For a better understanding, the following describes related technologies and concepts that may be involved in the embodiments of the present application.

New air interface (New Radio, NR) secondary link (Sidelink, SL) resource selection

There are two ways to allocate NR sidelink resources, one is based on base station scheduling (mode 1, mode1), and the other is based on UE autonomous selection (mode2). For the resource allocation method scheduled by the base station, the sidelink resources used by the UE for data transmission are determined by the base station, and the sending terminal (Transport UE, TX UE) is notified through downlink signaling; for the resource allocation method independently selected by the UE, the UE is in (pre-) Select available transmission resources from the configured resource pool, UE performs channel monitoring before resource selection, selects a resource set with less interference according to the result of channel sensing (sensing), and then randomly selects a resource set for transmission from the resource set resource.

For mode 2, the specific working method is as follows:

1) When the TX UE performs resource selection, the Medium Access Control (MAC) layer provides resource selection-related parameters to the physical layer. The parameters include resource selection trigger time (such as time slot, slot_n), remaining packet delay budget ( remaining packet delay budget, remaining PDB), priority (priority), number of sub-channels (number of sub-channel) and resource reservation interval (resource reservation interval), etc. After the physical layer obtains the relevant parameters of resource selection, it first determines the resource selection Window, the lower boundary of the resource selection window is at T1 time after slot_n, and the upper boundary of the resource selection window is at T2 time of slot_n, where T2 is selected in the remaining PDB of the transmission block (Transport Block, TB) transmission by the UE value, T2 is not earlier than T1.

2) Before resource selection, the UE needs to determine the candidate resource set (candidate resource set) for resource selection, according to the reference signal received power (ReferenceSignal Received Power, RSRP) measured on the resource within the resource selection window and the corresponding RSRP threshold ( threshold) for comparison, if the RSRP is higher than the RSRPthrehold, then the resource is excluded and cannot be included in the candidate resource set. After resource exclusion, the remaining resources in the resource selection window form the candidate resource set. The resources in the candidate resource set must account for no less than x% of the resources in the resource selection window. If it is less than x%, the RSRP threshold needs to be increased according to the step value (for example, 3dB), and then the resources are excluded Operates until no less than said x% of resources can be selected.

3) After the candidate resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. In addition, the UE may reserve transmission resources for the next transmission in this transmission.

NR sidelink resource selection enhancements

Rel-17 NR SL enhancement (enhancement) WI is discussing an enhancement scheme for resource allocation. The enhancement scheme is divided into scheme 1 and scheme 2.

For scheme 1, UE-A decides a resource set, UE-A sends coordination signaling (coordination signaling) to recommend the resource set to UE-B, and UE-B can consider the resource set recommended by UE-A when performing resource selection . Wherein, the resource in the resource set can be "the transmission resource that UE-A prefers to use by UE-B (that is, the preferred resource set)", or "the transmission resource that UE-A does not prefer to use by UE-B (that is, the non-preferred resource set) ".

For the transmission of coordination signaling, request-based coordination signaling (request-based coordination signaling) transmission and condition-based coordination signaling (condition-based coordination signaling) transmission are supported. For request-based coordination signaling transmission, UE-B sends request signaling (request signaling), and UE-A triggers coordination signaling transmission after receiving request signaling. For the condition-based coordination signaling transmission, UE-A triggers the coordination signaling transmission when the preset condition is satisfied.

The transmission method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

Please refer to Figure 2, Figure 2 is a flow chart of a transmission method provided in the embodiment of the present application, as shown in Figure 2, the transmission method includes the following steps:

Step 201: The terminal transmits target information on the PSSCH, or,

The terminal transmits target information on the PSSCH, and multiplexes high layer data except the target information on the PSSCH.

Wherein, the quantity of the target information is at least one, and the target information includes at least one of the following:

Medium Access Control Control Element (MAC CE) carrying request information;

MAC CE carrying coordination information;

Second stage sidelink control information (Sidelink Control Information, SCI) carrying request information;

Phase 2 SCI carrying coordination information;

Padding data for resource selection triggering request signaling;

Padding data for resource selection that triggers coordination signaling.

For example, the target information includes a MAC CE carrying request information (request information), that is, the request information and the MAC CE can be multiplexed on a Physical SideLink Shared Channel (PSSCH) for transmission, and terminal A can The method is to send the MAC CE carrying the request information to the terminal B as request signaling (request signaling). Alternatively, the target information includes a MAC CE carrying coordination information, that is, the coordination information and the MAC CE can be multiplexed on the PSSCH for transmission, and terminal A can use the MAC CE carrying the coordination information as coordination signaling (coordination signaling) is sent to terminal B.

