    • PROBLEM TO BE SOLVED: To enable selecting a frequency channel for transferring radio packets between base stations by avoiding deterioration in throughput in each of radio cells. SOLUTION: In a radio packet communication system, a plurality of base stations transmit/receive packets to/from subordinate terminal stations by different frequency channels, and packet transfer is performed between the base stations. In the frequency selecting method of the radio packet communication system, frequency channels different from each other are assigned to a plurality of antennas used by the base stations for packet transmission/reception to/from the subordinate terminal stations and packet transfer to another base station, a combination of frequency channels is obtained in which reception power at the time of receiving a measuring signal transmitted from one antenna by the other antenna is not more than a threshold, and the combination is selected as a combination of frequency channels to be assigned to each of antennas.

    • 要解决的问题:为了能够选择用于在基站之间传送无线电分组的频道,以避免每个无线电小区中的吞吐量的恶化。 解决方案:在无线电分组通信系统中,多个基站通过不同的频率信道向/从下属终端发送/接收分组,并且在基站之间执行分组传送。 在无线分组通信系统的频率选择方法中,将彼此不同的频率信道分配给基站使用的多个天线,用于向下属终端站发送/接收分组,并将分组传送到另一个基站, 获得频率信道的组合,其中在接收由另一个天线从一个天线发送的测量信号时的接收功率不大于阈值,并且将该组合选择为分配给每个天线的频率信道的组合 的天线。 版权所有(C)2006,JPO&NCIPI
