A wireless communication system ( 100 ) and method for providing high speed uplink packet access from user equipment ( 128, 130 ) to a base station ( 114, 116, 118, 120 ). Each of the user equipment ( 128, 130 ) and the base station ( 114, 116, 118, 120 ) includes a transmitter ( 1106, 1206 ), a receiver ( 1104, 1204 ), and a controller ( 1108, 1208 ) coupled to the transmitter and the receiver. Data packets are transmitted from the user equipment ( 128, 130 ) to the base station ( 114, 116, 118, 120 ). Control information, corresponding to the data packets, is transmitted from the base station ( 114, 116, 118, 120 ) to the user equipment ( 128, 130 ). The control information includes an absolute grant channel indicator and/or channelization code(s) assigned to the user equipment ( 128, 130 ). The controller ( 1108 ) of the user equipment ( 128, 130 ) is configured to minimize a number of channelization code per scheduling active set cell to be monitored by the user equipment based on the absolute grant channel indicator and/or to utilize the channelization code(s) in response to handoff and/or entering an active channel state.
