In order to better understand the technical solutions of the embodiments of the present application, the following technical contents are firstly introduced:

NR sidelink resource allocation/selection

There are two ways to allocate NR SL resources, one is based on base station scheduling (mode 1), and the other is based on UE autonomous resource selection (mode 2). 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 transmitting terminal (Transmit 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) After the resource selection is triggered, the TX UE first determines the resource selection window, the lower boundary of the resource selection window is T1 time after the resource selection is triggered, and the upper boundary of the resource selection is after the trigger The T2 time, where T2 is the value selected by the UE in the packet delay budget (Packet Delay Budget, PDB) of its transport block (Transport Block, TB) transmission, and T2 is not earlier than T1. 2) UE in resources Before the selection, it is necessary to determine the candidate resource set (candidate resource set) for resource selection, and compare the Reference Signal Received Power (RSRP) measured on the resources in the resource selection window with the corresponding RSRP threshold, if If the RSRP is higher than the RSRP threshold, 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 (3dB), and then the resource exclusion operation is performed , 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 allocation/selection enhancements

The enhancement scheme of resource allocation method is divided into scheme 1 and scheme 2.

For scheme 1, UE-A decides a resource set, UE-A sends 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. The resource set indicated by the Coordination signaling can be "the transmission resources that UE-A prefers to be used by UE-B (that is, preferred resource set)", or "the transmission resources that UE-A does not prefer to use by UE-B (that is, non-preferred resource set)")". The transmission of the coordination signaling may be triggered by a request signal (request signaling) sent by UE-B, or by a preset condition.

For scheme 2, the Physical Sidelink Feedback Channel (Physical Sidelink Feedback Channel, PSFCH) is used as coordination signaling to indicate the resource conflict of UE-B. The transmission of PSFCH is triggered by a preset condition (that is, resource conflict of UE-B).

The determination method of non-preferred resource in Inter-UE coordination scheme 1:

For scheme 1, UE-A can recommend a non-preferred resource set to UE-B, and the way UE-A determines the non-preferred resource includes one or more of the following:

Type 1: non-preferred resource obtained based on condition 1-B-1 option 1: UE-A determines the non-preferred resource based on resources reserved by other UEs, and the RSRP measurement value associated with the reserved resource is greater than the preset threshold, In order to protect the reliability of sending information from UE-B to UE-A.

Type 2: non-preferred resource obtained based on condition 1-B-1 option 2: UE-A determines the non-preferred resource based on resources reserved by other UEs, and the RSRP measurement value associated with the reserved resource is less than the preset threshold. The reserved resource may be a receiving resource of UE-A, and UE-A sends a non-preferred resource to protect the receiving performance of UE-A on the reserved resource.

Type 3: non-preferred resource obtained based on condition 1-B-2: UE-A determines the non-preferred resource based on the SL receiving resources it does not expect, in order to protect the reliability of information sent from UE-B to UE-A, Unexpected SL receiving resources may include one or more of the following:

(1) SL transmission resource (or time resource) of UE-A.

(2) When UE-B sends a Physical SideLink Shared Channel (PSSCH) to UE-A, the resources (or time resources) that cause UE-A's PSFCH to send and receive conflicts, that is, half-duplex conflicts.

(3) When UE-B sends PSSCH to UE-A, the resource (or time resource) that causes UE-A's PSSCH transmission and reception conflict, that is, half-duplex conflict.

(4) When UE-B sends PSSCH to UE-A, resources (or time resources) that cause conflict between UE-A's PSSCH reception and UL transmission.

(5) When UE-B sends PSSCH to UE-A, resources (or time resources) that cause UE-A's PSFCH transmission and UL transmission conflict, that is, co-transmission conflict.

Transmission type of coordination signaling transmission in Inter-UE coordination scheme 1 (cast type)

Based on the coordination signaling transmission generated by the request, the cast type of the coordination signaling transmission is unicast.

Based on the coordination signaling transmission generated by the condition, the cast type can be one or more of groupcast, broadcast, and unicast.

According to the above introduction, considering that there are many possibilities for the cast type of coordination signaling transmission, the target UEs of coordination signaling of different cast types are different, so it is necessary to solve how UE-A transmits different types of coordination information to the corresponding UE-B, so that UE -B can effectively receive and utilize relevant coordination information.

The method for determining the transmission resource provided by the embodiment of the present application is introduced below with reference to the accompanying drawings:

Referring to Fig. 1 , the embodiment of the present application provides a method for determining transmission resources. The execution body of the method is the first terminal, specifically UE-B as in the above introduction, and correspondingly the opposite end of SL communication with the first terminal It is the second terminal, specifically UE-A as described above, and the method includes:

Step 101: The first terminal receives one or more coordination signaling sent by the second terminal, where the coordination signaling carries the first information indicated by the second terminal for the first terminal; the coordination signaling carried The information can also be called auxiliary information; it should be noted that, as described above, since the second terminal may send coordination signaling in various ways (unicast, multicast, broadcast), the first terminal may receive the first One or more coordination signaling sent by the two terminals.