Optionally, the request information or coordination information can also be carried in the second stage (2 ^nd stage) SCI. In this case, the 2 ^nd stage SCI can also be used as request signaling or coordination signaling by terminal A on PSSCH and send it to Terminal B. Alternatively, the target information may include stuffing data used to trigger resource selection for request signaling, which is sent by terminal A to terminal B on the PSSCH; or, the target information includes stuffing data used to trigger resource selection for coordination signaling, which is sent by terminal A to terminal B on the PSSCH; Terminal A sends to terminal B on the PSSCH.

It should be noted that the terminal A and the terminal B in the embodiments of the present disclosure are only examples and not specific. In some scenarios, the terminal B may also send the above target information to the terminal A. For example, terminal A can send a request signaling to terminal B, and terminal B sends a coordination signaling to terminal A after receiving the request signaling; in another scenario, terminal B can also send a request signaling to terminal A, and terminal After receiving the request signaling, A sends a coordination signaling to terminal B.

In the embodiment of the present application, the terminal transmits target information on the PSSCH, for example, one or more target information; and the target information includes at least one of the following: MAC CE carrying request information, MAC CE carrying coordination information, MAC CE carrying request information 2 ^nd stage SCI, 2 ^nd stage SCI carrying coordination information, padding data used to trigger resource selection of request signaling, padding data used to trigger resource selection of coordination signaling, so that request information or coordination information can be It is multiplexed with other data and transmitted on the same PSSCH, so that the PSSCH that transmits request information (or request signaling) and coordination information (or coordination signaling) can also multiplex other transmission information, which can effectively improve the information in the communication system Transmission efficiency, improve the utilization rate of the transmission channel.

In addition, the terminal transmits at least one target information on the PSSCH, and can multiplex high-level data other than the target information on the PSSCH, so that the PSSCH can not only transmit target information, but also transmit other high-level data, Effectively improve transmission efficiency.

Wherein, when the number of target information transmitted by the terminal on the PSSCH is multiple, the multiple target information may be the same or different, for example, one of the target information is the MAC CE including the request information, and the other The target information is padding data used to trigger coordination signaling. Optionally, which target information the terminal transmits on the same PSSCH may be agreed upon, configured or pre-configured.

It should be noted that the terminal may also transmit the above-mentioned target information on a physical side link control channel (Physical SideLink Control Channel, PSCCH), which can achieve the same technical effect as that transmitted on the above-mentioned PSSCH. In the subsequent embodiments, only the transmission of the target information on the PSSCH will be described in detail, but all the solutions that can be implemented on the PSSCH in the subsequent embodiments can also be implemented on the PSCCH. To avoid redundant description, the PSCCH will not be described separately. .

In the embodiment of the present disclosure, before transmitting the target information, the terminal may first determine whether the transmitted information is the target information, and then execute the transmission of the target information if the transmitted information is the target information. Optionally, when the information transmitted by the terminal is the target information, the terminal transmits the target information on the PSSCH, and does not multiplex high-level data other than the target information on the On the PSSCH, that is, the terminal only transmits target information on the PSSCH. For example, if the target information transmitted on the PSSCH includes the MAC CE carrying the request information, other high-level data such as other MAC CEs cannot be multiplexed on the PSSCH for transmission except for the MAC CE carrying the request information, so as to ensure The reliability of the target information transmission.

Optionally, the terminal transmits target information on the PSSCH, including:

If the information transmitted by the terminal is the target information, and the target information is only physical layer information, the terminal transmits only the target information on the PSSCH.

It should be noted that when the target information transmitted by the terminal on the PSSCH is only physical layer information, such as 2 ^nd stage SCI including request information, and/or 2 ^nd stage SCI including coordination information, in this case, the terminal transmits on the PSSCH Only the target information is transmitted on the PSSCH, and the terminal cannot multiplex high-level data (high layers including the MAC layer and above layers) other than the target information on the PSSCH, so as to ensure that the priority of PSSCH transmission is not lower than the target information priority. It should be noted that physical layer data other than target information can be multiplexed on the PSSCH, or cannot be multiplexed on the PSSCH.

Optionally, the priority corresponding to the target information is associated with the priority corresponding to the target transport block (Transport Block, TB).

It should be noted that the target TB is a TB that the terminal will transmit on a preferred resource (preferred resource), or a TB associated with the preferred resource; and/or, the target TB is a TB that triggers the terminal to request the preferred resource.

Wherein, the priority corresponding to the target TB is the priority used when another terminal selects a preferred resource. For example, the terminal is terminal B, and the target TB can be the TB that terminal B will transmit in the preferred resource, or the TB that triggers terminal B to request the preferred resource, then the priority corresponding to the target TB is that terminal A selects preferred The priority used when resource.

In the embodiment of the present disclosure, the priority corresponding to the target information is associated with the priority corresponding to the target TB, that is, there is an association relationship. Optionally, the association relationship includes at least one of the following:

A priority corresponding to the target information is associated with a priority corresponding to the target transport block;

A priority corresponding to one target information is associated with priorities corresponding to at least two target transport blocks;

At least two priorities corresponding to the target information are associated with a priority corresponding to one target transport block.

