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 comprising:
transmitting, by a wireless transmit/receive unit (WTRU) to a wireless network, WTRU-specific information including enhanced uplink (EU) capability of the WTRU;
receiving, by the WTRU, an EU transmission schedule from the wireless network, the EU transmission schedule being based on the EU capability of the WTRU; and
transmitting, by the WTRU, an EU transmission to the wireless network in accordance with the received EU transmission schedule.
2. The method of claim 1 , wherein the WTRU receives the EU transmission schedule at an initiation of a service for the WTRU.
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 at least one time division duplex (TDD)-specific parameter.
6. The method of claim 1 , wherein the WTRU-specific information includes WTRU capability information with respect to high-speed downlink packet access (HSDPA).
7. The method of claim 1 , further comprising:
transmitting updated WTRU-specific information each time the WTRU-specific information changes;
receiving an updated EU transmission schedule in response to the wireless network receiving the updated WTRU-specific information; and
transmitting an EU transmission to the wireless network in accordance with the updated EU transmission schedule.
8. The method of claim 7 , wherein the WTRU-specific information is periodically sent to the wireless network and wherein the wireless network sends the updated EU transmission schedule to the WTRU on the condition that the updated WTRU-specific information has changed.
9. The method of claim 1 , wherein the WTRU-specific information, EU transmission schedule, and EU transmissions are transmitted via a wireless communication interface between the WTRU and a Node-B in the wireless network.
10. The method of claim 1 , wherein the wireless network and WTRU are compliant with Third Generation Partnership Project standards.
11. A wireless transmit/receive unit (WTRU) comprising:
a transmitter configured to send to a wireless network, WTRU-specific information including enhanced uplink (EU) capability of the WTRU; and
a receiver configured to receive an EU transmission schedule from the wireless network, the EU transmission schedule being based on the EU capability of the WTRU,
wherein the transmitter is further configured to send an EU transmission to the wireless network in accordance with the received EU transmission schedule.
12. The WTRU of claim 11 , wherein the WTRU receives the EU transmission schedule at an initiation of a service for the WTRU.
13. The WTRU of claim 11 , wherein the WTRU-specific information includes information affecting data rates and throughput.
14. The WTRU of claim 11 , wherein the WTRU-specific information includes information on physical and transport channel characteristics.
15. The WTRU of claim 11 , wherein the WTRU-specific information includes at least one time division duplex (TDD)-specific parameter.
16. The WTRU of claim 11 , wherein the WTRU-specific information includes WTRU capability information with respect to high-speed downlink packet access (HSDPA).
17. The WTRU of claim 11 , wherein:
the transmitter is further configured to send updated WTRU-specific information each time the WTRU-specific information changes;
the receiver is further configured to receive an updated EU transmission schedule in response to the wireless network receiving the updated WTRU-specific information; and
the transmitter further configured to send an EU transmission to the wireless network in accordance with the updated EU transmission schedule.
18. The WTRU of claim 17 , wherein the transmitter is further configured to send the updated WTRU-specific information periodically to the wireless network and wherein the wireless network sends the updated EU transmission schedule to the receiver on the condition that the WTRU-specific information has changed.
19. The WTRU of claim 11 , wherein the WTRU-specific information, EU transmission schedule, and EU transmissions are transmitted via a wireless communication interface between the WTRU and a Node-B in the wireless network.
20. The WTRU of claim 11 , wherein the wireless network and WTRU are compliant with Third Generation Partnership Project standards.
