As shown in fig. 2, an embodiment of the present application provides a resource selection method, including:

step 201: the first terminal sends a first request signal, wherein the first request signal is used for requesting to acquire resource selection information of target transmission.

The resource selection method is suitable for an enhancement scheme of a resource allocation mode in a related protocol, in the enhancement scheme, the UE-B sends request signaling to the UE-A, the UE-A feeds coordination signaling back to the UE-B after request signaling is received, and the UE-B performs resource selection for TB transmission based on coordination signaling.

In this step, the first request signal may be specifically one request signaling, and the target transmission may be specifically a transmission performed for one resource selection. Such as at least one TB transmission. The resource selection information may include at least one of: the second terminal trends to the resource information used by the first terminal; the second terminal does not prefer the resource information used by the first terminal.

Step 202: the first terminal acquires a first collaboration signal associated with the first request signal, wherein the first collaboration signal carries resource selection information of the target transmission.

In this embodiment of the present application, the first terminal may receive a plurality of first collaboration signals (coordination signaling), where the first collaboration signals associated with the first request signal may be acquired in an implicit manner (such as a protocol reservation) or in an explicit manner (such as indicated by indication information), so that resource selection can be performed for the target transmission based on resource selection information carried by the first collaboration signals.

Step 203: and the first terminal performs resource selection according to the resource selection information of the target transmission indicated by the first collaboration signal.

In the embodiment of the present application, a first terminal sends a first request signal, acquires a first collaboration signal associated with the first request signal, and performs resource selection based on resource selection information of a target transmission indicated by the first collaboration signal.

Optionally, the first terminal acquires a first collaboration signal associated with the first request signal, including:

the first terminal acquires a first collaboration signal associated with the first request signal according to target information carried by at least one collaboration signal;

wherein the target information is used for indicating at least one of the following:

request the transmission resource information of the signal;

requesting control information associated with the signal;

and (5) target identification.

In a specific embodiment of the present application, the above transmission resource information includes at least one of a time domain resource and a frequency domain resource, and the target information, when indicating the transmission resource information of the request signal, may indicate index information of the time domain resource and/or the frequency domain resource, for example, a slot index (slot index) indicating the request signal, or a start (Physical Resource Block, PRB) index indicating the request signal.

The control information includes transmission parameters or HARQ related parameters (e.g., HARQ process ID, etc.).

The target identification may be at least one of a request ID (request ID), a collaboration ID (coordination ID), and a logical channel identification (Logical channel ID), for example, the target identification is Logical channel ID.

The above target information may be specifically indicated by 2 nd-stageSCI.

Optionally, the first terminal obtains a first collaboration signal associated with the first request signal according to target information carried by at least one collaboration signal, including:

determining first target information associated with the first request signal in target information carried by the at least one cooperative signal, wherein the target information comprises at least one of the transmission resource information and the control information;

and taking the collaboration signal carrying the first target information as a first collaboration signal associated with the first request signal.

In a specific embodiment of the present application, the target information is used to indicate transmission resource information of a request signal and/or control information associated with the request signal, and then the first terminal obtains, according to the target information, first target information associated with a first request signal, that is, transmission resource information indicated by the first target information is transmission resource information of the first request signal, or control information indicated by the first target information is control information associated with the first request signal, and takes a collaboration signal carrying the first target information as the first collaboration signal. The manner is to explicitly indicate a first collaboration signal associated with the first request signal.

and taking the collaboration signal carrying the same target identification as the first request signal as the first collaboration signal.

Here, the target information is used to indicate a target identifier carried by the collaboration signal, and the manner in which the target information indicates the target identifier indicates the first collaboration signal associated with the first request signal is an explicit manner.

taking the received collaboration signal in the target time period as a first collaboration signal associated with the first request signal;

wherein the target time period refers to a time period between a first time and a second time;

the first time is the sending time of the first request signal, the second time is a T1 < + > preset time interval, and T1 is associated with the sending time of the first request signal.

