Abstract  Abstract

The invention claims a method and device for uplink transmission using multiple antennas of. performing STTD encoding on the input stream of the physical channel is a space-time transmit diversity (STTD) configuration of the wireless emitting/receiving unit (WTRU). Each physical channel may be mapped to the in-phase (I) branch or the quadrature-phase (Q) branches. WTRU in binary domain or in the complex domain performing STTD encoding. Additionally the WTRU may perform precoding on the comprises E-DPDCH of the at least one physical channel using the precoding weights and encoded through multiple antennas of the transmitted output stream. pre-coding can be performed after or before the expansion operation.

Method and apparatus for uplink transmission using multiple antennas are disclosed. 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 may be mapped to either an in-phase (I) branch or a quadrature-phase (Q) branch. The WTRU may perform the STTD encoding either in a binary domain or in a complex domain. Additionally the WTRU may perform pre-coding on at least one physical channel including the E-DPDCH with the pre-coding weights and transmitting the pre-coded output streams via a plurality of antennas. The pre-coding may be performed either after or before spreading operation.
