The method for performing uplink transmission diversity in a switched antenna OFDM communication system the wireless communication device and the customer is provided. The switching of the antennas used by the customer radio communication apparatus to transmit the uplink signal, the channel quality associated uplink and the shifted transmission of the signal immediately before the gap, the transition occurs in the gap has subsequently, but the channel quality-related transmission of the uplink signal There is limited to the switching period comprises one or more of the preceding period, the channel quality associated uplink signal, by the serving radio access network, be used to update the channel response and the antenna array weights associated with the customer wireless communication device can. Then, the client wireless communication device, only during the switching period, and switching the antenna used for uplink transmission.
