1. A wireless transmit/receive unit (WTRU) comprising:
- a transceiver and a processor configured to communicate with a first network node of a first radio access technology (RAT);
the transceiver and the processor further configured to receive a radio resource control (RRC) message of the first RAT from the first network node, wherein the RRC message includes a container including configuration information for a second RAT, wherein the configuration information includes radio bearer configuration information for the second RAT, wherein the first RAT and the second RAT are different RATs;
the transceiver and the processor further configured to communicate with both the first network node of the first RAT and a second network node of the second RAT, wherein communication with the second network node is based on the configuration information; and
the processor is further configured to have a single RRC state during communications with both the first RAT and the second RAT.

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.

6. A method comprising:
-
communicating, by a wireless transmit/receive unit (WTRU), with a first network node of a first radio access technology (RAT); receiving, by the WTRU, a radio resource control (RRC) message of the first RAT from the first network node, wherein the RRC message includes a container including configuration information for a second RAT, wherein the configuration information includes radio bearer configuration information for the second RAT, wherein the first RAT and the second RAT are different RATs; and communicating, by the WTRU, with both the first network node of the first RAT and a second network node of the second RAT, wherein communication with the second network node is based on the configuration information, and wherein the WTRU has a single RRC state during communications with both the first RAT and the second RAT. - View Dependent Claims (7, 8, 9, 10)
