Abstract:
1. A system for use in wirelessly transmitting a communication signal to a remote transceiver, said system comprising: an array of transmit antenna elements arranged in a predetermined pattern; a direction determination unit to determine a direction of the remote transceiver; a transmit beamformer coupled to said array of antenna elements to generate a transmit beam in the direction of the remote transceiver; a power control unit to determine an antenna gain related parameter associated with said transmit beam generated by said transmit beamformer and to adjust a transmit power level of said system based on said antenna gain related parameter; and a duty cycle unit, coupled to said power control unit, to determine an average transmit duty cycle of said system over a predetermined time period and to deliver said average transmit duty cycle information to said power control unit, wherein said power control unit uses said average transmit duty cycle information to adjust the transmit power level of said system.
