The time unit may be the length of the resource selection window, for example, the length of 32 time slots, and the third time period may be p resource selection windows, or 1/p of the resource selection window, where p is greater than 0 rational numbers.

Or, in another possible implementation manner, the first communication device may not perform resource selection or resource scheduling or resource recommendation for the second communication device in units of time periods, and may implement resource selection or resource scheduling or resource recommendation in units of time intervals (ie, cycles) or by terminals. The (ie, aperiodic) determination time is for the second communication device to perform resource selection, resource scheduling, or resource recommendation. At this time, the first communication device can maintain a queue to be processed, and the sorting method of the queue is determined according to the first target value of each second communication device. For example, the higher the first target value (priority), the higher the position in the queue. forward. Each time the first communication device receives a piece of first information, it determines the position of the second communication device in the queue to be processed according to the first target value of the second communication device corresponding to the first information, and is performing resource selection and resource scheduling. Or when recommending resources, according to the order in the queue to be processed, respectively perform resource selection, resource scheduling or resource recommendation for the second communication device in the to-be-processed queue, and send the second information.

In the above possible implementation manner, when multiple pieces of the first information are received at the same time, the multiple pieces of first information are determined according to the first target values of the second communication devices corresponding to the multiple pieces of first information. The order between the two communication devices in the pending queue.

In the above possible implementation manner, in order to avoid frequent changes of positions of the second communication device in the queue to be processed, according to the first target value, it is determined that the priority of the second communication device corresponding to the currently received first information is greater than or equal to The first proportion of the second communication devices in the to-be-processed queue reorders the second communication devices in the to-be-processed queue according to the first target value, or reorders the currently received first information The corresponding second communication device is placed in the P-th position of the queue to be processed, where P is less than Q, and Q is the total number of senders in the queue to be recommended. If the priority of the second communication device corresponding to the currently received first information is smaller than the first proportion of the second communication devices in the queue to be processed, the second communication device corresponding to the currently received first information is placed in the The tail of the pending queue.

In a possible implementation manner, after S214, the method may further include: sending the second information to the at least one second communication device, wherein the second information carries the information determined for the second communication device or the second information carries resource information determined for the second communication device that is not conducive to transmission; or the second information carries resource information determined for the second communication device that is conducive to transmission; Or the second information carries resource information determined for the second communication device that is not available for data transmission. Through the second information, the second communication device may determine resource information used for data transmission.

In the above possible implementation manner, the second information further carries the identifier of the target receiving end of the service that the second communication device needs to transmit. The identifier can be the UE ID of the target receiver, or the group ID where the target receiver is located, that is, the group ID, or the group ID of the group where the target receiver is located, that is, the M_ID. For example, in Fig. 4, TX UE 1 requests Co-UE for resources for communication and transmission with RX UE 2, Co-UE can determine the first target value of RX UE 2, and can send second information to RX UE 2, so The second information may carry the identity of the RX UE 2. Through this possible implementation manner, the second communication device can determine the data transmission resource with the target receiving end.

In a possible implementation manner, before the first communication device sends the second information to the second communication device, if at least one of the following conditions (1) to (3) is satisfied, the first communication device is discarded. Sending or transmitting the second information, or abandoning resource selection or resource scheduling or resource recommendation for the second communication device.

(1) The transmission time of the second information exceeds the delay requirement of the service to be transmitted of the second communication device.

(2) The transmission time of the second information exceeds the latest transmission time of the service to be transmitted of the second communication device.

(3) The transmission time of the second information exceeds the latest transmission time of the second information.

The transmission time of the second information may be the earliest transmission time of the second information or the latest transmission time of the second information. For example, the transmission time of the second information may be the time when the second information is sent from the first communication device, or may be the time when the second information arrives at the second communication device. Specifically, it may be determined according to the delay requirement of the service to be transmitted, the latest transmission time of the service to be transmitted, and the latest transmission time of the second information.

For example, if the transmission time of the second information is the time when the second information arrives at the second communication device, the first communication device may determine the transmission time of the second information before transmitting the second information, and then according to the transmission time of the second information Relevant information and network environment, estimate the transmission time of the second information from the first communication device to the second communication device, so as to estimate the time for the second information to reach the second communication device, so as to determine whether the time exceeds the delay demand, or the latest transmission time of the service to be transmitted, or the latest transmission time of the second information.

Through this possible implementation, the collision problem that occurs when the recommended resources are selected can be solved, the feasibility of the solution can be further improved, and the transmission performance and system performance can be improved.

In a possible implementation manner, when sending the second information to at least one second communication device, the second information may also be sent according to the first target value, for example, according to the first target value from small to large or from large to large In a minor order, the second information is sent to the second communication device.
