POWER ADAPTATION METHOD AND DEVICE IN HETEROGENEOUS NETWORK
摘要
<p>Embodiments of the present invention provide a power adaptation method and device in a heterogeneous network. The method comprises: a micro base station receiving reference signal received power of a serving base station and a neighboring base station reported by multiple user equipments (UEs) covered by the micro base station; the micro base station calculating, according to the reference signal received power, an average value of data received power of the UEs and an average value of reference signal received power of reference signals received by the UEs and sent by a macro base station; the micro base station sending a calculation result to the macro base station, so that the macro base station determines accordingly transmit power of a unicast physical channel in an almost empty subframe configured by the macro base station for the micro base station. The method and device of the embodiments of the present invention optimize the system throughput, and reduce interference incurred by downlink transmission of the macro base station to the UE of the micro base station.</p>
