Method and system for implicit user equipment identification

Abstract
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.
