    • PROBLEM TO BE SOLVED: To provide a method for controlling the output of an access packet (PA) transmitted from a mobile station (MS) so that input variations of a receiver of a transmitting-receiving base station can be reduced.
      SOLUTION: Within a base transmitting-receiving station (BTS), output information indicating the transmission power (TPo(BTS)) of a broadcast channel (BCCH) is included on the broadcast channel. Within a mobile station (MS), the output received on this channel is measured; this measured output value (RP(MS)) is compared with the transmission output power obtained from transmission output power information contained in the broadcast channel (BCCH), to derive the estimate of the propagation loss from the mobile station (MS) to the base transmitting-receiving station (BTS); and optimal transmission power for the access packet (PA) is determined, using the estimated propagation loss and parameters of a system. The method can be used for radiotelephony, particularly, a GSM system and a TETRA system.

    • 要解决的问题:提供一种用于控制从移动台(MS)发送的接入分组(PA)的输出的方法,从而可以减少发射接收基站的接收机的输入变化。 解决方案:在基站发射接收站(BTS)内,在广播信道上包括指示广播信道(BCCH)的发射功率(TPo(BTS))的输出信息。 在移动台(MS)内测量在该信道上接收的输出; 将该测量输出值(RP(MS))与从广播信道(BCCH)中包含的发送输出功率信息获得的发送输出功率进行比较,以导出从移动台(MS)到基站的传播损耗的估计 发射接收站(BTS); 并且使用估计的传播损耗和系统的参数来确定用于接入分组(PA)的最优发射功率。 该方法可用于无线电话,特别是GSM系统和TETRA系统。 版权所有(C)2010,JPO&INPIT
