Patent ID: 8737506

Claim:
A method of operating a wireless access system, the method comprising: exchanging wireless communications with a plurality of user devices that presently use a first transmit diversity time delay, the wireless communications being transmitted at a first instance in time and a second instance in time separated according to the first transmit diversity time delay; receiving multipath information from the user devices based on the wireless communications received by the user devices from the wireless access system, wherein the multipath information comprises radio frequency (RF) power information determined by each of the user devices for the wireless communications received under multipath wireless conditions; processing the multipath information received from the user devices to determine a second transmit diversity time delay for use in the user devices to reduce RF transmit power by the wireless access system while still maintaining a threshold level of RF signal quality experienced by the ones of the user devices; transferring an indicator of the second transmit diversity time delay to the user devices; and exchanging further wireless communications with the user devices using the second transmit diversity time delay in the user devices, the further wireless communications being transmitted at a third instance in time and a fourth instance in time separated according to the second transmit diversity time delay.
