A selective call radio (SCR) ( 100 ) is provided for exchanging messages with a base station ( 150 ) on inbound and outbound channels. The SCR has a wireless transceiver ( 102 ), and a processor ( 104 ). The processor is programmed to determine ( 204 ) a priority setting for the SCR, and upon detecting an appropriate priority setting, transmit ( 210 or 214 ) a resource request message to the base station on a select one of one or more unused transmission slots ( 162 ) near in time to a transmission on the outbound channel of control information by the base station.
