摘要： Aspects of the invention are directed to a transmit diversity method for use in a wireless terminal having a plurality of antennas and a wireless terminal configured to implement the method. The transmit diversity method includes using a different orthogonal sequence for each antenna, or group of antennas, for transmitting an uplink control channel from a wireless terminal to a base station. A first step of the method involves assigning at least one orthogonal sequence to one or more of the plurality of antennas, each of the plurality of antennas being assigned at least one orthogonal sequence. Once the orthogonal sequence is assigned, a further step involves scrambling a signal to be transmitted on the physical uplink control channel (PUCCH) using the at least one orthogonal sequence for each antenna thereby producing a scrambled PUCCH for transmission by each antenna. The scrambled PUCCH can then be transmitted on the plurality of antennas.
