In addition, the access device in this embodiment of the present application may be a device used to communicate with a terminal device, and the access device may also be referred to as an access network device or a wireless access network device, for example, the access device may be an LTE system The evolved base station (evolved NodeB, eNB or eNodeB) in the network can also be a wireless controller in a cloud radio access network (cloud radio access network, CRAN) scenario, or the access device can be a relay station, access point, Vehicle-mounted devices, wearable devices, access devices in future 5G networks or access devices in future evolved PLMN networks, etc., can be access points (access points, APs) in WLANs, or new wireless systems (new wireless systems). The gNB in the radio, NR) system is not limited in this embodiment of the present application.

In addition, in this embodiment of the present application, the access device is a device in the RAN, or in other words, is a RAN node that accesses the terminal device to the wireless network. For example, as an example and not a limitation, as an access device, it can be enumerated: gNB, transmission reception point (TRP), evolved Node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (for example, home evolved NodeB, or home Node B, HNB) , base band unit (base band unit, BBU), or wireless fidelity (wireless fidelity, Wifi) access point (access point, AP), etc. In a network structure, a network device may include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including a CU node and a DU node, or a control plane CU node (CU). - RAN equipment for CP nodes) and user plane CU nodes (CU-UP nodes) and DU nodes.

The access device provides services for the cell, and the terminal device communicates with the access device through the transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell, and the cell may correspond to the access device (for example, a base station). A cell. A cell can belong to a macro base station or a base station corresponding to a small cell. The small cell here can include: urban cell (metro cell), micro cell (micro cell), pico cell (pico cell), millicell Femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

In addition, a carrier in an LTE system or a 5G system can have multiple cells working on the same frequency at the same time. In some special scenarios, the concepts of the above-mentioned carrier and cell can also be considered equivalent. For example, in a carrier aggregation (CA) scenario, when a secondary carrier is configured for the UE, the carrier index of the secondary carrier and the cell identification (Cell ID) of the secondary cell operating on the secondary carrier will be carried at the same time. In this case, it can be considered that the concepts of the carrier and the cell are equivalent, for example, the terminal equipment accessing a carrier is equivalent to accessing a cell.

The communication system of the present application can also be applied to the vehicle to everything (V2X) technology, that is, the terminal device of the present application can also be a car, for example, a smart car or an autonomous car.

The "X" in V2X represents different communication targets. V2X can include but is not limited to: vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to network (vehicle to network, V2N), and vehicle to pedestrian (V2P).

In V2X, an access device can configure a "zone" for the UE. The area may also be referred to as a geographic area. When regions are configured, the world will be divided into multiple regions, which are defined by reference points, length, and width. When the UE determines an area identifier (identifier, ID), it will use the length and width of the area, the number of areas above the length, the number of areas above the width, and reference points to perform the remaining operations. The above information can be configured by the access device.

V2X services can be provided in two ways: namely, the way based on the PC5 interface and the way based on the Uu interface. The PC5 interface is an interface defined on the basis of a sidelink, and by using this interface, communication transmission can be directly performed between communication devices (eg, automobiles). The PC5 interface can be used outside of coverage (OOC) and in coverage (IC), but only authorized communication devices can use the PC5 interface for transmission.

In this application, V2X side link transmission supports two resource allocation modes, namely, dedicated resource mode (may be referred to as: mode1) and contention resource mode (may be referred to as: mode 2):

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 can perform resource allocation through the dedicated wireless network temporary identifier (radio network temporary identifier, RNTI) of the terminal device. As an example and not a limitation, in this application, the dedicated resource in the dedicated resource mode may include the SLDRX configuration.

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

For example, if the UE is configured with a mapping relationship from "service" to "reception configuration", the UE selects a corresponding resource pool according to the service configured by itself. The resource pool may also be called a resource set or a resource group, and a resource pool may include one or more resources, for example, V2X resources. Moreover, 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 the function of sensing. In addition, "monitoring" may also be referred to as measurement or detection. Based on the sensing result, the UE performs resource selection and reserves multiple resources.

In this application, the resource pool may refer to resources used for sidelink control information and data transmission.

