Transmission power level setting during channel assignment for interference balancing in a cellular wireless communication system

摘要

The present invention relates to a method for balancing the distribution of interference between radio cells in a wireless communication system comprising cells: each of them comprising at least two sectors in which subcarrier blocks are used for communication. A sector of a radio cell and its adjacent sectors in neighboring radio cells build a sector cluster. Furthermore, the present invention relates to a base station performing the above method. To reduce the large average SIR variations without causing additional SIR estimation, measurement and calculation problem as introduced with power control the invention suggests to group subcarrier blocks into a plurality of subcarrier block sets in each of the sectors of each radio cell of the sector cluster, to determine transmission power levels for each of the sector of the sector cluster, and to assign transmission power levels to the subcarrier block sets.
