发明名称 METHOD AND APPARATUS FOR PERFORMING REVERSE RATE MATCHING IN A CDMA SYSTEM.
摘要 <p>Techniques for processing symbols received for a (transport) channel in a (W-CDMA) communication system. According to the W-CDMA standard, the coded bits of a transport channel are first rate-matched, then first de-interleaved, and then segmented to form X radio frames, where X is the transmission time interval (TTI) of the transport channel. The radio frames can be processed in various manners. In one aspect, the rate-matching and first interleaving can be applied to the coded bits of the transport channel X times to generate a radio frame with each application. In accordance with a method, the correspondence between the coded bit xm and the rate-matched bits yn, and between the rate-matched bits yn and the interleaved bits zk, can be computed based on direct or iterative computations. In another aspects, the first de-interleaving and inverse rate-matching can be applied onto each rad it is received, without having to wait for the remaining radio frames in the TTI to be received. The correspondences between the received symbols zk', de-interleaved symbols yn' and de-rate-matched symbols xm' can be computed. Reduced buffering requirement and reduced processing delays may be achieved based on the above.</p>
