The term "the first information is used to determine the transmission of the traffic using the first transmission mode" is also understood to mean that the first information is used to determine the mode used by the transmission of the traffic.

Alternatively, "the first information is used to determine to transmit the traffic using the first transmission mode" may also be understood as that the first information is used to determine whether to transmit the traffic using the first transmission mode.

For example, by way of illustration and not limitation, as access devices, there may be cited: a gNB, a transmission and reception point (transmission reception point, TRP), an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), or a wireless fidelity (wireless fidelity, wifi) Access Point (AP), etc. In one network architecture, the network devices may include Centralized Unit (CU) nodes, or Distributed Unit (DU) nodes, or RAN devices including CU nodes and DU nodes, or RAN devices including control plane CU nodes (CU-CP nodes) and user plane CU nodes (CU-UP nodes) and DU nodes.

The access device provides services for a cell, and the terminal device communicates with the access device through transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell, where the cell may be a cell corresponding to the access device (e.g., a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cells (metro cells), micro cells (micro cells), pico cells (pico cells), femto cells (femto cells) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission services.

In addition, the carrier wave in the LTE system or the 5G system may have multiple cells operating in the same frequency at the same time, and in some special scenarios, the carrier wave may be considered to be identical to the concept of the cell. For example, in the scenario of carrier aggregation (carrier aggregation, CA), when configuring a secondary carrier for a UE, the carrier index of the secondary carrier and the Cell identity (Cell indentification, cell ID) of the secondary Cell operating on the secondary carrier are carried at the same time, in which case the concept of the carrier and the Cell may be considered to be equivalent, such as that the terminal device accesses one carrier and accesses one Cell to be equivalent.

The communication system of the present application may also be adapted for internet of vehicles (vehicle to everything, V2X) technology, i.e. the terminal device of the present application may also be a car, e.g. a smart car or an autopilot car.

"X" in V2X represents a different communication target, and V2X may include, but is not limited to: automobile-to-automobile (vehicle to vehicl, V2V), automobile-to-road marking (vehicle to infrastructure, V2I), automobile-to-network (vehicle to network, V2N), and automobile-to-pedestrian (vehicle to pedestrian, V2P).

In V2X, the access device may configure a "zone" for the UE. Wherein the area may also be referred to as a geographic area. When the area is configured, the world will be divided into a number of areas, which are defined by reference points, length, width. When the UE determines a region Identifier (ID), the UE performs the remaining operations using the length, the width, the number of regions over the length, the number of regions over the width, and the reference point of the region. The above information may be configured by the access device.

The V2X service may be provided in two ways: namely, a PC5 interface-based system and a Uu interface-based system. Wherein the PC5 interface is an interface defined on a direct link (sidelink) basis, with which communication transmission can be directly performed between communication devices, such as automobiles. The PC5 interface may be used under out of coverage (OOC) and In Coverage (IC), but only authorized communication devices may use the PC5 interface for transmission.

In this application, V2X side-chain transmission supports two resource allocation modes, namely, a dedicated resource mode (which may be referred to as: mode 1) and a contention resource mode (which may be referred to as: mode 2):

wherein the dedicated resource mode requires the UE to be in a radio resource control (radio resource control, RRC) connected state. In this process, the network device may perform resource allocation by means of a dedicated radio network temporary identity (radio network temporary identifier, RNTI) of the terminal device. By way of example and not limitation, in the present application, dedicated resources in dedicated resource mode may include SL DRX configuration.

In addition, in the contention resource mode, the resources are configured by system message broadcast or dedicated signaling for the terminal devices in idle state, inactive state and connected state, and the resources can be shared by more than one terminal device. In contention resource mode, the UE can select transmission resources itself and adjust the transmission formats of control and data on the side chains.

For example, if the UE is configured with a mapping of "traffic" to "receive configuration", the UE selects a corresponding resource pool according to the traffic it is configured with. Wherein a resource pool may also be referred to as a set or group of resources, a resource pool may comprise one or more resources, e.g., V2X resources. And, the resource pool may be pre-configured by the access device for the UE. In addition, when selecting resources in the resource pool, the UE uses a monitoring (sensing) function, and "monitoring" may also be referred to as measurement or detection. Based on the result of the sending, the UE performs resource selection and reserves a plurality of resources.

In this application, the resource pool may refer to resources for control information and data transmission of side chains (sidelink).

Optionally, the resources in the resource pool include at least one of time domain resources, frequency domain resources, and time-frequency domain resources.

For example, the resource may include a Resource Block (RB) RB.

For another example, in V2X, a resource may include a subchannel formed of a plurality of RBs in succession, where the subchannel may be the smallest unit of scheduling/data transmission on a side chain (Sidelink).

In the present application, the first transmission mode may be defined by means of a network device indication, a pre-configuration (e.g. at the time of shipment or sale), or a protocol specification, etc.

The first transmission mode supports the UE energy saving characteristic, that is, energy consumption can be saved when the UE uses the first transmission mode to perform service transmission.

