Acknowledgment for a time division channel
First Claim
1. A communication unit arranged and constructed to detect acknowledgment messages on a time division channel, the communication unit comprising:
- a transceiver configured to support air interfaces with other communication units according to frequency hopping patterns;
a controller coupled to and cooperatively controlling the transceiver to;
send a call setup message identifying at least one target communication unit, the call setup message further indicating a pseudo-random frequency hopping pattern; and
determine whether an acknowledgment message from the at least one target communication unit is present in a signal received according to the pseudo-random frequency hopping pattern.

Abstract
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.

10. A method of setting up a call between an originating communication unit and one or more target communication units, the method comprising:
-
first exchanging a call setup message between the originating communication unit and the one or more target communication units, the call setup message identifying at least one target communication unit and specifying a frequency hopping pattern that is pseudo-random; and
second exchanging, responsive to the call setup message, an acknowledgment message between the at least one target communication unit and the originating communication unit, the acknowledgment message from the at least one target communication unit included in a signal that is transmitted according to the frequency hopping pattern. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A communication unit arranged and constructed to provide acknowledgment messages on a time division channel, the communication unit comprising:
-
a transceiver configured to support air interfaces with other communication units according to frequency hopping patterns;
a controller coupled to and cooperatively controlling the transceiver to;
receive a call setup message;
determine whether the call setup message identifies the communication unit and determine a pseudo-random frequency hopping pattern specified by the call setup message; and
only when the call setup message identifies the communication unit send an acknowledgment message responsive to the call setup message, the acknowledgment message included in a signal that is transmitted according to the pseudo-random frequency hopping pattern. - View Dependent Claims (20)
