Abstract
A method and apparatus for sending uplink control information (UCI) by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation are disclosed. The multi-mode WTRU may generate first UCI pertaining to a first RAT and second UCI pertaining to a second RAT. The WTRU may then send at least part of the first UCI and least part of the second UCI via a feedback channel on a component carrier of a second RAT. The first RAT may be Long Term Evolution (LTE) and the second RAT may be LTE-Advanced (LTE-A) or vice versa. Each RAT may operate on a different frequency. The UCI of the RATs may be multiplexed onto a carrier of any one of the RATs. The UCI bits for a pair of or multiple serving cells may be jointly encoded.

Claim
1. A method for sending uplink control information (UCI) by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation, the method comprising:
generating first UCI pertaining to a first RAT, wherein the first RAT is one of Long Term Evolution (LTE) and LTE-Advanced (LTE-A), and second UCI pertaining to a second RAT, wherein the second RAT is one of LTE and LTE-A, wherein the first UCI includes a first channel quality indicator (CQI) and the second UCI includes a second CQI;
multiplexing at least part of the first UCI pertaining to the first RAT and at least part of the second UCI pertaining to the second RAT onto a physical layer channel on a component carrier of the second RAT; and
sending the physical layer channel, wherein a particular UCI is prioritized over another UCI in accordance with a priority rule.
2. The method of claim 1 wherein, the first UCI further includes at least one of hybrid automatic repeat request acknowledgement (HARQ-ACK), a precoding matrix indicator (PMI), a rank indication (RI), a pre-coding control indication (PCI), a scheduling request (SR), an Enhanced Dedicated Channel (E-DCH) transport format combination indicator (E-TFCI), a happy bit, and a retransmission sequence number (RSN); and
wherein, the second UCI further includes at least one of HARQ-ACK, a PMI, an RI, a PCI, an SR, an E-TFCI, a happy bit, and an RSN.
3. The method of claim 1 wherein, the first RAT is LTE operating on a first frequency and the second RAT is LTE-A operating on a second frequency.