By way of example and not limitation, the first transmission mode may correspond to a first side-link resource configuration, wherein the resources in the first side-link resource configuration are non-contiguous resources (in particular non-contiguous resources in the time domain), or the resources in the first side-link resource configuration are part of the resources for SL (in particular part of the resources in the time domain) configured by the network device. By way of example and not limitation, the resources corresponding to the first transmission mode may include, but are not limited to, a resource pool, or a Configured Grant (CG) resource

As another example, the first transmission mode may correspond to a first side-link discontinuous reception, DRX, configuration, where discontinuous reception (DRX, discontinuous Reception) is one mechanism by which the UE listens to a communication resource (e.g., a control channel or a data channel). If there is no DRX mechanism, the UE will always monitor the communication resources to see if there is data transmission. When using DRX, the UE can periodically enter a sleep state (sleep mode), and the UE does not need to monitor communication resources continuously, but wakes up (wake up) from the sleep state when monitoring is needed, so that the UE can achieve the purpose of saving electricity. Note that, in summary of the present application, the DRX configuration corresponding to the first transmission mode is a SL DRX configuration, that is, a DRX configuration for a side uplink.

By way of example and not limitation, the first transmission mode may be indicated by the network device, i.e., the network device may broadcast information of the first transmission mode (e.g., configuration of resources or configuration of DRX).

As another example, the first transmission mode may be preconfigured, for example, information of the first transmission mode (for example, a configuration of SL resources or a configuration of SLDRX) may be preconfigured in the terminal device by a manufacturer or an operator at the time of shipment of the terminal device.

For another example, the first transmission mode may be specified by a protocol, for example, the terminal device may acquire information of the first transmission mode (for example, configuration of resources or configuration of DRX) when accessing the network.

It should be understood that the above-listed manner in which the UE learns the first transmission mode is merely an exemplary illustration, and the present application is not limited thereto, as long as it is ensured that the UE can learn the specific configuration of the first transmission mode in advance.

By way of example and not limitation, the first transmission mode may be a dedicated transmission mode for multicast traffic or broadcast traffic. In other words, the first transmission mode is only used for transmission of multicast or broadcast traffic.

It should be appreciated that the use scenario of the first transmission mode listed above is only an exemplary illustration, and the application is not limited thereto, and the first transmission mode may also be used for transmission of unicast traffic.

By way of example and not limitation, the first transmission mode includes a first data information transmission mode for transmitting data, and/or a first control information transmission mode for transmitting control information. Alternatively, the first transmission mode used for the control information and the data may be the same, and the present application is not particularly limited

In addition, in the present application, the first transmission mode may be one or multiple (or include multiple configurations), and the present application is not particularly limited.

For example, in determining to transmit traffic using the first transmission mode, different traffic may use the same configured first transmission mode.

As another example, in determining to transmit traffic using the first transmission mode, different traffic may use a differently configured first transmission mode.

In the present application, when the first transmission mode corresponds to the sidelink resource configuration, if the first transmission mode includes multiple configurations, the resource pools corresponding to any two different first transmission modes are different.

Here, "the resource pools corresponding to between any two different first transmission modes are different" may be understood as that the resource pools corresponding to between any two different first transmission modes do not have an overlapping portion.

Alternatively, "the resource pools corresponding to between any two different first transmission modes are different" may be understood as that the resource pools corresponding to between any two different first transmission modes are partially overlapped, i.e., have no overlapping portion and no overlapping portion.

In the present application, when the first transmission mode corresponds to the SL DRX configuration, if the first transmission mode includes a plurality of configurations, the corresponding SL DRX configuration between any two different first transmission modes is different.

In this application, when the first transmission mode corresponds to the SL DRX configuration and the sidelink resource configuration, if the first transmission mode includes multiple configurations, the SL DRX configurations corresponding to any two different first transmission modes are different, and the resource pools corresponding to the first transmission modes with different configurations may be the same.

The embodiment of the present application is not particularly limited to the specific structure of the execution body of the method provided in the embodiment of the present application, as long as it is capable of communicating in the method provided in accordance with the embodiment of the present application by executing a program recorded with a code of the method provided in the embodiment of the present application, for example, the execution body of the method provided in the embodiment of the present application may be a terminal device or a network device, or a functional module in the terminal device or the network device capable of calling the program and executing the program; or a component (e.g., a chip or circuit) that may be used in a terminal device or network device.

Furthermore, various aspects or features of the present application may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques. The term "article of manufacture" as used herein encompasses a computer program accessible from any computer-readable device, carrier, or media. For example, computer-readable media may include, but are not limited to: magnetic storage devices (e.g., hard disk, floppy disk, or magnetic tape, etc.), optical disks (e.g., compact Disk (CD), digital versatile disk (digital versatile disc, DVD), etc.), smart cards, and flash memory devices (e.g., erasable programmable read-only memory (EPROM), cards, sticks, key drives, etc.). Additionally, various storage media described herein can represent one or more devices and/or other machine-readable media for storing information. The term "machine-readable medium" can include, without being limited to, wireless channels and various other media capable of storing, containing, and/or carrying instruction(s) and/or data.

Fig. 2 and 3 are schematic interaction diagrams showing an example of a wireless communication process of the present application, respectively.

The procedure shown in fig. 2 and/or fig. 3 may be performed when the ue#2 (i.e., an example of the second communication device) needs to transmit the service #a (i.e., an example of the first service) to other UEs, wherein the service #a may be a unicast service that needs to be transmitted to one terminal device, or the service #a may be a multicast or broadcast service that needs to be transmitted to a plurality of terminals, which is not particularly limited in this application, and in order to facilitate understanding, an operation when the ue#1 is taken as a receiving end of the service #a will be described below as an example.

In addition, in the present application, the service #a may be a service of interest to the u#1, or the service #a may be a service that the ue#1 is configured to transmit.

