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.