Step 102: In the case where the first information indicates the first resource, the first terminal determines the resource type and/or resource selection behavior of the transmission resource according to the transmission type of the coordination signaling; and/or, in the first information In the case of indicating the first resource, the first terminal determines the resource type of the first resource according to the first indication information;

It should be noted that the first condition above may specifically refer to condition 1-B-1 option 1; the second condition above may specifically refer to condition 1-B-1 option 2; the third condition above may specifically refer to condition 1-B-1 B-2. For specific condition 1-B-1 option 1; condition 1-B-1 option 2; condition 1-B-2, please refer to the corresponding introduction and description above, and will not repeat them here.

In a possible implementation manner, there is a mapping relationship between the above-mentioned transmission type of coordination signaling and resource type and/or resource selection behavior.

In the embodiment of the present application, the corresponding relationship between the transmission type of coordination signaling (coordination signaling cast type) and the resource type (resource type) of the transmission resource is established, so that the coordination signaling cast type and the resource type have an association relationship, so that the first terminal can pass The cast type judges the resource type in order to determine in which scenario the resource is used. In this way, based on the mapping relationship between the transmission type of coordination signaling and the resource type and/or resource selection behavior of the transmission resource, the first terminal determines the resource type and/or resource selection of the transmission resource according to the coordination signaling sent by the second terminal Behavior to ensure accurate and effective transmission of coordination information.

It should be noted that the coordination signaling sent by the second terminal will carry indication information to indicate which transmission type the coordination signaling is, so when the first terminal receives the coordination signaling sent by the second terminal, it can know The transport type for this coordination signaling.

That is, the protocol stipulates, configures and/or pre-configures the signaling forms of different types of non-preferred resources, so as to distinguish different types of non-preferred resources.

For example: when the resource type of the first resource is the first type or the second type, the coordination signaling is 1st stage SCI; that is, the non-preferred resource of Type 1 or Type 2 is indicated by the 1st stage SCI;

When the resource type of the first resource is the third type, the coordination signaling is MAC CE or 2nd stage SCI. That is, the non-preferred resource of Type 3 is carried by MAC CE or 2nd stage SCI.

(2.2) If the first terminal can identify the non-preferred resource based on condition option 1-B-1 option 1 or condition 1-B-2 contained in the coordination signaling, when the first terminal sends groupcast TB to the UE group, The transmission resource selection of the TB considers the non-preferred resource obtained based on condition option 1-B-1 option 1 or condition 1-B-2.

(3.2) If the first terminal can identify the non-preferred resource contained in the coordination signaling based on condition option 1-B-1 option 1 or condition 1-B-2, when the first terminal sends a broadcast TB, the TB's The transmission resource selection considers the non-preferred resource obtained based on condition option 1-B-1 option 1 or condition 1-B-2.

(3.3) If the first terminal can identify that the coordination signaling contains or only contains the non-preferred resource obtained based on condition option 1-B-1 option 2, when the first terminal sends any TB, the transmission resource selection of the TB takes this into account The non-preferred resource obtained based on condition option 1-B-1 option 2.

In a possible implementation manner, before the first terminal receives the coordination signaling sent by the second terminal, the method further includes: the first terminal sends a request signaling to the second terminal, and the request signaling is used to request the coordination signaling, that is, the corresponding The scene where the first terminal triggers coordination signaling through a request.

Wherein, the request signaling or coordination signaling carries the first indication information for indicating the resource type of the transmission resource.

In a possible implementation, the resource type indication field, the preferred resource and non-preferred resource identification indication fields, and one or more joint codes in the request signaling and coordination signaling indication indication fields. That is, resource type indication, preferred resource/non-preferred resource indication, and/or request/coordination signaling indication can be jointly coded to save signaling overhead.

For example: only the resource type can be indicated in the indicator field, and the preferred resource/non-preferred resource is implicitly determined based on the resource type;

For example: a code point in the indication field indicates whether the signaling is request signaling, and other code points are used to indicate what type of resource type the signaling carries as a coordination signaling;

Considering the same UE-B, in a period of time, it may receive multiple coordination signaling, and the information carried by different coordination signaling may be different. Therefore, it is necessary to solve how UE-B can effectively distinguish different coordination signaling, so as not to confuse different coordination signaling. coordination information.

In a possible implementation manner, multiple coordination signaling is transmitted according to a preset timing, including:

Among the plurality of coordination signalings, the first coordination signaling triggered by the request signaling sent by the first terminal is sent within the preset delay limit (latency bound), and the second coordination signaling other than the first coordination signaling among the plurality of coordination signalings Sent after the preset latency bound.

The purpose is to avoid breaking the correspondence between the request and the corresponding coordination signaling.

Optionally, the second coordination signaling is transmitted to the first terminal, or has the same destination address as the first coordination signaling, or has the same transmission type as the first coordination signaling.

Considering that when UE-A and UE-B receive/send coordination signaling, they will receive/send other signals at the same time, so it is necessary to solve how to ensure that the interaction between coordination signaling and other signals is small, and how to protect coordination signaling/ The validity and reliability of other more important signal transmissions.