As shown in fig. 2, at S210, the ue#2 generates information #a (i.e., an example of first information), which may be used to determine whether to transmit traffic (e.g., traffic #a) using the above-described first transmission mode.

By way of example and not limitation, the information #a includes, but is not limited to, a service identification of the service #a, a source identification SRC ID of the service #a, a destination identification DST ID of the service #a, and a transmission configuration Tx profile of the service #a.

In one implementation, ue#2 may also determine a transmission mode used when transmitting traffic #a according to information #a (e.g., a transmission configuration Tx profile of traffic #a).

In the present application, the Tx profile may include a version supporting the user power saving characteristics, for example, R17, a New Radio (NR) R17, or a version capable of supporting the UE power saving characteristics after R17.

The Tx profile of one service is R17, which can be understood that the service is transmitted in a manner corresponding to R17.

Alternatively, the Tx profile may include versions that do not support the user power saving feature, e.g., R14, R15, or R16.

In this application, when the Tx profile of a service is not R17, it is understood that the Tx profile of the service is R14, R15 or R16.

In addition, in the present application, the device type of the UE may be divided based on the Tx profile indicated by the UE, for example, the UE with the device type R17 may support traffic transmission in a manner corresponding to R17.

In the present application, the UE may have compatibility with the previous Tx profile, for example, the UE supporting R17 may also be able to support transmitting traffic using a corresponding manner of R14, R15 or R16.

Hereinafter, in order to avoid redundancy, the description of the same or similar cases will be omitted.

In one implementation, if the Tx profile of the traffic is R17, the traffic is forced to be transmitted using the first transmission mode.

By way of example and not limitation, if, for example, the Tx profile of traffic #a is R17, ue#2 transmits the traffic #a in the first transmission mode.

For another example, if the Tx profile of the traffic #a is not R17, the ue#2 does not transmit the traffic #a in the first transmission mode.

In one implementation, ue#2 may transmit the traffic #a using a second transmission mode, which may include a transmission mode without a UE power saving characteristic, for example, the second transmission mode may be a related art traffic transmission mode (e.g., a transmission mode used by a UE of a device type R14, R15, or R16). In another implementation, the ue#2 may also determine a transmission mode used when transmitting the service #a according to the information #b (i.e., information transmitted by a plurality of receiving UEs of the service #a including the ue#1), and the procedure will be described in detail with reference to fig. 3.

In the present application, the transmission mode of the service #a determined by the ue#2 may be the same or different from the transmission mode of the service #a determined by the ue#1, and the present application is not particularly limited.

In addition, in the present application, the method and procedure for determining Tx profile of one service by the UE may be similar to the prior art, and detailed description thereof is omitted herein for avoiding redundancy, for example, the UE may determine Tx profile of the service according to higher layer information of the service, and the Tx profiles determined by different UEs for the same service may be the same or different, which is not particularly limited in the present application.

In S220, ue#2 transmits the information #a to ue#1 (i.e., an example of the first communication apparatus).

It should be noted that, in one possible implementation manner of the embodiment of the present application, ue#1 and UE2 may transmit the information #a in the first transmission mode, or ue#1 may also transmit the information #a in a transmission mode other than the first transmission mode, which is not particularly limited in the present application.

In S230, the ue#1 determines whether to receive the service #a in the first transmission mode according to the information #a.

In this application, the originating device of the service #a may be one device, i.e., ue#2 (i.e., case one), or the originating device of the service #a may be a plurality of devices (including ue#2) (i.e., case two).

Also, in case two, the plurality of devices each transmit information for determining whether to transmit the service #a using the first transmission mode to the ue#1, and the procedure is similar to the procedure of transmitting the information #a by the ue#2, here, in order to avoid redundancy.

First, a method and procedure for determining a transmission mode of a service #a by the ue#1 in case will be described in detail.

In one implementation, the information #a includes Tx profile of traffic #a.

In addition, as described above, the Tx profile determined by different UEs for the same service may be the same or different.

When the Tx profiles determined by different UEs for the same service are the same, ue#1 may determine the Tx profile of service #a by itself, or ue#1 may determine the Tx profile of service #a based on information #a.

When the Tx profiles determined by different UEs for the same service are not the same, ue#1 determines the Tx profile of service #a based on information #a.

For example, when the Tx profile of the traffic #a is a Tx profile having the UE power saving characteristic (e.g., R17 or a version supporting the UE power saving characteristic after R17), the ue#2 may forcibly receive the traffic #a using the first transmission mode.

For another example, when the Tx profile of the traffic #a is a Tx profile (e.g., R14, R15 or R16) having no UE power saving characteristics, the ue#2 may determine not to receive the traffic #a using the first transmission mode, e.g., to receive the traffic #a using the second transmission mode (e.g., a transmission mode of the related art). By way of example and not limitation, the second transmission mode may include a transmission mode currently used by ue#2.

For another example, when the Tx profile of the traffic #a is a Tx profile (e.g., R14, R15 or R16) having no UE power saving characteristics, the ue#2 may disable the first transmission mode.

Disabling the first transmission mode may be understood as not being used by UE #1 when receiving SL traffic.

By way of example and not limitation, the SL traffic may include, but is not limited to, one or more of side-uplink multicast traffic, side-uplink broadcast traffic, or side-link unicast traffic.

