Abstract
Systems and methods for communicating over multiple carriers are described herein. A predetermined event triggers the generation of scheduling information for two or more of the carriers. The predetermined event may comprise expiration of a timer set for at least one of the two or more carriers, storing data in a buffer having a higher transmission priority than data previously stored in the buffer, or changing at least one of the two or more carriers from being served by a first cell to being served by a second cell.
Claims20
A method used for communicating scheduling information in a wireless communication system, the method comprising:
- generating a first set of scheduling information bits on an anchor uplink carrier, the first set of scheduling information bits identifying an access terminal headroom for the anchor carrier;
- generating a second set of scheduling information bits on the anchor uplink carrier, the second set of scheduling information bits identifying a common queue length for each of the anchor carrier and a supplementary carrier;
- generating a third set of scheduling information bits on the supplementary uplink carrier, the third set of scheduling information bits identifying an access terminal headroom for the supplementary carrier;
- and
- generating a fourth set of scheduling information bits on the supplementary uplink carrier, the fourth set of scheduling information bits identifying feedback information related to inter-cell interference caused by the access terminal.
An apparatus for communicating scheduling information in a wireless communication system, the apparatus comprising:
- means for generating a first set of scheduling information bits on an anchor uplink carrier, the first set of scheduling information bits identifying an access terminal headroom for the anchor carrier;
- means for generating a second set of scheduling information bits on the anchor uplink carrier, the second set of scheduling information bits identifying a common queue length for each of the anchor uplink carrier and a supplementary uplink carrier;
- means for generating a third set of scheduling information bits on the supplementary carrier, the third set of scheduling information bits identifying an access terminal headroom for the supplementary uplink carrier;
- and
- means for generating a fourth set of scheduling information bits on the supplementary uplink carrier, the fourth set of scheduling information bits identifying feedback information related to inter-cell interference caused by the access terminal.
A computer program product for communicating scheduling information in a wireless communication system, comprising:
- a non-transitory computer-readable medium comprising code for:
- generating a first set of scheduling information bits on an anchor uplink carrier, the first set of anchor carrier bits identifying an access terminal headroom for the anchor uplink carrier;
- generating a second set of scheduling information bits on the anchor uplink carrier, the second set of anchor carrier bits identifying a common queue length for each of the anchor uplink carrier and a supplementary uplink carrier;
- generating a third set of scheduling information bits on the supplementary uplink carrier, the third set of scheduling information bits identifying an access terminal headroom for the supplementary uplink carrier;
- and
- generating a fourth set of scheduling information bits on the supplementary uplink carrier, the fourth set of scheduling information bits identifying feedback information related to inter-cell interference caused by the access terminal.
An apparatus for communicating scheduling information in a wireless communication system, the apparatus comprising:
- a processor, configured for generating a first set of scheduling information bits on an anchor uplink carrier, the first set of scheduling information bits identifying an access terminal headroom for the anchor uplink carrier, generating a second set of scheduling information bits on the anchor uplink carrier, the second set of scheduling information bits identifying a common queue length for each of the anchor uplink carrier and a supplementary uplink carrier, generating a third set of scheduling information bits on the supplementary uplink carrier, the third set of scheduling information bits identifying an access terminal headroom for the supplementary uplink carrier, and generating a fourth set of scheduling information bits on the supplementary uplink carrier, the fourth set of scheduling information bits identifying feedback information related to inter-cell interference caused by the access terminal;
- and
- a memory coupled to the processor for storing data.
