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.
