A system and method for optimizing random access control, and for optimizing transmission efficiency of data packets over reverse common channels between access terminals and a base station, in a wireless communications system. In the communications system, at least one of the access terminals is adapted to transmit at least a portion of an access data packet to the base station, and the base station is adapted to receive the portion of the access data packet and, in response, to transmit a message for receipt by the plurality of access terminals which indicates receipt of the access data packet portion by the base station and identifies the access terminal from which said access data packet portion is received. The message can control the other access terminals to refrain from transmitting an access data packet, while indicating receipt of the access data packet portion to the certain access terminal from which the access data packet portion had been transmitted. The base station can also provide power control signals to control transmission power of that certain access terminal, and to control that certain access terminal to transmit over certain reverse channels. Accordingly, interference between access data packets being transmitted by multiple access terminals and being received in the same time slot by a base station in a wireless communications system can also be minimized.