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 resources may include resource blocks (RBs) RBs.

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

In this application, the first transmission mode may be defined by means of network device instructions, pre-configuration (for example, at the time of delivery or sale), or protocol provisions.

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

As an example and not a limitation, for example, the first transmission mode may correspond to a first sidelink resource configuration, wherein the resources in the first sidelink resource configuration are discontinuous resources (specifically, time domain In other words, the resources in the first sidelink resource configuration are part of the resources configured by the network device for the SL (specifically, part of the resources in the time domain). As an example and not a limitation, the resource corresponding to the first transmission mode may include but not limited to a resource pool, or a configured grant (CG) resource

For another example, the first transmission mode may correspond to the first sidelink discontinuous reception DRX configuration, where discontinuous reception (DRX, Discontinuous Reception) is a type of UE monitoring communication resources (for example, a control channel or a data channel). mechanism. If there is no DRX mechanism, the UE will always monitor the communication resources to check whether there is data transmission. When using DRX, the UE can periodically enter the sleep mode (sleep mode) at certain times. The UE does not need to continuously monitor the communication resources. The UE can achieve the purpose of power saving. It should be noted that, summarized in this application, the DRX configuration corresponding to the first transmission mode is the SL DRX configuration, that is, the DRX configuration used for the side link.

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

For another example, the first transmission mode may be pre-configured. For example, when the terminal device leaves the factory, the manufacturer or operator may pre-configure the information of the first transmission mode in the terminal device (for example, the configuration of SL resources or the configuration).

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 (eg, resource configuration or DRX configuration) when accessing the network.

It should be understood that the above-listed manners for the UE to know the first transmission mode are only exemplary descriptions, and the present application is not limited to this, as long as it is ensured that the UE can know 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 services or broadcast services. In other words, the first transmission mode is only used for the transmission of multicast or broadcast services.

It should be understood that the usage scenarios of the first transmission mode enumerated above are only exemplary descriptions, and the present application is not limited thereto, and the first transmission mode may also be used for the transmission of unicast services.

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 by the control information and the data may also be the same, which is not particularly limited in this application

In addition, in this application, the first transmission mode may be one type or multiple types (or include multiple configurations), which is not particularly limited in this application.

For example, when it is determined to use the first transmission mode to transmit services, different services may use the first transmission mode of the same configuration.

For another example, when it is determined to use the first transmission mode to transmit services, different services may use the first transmission modes with different configurations.

In this 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 any two different first transmission modes are different" can be understood as that the resource pools corresponding to any two different first transmission modes do not have overlapping parts.

Or, "the resource pools corresponding to any two different first transmission modes are different" can be understood as the resource pools corresponding to any two different first transmission modes partially overlap, that is, there is no overlapping part and non-overlapping parts.

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

FIG. 2 and FIG. 3 respectively show schematic interaction diagrams of an example of the wireless communication process of the present application.

When UE#2 (ie, an example of the second communication device) needs to send service #A (ie, an example of the first service) to other UEs, the process shown in FIG. 2 and/or FIG. 3 may be performed, wherein the Service #A may be a unicast service that needs to be sent to a terminal device, or, the service #A may also be a multicast or broadcast service that needs to be sent to multiple terminals, which is not particularly limited in this application. Below, for convenience It should be understood that the description will be given by taking the operation of UE#1 as the receiving end of the service #A as an example.

In addition, in this application, the service #A may be the service that the U#1 is interested in, or the service #A may be the service that UE#1 is configured to transmit.

As shown in FIG. 2, at S210, UE#2 generates information #A (ie, an example of the first information), where the information #A can be used to determine whether to use the above-mentioned first transmission mode to transmit a service (eg, service# A).

As an example and not limitation, the information #A includes but is not limited to the service identifier of service #A, the source identifier SRC ID of service #A, the destination identifier DST ID of service #A, and the transmission configuration Tx profile of service #A.

For example, the destination identifier DST ID includes the layer 2 destination identifier destination L2 ID or the layer 1 destination identifier destination L1 ID, and the source identifier SRC ID includes the layer 2 source identifier source L2 ID or the layer 1 source identifier source L1 ID.

