Claim
1. A method for sending uplink control information 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, by the WTRU, uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI includes a first plurality of hybrid automatic repeat request acknowledgements (HARQ-ACKs) pertaining to a plurality of downlink (DL) transmissions of the first RAT and a second plurality of HARQ-ACKs pertaining to a plurality of DL transmissions of the second RAT; multiplexing, by the WTRU, at least part of the UCI pertaining to the first RAT and at least part of the UCI pertaining to the second RAT onto a physical layer channel on a component carrier of the second RAT; and sending, by the WTRU, the physical layer channel via the second RAT to a base station.
2. The method of claim 1, wherein a particular UCI is prioritized over another in accordance with a priority rule.
3. The method of claim 1, wherein the second RAT is one of Long Term Evolution (LTE) or LTE-Advanced (LTE-A), and the physical layer channel is at least one of a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).
4. The method of claim 1, wherein the first RAT operates on a first frequency and the second RAT operates on a second frequency.
5. The method of claim 4, wherein the second frequency is a lower frequency than the first frequency.
6. The method of claim 1, wherein the first UCI further includes at least one of a channel quality indicator (CQI), 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 a CQI, a PMI, an RI, a PCI, an SR, an E-TFCI, a happy bit, and an RSN.
