Abstract: An apparatus and method reduce power consumption in a broadband wireless communication system. A transmitting end apparatus that includes a plurality of transmit (Tx) antennas includes a control block, a Processor (DSP) block, a modem block, and at least one power controller. The control block determines a traffic amount based on an amount of used resources. The Digital Signal Processor (DSP) block performs scheduling by using a subset of Tx antennas and a subset of resources on a frequency axis if the traffic amount is less than a threshold. The modem block applies boosting to a signal transmitted using the subset of resources. And at least one controller turns off an operation of at least one power amplifier that corresponds to at least one Tx antenna that is not included in the subset of Tx antennas.

Abstract translation: 一种降低宽带无线通信系统功耗的装置和方法。 包括多个发送（Tx）天线的发送端设备包括控制块，处理器（DSP）块，调制解调器块和至少一个功率控制器。 控制块基于所使用资源的数量来确定流量。 如果业务量小于阈值，则数字信号处理器（DSP）块通过使用Tx天线的子集和频率轴上的资源子集来执行调度。 调制解调器模块使用资源子集传输的信号进行升压。 并且至少一个控制器关闭对应于不包括在Tx天线的子集中的至少一个Tx天线的至少一个功率放大器的操作。
