Abstract
System and method for decoding punctured subframes. A preferred embodiment comprises a first deinterleaver unit (for example, 5-ms deinterleaver) and a second deinterleaver unit (for example, 20-ms deinterleaver) operating in parallel, deinterleaving one symbol stream using 5- and 20-ms duration frame formats, for example. After the reception of each 5-ms subframe, the subframe is decoded in a decode unit (for example, rate matching, decoding, and CRC checking (RDC) unit) to verify that the subframe contains 5 ms duration frame data. If so, the subframe is noted. If all 5-ms subframes in a 20-ms duration frame contain 5-ms duration data, no decoding of results by the second deinterleaver unit is needed. If the entire 20-ms duration frame is not all 5-ms duration data, then the 5-ms duration data subframes are zeroed and the remaining data is decoded as 20-ms duration data.
