Abstract  Abstract

A technique for transmission power control for a plurality of antenna transmissions of an uplink is disclosed. A wireless transmit / receive unit (WTRU) generates at least one input stream for transmission and applies a gain factor to each channel. The gain factor is determined based on the reference channel power estimate. The WTRU generates and applies a weight to at least two data streams from an input stream for transmission over a plurality of antennas. The gain factor and / or weight is controlled such that the transmit power on each antenna is within the maximum allowed value. The WTRU may perform power scaling on condition that the transmit power on any antenna exceeds the maximum allowed value. The WTRU may scale down the E-DCH dedicated physical data channel (E-DPDCH) before the other channel. For multiple E-DCH streams, the WTRU may calculate the E-DPDCH power offset based on an additional power offset factor due to multiple stream transmissions.
