摘要： A subscriber unit for automatic repeat request mechanisms and related methods are disclosed. The subscriber unit may comprise transmitting a single carrier frequency domain equalization (SC-FDE) signals using a plurality of hybrid automatic repeat request (ARQ) mechanisms. The plurality of hybrid ARQ mechanisms may use a stop and wait architecture. Further, each of the plurality of hybrid ARQ mechanisms may transmit in a different time interval and each time interval includes at least one time slot. The subscriber unit may receive downlink data signals using hybrid ARQ and may receive acknowledgments (ACKs)/negative acknowledgments, wherein the ACK/NAKs may be received in a time period between the downlink transmissions.

摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node and a receiving node. When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.
