1. A method for sending feedback for a multicast/broadcast transmission comprising:
- decoding multicast/broadcast data received from a transmitter on a downlink resource;
forming a feedback message based on quality of reception of the multicast/broadcast data if selected as a feedback reporting user terminal based on a statistical sample independent of the feedback message of a fraction of user terminals from among a class of user terminals receiving the multicast/broadcast data;
queuing the feedback message for transmission to the transmitter on an uplink resource that corresponds to the downlink resource;
wherein for unicast transmissions the uplink resource is dedicated to an uplink transmission corresponding to a downlink transmission on the downlink resource;
wherein the feedback message is part of a statistically sampled feedback scheme, wherein a subset of the total number of receivers in communication with the transmitter is sampled; and
wherein the sampled receivers belong to more than one category and the statistically sampled feedback scheme is based in part on the more than one category.

Abstract
Feedback from user stations to the base station for a multicast/broadcast transmission is performed by decoding multicast/broadcast data received from a transmitter on a downlink resource, forming a feedback message corresponding to the reception of the multicast/broadcast data, and queuing the feedback message for transmission to the transmitter on an uplink resource. The uplink resource used corresponds to the downlink resource used for the multicast/broadcast transmission. For unicast transmissions the uplink resource is dedicated to an uplink transmission corresponding to a downlink transmission on the downlink resource.
