Abstract

Claims (23)

1. A method, implemented by a base station, the method comprising:

sending a first downlink control information indicating that a wireless transmit/receive unit (WTRU) is to transmit uplink data on a first uplink channel;

sending an indication of logical channels that are subject to triggering of an uplink scheduling request;

receiving a plurality of a same value over a second uplink channel in response to a triggering condition, wherein the triggering condition is based on the indication of logical channels, wherein the second uplink channel is a control channel; and

sending a second downlink control information in accordance with the plurality of the same value over the second uplink channel.

2. The method of claim 1 , wherein the receiving the plurality of the same value is in response to the first downlink control information providing an insufficient amount to transmit uplink data over the first uplink channel.

3. The method of claim 1 , further comprising receiving, for a logical channel, an indication of a recommended uplink resource.

4. The method of claim 3 , wherein the indication of the recommended uplink resource is associated with a data rate.

5. The method of claim 3 , further comprising transmitting an uplink scheduling resource for the first uplink channel based on the received indication.

6. The method of claim 1 , wherein the receiving of the plurality of the same value is a request for an uplink scheduling resource.

7. A base station comprising:

a processor;

a receiver; and

a transmitter; wherein:

the processor and the transmitter are configured to transmit a first downlink control information indicating that a wireless transmit/receive unit (WTRU) is to transmit uplink data on a first uplink channel;

the processor and the transmitter are further configured to send an indication of logical channels that are subject to triggering of an uplink scheduling request;

the processor and the receiver are configured to receive, in response to a triggering condition, a plurality of a same value over a second uplink channel, wherein the triggering condition is based on the indication of logical channels, wherein the second uplink channel is a control channel; and

the processor and the transmitter are further configured to transmit a second downlink control information in accordance with the plurality of the same value over the second uplink channel.

8. The base station of claim 7 , wherein the reception of the plurality of the same value is in response to the first downlink control information providing an insufficient amount to transmit uplink data over the first uplink channel.

9. The base station of claim 7 , wherein the processor and the receiver are further configured to receive, for a logical channel, an indication of a recommended uplink resource.

10. The base station of claim 9 , wherein the indication of the recommended uplink resource is associated with a data rate.

11. The base station of claim 9 , wherein the processor and the transmitter are further configured to transmit an uplink scheduling resource for the first uplink channel based on the received indication.

12. The base station of claim 7 , wherein the reception of the plurality of the same value is a request for an uplink scheduling resource.
