Abstract
To efficiently coordinate the transmission of information from a plurality of radios to a base station on the forward channel of an RF channel, transmission time on the forward channel is scheduled by the base. To be allowed to transmit information on the forward channel, a radio first sends a request frame to the base to request permission to access the forward channel. After sending the request frame, the radio waits for the base to assign it a reserved information time slot. Only if an information time slot is reserved, and only during that reserved time slot, may the radio send an information frame on the forward channel. In determining whether to reserve an information time slot for the radio, the base station takes into consideration the priority of the radio. This allows the base station to better coordinate signal activity on the forward channel. Since transmission time on the forward channel is scheduled, conflicting transmissions are minimized. Thus, forward channel capacity is used more efficiently.
