Abstract

The invention provides a resource exclusion method and apparatus. The method comprises the following steps: if a first network node monitors that at least one second network node occupies resources within a service period allowed by the system and smaller than L on a receiving sub-frame in a first listening window corresponding to a first target moment, judging whether the second network node satisfies a first preset condition, wherein the first preset condition is that any one of the subsequent M1 times of reservation resources of the second network node is within a first resource selection window corresponding to the first target moment, and M1 is a positive integer; when the second network node satisfies the first preset condition, performing resource exclusion according to M2 times ofreservation resources starting from the starting point position of the first resource selection window of each second network node, wherein M 2 is a positive integer, and M2 is less than or equal to aproduct of L dividing the service period of the second network node; and performing resource selection according to a resource exclusion result. The resource conflict opportunity is reduced, and theutilization rate of resources is improved.

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...
