    • The present invention relates to a method for balancing the distribution of interference between radio cells in a wireless communication system comprising cells in which subcarrier blocks are used for communication. A number of adjacent cells build a cell cluster. Moreover, the present invention relates to a corresponding method adapted for use in a system in which multi beam antennas or multiple antennas are used. Furthermore, the present invention relates to base stations performing the above method as well as a communication system comprising the base stations. 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 cell of a cell cluster, to determine transmission power ranges for each of the cells of said cell cluster, and to assign transmission power ranges to the subcarrier block sets to perform TPC within the ranges.
    • 本发明涉及一种用于平衡无线通信系统中的无线电小区之间的干扰分布的方法,所述无线通信系统包括其中子载波块用于通信的小区。 许多相邻的单元格构建单元格集群。 此外,本发明涉及适用于其中使用多波束天线或多个天线的系统中的相应方法。 此外,本发明涉及执行上述方法的基站以及包括基站的通信系统。 为了减少大的平均SIR变化而不引起额外的SIR估计,如功率控制引入的测量和计算问题,本发明建议将子载波块分组成小区簇的每个小区中的多个子载波块集合,以确定发射功率范围 并且将发送功率范围分配给子载波块集合以在该范围内执行TPC。
