Method and system for transferring wireless transmit/receive unit-specific information
The present invention is related to a method and system for transferring wireless transmit/receive unit (WTRU)-specific information to support enhanced uplink (EU) operation in a wireless communication system. A radio network controller (RNC) obtains WTRU-specific information, and transfers the WTRU-specific information to the Node-Bs. Each Node-B is configured to schedule uplink transmissions from a WTRU and utilizes the WTRU-specific information in operation of EU transmissions.
1. A method for enhanced uplink (EU) operation, the method comprising:
a Node-B receiving a radio link setup message from a radio network controller (RNC) for EU operation for a wireless transmit/receive unit (WTRU), the radio link setup message being generated by the RNC based on WTRU-specific information including EU capability of the WTRU;
the Node-B sending scheduling information for an EU transmission to the WTRU; and
the Node-B receiving an EU transmission from the WTRU based on the scheduling information.
2. The method of claim 1 wherein the Node-B receives the radio link setup message at an initiation of a service for the WTRU.
3. The method of claim 1 wherein the WTRU-specific information includes at least one of information affecting data rates and throughput, information on physical and transport channel characteristics, and time division duplex (TDD)-specific parameters.
4. The method of claim 1 wherein the WTRU-specific information is updated each time the WTRU-specific information changes.
5. The method of claim 1 further comprising:
the Node-B reserving resources and configuring a radio link for the EU operation based on the radio link setup message.
6. A Node-B for enhanced uplink (EU) operation, the Node-B comprising:
circuitry configured to receive a radio link setup message from a radio network controller (RNC) for EU operation for a wireless transmit/receive unit (WTRU), the radio link setup message being generated by the RNC based on WTRU-specific information including EU capability of the WTRU;
circuitry configured to send scheduling information for an EU transmission to the WTRU; and
circuitry configured to receive an EU transmission from the WTRU based on the scheduling information.
7. The Node-B of claim 6 wherein the radio link setup message is received at an initiation of a service for the WTRU.
8. The Node-B of claim 6 wherein the WTRU-specific information includes at least one of information affecting data rates and throughput, information on physical and transport channel characteristics, and time division duplex (TDD)-specific parameters.
9. The Node-B of claim 6 wherein the WTRU-specific information is updated each time the WTRU-specific information changes.
10. The Node-B of claim 6 further comprising:
circuitry configured to reserve resources and configure a radio link for the EU operation based on the radio link setup message.
