Step S401. Obtain a first information set, where the first information set includes first information received within a first time period.

It should be understood that, optionally, the time period T ₀ may be configured first, and the duration of the first time period may be a period of T ₀ or N times T ₀ ; the duration of the first time period may also be directly configured. The first time period may also be configured to be infinite. All the first information received within the first time period is recorded into the first information set.

Step S402, according to the characteristic information of each first information, determine a second information set from the first information set, and perform resource selection according to the first information in the second information set;

Wherein, the first information set includes the second information set.

In an implementation manner, the second information set is the first information set, that is, all the first information received within the first time period is used for resource selection.

The manner of determining from the first information set that part of the first information is included in the second information set may include at least one of the following:

In an implementation manner, the part of the first information is determined according to the time _t1 when the first communication device receives the first information. Specific examples are as follows:

The first information of the time _t1 in the second time period L is included into the second information set. The second time period is within the first time period.

The M pieces of first information received first in the first information set may be included in the second information set according to the time t ₁ when the first information is received.

In another implementation manner, part of the first information is determined according to whether a connection is established between the first communication device and the second communication device, and the connection may be an RRC connection or a NAS connection. For example, unicast transmission based on an RRC connection, or multicast transmission based on establishing an RRC connection may be performed between the first communication device and the second communication device.

In another implementation manner, the part of the first information is determined according to the quantity of the _first information sent by the second communication device within the second time period T1. For example, if the number of first information sent by the same second communication device received within the second time period T1 exceeds _a third threshold, the corresponding first information is included in the second information set. The length of the second time period T ₁ may be N time periods T ₀ or another defined length.

In another implementation manner, part of the first information is determined according to the User ID of the second communication device. For example, when the first communication device receives the first information sent by the second communication device whose User ID is the target User ID, it includes the first information into the second information set. For example, the second communication device of the target User ID can send and receive unicast or broadcast data, or the second communication device of the target User ID is a scheduling node or a relay node or a network side device or a header user or a scheduling user.

For example, the time of receiving the first information is segmented to obtain L ₁ , L ₂ , L ₃ , etc., and corresponding priorities are respectively determined. The corresponding priorities of the first information received within the same time period are the same.

In another implementation manner, the priority is determined according to the quantity of the first information sent by the second communication device within the fourth time period T3 and/or the quantity _of resources indicated in the first information. For example, the greater the quantity of received first information, the higher the priority; or, the greater the quantity of resources indicated in the received first information, the higher the priority.

In another implementation manner, the priority is determined according to the distance between the first communication device and the second communication device. Specifically, the distance can be determined according to the calculation of RSRP or Zone ID. The farther the distance, the lower the priority.

In another embodiment, the priority is determined according to device properties of the second communication device. For example, when the second communication device is a scheduling UE or node, its corresponding priority is higher.
