Abstract
A method and apparatus 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 are disclosed. The WTRU may generate uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI may include 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. The WTRU may multiplex at least part of the generated UCI pertaining to the first RAT and at least part of the generated UCI pertaining to the second RAT onto a physical channel on a component carrier of the second RAT.

Claim
1. A multi-mode wireless transmit receive unit (WTRU) comprising:
a transceiver coupled to a processor, the transceiver and processor configured to send transmissions using a primary radio access technology (RAT) and a second RAT; and the processor configured to prioritize the transmissions of the primary RAT and the secondary RAT,
wherein transmissions of the primary RAT are prioritized over transmissions of the secondary RAT, and
wherein for transmissions of the secondary RAT, secondary RAT transmissions of a physical uplink control channel hybrid automatic repeat request (HARQ) acknowledgements (ACKs)/negative acknowledgements (NACKs) and scheduling requests are prioritized over secondary RAT transmission of a physical uplink control channel with channel state information (CSI).
2. The multi-mode WTRU of claim 1, wherein the primary RAT has a primary cell group and the secondary RAT has a secondary cell group.
3. The multi-mode WTRU of claim 1, wherein the primary RAT is LTE.
4. The multi-mode WTRU of claim 1, wherein for the secondary RAT, physical uplink shared channel transmissions of HARQ ACKs/NACKs and SRs are prioritized over physical uplink shared channel transmissions of CSI.
5. The multi-mode WTRU of claim 1, wherein the prioritization is related to transmission power.
6. The multi-mode WTRU of claim 1, wherein the transmissions are sent to a base station.
7. The multi-mode WTRU of claim 1, wherein the CSI includes a channel quality indicator.
8. The multi-mode WTRU of claim 1, wherein the transceiver operates using multiple-input multiple output.
9. A method performed by a multi-mode wireless transmit receive unit (WTRU), the method comprising:
sending transmissions using a primary radio access technology (RAT) and a second RAT; and prioritizing the transmissions of the primary RAT and the secondary RAT,
wherein transmissions of the primary RAT are prioritized over transmissions of the secondary RAT, and
wherein for transmissions of the secondary RAT, secondary RAT transmissions of a physical uplink control channel hybrid automatic repeat request (HARQ) acknowledgements (ACKs)/negative acknowledgements (NACKs) and scheduling requests are prioritized over secondary RAT transmission of a physical uplink control channel with channel state information (CSI).
10. The method of claim 9, wherein the primary RAT has a primary cell group and the secondary RAT has a secondary cell group.
11. The method of claim 9, wherein the primary RAT is LTE.
12. The method of claim 9, wherein for the secondary RAT, physical uplink shared channel transmissions of HARQ ACKs/NACKs and SRs are prioritized over physical uplink shared channel transmissions of CSI.
13. The method of claim 9, wherein the prioritization is related to transmission power.
14. The method of claim 9, wherein the transmissions are sent to a base station.
15. The method of claim 9, wherein the CSI includes a channel quality indicator.
16. The method of claim 9, wherein the multi-mode WTRU utilizes multiple-input multiple output.
