Title
(EN) Inter-cell power control in presence of fractional frequency reuse
(ZH) 在存在部分频率重用时的小区间功率控制
Abstract
(EN)
System(s) and method(s) are provided for inter-cell power control in the presence of fractional frequency reuse in a wireless communication system. Transmission power control of a terminal, and ensuing inter-cell interference mitigation, is accomplished by receiving load indicators from non-serving sectors, decoding those load indicators corresponding to the non-serving sectors that operate in the same frequency bands as the terminal, and adjusting the transmission power according the states of the decoded load indicators in conjunction with the associated non-serving sectors forward link signal-to-interference-and-noise ratio at the terminal. The states of the load indicators reflect magnitudes of interference metrics with respect to threshold values. Load indicators can also be conveyed by the non-serving sector to a base station serving the terminal through a backhaul communication, and said base station can schedule an adjusted transmission power for the terminal.

提供了用于在无线通信系统中在部分频率重用下进行小区间功率控制的系统和方法。通过从非服务扇区(230i)接收负载指示符(246i),对与非服务扇区对应的负载指示符进行解码,其中所述非服务扇区在与所述终端相同的频带下操作,以及根据所述解码后的负载指示符的状态以及相关联的非服务扇区前向链路信号与干扰及噪声比来调整所述终端处的发送功率,从而实现对终端(210)进行发送功率控制,并确保小区间干扰得以减缓。所述负载指示符的状态表明干扰度量的大小与阈值之间的关系。负载指示符还可以由非服务扇区通过回程(250)通信传送至为该终端提供服务的基站(260),且所述基站可以为该终端调度调整后的发送功率。
