1. A method implemented in a subscriber unit, wherein a multicast group comprises a plurality of subscriber units, the method comprising:
- receiving a multicast group indication message, from a base station, via a first one of a plurality of wireless channels, the multicast group indication message identifying a connection identifier associated with a multicast message, wherein the connection identifier is associated with an indication of a second one of the plurality of wireless channels over which to receive the multicast message from the base station;
receiving the multicast message via the second one of the plurality of wireless channels;
transmitting a negative acknowledgment; and
receiving a retransmission of the multicast message in response to the transmitted negative acknowledgement.

Abstract
A technique for transmitting messages in a wireless communication network to a multicast group using a single wireless channel. A base station processor having a plurality of wireless channels is in communication with a plurality of subscriber access units in a wireless communication network. Multicast messages received by the base station processor are sent to a plurality of the subscriber access units, denoted as a multicast group, in the wireless communication network via a wireless channel dedicated to transmitting multicast messages.

15. A base station for multicasting messages, the base station comprising:
-
a processor configured to receive a multicast message addressed to a multicast group having two or more subscriber units; a transmitter configured to; transmit a multicast group indication message to a multicast group via a first one of a plurality of wireless channels, the multicast group indication message identifying a connection identifier associated with a multicast message, wherein the connection identifier is associated with an indication of a second one of the plurality of wireless channels over which a corresponding multicast message will be transmitted; and transmit the multicast message, to the multicast group, via the second one of the plurality of wireless channels; and a receiver configured to receive a negative acknowledgment from a subscriber unit associated with the multicast group; wherein the transmitter is further configured to retransmit the multicast message in response to the negative acknowledgement. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 28)