In an implementation manner, UE#2 may also determine the transmission mode used when sending service #A according to information #A (for example, the transmission configuration Tx profile of service #A).

In this application, the Tx profile may include a version that supports the user energy saving feature, for example, R17, a new radio interface (New Radio, NR) R17, or a version after R17 that can support the UE energy saving feature.

Among them, the Tx profile of a service is R17, which can be understood as the transmission of the service in a manner corresponding to R17.

Alternatively, the Tx profile may include versions that do not support user power saving features, such as R14, R15 or R16.

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

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

In this application, the UE may have compatibility with the previous Tx profile, for example, a UE supporting R17 can also support using the corresponding manner of R14, R15 or R16 to transmit services.

In the following, in order to avoid redundant description, the description of the same or similar situations is omitted.

In one implementation, if the Tx profile of the service is R17, the first transmission mode is forced to transmit the service.

By way of example and not limitation, for example, if the Tx profile of service #A is R17, UE#2 uses the first transmission mode to send the service #A.

For another example, if the Tx profile of service #A is not R17, UE#2 does not use the first transmission mode to send this service #A.

In an implementation manner, UE#2 may use a second transmission mode to send the service #A. By way of example and not limitation, the second transmission mode may include a transmission mode without UE energy saving characteristics, for example, the second transmission mode The mode may be a prior art service transmission mode (eg, the transmission mode used by UEs whose device types are R14, R15, or R16). In another implementation manner, UE#2 may also determine the transmission used when sending service #A according to information #B (that is, information sent by multiple receiving UEs of the service #A including UE#1). mode, and subsequently, the process will be described in detail with reference to FIG. 3 .

It should be noted that, in this application, the transmission mode of the service #A determined by UE#2 and the transmission mode of the service #A determined by UE#1 may be the same or different, which is not particularly limited in this application.

In addition, in this application, the method and process for UE to determine the Tx profile of a service may be similar to the prior art. Here, in order to avoid repetition, the detailed description is omitted. For example, the UE may determine the Tx profile of the service according to high-level information of the service. profile, and the Tx profiles determined by different UEs for the same service may be the same or different, which is not particularly limited in this application.

At S220, UE#2 sends the information #A to UE#1 (ie, an example of the first communication device).

It should be noted that, in a 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 be outside the first transmission mode The information #A is transmitted in the transmission mode, which is not particularly limited in this application.

At S230, UE#1 determines whether to use the above-mentioned first transmission mode to receive the service #A according to the information #A.

In this application, the originating device of the service #A may be one device, that is, UE#2 (ie, case 1), or the originating device of the service #A may be multiple devices (including UE#2). device (ie, case two).

And, in case 2, the multiple devices all send information to UE#1 for determining whether to use the first transmission mode to transmit the service #A, and this process is similar to the process of UE#2 sending information #A, Here, in order to avoid redundant description.

First, the method and process of determining the transmission mode of service #A by UE#1 in a case are described in detail.

In one implementation, the information #A includes the Tx profile of service #A.

In addition, as described above, the Tx profiles 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 also determine the Tx profile of service #A based on information #A.

When the Tx profiles determined by different UEs for the same service are different, UE#1 determines the Tx profile of service #A based on information #A.

For example, when the Tx profile of service #A is a Tx profile with UE energy-saving features (for example, R17 or a version after R17 that supports UE energy-saving features), UE #2 can forcefully use the first transmission mode to receive service #A.

For another example, when the Tx profile of service #A is a Tx profile (for example, R14, R15, or R16) that does not have UE energy-saving features, UE #2 may determine not to use the first transmission mode to receive service #A, for example, use the first transmission mode to receive service #A. Two transmission modes (eg, prior art transmission modes) receive service #A. By way of example and not limitation, the second transmission mode may include the transmission mode currently used by UE#2.

For another example, when the Tx profile of service #A is a Tx profile (eg, R14, R15 or R16) that does not have the UE energy saving feature, UE #2 may disable the first transmission mode.

Wherein, disabling the first transmission mode may be understood as not using the first transmission mode when UE#1 receives the SL service.

