Abstract:
1. A transmission power control method of a forward-acknowledgement channel, comprising: receiving packet transmission control information in a base station, the received packet transmission control information including a boost identifier to identify a boost operation; and determining a power of a transmission signal to be transmitted from the base station via the forward-acknowledgement channel (F-ACKCH) using an increment for a reference transmission power value of a boost mode when the packet transmission control information contains the boost identifier to identify the boost operation, wherein the increment for the reference transmission power value is determined based on a sub-packet identification (SPID) or a service data unit length (SDU length) transmitted via a reverse-packet data control channel, and wherein the power of the transmission signal to be transmitted via the forward-acknowledgement channel (F-ACKCH) is determined by adding the increment to the reference transmission power value of the boost mode when the signal is an acknowledgement (ACK) signal.