The above-listed manner of determining the transmission mode based on Tx profile is not limited thereto, and for example, in the present application, the information #a may further include, but is not limited to, one or more of a service identifier of the service #a, a source identifier SRC ID, or a destination identifier DST ID. Also, in the present application, the one or more identifiers may be used to instruct ue#2 to transmit the service #a. For example, in the present application, a mapping relationship between multiple identifiers (or identifier groups) and multiple transmission modes may be preset, so that one or more identifiers carried by ue#1 information #a determine a transmission mode used when ue#1 transmits the service #a, or determine whether ue#1 transmits the service #a using the first transmission mode. In order to avoid redundancy, the description of the same or similar cases is omitted below.

Next, a method and procedure for determining the transmission mode of the service #a by the ue#1 in case two will be described in detail.

In one implementation, the information #a includes Tx profile of traffic #a.

In one case, if the Tx profile of the traffic is R17, the traffic is forcefully transmitted in the first transmission mode, i.e., if the Tx profile of the traffic #a is R17, the traffic #a is forcefully transmitted using the first transmission mode.

As described above, tx profiles of the same service determined by different UEs may be the same or different.

For example, when Tx profiles of the same service determined by different UEs are the same, if Tx profile of service #a is a Tx profile having UE power saving characteristics (e.g., R17 or a version supporting UE power saving characteristics after R17), ue#2 may determine to receive service #a using the first transmission mode.

For another example, when Tx profiles of the same service determined by different UEs are the same, if Tx profile of service #a is Tx profile (e.g., R14, R15 or R16) without the UE power saving characteristics, ue#2 may determine not to receive service #a using the first transmission mode, e.g., receive service #a using the second transmission mode (e.g., the transmission mode of the related art).

For another example, when Tx profiles of the same service determined by different UEs are the same, if Tx profile of service #a is Tx profile (e.g., R14, R15 or R16) without the UE power saving characteristics, ue#2 may disable the first transmission mode.

For another example, when Tx profiles of the same service determined by different UEs may be different, ue#1 is based on the Tx profile of service #a carried in the received information #a (i.e., the Tx profile of service #a determined by the transmitting UE).

For another example, if the Tx profile of the traffic #a determined by a part of the plurality of originating UEs (at least one originating UE) is the Tx profile having the UE power saving characteristics (e.g., R17 or a version supporting the UE power saving characteristics after R17), the ue#2 may determine to receive the traffic #a using the first transmission mode.

For another example, if it is determined that the Tx profile of the traffic #a is the number of originating UEs having the UE power saving characteristics (e.g., R17 or a version supporting the UE power saving characteristics after R17) is greater than or equal to the threshold 1, the ue#2 may determine to receive the traffic #a using the first transmission mode.

For another example, if it is determined that the Tx profile of the traffic #a is the proportion of the originating UE having the UE power saving characteristic (e.g., R17 or a version supporting the UE power saving characteristic after R17) is greater than or equal to the threshold 2, the ue#2 may determine to receive the traffic #a using the first transmission mode.

For another example, the information (for example, information #a) sent by the originating UE (for example, ue#2) further includes location information of the originating UE, in which case, when ue#1 determines that the distance between the originating UE and all originating UEs determining that Tx profile of the service #a is not R17 is greater than or equal to a preset threshold 3, ue#1 receives the service #a in the first transmission mode.

In this case, there is a case where a part of the originating UE transmits the traffic #a using the second transmission mode, but the ue#1 receives the traffic #a using the first transmission mode, and thus, there may be a case where the ue#1 cannot receive the traffic #a (e.g., data or control information) transmitted on all resources by the originating UE using the second transmission mode, or the ue#1 cannot receive the traffic #a on a part of the time slots, and in this case, it is possible to implement permission that the ue#1 does not receive the traffic #a on a part of the time slots by increasing redundancy of the traffic #a (e.g., the number of repeated transmissions is greater than a prescribed threshold value); or, when the contents of the service #a transmitted by the plurality of originating UEs are the same, the ue#1 only needs to receive the data of the originating device transmitting the service #a using the first transmission mode in the first transmission mode. Hereinafter, in order to avoid redundancy, the description of the same or similar cases will be omitted.

In another implementation, the information #a may include a transmission mode used when the ue#2 transmits the service #a.

In this case, the ue#1 may determine a transmission mode used when receiving the traffic #a according to a transmission mode used when transmitting the traffic #a determined by the ue#2.

That is, in this case, if the Tx profile of the traffic #a included in the information #a is R17 (or the Tx profile of the traffic #a determined by the ue#2 is R17), the ue#2 may selectively receive the traffic #a in the first transmission mode, or the ue#2 may receive the traffic #a in the first transmission mode, or may receive the traffic #a in other transmission modes.

The transmission modes used by different UEs when transmitting a service #a may be different, in which case the information #a includes the transmission modes used when a plurality of transmitting UEs (including ue#2) of the service #a transmit the service #a.

For example, if a portion (at least one) of the plurality of originating UEs transmits the traffic #a using the first transmission mode, the ue#2 may determine to receive the traffic #a using the first transmission mode.

As another example, if all UEs among the plurality of originating UEs do not transmit the traffic #a using the first transmission mode (e.g., using a transmission mode that does not support the UE power saving characteristics, i.e., a transmission mode corresponding to Tx profile (e.g., R14, R15, or R16) that does not have the UE power saving characteristics), the UE #2 may determine to receive the traffic #a without using the first transmission mode, e.g., using the second transmission mode (e.g., a transmission mode of the related art).