As an example and not limitation, the SL service may include, but is not limited to, one or more of a sidelink multicast service, a sidelink broadcast service, or a sidelink unicast service.

The above-listed methods for determining the transmission mode based on the Tx profile are not limited to this in the present application. For example, in the present application, the information #A may also include, but is not limited to, the service identifier of the service #A, the source identifier SRC ID or The purpose identifies one or more of the DST IDs. Moreover, in this application, the above one or more identifiers can be used to instruct UE#2 to send the service #A. For example, in this application, the mapping relationship between multiple identities (or, in other words, identity groups) and multiple transmission modes may be preset, so that one or more identities carried by UE#1 information #A determine that UE#1 sends The transmission mode used for the service #A, or in other words, it is determined whether UE#1 uses the first transmission mode to send the service #A. In order to avoid redundant description, the description of the same or similar situations is omitted below.

Below, the method and process for UE#1 to determine the transmission mode of service #A in case 2 will be described in detail.

In one case, if the Tx profile of the service is R17, the first transmission mode is forced to transmit the service, that is, if the Tx profile of service #A is R17, then this first transmission mode is forced to transmit the service #A.

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

For example, when the Tx profiles of the same service determined by different UEs are the same, if the Tx profile of service #A is a Tx profile with UE energy saving features (for example, R17 or a version after R17 that supports UE energy saving features), UE# 2. It can be determined that service #A is received using the first transmission mode.

For another example, when the Tx profiles of the same service determined by different UEs are the same, if the Tx profile of service #A is a Tx profile (for example, R14, R15 or R16) that does not have the UE energy saving feature, UE #2 can determine Service #A is received using a first transmission mode, eg, service #A is received using a second transmission mode (eg, a prior art transmission mode).

For another example, when the Tx profiles of the same service determined by different UEs are the same, if the Tx profile of service #A is a Tx profile (for example, R14, R15 or R16) that does not have UE energy saving features, UE #2 can The first transmission mode is disabled.

For another example, when the 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 (that is, the Tx profile of service #A determined by the sending end UE). Tx profile).

For another example, if the Tx profile of service #A determined by some of the multiple originating UEs (at least one originating UE) is a Tx profile with UE energy saving features (for example, R17 or a version after R17 that supports UE energy saving features) , UE#2 may determine to use the first transmission mode to receive service #A.

For another example, if it is determined that the Tx profile of service #A is a Tx profile with UE energy-saving features (for example, R17 or a version after R17 that supports UE energy-saving features), the number of originating UEs is greater than or equal to the threshold 1, UE#2 can It is determined that the service #A is received using the first transmission mode.

For another example, if it is determined that the Tx profile of service #A is a Tx profile with UE energy-saving features (for example, R17 or a version after R17 that supports UE energy-saving features), the proportion of originating UEs is greater than or equal to threshold 2, UE#2 may It is determined that the service #A is received using the first transmission mode.

For another example, the information (for example, information #A) sent by the originating UE (for example, UE#2) also includes the location information of the originating UE. In this case, when UE#1 determines the Tx profile of all determined services #A If the distances between the originating UEs that are not R17 are all greater than or equal to the preset threshold 3, UE#1 uses the first transmission mode to receive the service #A.

It should be noted that, in this case, some originating UEs use the second transmission mode to send service #A, but UE#1 uses the first transmission mode to receive service #A, so UE#1 may not be able to receive service #A using the first transmission mode. The service #A (for example, data or control information) sent by the originating UE in the second transmission mode on all resources, or UE#1 cannot receive the service #A on a part of the time slot, in this case, by increasing the service The redundancy of #A (for example, the number of repeated transmissions is greater than a specified threshold) can allow UE#1 not to receive the service #A in some time slots; or, when the content of the service #A sent by multiple originating UEs is the same, UE#1 only needs to receive data of the originating device that uses the first transmission mode to send service #A in the first transmission mode. In the following, in order to avoid redundant description, the description of the same or similar situations is omitted.

In another implementation manner, the information #A may include the transmission mode determined by UE#2 to use when sending the service #A.

