Claim:
1. A method of reducing uplink control channel overhead at a user equipment (UE), the method comprising: determining that a total transmit power of the UE exceeds an allocated power; scaling a transmit power of a high-speed dedicated physical control channel (HS-DPCCH) relative to a transmit power of a dedicated physical control channel (DPCCH) to reduce the ratio of the HS-DPCCH power relative to the DPCCH power such that the HS-DPCCH is transmitted with a reduced transmit power in response to the determination that the total transmit power of the UE exceeds the allocated power; and transmitting an indication that the total transmit power of the UE exceeds the allocated power, wherein the indication is signaled through a transport format combination index (TFCI) field of the DPCCH.
