Abstract
An etiquette controller (112) in a transmitter (14) in a first radio frequency (RF) communications system (10) enables radio frequency communications in a frequency bandwidth shared with heterogeneous RF communication systems (15). The etiquette controller (112) monitors the first RF signals in an isochronous frequency channel in a sub-band of the shared frequency bandwidth to determine whether (124) a frequency channel is free or whether (130, 136) the frequency channel comprises a communication channel which is free. In addition, the etiquette controller (112) causes the RF transceiver (102) to transmit (148) a channel relinquishment signal, monitors (150) the isochronous frequency channel for a predetermined monitoring time, and determines (152) whether the isochronous frequency channel is then free for the channel access.
