusted according to the PSFCH transceiving beam of the RX UE that sent the NACK. Wherein the retransmitted transmit beam may be implicitly indicated.

In one possible implementation, the first rule may include: receiving target transmission by adopting a first wave beam under the condition that second wave beam indication information aiming at the target transmission is not acquired before the target transmission; and determining a receiving beam of the target transmission according to the second beam indication information under the condition of acquiring the second beam indication information aiming at the target transmission before the target transmission.

That is, in this possible implementation, if the RX UE acquires the beam indication information for a certain transmission (e.g., PSCCH and/or PSCCH retransmission) in advance, the RX UE determines a reception beam according to the beam indication information.

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

Alternatively, the second beam indication information may be indicated by a control node (e.g., a base station or a UE having a control function), and/or a transmitting terminal.

The manner in which the TX UE indicates the second beam indication information is similar to the manner in which the TX UE indicates the first beam indication information, which may be specifically referred to the above description about the TX UE indicating the first beam indication information. .

Optionally, if the RX UE does not acquire the beam indication information corresponding to reception on a certain time and/or frequency domain resource (e.g., initial transmission of a TB) in advance, the RX UE receives using a specific beam (i.e., the first beam). Alternatively, the specific beam may be a preset beam (e.g., an omni-directional beam), or a beam autonomously determined by the RX UE. Wherein the preset beam may be protocol agreed, control node configured or preconfigured.

In one possible implementation, the first rule may include: the first beam is used for receiving on the third target resource and/or the third beam is used for receiving on the fourth target resource. That is, in this possible implementation, the RX UE may employ a particular beam reception (e.g., omni-directional beam reception) on some preset resources (e.g., a third target resource, including time and/or frequency domain resources) and/or may employ an indicated beam (e.g., directional beam reception) on other preset resources (e.g., a fourth target resource).

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

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

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

Optionally, the fourth target resource comprises a dedicated resource for unicast transmission.

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

Optionally, the fourth target resource is a resource used for data transmission between the receiving terminal and the transmitting terminal, where the resource is negotiated between the receiving terminal and the transmitting terminal. For example, the RX UE and the TX UE may negotiate time domain and/or frequency domain resources used for data transmission between UEs-pair, so that the transmission of different TX UEs corresponding to the RX UE is TDM transmission, and the RX UE only needs to use one beam for reception at a time.

Optionally, the first beam may be a preset beam, for example, an omni-directional beam, or may also be a beam autonomously determined by the RX UE. Wherein the preset beam may be protocol-agreed, control node-configured, or pre-configured.

Alternatively, the third beam may be a beam indicated by the third beam indication information. The third beam indication information may be indicated by a control node (e.g., 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 TX UE indicates the first beam indication information, and specifically, refer to the description above about the TX UE indicating the first beam indication information.

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

In one possible implementation, the first rule may further include: in a case where the receiving terminal does not support reception on a fifth target resource using a plurality of beams and the receiving terminal is set to receive on the fifth target resource using a plurality of beams, the receiving terminal determines a reception beam in accordance with one of the following (1) to (4). The setting of the receiving terminal to receive on the fifth target resource by using multiple beams may be that the receiving terminal receives on the fifth target resource by using multiple beams by using a control node instruction, a sending terminal instruction, or a protocol agreement.

(1) Determining to preferentially adopt a beam corresponding to a first transmission and/or abandon a beam corresponding to a second transmission according to transmitted attribute information, wherein the attribute information comprises at least one of the following: priority information, quality of service (QoS) information. The QoS information may include reliability (reliability), delay (latency), packet Delay Budget (PDB), and the like.

For example, directional beams corresponding to low priority transmissions or low QoS transmissions (including transmissions of low reliability, transmissions of larger PDBs or remainning PDBs, etc.) are (preferentially) dropped.

Optionally, in this possible implementation, 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 that the receiving terminal intends to use a time domain and/or frequency domain resource that the sending terminal uses, where the time domain and/or frequency domain resource corresponds to a beam corresponding to the first transmission, and/or may also notify the sending terminal that the receiving terminal does not intend to use the time domain and/or frequency domain resource that the sending terminal uses, where the time domain and/or frequency domain resource corresponds to a beam corresponding to the second transmission.

