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
A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor, wherein
the transceiver is configured to communicate, using a first radio access technology (RAT), radio resource control (RRC) information;
the transceiver is further configured to receive, over a first signaling radio bearer (SRB) of the first RAT, a RRC message including configuration information for a second RAT, wherein the configuration information for the second RAT includes a system information (SI) information element for the second RAT, and wherein the first RAT and the second RAT are different RATs; and
the transceiver is further configured to communicate using both the first RAT and the second RAT.
2. The WTRU of claim 1, wherein the RRC message includes configuration information for a second SRB of the second RAT.
3. The WTRU of claim 1, wherein the RRC information of the first RAT is communicated using a first format and RRC information of the second RAT is communicated using a second format different than the first format.
4. The WTRU of claim 1, wherein the RRC message further includes radio bearer information elements for the second RAT.
5. The WTRU of claim 1, wherein a first medium access control (MAC) entity is used for the first RAT, wherein:
the processor is configured to establish a second MAC entity for the second RAT, in response to the RRC message; and
the transceiver is configured to communicate using both the first MAC entity and the second MAC entity.
6. The WTRU of claim 1, wherein a single RRC state is used for both the first RAT and the second RAT.
7. The WTRU of claim 6, wherein a single RRC instance and a single RRC state machine is used for both the first RAT and the second RAT.
8. The WTRU of claim 1, wherein the first RAT is long term evolution.
9. The WTRU of claim 1, wherein a first WTRU identity is associated with the first RAT and a second WTRU identity is associated with the second RAT, wherein the WTRU uses the first WTRU identity for communications using the first RAT and the second WTRU identity for communications using the second RAT.
10. The WTRU of claim 1, wherein the configuration information is included in a container.
11. A method performed by a wireless transmit/receive unit (WTRU) comprising:
communicating, using a first radio access technology (RAT), radio resource control (RRC) information;
receiving, over a first signaling radio bearer (SRB) of the first RAT, a RRC message including configuration information for a second RAT, wherein the configuration information for the second RAT includes a system information (SI) information element for the second RAT, and wherein the first RAT and the second RAT are different RATs; and
communicating using both the first RAT and the second RAT.
12. The method of claim 11, wherein the RRC message includes configuration information for a second SRB of the second RAT.
13. The method of claim 11, wherein the RRC information of the first RAT is communicated using a first format and RRC information of the second RAT is communicated using a second format different than the first format.
14. The method of claim 11, wherein the RRC message further includes radio bearer information elements for the second RAT.
15. The method of claim 11, wherein a first medium access control (MAC) entity is used for the first RAT, further comprising:
establishing a second MAC entity for the second RAT, in response to the RRC message; and
communicating using both the first MAC entity and the second MAC entity.
16. The method of claim 11, wherein a single RRC state is for both the first RAT and the second RAT.
17. The method of claim 16, wherein a single RRC instance and a single RRC state machine is used for both the first RAT and the second RAT.
18. The method of claim 11, wherein the first RAT is long term evolution.
19. The method of claim 11, wherein a first WTRU identity is associated with the first RAT and a second WTRU identity is associated with the second RAT, wherein the WTRU uses the first WTRU identity for communications using the first RAT and the second WTRU identity for communications using the second RAT.
20. The method of claim 11, wherein the configuration information is included in a container.
