Signaling uplink control information in lte-a

A method for transmitting uplink control information, the method comprising:

• a wireless transmit/receive unit (WTRU) determining that uplink control information is to be transmitted in a time interval and that the uplink control information comprises a first subset of uplink control information bits and a second subset of uplink control information bits, wherein the first subset of uplink control information bits comprise at least a first type of uplink control information and the second subset of uplink control information bits comprise at least a second type of uplink control information;
• determining that the WTRU is to perform simultaneous transmissions on a first channel and a second channel during at least the time interval, wherein one of the first channel or the second channel is capable of transmitting data information;
• and
• transmitting, during the time interval, the first subset of uplink control information bits on the first channel and transmitting, during the time interval, the second subset of uplink control information bits on the second channel.

A wireless transmit/receive unit (WTRU) comprising:

• a process configured to at least:
• determine that uplink control information is to be transmitted in a time interval and that the uplink control information comprises a first subset of uplink control information bits and a second subset of uplink control information bits, wherein the first subset of uplink control information bits comprise at least a first type of uplink control information and the second subset of uplink control information bits comprise at least a second type of uplink control information;
• determine that the WTRU is to perform simultaneous transmissions on a first channel and a second channel during at least the time interval, wherein one of the first channel or the second channel is capable of transmitting data information;
• and
• a transmitter configured at least to transmit, during the time interval, the first subset of uplink control information bits on the first channel and transmitting, during the time interval, the second subset of uplink control information bits on the second channel.
