Method and apparatus for implementing uplink transmit diversity in a switched antenna orthogonal frequency division multiplexing communication system

摘要

A method and a customer's wireless communication device are provided that perform uplink transmit diversity in a switched antenna OFDM communication system. A switching of antennas used by the customer's wireless communication device to transmit an uplink signal is restricted to switching time periods that comprise one or more of a transition gap immediately preceding a transmission of a channel quality-related uplink signal and a time period subsequent to the occurrence of the transition gap but prior to the transmission of the channel quality-related uplink signal, which channel quality-related uplink signal may be used by a serving radio access network to update a channel response and antenna array weights associated with the customer's wireless communication device. The customer's wireless communication device then switches antennas used for uplink transmissions only during the switching time periods.
