Abstract:
1. A method of transmission power control for a wireless transmit receive unit (WTRU) that transmits communication signals in a forward composite channel carrying data in a selected combination of channels with respect to a selected physical transmission configuration of the forward composite channel, the method comprising: transmitting communication signals in the forward composite channel in a selected combination of channels with respect to a first physical transmission configuration of the forward composite channel; determining a reference combination of channels with respect to the first physical transmission configuration of the forward composite channel; applying a gain factor β to the transmission of communication signals in the selected combination of channels with respect to the first physical transmission configuration of the forward composite channel where the gain factor β is determined based on spreading factors of the selected combination of channels and the reference combination of channels with respect to the first physical transmission configuration of the forward composite channel; reconfiguring the transmission of communication signals in the forward composite channel to transmit the signals in a selected combination of channels with respect to a second physical transmission configuration of the forward composite channel; determining a reference combination of channels with respect to the second physical transmission configuration of the forward composite channel; and applying a gain factor β′ to the transmission of communication signals in the selected combination of channels with respect to the second physical transmission configuration of the forward composite channel where the gain factor β′ is determined based on spreading factors of the selected combination of channels and the reference combination of channels with respect to the second physical transmission configuration of the forward composite channel.