In this case, UE#1 can determine the transmission mode used when receiving service #A according to the transmission mode used when sending service #A determined by UE#2.

That is, in this case, if the Tx profile of service #A included in information #A is R17 (or the Tx profile of service #A determined by UE#2 is R17), then UE#2 can optionally use the first transmission mode to receive Service #A, or in other words, UE#2 can use the first transmission mode to receive service #A, and can also use other transmission modes to receive service #A.

Different UEs may use different transmission modes when sending service #A. In this case, the information #A includes the transmissions used by multiple sender UEs (including UE#2) of this service #A when sending this service #A. model.

For example, if some (at least one) of the multiple originating UEs use the first transmission mode to send the service #A, UE#2 may determine to use the first transmission mode to receive the service #A.

For another example, if all UEs in the multiple originating UEs do not use the first transmission mode (eg, use a transmission mode that does not support UE power saving features, that is, do not have a Tx profile that does not have UE power saving features (eg, R14, R15, or R16) ) corresponding transmission mode) When sending service #A, UE #2 may determine not to use the first transmission mode to receive service #A, for example, to use the second transmission mode (eg, the prior art transmission mode) to receive service #A.

For another example, if all UEs in the multiple originating UEs do not use the first transmission mode (eg, use a transmission mode that does not support UE power saving features, that is, do not have a Tx profile that does not have UE power saving features (eg, R14, R15, or R16) ) corresponding transmission mode) When sending service #A, UE #2 may disable (disable) the first transmission mode.

For another example, if the number of UEs using the first transmission mode to send service #A among the multiple originating UEs is greater than or equal to the threshold 4, UE #2 may determine to use the first transmission mode to receive service #A.

For another example, if the ratio of UEs sending service #A using the first transmission mode among the multiple originating UEs is greater than or equal to the threshold 5, UE #2 may determine to use the first transmission mode to receive service #A.

For another example, the information (for example, information #A) sent by the originating UE (for example, UE#2) also includes the location information of the originating UE. In this case, when UE#1 determines that it is compatible with all transmissions that do not use the first transmission mode If the distances between the originating UEs of service #A are all greater than or equal to the 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 use the first transmission mode to send the service #A is greater than or equal to the threshold 7, UE #2 does not use the first transmission mode to receive the service #A.

It should be noted that, in this case, some originating UEs use the second transmission mode to send service #A, but UE#1 uses the first transmission mode to receive service #A, so UE#1 may not be able to receive service #A using the first transmission mode. The service #A (for example, data or control information) sent by the originating UE in the second transmission mode on all resources, or UE#1 cannot receive the service #A on a part of the time slot, in this case, by increasing the service The redundancy of #A (for example, the number of repeated transmissions is greater than a specified threshold) can allow UE#1 not to receive the service #A in some time slots; or, when the content of the service #A sent by multiple originating UEs is the same, UE#1 only needs to receive data of part of the originating devices that use the first transmission mode to send service #A in the first transmission mode. In the following, in order to avoid redundant description, the description of the same or similar situations is omitted.

As shown in FIG. 3 , at S310, the receiving end UE#1 generates information #B (ie, another example of the first information).

Wherein, the information #B is used for UE#2 to determine the transmission mode used when sending a service (eg, service #A).

As an example and not a limitation, the information #B includes but is not limited to at least one of the following information:

Whether UE#1 supports the first transmission mode, whether UE#1 requests to adopt the first transmission mode, at least one of the device type of UE#1 and the device identity of UE#1.

As an example and not a limitation, the device identity of UE#1 may include, but is not limited to, layer 2 identity (L2 ID) of UE#1, source identity (SRC ID) of UE#1, member identity (member ID) of UE#1 , the local index of UE#1.

Therefore, UE#2 can determine the receiving end UE (eg, UE#1) of the service according to the device identifier carried in the information #B.

In this application, the device type includes a type that supports SL energy saving and a type that does not support SL energy saving.

S320, UE#1 sends information #B to UE#2.

