Abstract

The disclosure relates to resource allocation. In accordance with the disclosed method first information regarding a first direction of a duplex communication link and second information regarding a second direction of the duplex communication link is provided for a node. The first information and the second information are processed, and channel resources are allocated for the first direction and the second direction of the duplex communication link based at least partially on said processing.

Claims

1. A method, comprising:

receiving first information regarding a first direction of a duplex communication link;

receiving second information regarding a second direction of the duplex communication link;

processing the first information and the second information; and

allocating channel resources for the first direction and the second direction of the duplex communication link based at least partially on said processing.

2. A method as claimed in claim 1, wherein the channel resource comprises at least one of a channel, subchannel, carrier frequency, a time slot, a time-frequency slot, a transmit beam, and a receive beam.

3. A method as claimed in claim 1, comprising determining a joint allocation parameter, and allocating resources based on the joint allocation parameter.

4. A method as claimed in claim 1, wherein said first and second information comprise at least one of channel information and interference information.

5. A method as claimed in claim 1, wherein said first and second information comprise channel specific information;

the channel specific information comprise at least one of information regarding channel power, signal to interference ratio, bit error rate, channel capacity, channel throughput, channel utilization, channel specific buffer, channel quality, channel occupancy, channel availability, tolerable delay, channel state information, subchannel preferences, and data rate demands.

6. A method as claimed in claim 1, comprising weighting at least one of the first information and the second information.

7. A method as claimed in claim 1, wherein the processing comprises combining information based on at least one of additive, non-additive and multiplicative combining.

8. A method as claimed in claim 1, wherein the processing comprises combining performance matrices.

9. A method as claimed in claim 1, comprising determining the first information by a transmitting node, receiving the second information from a receiving node, and processing the first and second information in the transmitting node to provide said allocation of channel resources.

10. A method as claimed in claim 1, comprising receiving the second information via a feedback channel.

11. A method as claimed in claim 1, comprising allocation of resources for at least one other link based on said processing.

12. An apparatus, comprising:

a receiver configured to receive first information regarding a first direction of a duplex communication link; and

second information regarding a second direction of the duplex communication link; and

a processor configured to

process the first information and the second information; and

allocate channel resources for the first direction and the second direction of the duplex communication link based at least partially on said processing.

13. An apparatus as claimed in claim 12, wherein the channel resource comprises at least one of a channel, subchannel, carrier frequency, a time slot, and a time-frequency slot.

14. An apparatus as claimed in claim 12, further comprising a controller configured to determine a joint allocation parameter and allocate resources based on the joint allocation parameter.

15. An apparatus as claimed in claim 12, configured to allocate said channel resources based on channel specific information;

the channel specific information comprise at least one of information regarding channel power, interference, signal to interference ratio, bit error rate, channel capacity, channel throughput, channel utilization, channel specific buffer, channel quality, channel occupancy, channel availability, tolerable delay, subchannel preferences, channel state information, and data rate demands.

16. An apparatus as claimed in claim 12, configured to apply a weight to at least one of the first information and the second information.

17. An apparatus as claimed in claim 12, configured to combine the first information and the second information based on at least one of additive, non-additive or multiplicative combining.

18. An apparatus as claimed in claim 12, configured to allocate resources for at least one other link based on said processing.

19. An apparatus comprising:

an interface configured to receive a first information regarding a first direction of a duplex communication link from a transmitting node and to send a second information regarding a second direction of the duplex communication to the transmitting node; and

at least one data processor configured to determine the second information, to process the first information and the second information, and to allocate channel resources for the second direction of the duplex communication link based at least partially on the processing.

20. An apparatus as claimed in claim 19, comprising a user equipment for communication in a multi-user environment.
