Patent ID: 7639644

Claim:
A wireless transmit/receive unit (WTRU) for providing fast detection of a high speed shared control channel (HS-SCCH), the WTRU comprising: a plurality of decoders for receiving downlink control messages including a last received downlink control message transmitted via a plurality of monitored HS-SCCHs and calculating an accumulated soft metric for each of the HS-SCCHs; a threshold comparator which receives the calculated accumulated soft metrics from the decoders and determines that at least two of the accumulated soft metrics pass a threshold test and are close in value; and a selector for selecting a high-speed downlink shared channel (HS-DSCH) indicated by the particular monitored HS-SCCH to receive downlink messages, on a condition that one of the at least two accumulated soft metrics is associated with a particular one of the monitored HS-SCCHs used to receive the last received downlink control message.
