Abstract
In a communication station, such as a UE or Node B of a 3GPP system, where channelization coded signals are received on physical channels of at least one coded composite transport channel (CCTrCh) within timeslots of a system time frame, the actual number of channelization codes transmitted for the CCTrCh within a system time frame is determined. The transmitted channelization codes are then identified by performing a channelization code identification algorithm based on the determined number.
Claims18
A method for a 3GPP communication system wherein channelization coded signals are received on physical channels of at least one coded composite transport channel (CCTrCh) within timeslots of a system time frame comprising determining the actual number of channelization codes transmitted for the CCTrCh within a system time frame and identifying the channelization codes by performing a channelization code identification algorithm based on the determined number.
A communication station configured to receive channelization coded signals on physical channels of at least one coded composite transport channel (CCTrCh) within timeslots of a system time frame where each transmitted CCTrCH is comprised of a selected number of Transport Channels (TrCHs), each TrCH having a data streams arranged in a predetermined Transport Format (TF) of a Transport Format Set (TFS) of that TrCH which is in effect for a given Transmission Time Interval (TTI) of timeframes and a Transport Format Indicator (TFI) that identifies the TF of the TrCH's TFS in effect for that TrCH, the TFIs of all the TrCHs of a CCTrCH being combined into a Transport Format Combination Indicator (TFCI) from which the formatting and channelization codes of the transmitted CCTrCH in a given TTI can be determined and where the TFCI is transmitted with the corresponding CCTrCH in at least a first timeslot of each TTI in which the CCTrCH is transmitted, the communication station having a receiver comprising:
- a TFCI processing component having a first section configured to process received TFCIs to produce a value representing the number of transmitted channelization codes of a corresponding CCTrCH and a second section configured to process received TFCIs using the values produced by the first section to identify a list of the transmitted channelization codes for each corresponding CCTrCH.
