Abstract

The present invention provides a resource exclusion method and device. The method includes: if the first network node monitors at least one second network node on the receiving subframe within the first monitoring window corresponding to the first target time The service cycle of L occupies resources, and it is judged whether the second network node satisfies a first preset condition; wherein, the first preset condition is that any one of the subsequent M1 resources reserved by the second network node reserves resources falls within the first resource selection window corresponding to the first target moment; M1 is a positive integer; when the second network node satisfies the first preset condition, according to each second network node from the first resource Select M2 reservation resources starting from the starting point of the window for resource exclusion; M2 is a positive integer, and M2 is less than or equal to L divided by the service cycle of the second network node; then select resources according to the resource exclusion results to reduce the chance of resource conflicts and improve resource utilization.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a resource exclusion method and device. Background technique [0002] In the prior art, when selecting resources, the network node UE monitors resources reserved by other terminals to effectively avoid resources that may conflict. Such as figure 1 As shown, the network node 1 (UE1) now needs to select resources in its own resource selection window, and it needs to process its own sending subframe and other subframes in the sensing window it monitors. [0003] 3GPP's existing processing methods: [0004] Assume that UE1 needs to select resources according to the period P1 and reserve N times; [0005] For other subframes k that are not sent by UE1 itself, UE1 can monitor k. Assume that UE1 monitors that UE2 occupies time-frequency resource D with period P2. When 100<=P2<=1000, if subframe k+P2 and x , x+P1, ..., any subframe in x+(N-1)*P1 overlaps, then UE...
