Patent ID: 8705456

Claim:
A wireless transmit/receive unit (WTRU) comprising: a processor and a transmitter configured to transmit control information on a physical uplink channel; wherein in response to a receiver receiving a transmission for the WTRU in a downlink shared channel in a first transmission time interval (TTI), the processor and the transmitter are configured to transmit on the physical uplink channel in a second TTI to indicate an acknowledgement or a negative acknowledgement; wherein the processor and the transmitter are configured to transmit channel quality information periodically in TTIs, as periodic TTIs, on the physical uplink channel, wherein the channel quality information includes a delta channel quality information value; wherein in response to the second TTI overlapping with one of the periodic TTIs, as an overlapping TTI, the processor and transmitter are configured to selectively include or drop an indication of the channel quality information in the overlapping TTI on the physical uplink channel based on predefined rules established by a higher layer; wherein in response to the second TTI not overlapping with one of the periodic TTIs of the channel quality information, the processor and the transmitter transmit an indication of the acknowledgement or negative acknowledgement and not an indication of the channel quality information on the physical uplink channel; and wherein the physical uplink channel is not a random access channel.
