ABSTRACT:
A method and apparatus is provided for a operating a radio communication system (100). The system (100) has a sequence of communication channels (205), including a reservation channel, and a channel hopping protocol for operating on the sequence (205). A hop period is defined for the channel hopping protocol. A transceiver (113) monitors the reservation channel to find an open communication slot (213), having a duration less than the channel hop period, and cyclically channel hops through the sequence of communication channels in the open slot (213). The transceiver (113) reserves the communication slot (213) for a subsequent cycle through the sequence by transmitting a reservation signal on the reservation channel.
