Patent ID: 8837348

Claim:
A relay transmission method, comprising: for transmission of a data frame between Access Points, APs, and UEs, determining groups of sets of AP identifiers composed of disjoint sets of AP identifiers among sets of AP identifiers corresponding to the UEs, wherein a set of AP identifiers comprises AP identifiers of APs capable of serving a UE; allocating the same resource to UEs corresponding to sets of AP identifiers in the same group of sets of AP identifiers and different resources to UEs corresponding to sets of AP identifiers in different groups of sets of AP identifiers according to the determined groups of sets of AP identifiers; and instructing the APs in the set of AP identifiers corresponding to the UE to serve the UE by using the resource allocated to the UE, wherein determining the groups of sets of AP identifiers composed of disjoint sets of AP identifiers among the sets of AP identifiers corresponding to the UEs comprises: determining a group of sets of AP identifiers comprising the largest number of disjoint sets of AP identifiers among unselected sets of AP identifiers, and identifying the sets of AP identifiers in the group of sets of AP identifiers as “Selected”; and repeating the foregoing step until all the sets of AP identifiers are identified as “Selected”.
