Abstract:
1. An apparatus for scheduling resource allocation to control inter-cell interference in a cellular communication system, the apparatus comprising: a bitmap generator for receiving scheduling information from evolved Node-Bs of a plurality of neighbor cells, and for generating scheduling information including its cell's bitmap information for the resource allocation using the received neighbor cells' scheduling information; and a scheduler for scheduling the resource allocation for User Equipments (UEs) in its cell based on the scheduling information provided from the bitmap generator and power allocation information of the UEs in its cell, wherein the bitmap generator determines a neighbor cell set for generation of the bitmap information by selecting a predefined number of neighbor cells from among the plurality of neighbor cells, wherein the bitmap generator receives Reference Signal Received Power (RSRP) information for the plurality of neighbor cells from the UEs in its cell to generate the bitmap information, wherein the predefined number of neighbor cells is selected according to the RSRP information in descending order of the RSRP, and wherein the bitmap information comprises its cell's Relative Narrowband Transmit Power (RNTP) bitmap information.
