Abstract:
1. A method for performing uplink (UL) transmit diversity implemented in a wireless transmit/receive unit (WTRU), comprising: transmitting a pilot bit on a plurality of transmit antennas; receiving a signal including UL preceding information via a physical channel having slots, wherein each slot of the physical channel includes a plurality of bits and a subset of the bits is assigned to the WTRU for carrying the UL preceding information for the WTRU wherein the UL preceding information includes UL preceding weights; applying the UL preceding weights to an UL transmission; and transmitting the UL transmission; wherein multiple dedicated physical control channels (DPCCHs) are simultaneously transmitted over a plurality of antennas, wherein the multiple DPCCHs are transmitted using different scrambling codes and/or different channelization codes, or multiple DPCCHs carrying different pilot bit sequences are transmitted.