(2) Receiving on the fifth target resource with a first beam.

Alternatively, the first beam may be a preset beam (e.g., an omni-directional beam), or a beam autonomously determined by the RX UE. Wherein the preset beams may be protocol-agreed/control node-configured/preconfigured.

(3) Receiving on the fifth target resource with a fifth beam, where the fifth beam is a beam indicated by beam indication information; for example, the RX UE preferentially receives on the fifth target resource using the indicated beam.

(4) And receiving on the fifth target resource by using a sixth beam, where the sixth beam is a beam with a larger number of corresponding transmitting terminals and/or a larger number of corresponding transport blocks. For example, the RX UE (preferentially) receives in the time domain and/or frequency domain resource (i.e., the fifth target resource) using the corresponding receiving beam with more TX UEs and/or more TB transmissions.

Alternatively, the RX UE may also be prevented from receiving on a time domain and/or frequency domain resource with multiple (directional) beams by negotiation between the RX UE and the TX UE or the proximity UE (e.g., negotiation of time domain and/or frequency domain resources for transmission between pair-UEs). I.e., the RX UE enables multiple (directional) receive beams in a TDM fashion.

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

Optionally, the preset reference direction comprises one of: a protocol agreed reference direction, a control node configured reference direction, a pre-configured reference direction. For example with some absolute direction as reference direction.

Optionally, determining the receive beam comprises at least one of:

determining a number of the receive beams;

determining a width of the receive beam;

determining a radiation pattern of the receive beam;

the number of the receive beams is determined, e.g. with the beam in the reference direction as the first number and the remaining beams clockwise.

Optionally, in the foregoing possible implementation manner, after the receiving terminal determines the receiving beam according to the first rule, the method further includes: the receiving terminal carries first information in a first signaling sent by the receiving terminal, wherein the first signaling is used for indicating and/or reserving a receiving resource, and the first information includes at least one of the following: beam information, location information of the receiving terminal. For example, the UE carries the beam information and/or the UE location information in the corresponding signaling (e.g., SCI) when performing the reception resource indication or reservation.

Optionally, in the foregoing possible implementation manner, before the receiving terminal determines the receiving beam according to the first rule, the method further includes: the receiving terminal selects a receiving resource according to the monitored second information, wherein the second information comprises at least one of the following information: the position information of the adjacent terminal, the beam indication information sent by the adjacent terminal and the resource occupation information of the adjacent terminal. For example, when the UE performs sending and reception resource selection, the resource selection is performed according to information such as detection/monitoring of beam indication information sent by the neighboring UE, and/or position information of the neighboring UE (or relative position information of the neighboring UE and the UE), and/or resource occupation of the neighboring UE.

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

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

By the technical scheme provided by the embodiment of the application, the receiving beam of the RX UE can be set, so that the RX UE can adopt receiving beams in multiple directions to receive the transmission of the sidelink, and the problems that the RX UE only adopts a certain directional RX beam to receive the transmission from a certain TX UE, the transmission from TX UEs in other directions cannot be received possibly, and the occupation condition of a channel cannot be accurately detected can be avoided.

Fig. 3 shows a flowchart of a data transmission method provided in an embodiment of the present application, where the method 300 may be executed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 3, the method may include the following steps.

S310, the transmitting terminal in the sidelink determines the transmitting beam of the target transmission.

In this embodiment, the sending terminal (TX UE) may be a relay terminal in the sidelink, or may be a remote terminal in the sidelink, and this embodiment is not limited in this application.

The Sidelink UE may employ a transceiver structure with multiple panels, and each panel may transmit/receive data in a direction of the beam corresponding to the particular direction. Therefore, in the embodiment of the present application, the TX UE determines the transmit beam of the target transmission before performing the target transmission.

S312, the transmitting terminal performs the target transmission on the secondary link by using the transmit beam.

Through the technical scheme provided by the embodiment of the application, the TX UE can perform target transmission by using beams, so that the path loss in sidelink transmission can be reduced, and the transmission signal strength is improved.

In one possible implementation, the determining, by the transmitting terminal, the transmission beam may include: the transmitting terminal determines to perform a Transport Block (TB) transmission in a resource set form; the transmitting terminal determines a transmission beam used by the target transmission based on at least one resource set.

