Patent ID: 7010317

Claim:
A UE apparatus for determining transmission power of a second TFCI (Transmit Format Combination Indictor) bit indicating transport format information of data on a downlink shared channel transmitted from a selected Node B to a UE (User Equipment) in a mobile communication system including the UE existing in a handover zone and a plurality of Node Bs in an active set indicating Node Bs capable of communicating with the UE, wherein the Node Bs transmit dedicated channel data including a first TFCI bit to the UE over dedicated channels, wherein the selected Node B among the Node Bs transmits dedicated channel data including the first TFCI bit and the second TFCI bit over a dedicated channel and transmits downlink shared channel data over the downlink shared channel, wherein a dedicated channel frame from the selected Node B has a plurality of time slots, each of the time slots including a transmission data field and a TFCI field indicating transport format information of the transmission data, each of the TFCI fields including a first field where the first TFCI bit indicating transport format information of the dedicated channel data transmitted over the dedicated channels is located and a second field where the second TFCI bit indicating transport format information of the downlink shared channel data transmitted over the dedicated shared channel is located, the apparatus comprising: a plurality of common channel pilot estimators for estimating levels of common channel pilot signals received from the Node Bs in the active set; and a downlink transmission power control command generator for determining a transmission power offset of the second TFCI bit using the measured levels of the common channel pilot signals, provided from the common channel pilot estimators.
