POWER ADAPTIVE METHOD AND APPARATUS IN A HETEROGENEOUS NETWORK

摘要

A method and apparatus in a heterogeneous network includes: receiving, by a pico base station, reference signal received power of a serving base station and a neighboring base station reported by multiple pieces of user equipment (UE) within its coverage; calculating, by the pico base station, an average value of data received power of the UE and an average value of the reference signal received power of the UE for receiving reference signal transmitted by the macro base station according to the reference signal received power; and transmitting the above calculation result by the pico base station to the macro base station, so that the macro base station determines transmitted power of a unicast physical channel in an almost blank subframe configured by the macro base station for the pico base station; the throughput of the system is optimized accordingly.

1. A pico base station, comprising:
a receiving unit configured to receive measurement values reported by multiple pieces of UE within a coverage of the pico base station, the measurement values including reference signal received power of each piece of the UE for receiving reference signal transmitted by the pico base station and reference signal received power of each piece of the UE for receiving reference signal transmitted by a macro base station, wherein the macro base station configures the pico base station with an almost blank subframe; a calculating unit configured to calculate an average value of data received power of the UE according to the reference signal received power of each piece of the UE for receiving reference signal transmitted by the pico base station, and calculate an average value of the reference signal received power of the UE for receiving reference signal transmitted by the macro base station according to the reference signal received power of each piece of the UE for receiving reference signal transmitted by the macro base station; and a transmitting unit configured to transmit the average value of the data received power of the UE and the average value of the reference signal received power of the UE for receiving reference signal transmitted by the macro base station to the macro base station.
