Abstract:
1. A method of operating an access terminal that is configured to participate in a multicast session, comprising: receiving a first traffic channel assignment message from an access network including an identifier for the multicast session and not including an assignment of a unicast traffic channel; operating, in response to the first traffic channel assignment message, in a non-feedback mode that is characterized by the access terminal participating in the multicast session without sending channel quality feedback, related to the multicast session, to the access network; receiving a second traffic channel assignment message from the access network during the multicast session that assigns the unicast traffic channel; and transitioning, in response to the second traffic channel assignment message, from the non-feedback mode to a feedback mode that is characterized by the access terminal continuing to participate in the multicast session while sending channel quality feedback, related to the multicast session, to the access network.