For example, T1 is a time when the first request signal is first transmitted, or is a time when the first request signal is nth 1 transmitted, or is a time when the first request signal is last transmitted, or is a time when a physical sidelink feedback channel (Physical SideLink Feedback Channel, PSFCH) associated with the physical sidelink shared channel (Physical SideLink Shared Channel, PSSCH) is transmitted for the request signal; the above-mentioned preset time interval is predetermined for the protocol or is (pre) configured or indicated for the first terminal. The predetermined time interval may be determined based on a packet delay budget (Packet Delay Budget, PDB). The predetermined time interval may be a delay budget (Packet Delay Budget, PDB) used when selecting the first cooperative signal transmission resource for the second terminal, which receives the first request signal and feeds back the first cooperative signal to the first terminal accordingly.

In the embodiment of the present application, the second time is set to ensure that the collaboration signal received by the first terminal in the target time period is used as the first collaboration signal. In this manner, only one cooperative signal is received within the target period. The manner is a manner of implicitly indicating the first collaboration signal.

Optionally, after the first terminal sends the first request signal, the method further includes:

the first terminal transmits a second request signal, wherein the transmission time of the second request signal is after the second time, or the transmission time of the second request signal is after the reception time of the first collaboration signal.

The first request signal may specifically be a transmitted next request signal after the first terminal transmits the first request signal.

In this embodiment of the present application, when the first terminal receives the previous cooperative signal or the transmission of the previous cooperative signal exceeds the preset data packet delay budget (Packet Delay Budget, PDB), the first terminal can only send the new request signal, so that the request signal and the cooperative signal always have a one-to-one correspondence relationship. The manner is also a manner of implicitly determining the first collaboration signal. The typical value of the delay budget is equivalent to the delay budget used by the second terminal when selecting the first cooperative signal transmission resource.

and taking the collaboration signal corresponding to the target first resource number as a first collaboration signal associated with the first request signal.

For example, when the first terminal receives a plurality of cooperative signals, the cooperative signal having a smaller resource number (time domain resource number or frequency domain resource number) is associated with the request signal having a smaller resource number (time domain resource number or frequency domain resource number). This approach also belongs to the approach of implicitly determining the first collaboration signal.

taking the collaboration signal meeting the preset condition as a first collaboration signal associated with the first request signal;

wherein the preset conditions include at least one of:

the receiving time delay is smaller than or equal to the preset receiving time delay, and if the cooperative signal received in the preset receiving time delay is the first cooperative signal;

The selection resource corresponding to the carried resource selection information meets the requirement indicated by the first terminal (the first request signal), for example, the sub-channel size (sub-channel size) meets the requirement indicated by the first request signal, and the time domain position meets the requirement indicated by the first request signal;

transmitting in the same resource pool or carrier as the first request signal;

the same resource pool or carrier is validated as the first request signal.

The above manner of using the collaboration signal satisfying the preset condition as the first collaboration signal associated with the first request signal belongs to a manner of implicitly determining the first collaboration signal.

Optionally, in an embodiment of the present application, the request signal and/or the collaboration signal carries at least one of the following:

resource pool information;

carrier information.

step 301: the second terminal receives request signals sent by at least one first terminal, wherein each request signal is used for requesting to acquire resource selection information of one target transmission.

Step 302: the second terminal sends at least one cooperative signal according to the at least one request signal, wherein the cooperative signal carries target information and resource selection information of target transmission, and the target information is used for indicating the association relationship between the cooperative signal and the request signal.

In the embodiment of the present invention, the second terminal sends a collaboration signal according to at least one request signal, where the collaboration signal carries target information for indicating an association relationship between the collaboration signal and the request signal and resource selection information of the target transmission, so that the first terminal can select a first collaboration signal associated with a first request signal sent by the first terminal through the target information, and perform resource selection based on the resource selection information carried by the first collaboration signal, thereby ensuring that the first terminal can accurately select a suitable resource for the target transmission.
