20100322102 | UPLINK FEEDBACK IN A MULTIMEDIA BROADCAST/MULTICAST SERVICES (MBMS) WIRELESS COMMUNICATIONS SYSTEM - A technique for managing uplink feedback involves establishing a channel quality threshold range, for example, in terms of a channel quality indicator (CQI), broadcasting the channel quality threshold range to the mobile stations and using the channel quality threshold range to control the feedback of channel quality information. For example, the mobile stations determine their own mobile station-specific CQI and then generate CQI feedback information in response to a comparison between their own mobile station-specific CQI and the CQI threshold range. In an embodiment, if the CQI of a mobile station falls within the CQI threshold range, then the mobile station can transmit a reduced set of CQI feedback information. For example, the reduced set of CQI feedback information may be a single bit that indicates whether the mobile station-specific CQI is greater than or less than a CQI threshold or whether the CQI has crossed a CQI threshold. | 12-23-2010 |
