Simultaneous transmission of periodic CQI and ACK/NACK
Methods and systems for simultaneous transmission of periodic Channel Quality Indicator (CQI) and Hybrid Automatic Repeat Request (HARQ) Acknowledgement (ACK)/Negative Acknowledgement (NACK) are presented. According to one aspect, a method of operation of a node comprises configuring the node to have two differently sized sets of resources. The method includes determining that the node needs to report feedback, the feedback comprising at least a periodic CQI feedback. The method includes, upon determining that the node needs to report the feedback, selecting one of the differently sized sets of resources to be used for reporting the feedback, wherein the larger set is selected when the node needs to also report a HARQ feedback, and wherein the smaller set is selected when the node does not need to also report a HARQ feedback. The method includes reporting the feedback on the selected set of resources.
1. A method of operation of a node configured to have two differently sized sets of resources, the method comprising:
determining that the node needs to report feedback, the feedback comprising at least a periodic Channel Quality Indicator (CQI) feedback;
upon determining that the node needs to report the feedback, selecting a set of the two differently sized sets of resources to be used for reporting the feedback, wherein a larger set of the two differently sized sets of resources is selected when the feedback also comprises a Hybrid Automatic Repeat Request (HARQ) feedback, and wherein a smaller set of the two differently sized sets of resources is selected when the feedback does not also comprise the HARQ feedback; and
reporting the feedback on the selected set.
2. The method of claim 1 wherein the node is configured to have more than two differently sized sets of resources.
3. The method of claim 2 wherein one of the more than two differently sized sets of resources is selected according to a number of bits that comprise the feedback.
4. The method of claim 2 wherein one of the more than two differently sized sets of resources is selected according to a number of bits that comprise the HARQ feedback.
5. The method of claim 1 wherein the node receives an indication of which one of the more than two differently sized sets of resources to use for reporting the feedback.
6. The method of claim 5 wherein the node receives the indication via Downlink Control Information (DCI) or Media Access Control (MAC) control signaling.
7. The method of claim 5 wherein the selection is based at least in part on the received indication.
8. The method of any of claim 1 wherein the selection is based at least in part on the number of bits that comprise the feedback.
9. A node, configurable to have two differently sized sets of resources, the node comprising:
at least one processor;
memory comprising instructions executable by the at least one processor whereby the node is operable to:
determine that the node needs to report feedback, the feedback comprising at least a periodic Channel Quality Indicator (CQI) feedback;
upon determining that the node needs to report the feedback, select a set of the two differently sized sets of resources to be used for reporting the feedback, wherein a larger set of the two differently sized sets of resources is selected when the node needs to also report a Hybrid Automatic Repeat Request (HARQ) feedback, and wherein a smaller set of the two differently sized sets of resources is selected when the node does not need to also report the HARQ feedback; and
report the feedback on the selected set.
10. The node of claim 9 wherein the node is configured to have more than two differently sized sets of resources.
11. The node of claim 10 wherein one of the more than two differently sized sets of resources is selected according to a number of bits that comprise the feedback.
12. The node of claim 10 wherein one of the more than two differently sized sets of resources is selected according to a number of bits that comprise the HARQ feedback.
13. The node of claim 9 wherein the node receives an indication of which one of the more than two differently sized sets of resources to use for reporting the feedback.
14. The node of claim 13 wherein the selection is based at least in part on the received indication.
15. The node of claim 9 wherein the selection is based at least in part on the number of bits that comprise the feedback.
