Abstract: In a network comprising a plurality of macro base stations, a plurality of micro base stations and a plurality of user devices (UEs), a method of establishing a wireless communication network includes: assigning the micro base stations into a plurality of clusters and selecting a micro base station from each of the clusters as a cluster head; receiving, from cluster heads of the clusters by the network device, information about candidate sub-clusters determined by UEs, each of the candidate sub-clusters comprises micro base stations whose signal power received at a UE exceeds a pre-defined threshold; identifying at least two schemes of grouping the micro base stations into non-overlapping sub-clusters based on the candidate sub-clusters; for a scheme of the at least two schemes, making each of the UEs select to access a macro base station or to be associated with one of the non-overlapping sub-clusters of the scheme base on respective measurements of signals received from at least one of a macro base station and a sub-cluster of the non-overlapping sub-clusters of the scheme; suppressing, by a UE, inter-symbol interference by subtracting a tail of a first symbol from a second symbol before recovering the second symbol; suppressing, by the UE, inter-carrier interference by adding a tail estimated of the second symbol to the second symbol before recovering the second symbol; acquiring information about power consumption of each of the macro base stations and power consumption of each of the micro base stations in communications with the UEs which performs inter-symbol interference suppression and inter-carrier interference suppression at the UEs; and making the micro base stations perform joint transmissions in sub-clusters as specified in a scheme selected from the at least two schemes according to the information about power consumption.