For another example, if all UEs among the plurality of originating UEs do not transmit the traffic #a using the first transmission mode (e.g., using a transmission mode that does not support the UE power saving characteristics, i.e., a transmission mode corresponding to Tx profile (e.g., R14, R15, or R16) that does not have the UE power saving characteristics), the UE #2 may disable the first transmission mode.

For another example, if the number of UEs transmitting traffic #a using the first transmission mode among the plurality of originating UEs is greater than or equal to the threshold 4, the ue#2 may determine to receive the traffic #a using the first transmission mode.

For another example, if the proportion of UEs among the plurality of originating UEs that transmit the traffic #a using the first transmission mode is greater than or equal to the threshold 5, the ue#2 may determine to receive the traffic #a using the first transmission mode.

For another example, the information (e.g., information #a) sent by the originating UE (e.g., ue#2) further includes location information of the originating UE, and in this case, when ue#1 determines that the distance between the originating UE and all originating UEs that do not use the first transmission mode to transmit the service #a is greater than or equal to a preset threshold 6, ue#1 uses the first transmission mode to receive the service #a.

For another example, if the number of originating UEs that do not transmit traffic #a in the first transmission mode is greater than or equal to the threshold 7, ue#2 does not receive the traffic #a using the first transmission mode.

In this case, there is a case where a part of the originating UE transmits the traffic #a using the second transmission mode, but the ue#1 receives the traffic #a using the first transmission mode, and thus, there may be a case where the ue#1 cannot receive the traffic #a (e.g., data or control information) transmitted on all resources by the originating UE using the second transmission mode, or the ue#1 cannot receive the traffic #a on a part of the time slots, and in this case, it is possible to implement permission that the ue#1 does not receive the traffic #a on a part of the time slots by increasing redundancy of the traffic #a (e.g., the number of repeated transmissions is greater than a prescribed threshold value); or, when the contents of the service #a transmitted by the plurality of originating UEs are the same, the ue#1 only needs to receive data of a part of the originating devices transmitting the service #a using the first transmission mode in the first transmission mode. Hereinafter, in order to avoid redundancy, the description of the same or similar cases will be omitted.

As shown in fig. 3, at S310, the receiving end ue#1 generates information #b (i.e., another example of the first information).

Wherein the information #b is used for the ue#2 to determine a transmission mode used when transmitting a service (e.g., service #a).

By way of example and not limitation, the information #b includes, but is not limited to, at least one of the following:

whether ue#1 supports the first transmission mode, whether ue#1 requests to employ at least one of the first transmission mode, the device type of ue#1, and the device identification of ue#1.

By way of example and not limitation, the device identification of ue#1 may include, but is not limited to, a layer 2 identification (L2 ID) of ue#1, a source identification (SRC ID) of ue#1, a member identification (member ID) of ue#1, a local index (local index) of ue#1.

Thus, ue#2 can determine the receiving end UE (e.g., ue#1) of the service according to the device identifier carried in the information #b.

In the present application, the device type includes a type supporting SL power saving and a type not supporting SL power saving.

S320, ue#1 transmits information #b to ue#2.

In this application, the service sent by the ue#2 may be a multicast service, in which case there are multiple receiving end UEs of the service, in which case each receiving end UE sends the above information to the ue#2, and the process is similar to the sending process of the above information #b, and detailed descriptions thereof are omitted here to avoid redundancy. Therefore, the ue#2 can determine the receiving end UE of the multicast service according to the device identifier carried in the information sent by each receiving end UE.

Alternatively, the service sent by the ue#1 may be a unicast service, in which case, the receiving UE of the service is one.

S330, the ue#2 determines whether to transmit a service (e.g., a service #a) in a first transmission mode according to the information #b, or, the ue#2 determines a transmission mode used when transmitting the service #a and transmits the service #a based on the determined mode.

For example, if ue#2 determines that part (e.g., at least one) or all of the receiving end UEs of the service support or request to use the first transmission mode according to the received one or more pieces of information #b, ue#2 may determine to transmit the service #a using the first transmission mode.

Alternatively, if the ue#2 determines that the number (or proportion) of UEs supporting or requesting to use the first transmission mode among the receiving end UEs of the service is greater than the threshold x according to the received one or more pieces of information #b, the ue#2 may determine to transmit the service #a using the first transmission mode.

For another example, if the ue#2 determines that a part (e.g., at least one) or all of the device types in the receiving end UE of the traffic are types supporting the first transmission mode (e.g., R17 or a version capable of supporting the UE power saving characteristics after R17) according to the received one or more pieces of information #b, and the ue#2 determines that Tx profile of the traffic #a is a Tx profile having the UE power saving characteristics (e.g., a version supporting the UE power saving characteristics after R17 or R17), the ue#2 may determine to transmit the traffic #a using the first transmission mode.

Alternatively, if the ue#2 determines that the number (or ratio) of UEs whose device type is a type supporting the first transmission mode (e.g., R17 or NR 17) in the receiving end UE of the service is greater than the threshold y according to the received one or more pieces of information #b, the ue#2 may determine to transmit the service #a using the first transmission mode.

It should be noted that the methods shown in fig. 2 and fig. 3 may be used alone or in combination, for example, the ue#2 shown in fig. 2 may include, in the generated information #a, information of a transmission mode used by the ue#2 to transmit the traffic #a determined in the procedure shown in fig. 3.

Fig. 4 is a schematic interaction diagram of another example of a wireless communication process of the present application.