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

Optionally, the sizes of the resources in the same resource set are the same, but certainly, the invention is not limited to this, and in a specific application, the sizes of the resources in the same resource set may also be different.

Optionally, the number of resources in one of the resource sets 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 of the sending terminal.

Alternatively, the resources in the set of resources may occur continuously in time. For example, it appears continuously on the sidelink slot of the resource pool and continuously on the local slot.

In the case that the resources in the resource set continuously appear in time, at least part of the resources in the resource pool are configured or preconfigured in the form of the resource set; or the sending terminal selects the resource set by taking the resource set as a basic unit for resource selection.

Alternatively, the resources in the set of resources may occur non-continuously in time. Alternatively, in this case, the transmitting terminal may select the resource set with a single resource as a basic unit of resource selection.

In one possible implementation manner, the transmission beam corresponding to the resource in the resource set includes one of: a preset transmission beam and a transmission beam autonomously determined by the transmission terminal. Optionally, the preset transmission beam may be protocol-agreed, control node-configured, or pre-configured.

Alternatively, the transmission beam pattern (e.g., beam scanning pattern) corresponding to the resource in the resource set includes one of: a preset transmission beam pattern, and a transmission beam pattern autonomously determined by the transmission terminal. Optionally, the preset transmission beam pattern may be protocol-agreed, configured by the control node, or preconfigured.

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

In the above possible implementation, one of the following may be agreed, configured by the control node, or pre-configured by the protocol:

(1) The first set of resources and the second set of resources; namely, protocol agreement, control node configuration or pre-configuration of which resource sets have quasi co-location relation of resource sending beams. For example, the resource transmission beams among the resource sets all have a quasi co-location relationship.

(2) A first resource in the first set of resources and a second resource in a second set of resources. I.e. protocol conventions, control node configuration, or pre-configuring which resources among the set of resources on which transmit beams have a quasi co-location relationship. For example, the transmission beams on the same numbered resources in the resource set have a quasi-co-location relationship.

In a possible implementation manner, a transmission beam corresponding to a sixth target resource in the at least one resource set is independently set with respect to transmission beams corresponding to other resources in the at least one resource set, where the sixth target resource is a resource occupied by third target information, and the third target information includes at least one of: resource reservation signaling, PSCCH, SCI. For example, the transmission beam of the "resource reservation signaling/control information/PSCCH/SCI/time domain and/or frequency domain resource occupied by a certain level of SCI" in the resource set may be set independently.

For example, the transmission beam corresponding to the sixth target resource is a first preset beam. That is, the transmission beam corresponding to the sixth target resource is a first preset beam, for example, an omni-directional beam.

Optionally, the resource reservation form indicated by the resource reservation signaling includes at least one of:

(1) Resources are reserved in the form of resource sets.

For example, (part of) the resources of the resource pool are configured in the form of resource sets, and as shown in fig. 4, any resource reservation signaling sent in a resource set indicates that the resource set is reserved.

Optionally, the reservation mode includes periodic reservation and aperiodic reservation; wherein the aperiodic reserved resource set is used for the same TB transmission and the periodically reserved resource set can be used for different TB transmissions.

(2) And reserving a third resource, wherein the third resource and a fourth resource occupied by the resource reservation signaling belong to the same resource set.

For example, as shown in fig. 5, the resource reservation signaling associated with a certain resource in the resource set reserves another resource in the resource set, so as to ensure resource reservation as much as possible and improve transmission reliability.

(3) And reserving fifth resources, wherein the fifth resources and fourth resources occupied by the resource reservation signaling belong to different resource sets.

For example, as shown in fig. 6, resource reservation signaling associated with a certain resource in a set of resources reserves a resource in another set of resources.

Optionally, the resources in the fifth resource set correspond to the fourth resource, or correspond to a transmission beam (e.g., a data transmission beam or a psch transmission beam) having a quasi-co-location relationship, so as to ensure directional resource reservation and improve space division utilization.

Optionally, the reservation mode includes periodic reservation and aperiodic reservation; wherein the aperiodic reserved set of resources is used for the same TB transmission and the periodic reserved set of resources can be used for different TB transmissions.
