Abstract
Methods and apparatus for performing wireless communication in a wireless transmit/receive unit (WTRU) configured for multi-radio access technology (RAT) operation are disclosed. A method includes the WTRU wirelessly communicating information on a first operating frequency according to a first RAT. The WTRU also wirelessly communicates information on a second operating frequency according to a second RAT.

Claim
1. A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor, wherein
the processor and the transceiver are configured to:
receive messages on a first cell using a first radio access technology (RAT);
receive, on the first cell, a radio resource control (RRC) reconfiguration message, wherein the RRC reconfiguration message includes first information indicating to the WTRU to use a second cell using the first RAT, and second information indicating to the WTRU to use a third cell using a second RAT, wherein the first RAT and the second RAT are different RATs;
responsive to receiving the first information, initiate a first random access procedure on the second cell using the first RAT; and
responsive to receiving the second information, initiate a second random access procedure on the third cell using the second RAT.
2. The WTRU of claim 1, wherein the RRC reconfiguration message is associated with handover.
3. The WTRU of claim 1, wherein the processor and the transceiver are further configured to:
determine, based on the first random access procedure, first uplink timing information for the second cell using the first RAT; and
determine, based on the second random access procedure, second uplink timing information for the third cell using the second RAT.
4. The WTRU of claim 3, wherein uplink transmissions on the second cell using the first RAT are synchronized according to the first uplink timing information, and wherein uplink transmissions on the third cell using the second RAT are synchronized according to the second uplink timing information.
5. The WTRU of claim 1, wherein the first RAT is Long Term Evolution.
6. The WTRU of claim 1, wherein the processor and the transceiver are further configured to send, on the second cell using the first RAT, transmissions.
7. The WTRU of claim 6, wherein the transmissions sent on the second cell include uplink control information.
8. The WTRU of claim 6, wherein the transmissions sent on the second cell use security mechanisms for the first RAT.
9. The WTRU of claim 1, wherein the processor and the transceiver are further configured to send, on the third cell using the second RAT, transmissions.
10. The WTRU of claim 9, wherein the transmissions sent on the third cell use security mechanisms for the second RAT.
11. The WTRU of claim 1, wherein the RRC reconfiguration message is received on a first signaling radio bearer (SRB).
12. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving messages on a first cell using a first radio access technology (RAT);
receiving, on the first cell, a radio resource control (RRC) reconfiguration message, wherein the RRC reconfiguration message includes first information indicating to the WTRU to use a second cell using the first RAT, and second information indicating to the WTRU to use a third cell using a second RAT, wherein the first RAT and the second RAT are different RATs;
responsive to receiving the first information, initiating a first random access procedure on the second cell using the first RAT; and
responsive to receiving the second information, initiating a second random access procedure on the third cell using the second RAT.
13. The method of claim 12, wherein the RRC reconfiguration message is associated with handover.
14. The method of claim 12, further comprising:
determining, based on the first random access procedure, first uplink timing information for the second cell using the first RAT; and
determining, based on the second random access procedure, second uplink timing information for the third cell using the second RAT.
15. The method of claim 14, wherein uplink transmissions on the second cell using the first RAT are synchronized according to the first uplink timing information, and wherein uplink transmissions on the third cell using the second RAT are synchronized according to the second uplink timing information.
16. The method of claim 12, wherein the first RAT is Long Term Evolution.
17. The method of claim 12, further comprising sending on the second cell using the first RAT, transmissions.
18. The method of claim 17, wherein the transmissions sent on the second cell include uplink control information.
19. The method of claim 17, wherein the transmissions sent on the second cell use security mechanisms for the first RAT.
20. The method of claim 12, further comprising sending, on the third cell using the second RAT, transmissions.
21. The method of claim 20, wherein the transmissions sent on the third cell use security mechanisms for the second RAT.
22. The method of claim 12, wherein the RRC reconfiguration message is received on a first signaling radio bearer (SRB).
