Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for uplink transmission using multiple antennas.

SOLUTION: A wireless transmit/receive unit (WTRU) performs space time transmit diversity (STTD) encoding on an input stream of a physical channel configured for STTD. Each physical channel is mapped to either an in-phase (I) branch or a quadrature-phase (Q) branch. The WTRU performs the STTD encoding either in a binary domain or in a complex domain. Additionally the WTRU performs pre-coding on at least one physical channel including an E-DPDCH (dedicated physical data channel) and transmitting pre-coded output streams via a plurality of antennas.
