Non-Cooperative Power Control For Large-Scale Antenna Systems

摘要

A base station servicing a cell of a cellular network provides power control of a cell independent of any other cell in the network. For downlink power control, the base station transmits information at its full power and applies a downlink power control factor to each downlink channel to equalize downlink throughputs of the mobile terminals in the cell. For uplink power control, the base station transmits instructions to have the uplink channel with the worst channel condition to transmit at its full power and the other uplink channels to transmit at that same full power. Each transmission is scaled by a corresponding uplink power control factor such that uplink throughputs for the mobile terminals in the cell are equalized. The base station applies an approximation of a rigorous capacity lower bound algorithm using propagation channel conditions and channel parameters to calculate the uplink and downlink power control factors.

1. A method comprising:
transmitting, by a base station servicing a cell of a cellular communication network, information over one or more downlink channels of the cell where the base station transmits the information at full power scaled by a downlink power control factor for each of the downlink channels with each of the downlink power control factors being calculated by the base station using propagation channel conditions and channel parameters of each corresponding downlink channel and where the transmission is performed by the base station independent of any other cell of the cellular communication network.
