User equipment scheduling method in cellular uplink communication system and base station apparatus therefor

摘要

A method and an apparatus maximize the capacity of a wireless communication network by taking into consideration inter-cell interference coordination. A home cell's capacity sensitivity to interference is calculated. At least one neighbor cell's capacity sensitivity to interference is collected. And at least one UE located in the home cell is scheduled based on the home cell's capacity sensitivity and the neighbor cell's capacity sensitivity. Accordingly, it is possible to achieve power and allocation control to maximize the capacity of the overall network including neighbor cells increase the system capacity in a cellular system in which inter-cell interference is large, and adaptively perform a UE scheduling in real time to changing distribution of UEs because information on a change in the capacity of each cell is shared by periods.
