Patent
CA 2447291
A wideband code division multiple access (W-CDMA) user equipment (UE) operating in frequency division duplex mode for receiving data over at least one of a plurality of high speed (HS) shared control channels (SCCHs) is disclosed. The UE includes means for monitoring the plurality of HS-SCCHs; means for receiving a packet over at least one of the plurality of HS-SCCHs; and means for determining whether a UE identification is present in the packet and whether a circular redundancy code (CRC) of the packet is correct by processing a mask field. The mask field has an N-bit CRC modulo 2 combined with an N-bit UE identification.
A method for data related downlink signaling including selectively tailoring the UE ID to create a UE ID value, which is then added to a data field to create a data mask. This data mask is then further processed as the CRC field and transmitted with the data burst to provide CRC-related functions. An alternative embodiment discloses initializing a CRC generator with UE identification prior to CRC generation. This implicity includes the UE ID within the CRC without requiring additional overhead signaling.
