1. A wireless transmit/receive unit (WTRU) comprising:
- a transceiver operatively coupled to a processor configured to receive a first radio resource control (RRC) message from a cell of a first radio access technology (RAT);
wherein in response to the first RRC message, a first medium access control (MAC) entity is configured for the first RAT;
wherein the first RRC message includes information for configuring the WTRU to communicate with a first primary cell of the first RAT;
the transceiver operatively coupled to the processor is further configured to receive a second RRC message a second MAC entity is configured for the second RAT;
wherein the second RRC message includes information for configuring the WTRU to communicate with a second primary cell for the second RAT;
wherein first MAC entity and the second MAC entity are different; and
the transceiver operatively coupled to the processor is further configured to communicate with the first RAT and the second RAT simultaneously.

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.

7. A method comprising:
-
receiving, by a wireless transmit/receive unit (WTRU), a first radio resource control (RRC) message from a cell of a first radio access technology (RAT); in response to the received first RRC message, configured a first medium access control (MAC) entity for the first RAT;
wherein the first RRC message includes information for configuring the WTRU to communicate with a first primary cell of the first RAT;receiving, by the WTRU, a second RRC message from a cell of the first RAT; in response to the second RRC message, configuring a second MAC entity for the second RAT;
wherein the second RRC message includes information for configuring the WTRU to communicate with a second primary cell for the second RAT;
wherein first MAC entity and the second MAC entity are different; andcommunicating, by the WTRU, with the first RAT and the second RAT simultaneously. - View Dependent Claims (8, 9, 10, 11, 12, 17, 18, 19, 20)

21. A base station comprising:
-
a transceiver operatively coupled to a processor configured to transmit a first radio resource control (RRC) message to a wireless transmit/receive unit (WTRU);
wherein in response to the first RRC message, a first medium access control (MAC) entity is configured for a first radio access technology (RAT);
wherein the first RRC message includes information for configuring the WTRU to communicate with a first primary cell of the first RAT;the transceiver operatively coupled to the processor is further configured to transmit a second RRC message using the first RAT;
wherein in response to the second RRC message, a second MAC entity is configured for the second RAT;
wherein the second RRC message includes information for configuring the WTRU to communicate with a second primary cell for the second RAT;
wherein first MAC entity and the second MAC entity are different; andthe transceiver operatively coupled to the processor is further configured to receive a communication over the first RAT from the WTRU while the WTRU simultaneously communicates using the second RAT. - View Dependent Claims (22, 23)
