ABSTRACT:
A wireless communication system includes base stations with adaptive antenna arrays that communicate with remote communication devices. The base stations monitor the power of uplink signals received from user terminals, and generate a downlink array pattern that directs signals toward desired users and directs nulls toward undesired users. A base station will increase the strength of the downlink signals directed to a desired user from which it senses an increasing uplink signal power and will deepen the null directed to an undesired user from which it senses an increasing uplink signal power. The remote devices monitor the quality of downlink signals they receive and increase the power of the uplink signal they transmit in order to improve received downlink signal quality.
