摘要： An apparatus and method for efficiently operating a fast feedback channel in a wireless communication system are provided. A method for operating a feedback channel in a Base Station (BS) of a wireless communication system includes identifying feedback information types of one or more feedback channels intended to be deallocated among a plurality of existing allocated feedback channels for a Mobile Station (MS), activating a bit corresponding to the identified feedback information type in a ‘deallocation bitmap’ field within a DownLink (DL) control signal, and transmitting the DL control signal to the MS. Among the feedback information types of the plurality of existing allocated feedback channels, the feedback information type having the smallest value corresponds to the highest priority bit among bits within the ‘deallocation bitmap’ field.

摘要： Methods for maintaining continuing existence of a next-in-line protecting device in a beacon network including a primary protecting device (PPD), the next-in-line protecting device (NPD) and a plurality of secondary protecting devices (SPDs). In one method, a subset of the plurality of secondary protecting devices periodically transmit beacon messages to the primary protecting device. When the next-in-line protecting device disappears, the primary protecting device selects a secondary protecting device from among the secondary protecting devices that have transmitted the beacon messages within a certain period to be a new next-in-line protecting device. In another method, the plurality of secondary protecting devices continuously monitor an existence of the next-in-line protecting device. When the next-in-line protecting device disappears for a certain period of time, a subset of the plurality of secondary protecting devices may contend to be a new next-in-line protecting device. In still another method, the primary protecting device transmits a beacon message to the plurality of secondary protecting devices to indicate whether a next-in-line protecting device is required. When a next-in-line protecting device is required, a subset of the secondary protecting devices contend to be a new next-in-line protecting device.