As shown in fig. 4, at S410, ue#a and ue#b determine a transmission configuration Tx profile of traffic #c (i.e., an example of the first traffic).

In this application, the transmission configuration may be an NR R17 version of transmission configuration that only supports energy saving of the terminal device SL, and may be referred to as a first transmission configuration; other transmission configurations that do not support the power saving of the terminal device SL, such as NR R16, LTE R15, or R14, may also be referred to as a second transmission configuration.

And, ue#a and ue#b determine whether to receive the traffic in the first transmission mode according to Tx profile of traffic #c, or ue#a and ue#b determine the transmission mode of traffic #c according to Tx profile of traffic #c.

Note that, in the scheme shown in fig. 4, the transmission modes determined by different UEs according to Tx profile are the same.

When the Tx profile of the traffic #c is the Tx profile (e.g., R17) having the UE power saving characteristics, the UE #a and the UE #b may determine to receive the traffic #c using the first transmission mode.

For another example, when the Tx profile of the traffic #c is a Tx profile (e.g., R14, R15, or R16) having no UE power saving characteristics, the UE #a and the UE #b may determine not to receive the traffic #c using the first transmission mode, e.g., to receive the traffic #a using the second transmission mode (e.g., a transmission mode of the related art). By way of example and not limitation, the second transmission mode may include a transmission mode currently used by UE #a and UE #b.

For another example, when traffic #c is Tx profile (e.g., R14, R15, or R16) without the UE power saving feature, UE #a and UE #b may disable the first transmission mode.

Disabling the first transmission mode may be understood as not using the first transmission mode when UE #a and UE #b transmit SL traffic.

In S420, ue#a transmits traffic #c based on the determined transmission mode, and ue#b receives traffic #c based on the determined transmission mode.

Fig. 5 is a schematic interaction diagram of another example of a wireless communication process of the present application.

As shown in fig. 5, S510, the transmitting end device ue#y determines a first mapping relationship.

In this embodiment of the present application, the first mapping relationship is used to indicate a transmission mode corresponding to each service in at least one service.

Wherein the transmission mode includes a first transmission mode, that is, a transmission mode of at least one service of the plurality of services is a first transmission mode supporting UE power saving.

And, for example, different services may use the same configured first transmission mode.

Alternatively, different services may use different configurations of the first transmission mode.

In this application, when the first transmission mode corresponds to the SL DRX configuration and the sidelink resource configuration, if the first transmission mode includes multiple configurations, the SL DRX configurations corresponding to any two different first transmission modes are different, and the resource pools corresponding to the first transmission modes with different configurations may be the same, or the resource pools corresponding to the first transmission modes with different configurations may also be different, which is not limited by the characteristics of the present application.

By way of example, and not limitation, the following manner of determining the first mapping relationship may be cited.

Mode 1

The ue#y may acquire the first mapping relation from the network device.

Alternatively, the first mapping relationship may be preconfigured in the ue#y when the ue#y leaves the factory.

Alternatively, the first mapping relationship may be defined by a protocol.

Mode 2

The ue#y may acquire a second mapping relationship from the network device, where the second mapping relationship is used to indicate a transmission mode corresponding to at least one information #c.

In one implementation, the information #c may include attribute information of the service, such as a quality of service configuration or a service mode, etc.

In another implementation, the information #c may further include information about resources used by the service, for example, congestion rate or interference condition of the resources used by the service, etc.

Thus, the ue#y can determine a transmission mode corresponding to each service according to the information #c of each service.

For example, if the information #c of the second mapping relationship indicates that the traffic #x corresponds to the transmission mode #x, the UE #y may determine that the transmission mode corresponding to the traffic #x in the first mapping relationship is the transmission mode #x.

Mode 3

The service #Y can determine a first transmission mode i E [1, M ] corresponding to an ith service according to the identification of the ith service and the total number of the first transmission modes in M services.

That is, the identifier of the i-th service and the total number of the first transmission modes are arguments of a function #1 (i.e., an example of a first function), and the first transmission mode corresponding to the i-th service is an argument of the function # 1.

For example, the identification of the ith service includes a destination identification DST ID of the ith service.

By way of example and limitation, the function #1 described above may be expressed as:

n＝x mode N

wherein, the value of N is associated with the transmission mode corresponding to the ith service, the value of x is associated with the identification of the ith service, and the value of N is associated with the total number of the transmission modes.

S520, the transmitting terminal equipment UE#Y transmits the related information of the first mapping relation in the second transmission mode.

For example, the information related to the first mapping relationship may include the first mapping relationship itself.

Alternatively, the information related to the first mapping relationship may include information for determining the first mapping relationship, for example, the value of the function #1 or N described above, or the like.

Alternatively, the related information of the first mapping relationship may include attribute information of each service in the first mapping relationship. And, in case that the ue#x cannot obtain the second mapping relationship, the related information of the first mapping relationship may further include the second mapping relationship.

By way of example and not limitation, in the present application, the network device may send the related information of the first mapping relationship through a message #x, where the first message includes at least one of the following messages: a side-link multicast radio resource control message, a side-link broadcast radio resource control message, a side-link media access control unit, and side-link system information.

In the embodiment of the present application, the second transmission mode may include, but is not limited to, a transmission mode that does not support power saving of the terminal device SL.

S530, the receiving end equipment UE#X determines a transmission mode corresponding to the service #Y which is interested in or configured to be transmitted in the service included in the first mapping relation according to the first mapping relation.

