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.
