Abstract:
1. A method for providing uplink transmit diversity in a switched antenna Orthogonal Frequency Division Multiplexing communication system, the method comprising: restricting the switching of antennas for use by a customer's wireless communication device to transmit an uplink signal to switching time periods comprising one or more of a transition gap immediately preceding a transmission of a channel quality-related uplink signal and a time period subsequent to an occurrence of the transition gap but prior to the transmission of the channel quality-related uplink signal, which transmission 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; and switching, by the customer's wireless communication device, from use of a first antenna of a plurality of antennas to use of a second antenna of the plurality of antennas for uplink transmissions only during the switching time periods.