In S540, the ue#y transmits the traffic #y according to the transmission mode corresponding to the traffic #y, and the ue#x receives the traffic #y according to the transmission mode corresponding to the traffic #y.

In one possible implementation, the ue#y may further update and modify the first mapping relationship, and send the updated first mapping relationship to the ue#x.

Thus, ue#y transmits the traffic #y according to the transmission mode corresponding to the traffic #y indicated by the updated first mapping relation, and ue#x receives the traffic #y according to the transmission mode corresponding to the traffic #y indicated by the updated first mapping relation.

It should be noted that, in the art, any modification manner of the ue#y with respect to the first mapping relationship may be arbitrarily set, and the present application is not particularly limited.

By way of example and not limitation, the update opportunities of the first mapping relation may be periodically distributed in the time domain, in particular, in the present application, a modification period may be defined, which is used to indicate a time interval of two adjacent update opportunities of the first mapping relation.

Also, the modified first mapping relationship may be repeatedly transmitted within the same modification period, for example, each modification period may include a plurality of repetition periods for indicating time intervals of two adjacent reception opportunities of the same first mapping relationship within the same modification period.

By way of example and not limitation, the modification period may be an integer multiple of the repetition period.

In one implementation, the boundary frame number between two adjacent modification periods may be determined based on the modification period and the first offset value.

For example, the modification period, the first offset value, and the boundary frame number between two adjacent modification periods satisfy the following formula:

y mod z＝w

In one implementation, the ue#y may further send information #d (i.e., an example of the third information) to the ue#x, where the information #d indicates that the first mapping relationship is updated.

By way of example and not limitation, the information #d may be carried on the first side-link control information SCI.

For example, the first SCI may be a SCI dedicated to carrying the information #d.

Alternatively, the first SCI may be used to carry information other than the information #d.

For example, the information #d may be transmitted in a first modification period of a plurality of modification periods, the updated first mapping relationship may be transmitted in a second modification period, the first modification period being located before the second modification period, the modification period being used to indicate a time interval of two adjacent update opportunities of the first mapping relationship.

Fig. 6 is a schematic interaction diagram of another example of a wireless communication process of the present application.

As shown in fig. 6, S610, the receiving end device ue#z and the transmitting end device ue#w determine a first mapping relationship.

In this embodiment of the present application, the first mapping relationship is used to indicate a transmission mode corresponding to each service in the plurality of services.

And when the first transmission modes include a plurality of configurations, the corresponding resource pools between any two different first transmission modes are different.

Alternatively, the corresponding SL DRX configuration between any two different first transmission modes is different.

The ue#z and the ue#w may determine a first transmission mode i e [1, M ] corresponding to an ith service according to an identification of the ith service and a total number of the first transmission modes in the M services.

n＝x mode N

In S620, the ue#z transmits the service #y according to the transmission mode corresponding to the service #z, and the ue#w receives the service #z according to the transmission mode corresponding to the service #z, where the service #z may be a service in which the ue#w is configured to receive, or the service #z may be a service in which the ue#w is interested.

Fig. 7 is a schematic interaction diagram of another example of a wireless communication process of the present application.

As shown in fig. 7, ue#a transmits a first message to ue#b using a first transmission mode.

The first transmission mode comprises the transmission mode supporting the energy-saving characteristic of the terminal equipment.

And, ue#a is a new SL initiator, and ue#b is a new SL receiver.

In an embodiment of the present application, the first message is a message for requesting establishment of a side uplink.

In the present application, the first message includes a direct communication request (Direct Communication Request) or a direct link establishment request (Direct link establishment request).

In one possible implementation, ue#a may start the customizer after sending the first message and keep the active (or awake) state until the timer expires in order to receive the response message sent by ue#b for the first message.

It should be noted that if the above response message is not received after the timer expires, it indicates that ue#a may not expect the reply of ue#b any more. In this case, the ue#a may enter a sleep state to save power consumption.

And, ue#b transmits a second message to ue#a using a second transmission mode.

And, ue#a transmits a third message to ue#b using the second transmission mode.

The second transmission mode includes a transmission mode that does not support energy saving of the terminal device SL.

By way of example and not limitation, the second message and the third message may include messages in the process of establishing a side uplink.

And, the establishing a side-link procedure may include, but is not limited to, at least one of:

side link direct link establishment (sidelink Direct link establishment), side link direct link security mode control (sidelink Direct link Security Mode controlling), side link direct link authentication (sidelink Direct link authentication), side link user capability exchange (sidelink UE capability transfering), side link radio resource reconfiguration (sidelink RRC reconfiguration), side link unicast link establishment (sidelink unicast link establishment), side link unicast link security mode control (sidelink unicast link Security Mode control), side link unicast link authentication (sidelink unicast link authentication), PC5 direct link establishment (PC 5 Direct link establishment), PC5 direct link security mode control (PC 5 Direct link Security Mode control), PC5 direct link authentication (PC 5 Direct link authentication), PC5 user capability exchange (PC 5 UE capability transfering), PC5 radio resource reconfiguration (PC 5 RRC reconfiguration), PC5 unicast link establishment (PC 5 unicast link establishment), PC5 unicast link security mode control (PC 5 unicast link Security Mode control), PC5 unicast link authentication (PC 5 unicast link authentication).