In this application, the service sent by UE#2 may be a multicast service. In this case, there are multiple UEs at the receiving end of the service. In this case, each UE at the receiving end sends the above information to UE#2, In addition, this process is similar to the above-mentioned sending process of the information #B, and its detailed description is omitted here in order to avoid redundant description. Therefore, UE#2 can determine the receiver UE of the multicast service according to the device identifier carried in the information sent by each receiver UE.

Alternatively, the service sent by the UE#1 may be a unicast service, and in this case, there is only one UE at the receiving end of the service.

S330, UE#2 determines, according to information #B, whether to use the first transmission mode to send the service (for example, service #A), or in other words, UE#2 determines the transmission mode used when sending service #A, and sends the service based on the determined mode. Business #A.

For example, if UE#2 determines from the received one or more pieces of information #B that some (eg, at least one) or all of the UEs at the receiving end of the service support or request to use the first transmission mode, UE#2 may determine Service #A is sent using the first transmission mode.

Alternatively, if UE#2 determines, according to the received one or more pieces of information #B, that the number (or proportion) of UEs supporting or requesting to use the first transmission mode among the UEs at the receiving end of the service is greater than the threshold x, then UE#2 may It is determined that the service #A is sent using the first transmission mode.

For another example, if UE#2 determines according to the received one or more pieces of information #B that some (for example, at least one) or all of the device types in the UE at the receiving end of the service are types that support the first transmission mode (for example, R17 or a version after R17 that can support UE energy-saving features), and UE#2 determines that the Tx profile of service #A is a Tx profile with UE energy-saving features (for example, R17 or a version after R17 that supports UE energy-saving features) ), UE#2 can determine to use the first transmission mode to send service #A.

Or, if UE#2 determines, according to the received one or more pieces of information #B, the number (or ratio) of UEs whose device type is the type that supports the first transmission mode (for example, R17 or NR 17) in the UE at the receiving end of the service ) is greater than the threshold y, UE#2 may determine to use the first transmission mode to send service #A.

It should be noted that the methods shown in FIG. 2 and FIG. 3 can be used alone or in combination. For example, the generated information #A of UE#2 shown in FIG. 2 may include UE#2 shown in FIG. 3 . Information on the transmission mode used by the transmission service #A as determined by the process.

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

As shown in FIG. 4, S410, UE#A and UE#B determine the transmission configuration Tx profile of service #C (ie, an example of the first service).

In this application, the transmission configuration may be the transmission configuration of the NR R17 version that only supports the terminal equipment SL energy saving, which may be called the first transmission configuration; it may also be other transmission configurations that do not support the terminal equipment SL energy saving, such as NR R16, LTE R15 or R14, etc., may be referred to as the second transmission configuration.

Moreover, UE#A and UE#B determine whether to use the first transmission mode to receive the service according to the Tx profile of service #C, or UE#A and UE#B determine the transmission mode of service #C according to the Tx profile of service #C .

It should be noted that, in the solution shown in FIG. 4 , the transmission modes determined by different UEs according to the Tx profile are the same.

When the Tx profile of service #C is a Tx profile (for example, R17) with UE energy saving characteristics, UE #A and UE #B may determine to use the first transmission mode to receive service #C.

For another example, when service #C has a Tx profile (eg, R14, R15 or R16) that does not have the UE energy saving feature, UE#A and UE#B can disable the first transmission mode.

Wherein, disabling the first transmission mode can be understood as UE#A and UE#B do not use the first transmission mode when transmitting the SL service.

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

As shown in FIG. 5 , at S510, the transmitting end device UE#Y determines the 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 at least one service.

Wherein, the transmission mode includes a first transmission mode, that is, the transmission mode of at least one service in the multiple services is the first transmission mode that supports UE energy saving.

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

Alternatively, different services may use the first transmission modes with different configurations.

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 corresponding SL DRX configurations between any two different first transmission modes are different, and , the resource pools corresponding to the first transmission modes of different configurations may be the same, or the resource pools corresponding to the first transmission modes of different configurations may also be different. This application does not limit the characteristics.

As an example and not a limitation, the following manners for determining the first mapping relationship can be listed.

way 1

UE#Y may acquire the first mapping relationship from the network device.

Alternatively, the first mapping relationship may be pre-configured in UE#Y when UE#Y is shipped from the factory.

