Carry out in the data transmission system of scheduling controlling in employing base station, the dispatching distribution of all resources of system is undertaken by base station usually, such as, the resource situation etc. that can use when resource allocation conditions when downlink transfer is carried out in base station and terminal carry out uplink, these are all distributed by base station scheduling.

At OFDM (Orthogonal Frequency Division Multiplexing, referred to as OFDM) in system, in same sector, when base station and different terminals carry out downlink data transmission, because these down links are orthogonal, therefore can avoid disturbing in sector.But the down link between different sector may not be orthogonal, therefore each terminal may be subject to the descending interference of the base station from other adjacent sectors, i.e. inter-sector interference.

If inter-sector interference is serious, then power system capacity can be reduced, the covering power of the particularly transmittability of sector-edge user, and then influential system and the performance of terminal.In order to overcome inter-sector interference and ensure certain bandwidth availability ratio, the interference coordination technique of time-frequency domain can be adopted, different sub band resources is distributed to edge termination, to reduce inter-sector interference intensity.

Lower for same base station 3 adjacent sectors are numbered 1 according to the difference in its antenna main lobe direction, 2,3 by step 1: be first numbered sector respectively; Can sort according to certain rule for the running time-frequency resource of terminal scheduling, assuming that all running time-frequency resources can be divided into N3 part according to minimum schedulable running time-frequency resource particle, then number consecutively is 1,2 ... N1, N1+1 ... N2, N2+1 ... N3-1, N3.Then this resource is divided into 3 parts, is designated as F1, F2, F3, give 3 sectors respectively, specific as follows:

For the sector being numbered 1, the set F1 that running time-frequency resource particle 1,2...N1 forms is considered as its low interference region, and this region original position index is 1, and final position index is N1, and remaining region is then high interference region;
