Providing CCTrCH data with a header containing configuration parameters for use in processing the CCTrCH data

摘要

Disclosed is a method of processing CCTrCH data using a CCTrCH processing stack comprising at least two stages. Each CCTrCH data block is provided with a header containing configuration data. At each processing stage of the stack the header is read along with the input data in order to gain the configuration data which that processing stage requires. The header is attached to the output data of each processing stage. Extra configuration data may be attached to the header at this point, for use in a subsequent stage. This method avoids disadvantages of using a central controller and allows processing to proceed from one processing step to another without requiring prior knowledge of the processing latencies of each processing step.
