Abstract: A wireless transmit/receive unit (WTRU) includes a receiver configured to receive first information from a wireless network, the first information indicating a first pattern of time intervals in which the WTRU is to monitor a plurality of control channels. The WTRU further includes a baseband processor operatively coupled to the receiver, the baseband processor and the receiver configured to not monitor the plurality of control channels in time intervals outside the first pattern of time intervals. The receiver is configured to receive a downlink shared channel transmission from the wireless network. The baseband processor is operatively coupled to a transmitter, and the baseband processor and the transmitter are configured to transmit an indication of an outcome of a decoding attempt of the downlink shared channel transmission a fixed number of timeslots after transmission of the downlink shared channel transmission. The indication may be transmitted on an uplink control channel.

Abstract: A wireless transmit/receive unit (WTRU) includes circuitry configured to receive first information from a wireless network, the first information indicating a first pattern of time intervals in which the WTRU is to monitor a plurality of control channels; not monitor the plurality of control channels in time intervals outside the first pattern of time intervals; and receive second information from the wireless network, the second information indicating a second pattern of time intervals in which the WTRU is to transmit control information on a control channel.

Abstract: A wireless transmit/receive unit includes a receiver and a processor. The receiver is configured to receive a plurality of high-speed shared control channels (HS-SCCHs), wherein the plurality of HS-SCCHs are received over a plurality of discrete time intervals. The processor is configured to instruct the receiver to receive all of the plurality of HS-SCCHs during one of the plurality of discrete time intervals.

Abstract: A method for maximizing battery efficiency of a wireless transmit/receive unit (WTRU) is disclosed. In one embodiment, a predetermined number of high-speed shared control channels (HS-SCCHs) are identified and WTRUs are instructed to monitor the HS-SCCHs according to a predetermined schedule. The predetermined schedule can include monitoring the HS-SCCHs in the same timeslot, either a timeslot just for the HS-SCCHs or a timeslot utilized by another channel.
