A communication unit ( 101 ) and corresponding methods are arranged and constructed to detect acknowledgment messages as an Originator or respond with an acknowledgment message as a Target on a time division channel. The communication unit includes a transceiver ( 201 ) configured to support air interfaces ( 113, 115 ) with other communication ( 103, 105 ) units according to frequency hopping patterns and a controller ( 203 ) cooperatively controlling the transceiver to, for example, send a call setup message identifying a target communication unit and a pseudo-random frequency hopping pattern; and to determine whether an acknowledgment message from the target communication unit is present in a signal received according to the pseudo-random frequency hopping pattern.
