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 efficient scheduling of enhanced uplink (EU) transmissions, the method comprising:
a Node-B receiving wireless transmit/receive unit (WTRU)-specific information from a radio network controller (RNC), the WTRU-specific information being used for scheduling EU transmissions from a WTRU; and
the Node-B scheduling EU transmissions from the WTRU to the Node-B utilizing the WTRU-specific information.
2. The method of claim 1 wherein the WTRU-specific information includes WTRU capability information with respect to EU and high speed downlink packet access (HSDPA).
3. The method of claim 1 wherein the WTRU-specific information includes information affecting data rates and throughput.
4. The method of claim 1 wherein the WTRU-specific information includes information on physical and transport channel characteristics.
5. The method of claim 1 wherein the WTRU-specific information includes time division duplex (TDD)-specific parameters.
6. The method of claim 1 wherein the WTRU-specific information is received upon establishment of a service and upon any change of the WTRU-specific information.
7. The method of claim 1 wherein the WTRU-specific information is received periodically.
8. A Node-B for efficient scheduling of enhanced uplink (EU) transmissions, the Node-B comprising:
a receiver for receiving wireless transmit/receive unit (WTRU)-specific information from a radio network controller (RNC), the WTRU-specific information being used for scheduling EU transmissions from a WTRU; and
a scheduler configured to schedule EU transmissions from the WTRU to the Node-B utilizing the WTRU-specific information.
9. The Node-B of claim 8 wherein the WTRU-specific information includes WTRU capability information with respect to enhanced uplink (EU) and high speed downlink packet access (HSDPA).
10. The Node-B of claim 8 wherein the WTRU-specific information includes information affecting data rates and throughput.
11. The Node-B of claim 8 wherein the WTRU-specific information includes information on physical and transport channel characteristics.
12. The Node-B of claim 8 wherein the WTRU-specific information includes time division duplex (TDD)-specific parameters.
13. The Node-B of claim 8 wherein the WTRU-specific information is received upon establishment of a service and upon any change of the WTRU-specific information.
14. The Node-B of claim 8 wherein the WTRU-specific information is received periodically.
