Abstract
A method and arrangement for processing of CCTrCH data in a UMTS system, by: receiving CCTrCH data across a plurality of radio frames and timeslots (310); storing the received CCTrCH data (320); and upon receipt of complete data for a CCTrCH, processing the stored CCTrCH data through channel processing asynchronously to the received timeslot structure (360). Preferably, the received CCTrCH data is stored in a single RAM memory in link-list form, whereby each timeslot of received CCTrCH data can be independently accessed in the memory. This method of buffering the different parts of the received CCTrCH data, so that they can be recombined before the TrCH decoding and de-multiplexing, is both memory efficient and spreads out the processing load over time.