For example, the priority corresponding to the target information and the priority corresponding to the target TB are in a one-to-one relationship, for example, the priority corresponding to the target information is 1, and the priority corresponding to the target TB is 1. Or, the priority corresponding to the target information and the priority corresponding to the target TB is a one-to-many relationship, for example, the priority corresponding to the target information is 0, the priority corresponding to the target TB-1 is 1, and the priority corresponding to the target TB-2 The priority is 2, and the target information may be associated with target TB-1 and target TB-2. Alternatively, the priority corresponding to the target information and the priority corresponding to the target TB may also be a many-to-one relationship, the priority corresponding to the target information-1 is 0, the priority corresponding to the target information-2 is 1, and the priority corresponding to the target information- The priority corresponding to 3 is 2, the priority corresponding to a certain target TB is 3, and the target information-1, target information-2, and target information-3 may all be associated with the target TB.

It should be noted that the priority corresponding to the target information may be the same as the priority corresponding to the target TB.

Optionally, in the case where the PSSCH transmits at least two pieces of the target information, and high-layer data other than the target information is not multiplexed on the PSSCH, the first phase of the PSSCH transmission (1 ^st stage) The priority of the SCI is the first priority, and the first priority is the highest priority corresponding to the at least two target information, that is, the highest priority among the priority corresponding to the at least two target information The priority is set to the priority of the ^1st stage SCI.

Optionally, in the case of multiplexing high-level data other than the target information on the PSSCH, the priority of the first-stage SCI of the PSSCH transmission is the second priority, and the second priority The level is the highest priority corresponding to the high-level data transmitted in the PSSCH except the target information, that is, the highest priority corresponding to the high-level data transmitted on the PSSCH except the target information is set to the Describe the priority of ^1st stage SCI.

It should be noted that when the target information is only physical layer information, and high-layer data other than the target information is multiplexed on the PSSCH, the priority of the SCI in the first stage of the PSSCH transmission is the The above-mentioned second priority, that is, the corresponding highest priority among the high-level data transmitted on the PSSCH except the target information. In this way, it is also possible to prevent the terminal from generating too much target information and carrying low-priority data, and avoid reducing the transmission efficiency of the system.

Optionally, the terminal transmits target information on the PSSCH, and multiplexes high-layer data other than the target information on the PSSCH, including any of the following:

The terminal transmits at least one target information on the PSSCH, and multiplexes high-level data with a priority lower than or equal to the priority corresponding to the at least one target information on the PSSCH;

The terminal transmits at least one target information on the PSSCH, and multiplexes high-layer data with a priority higher than or equal to the priority corresponding to the at least one target information on the PSSCH;

The terminal transmits at least one target information on the PSSCH, and when the at least one target information is high-level information, multiplexes high-level data other than the at least one target information on the PSSCH;

When the terminal outputs at least one target information on the PSSCH, and the target transmission end of the high layer data other than the at least one target information is the same as the target transmission end of the at least one target information, the at least one High layer data other than target information is multiplexed on the PSSCH.

For example, the terminal only multiplexes high-layer data with a priority lower than or equal to the corresponding priority of the target information on the PSSCH transmitting the target information, and then the priority in the ^1st stage SCI is directly used to indicate the target information corresponding to Priority, no additional field is required to indicate the priority of the target information.

Alternatively, the terminal only multiplexes high-level data with a priority higher than or equal to the corresponding priority of the target information on the PSSCH for transmitting the target information, so that the transmission of the target information can be protected and the validity of the target information transmission can be ensured .

Or, only when the target information is high-level information, the terminal multiplexes high-level data other than the target information on the PSSCH for transmitting the target information, so that the high-level data except the target information can be used by other terminals demodulation.

Or, only when the high-level data other than the target information and the target information are transmitted to the same terminal (target transmission end), the terminal multiplexes the high-level data except the target information to transmit the target information on the PSSCH so that higher layer data other than the target information can be demodulated.

In the embodiment of the present application, when the target information carries request information, or the target information is used to trigger resource selection for request signaling, the method further includes:

The terminal selects the first transmission resource corresponding to the target information, and the setting of the first resource reservation period (resource reservation interval) corresponding to the resource selection of the first transmission resource includes at least one of the following:

Or, the resourcereservation interval may also be independently determined by the MAC layer of the terminal, so as to improve the flexibility of resource usage.

Optionally, in the case that the coordination information can be multiplexed with high-layer data other than the coordination information and transmitted on the same PSSCH, the first resource reservation period is set by the MAC layer of the terminal.

Optionally, when the terminal determines that there is periodic TB transmission, the terminal may periodically send request signaling, such as sending a MAC CE carrying request information, or sending a second-stage SCI carrying request information, and so on.

In this embodiment of the present application, assuming that the terminal is a first terminal, and the first resource reservation period is indicated by the first-stage SCI associated with the first transmission resource corresponding to request signaling, the method may further include :