That is, the second message includes at least one of:

a direct link security mode indication message (Direct link Security Mode Command), a direct link establishment acceptance message (Direct link establishment accept), sidelink user capability information (UE capability information sidelink), and a sidelink radio resource control reconfiguration complete message (sidelink RRC reconfiguration complete).

The third message includes at least one of:

direct security mode complete message (Direct Security Mode Complete), side-uplink user capability query message (sidelink UE capability enquiry), side-uplink radio resource control reconfiguration message (sidelink RRC reconfiguration), PC5 user capability query message (PC 5 UE capability enquiry), PC5 radio resource control reconfiguration message (PC 5 RRC reconfiguration).

In one possible implementation, the second message may also carry the SL DRX configuration currently used by UE #b.

And, the first message may also carry the SL DRX configuration currently used by the ue#a.

In addition, the SL DRX configuration currently used by the UE may be determined from candidate SL DRX configurations, which may include, but are not limited to, a unicast SL DRX configuration, a multicast SL DRX configuration, or a broadcast SL DRX configuration, etc. Fig. 8 is a schematic interaction diagram of another example of a wireless communication process of the present application. Unlike the process shown in fig. 7, in the process shown in fig. 8, part(s) of the second message is (are) also transmitted through the first transmission mode.

And, part(s) of the message(s) in the third message are also transmitted via the first transmission mode.

Fig. 9 is a schematic interaction diagram of another example of a wireless communication process of the present application. Unlike the procedure shown in fig. 7 and 8, in the procedure shown in fig. 9, ue#n and ue#m determine whether the state of the first transmission mode satisfies a preset condition.

For example, the state of the first transmission mode may include an attribute (e.g., CMR) of a resource pool corresponding to the first transmission mode, in which case, ue#n and ue#m may determine whether the CMR of the resource pool corresponding to the first transmission mode is lower than a threshold s, and if so, ue#n and ue#m may transmit other messages than the first message in the establishment of the side uplink using the first transmission mode; if the determination is negative, the ue#n and the ue#m may transmit the second message and the third message based on the manner shown in fig. 7 or fig. 8.

For another example, the state of the first transmission mode may include an attribute (for example, CBR) of a resource pool corresponding to the first transmission mode, in which case, ue#n and ue#m may determine whether the reception performance on the configuration corresponding to the first transmission mode is greater than a threshold t, and if yes, ue#n and ue#m may transmit other messages than the first message in the establishment of the side uplink using the first transmission mode; if the determination is negative, the ue#n and the ue#m may transmit the second message and the third message based on the manner shown in fig. 7 or fig. 8.

Note that "side link" (or "sidlink") in each message name in the present embodiment may be replaced with "PC5". And these message or signaling procedure names are used to indicate functions of the corresponding messages or procedures, messages or procedures corresponding to the exact same names are not limited.

Fig. 11 is a schematic structural diagram of a communication device 1100 provided in the present application. The apparatus 1100 may be configured in the communication device 1100, or the apparatus 1100 itself may be the communication device 1100. Alternatively, the communication device 1100 may perform the actions performed by the communication device in the method 1100 described above.

For ease of illustration, fig. 11 shows only the main components of the communication device. As shown in fig. 11, the communication apparatus 1100 includes a processor, a memory, a control circuit, an antenna, and an input-output device.

The processor is mainly configured to process the communication protocol and the communication data, and control the entire communication device, execute a software program, and process the data of the software program, for example, to support the communication device to perform the actions described in the above-mentioned method embodiments for indicating the transmission precoding matrix. The memory is mainly used for storing software programs and data, for example, for storing the codebook described in the above embodiments. The control circuit is mainly used for converting baseband signals and radio frequency signals and processing the radio frequency signals. The control circuit together with the antenna, which may also be called a transceiver, is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used for receiving data input by a user and outputting data to the user.

When the communication device is started, the processor can read the software program in the storage unit, interpret and execute the instructions of the software program, and process the data of the software program. When data is required to be transmitted wirelessly, the processor carries out baseband processing on the data to be transmitted and then outputs a baseband signal to the radio frequency circuit, and the radio frequency circuit carries out radio frequency processing on the baseband signal and then transmits the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is transmitted to the communication device, the radio frequency circuit receives a radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor, and the processor converts the baseband signal into data and processes the data.

For example, the processor may include a baseband processor, which is mainly used to process the communication protocol and the communication data, and a central processor, which is mainly used to control the entire communication device, execute a software program, and process the data of the software program. The processor in fig. 11 integrates the functions of a baseband processor and a central processing unit, and those skilled in the art will appreciate that the baseband processor and the central processing unit may be separate processors, interconnected by bus technology, etc. Those skilled in the art will appreciate that a communication device may include multiple baseband processors to accommodate different network formats, and that a communication device may include multiple central processors to enhance its processing capabilities, with various components of the communication device being connectable via various buses. The baseband processor may also be expressed as a baseband processing circuit or a baseband processing chip. The central processing unit may also be expressed as a central processing circuit or a central processing chip. The function of processing the communication protocol and the communication data may be built in the processor, or may be stored in the storage unit in the form of a software program, which is executed by the processor to realize the baseband processing function.

For example, in the embodiment of the present application, the antenna and the control circuit having the transceiving function may be regarded as the transceiving unit 1110 of the communication device 1100, and the processor having the processing function may be regarded as the processing unit 1120 of the communication device 1100. As shown in fig. 1100, the communication device 1100 includes a transceiving unit 1110 and a processing unit 1120.
