    • PURPOSE: A method for power control and an apparatus thereof for minimizing the downlink signaling overhead in a wireless communications system are provided to reduce the overhead of the downlink control channel for a TPC(Transmit Power Control) command according to a closed loop power control. CONSTITUTION: A controller(511) assigns an uplink control channel to one or more terminals. The controller receives control information through the uplink control channel. An SINR(Signal-to-Interference-plus-Noise-Ratio) calculation unit(513) measures SINR of the uplink control channel. A TPC electrical transmission positioning unit(515) transmits the TPC command in consideration of the SINR at a predetermined interval.
    • 目的:提供一种用于功率控制的方法及其装置,用于使无线通信系统中的下行链路信令开销最小化,以根据闭环功率控制来减少TPC(发射功率控制)命令的下行链路控制信道的开销。 构成:控制器(511)向一个或多个终端分配上行链路控制信道。 控制器通过上行链路控制信道接收控制信息。 SINR(信号与干扰加噪声比)计算单元(513)测量上行链路控制信道的SINR。 TPC电传输定位单元(515)以预定间隔发送考虑到SINR的TPC命令。

    • PURPOSE: A cooperation transmission method using a code book designed by multi cells in a wireless communication network and the wireless communication system therefor are provided to generate a multi cell code book in a plurality of base stations to perform cooperation communication through the multi cell code book in the base stations, thereby increasing performance of a multi cell MIMO(Multi Input Multi Output) system. CONSTITUTION: A serving base station receives a PMI(Precoding Matrix Indication or Precoding Matrix Index) and average receiving power from a terminal(S301). The serving base station transmits the received PMI and the average receiving power to a cooperation base station(S303). The serving base station and the cooperation base station generate a multi cell code book using a shared single cell code book(S305). The serving base station and the cooperation base station are cooperated with a terminal by applying a precoding matrix that the received PMI indicates(S307).
    • 目的:提供一种使用由无线通信网络中的多小区设计的码本及其无线通信系统的协作传输方法,用于在多个基站中生成多小区码本,以通过多小区码本执行协作通信 在基站中,从而增加多小区MIMO(多输入多输出)系统的性能。 构成:服务基站从终端接收PMI(预编码矩阵指示或预编码矩阵索引)和平均接收功率(S301)。 服务基站向合作基站发送接收的PMI和平均接收功率(S303)。 服务基站和协作基站使用共享单小区码书生成多小区码本(S305)。 通过应用接收的PMI指示的预编码矩阵,服务基站和协作基站与终端协作(S307)。