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

way 2

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 piece of information #C.

In an implementation manner, the information #C may include attribute information of the service, such as service quality configuration or service mode.

In another implementation manner, the information #C may further include information about resources used by the service, for example, the congestion rate or interference situation of the resources used by the service.

Therefore, UE#Y can determine the transmission mode corresponding to each service according to the information #C of each service.

For example, if the second mapping relationship indicates that the information #C of the service #X corresponds to the transmission mode #X, the UE#Y may determine that the transmission mode corresponding to the service #X in the first mapping relationship is the transmission mode #X.

way 3

Service #Y may determine the first transmission mode i∈[1,M] corresponding to the ith service according to the identifier of the ith service among the M services and the total number of the first transmission modes.

That is, the identifier of the i-th service and the total number of the first transmission modes are the arguments of function #1 (ie, an example of the first function), and the first transmission mode corresponding to the i-th service is the The dependent variable of the above function #1.

For example, the identifier of the i-th service includes the destination identifier DST ID of the i-th service.

As an example, the above function #1 can be expressed as:

n=x mode N

Wherein, the value of n is associated with the corresponding transmission mode of the i-th service, the value of x is associated with the identification of the i-th service, and the value of N is associated with the total number of the transmission modes.

S520, the sending end device UE#Y sends the relevant information of the first mapping relationship in the second transmission mode.

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

Alternatively, the related information of the first mapping relationship may include information for determining the first mapping relationship, such as the value of the above-mentioned function #1 or N, and the like.

Alternatively, the related information of the first mapping relationship may include attribute information of each service in the first mapping relationship. Moreover, when UE#X cannot obtain the second mapping relationship, the related information of the first mapping relationship may further include the second mapping relationship.

As an example and not a limitation, in this application, the network device may send the relevant information of the first mapping relationship through message #X, where the first message includes at least one of the following messages: a sidelink multicast radio resource control message, The sidelink broadcasts the radio resource control message, the sidelink medium access control control unit, and the sidelink system information.

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

S530, the receiving end device UE#X determines, according to the first mapping relationship, a transmission mode corresponding to the service #Y that it is interested in or is configured to transmit among the services included in the first mapping relationship.

At S540, UE#Y sends the service #Y according to the transmission mode corresponding to the service #Y, and UE#X receives the service #Y according to the transmission mode corresponding to the service #Y.

In a possible implementation manner, UE#Y may further update and modify the first mapping relationship, and send the updated first mapping relationship to UE#X.

Therefore, UE#Y sends the service #Y according to the transmission mode corresponding to the service #Y indicated by the updated first mapping relationship, and UE#X transmits the service #Y according to the transmission mode corresponding to the service #Y indicated by the updated first mapping relationship , receive service #Y.

It should be noted that, any modification method of UE#Y with respect to the first mapping relationship can be arbitrarily set by those skilled in the art, which is not particularly limited in this application.

As an example and not a limitation, the update opportunities of the first mapping relationship may be distributed periodically in the time domain. Specifically, in this application, a modification period may be defined, and the modification period is used to indicate the phase of the first mapping relationship. The time interval between two update opportunities of the neighbor.

In addition, in the same modification period, the modified first mapping relationship may be repeatedly sent, for example, each modification period may include multiple repetition periods, and the repetition periods are used to indicate the same first mapping relationship in the same modification period. The time interval between two adjacent receiver opportunities.

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

In an implementation manner, 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 an implementation manner, UE#Y may also send information #D (ie, an example of third information) to UE#X, where information #D is used to indicate that the first mapping relationship is updated.

As an example and not a limitation, the information #D may be carried in the first sidelink control information SCI.

For example, the first SCI may be an SCI dedicated to carrying the information #D.

Alternatively, the first SCI can also be used to carry information other than the information #D.

For example, the information #D may be transmitted in the first modification period among the plurality of modification periods, and the updated first mapping relationship is transmitted in the second modification period, and the first modification period is located in the first modification period. Before the second modification period, the modification period is used to indicate a time interval between two adjacent update opportunities of the first mapping relationship.
