Simultaneous transmission of periodic CQI and ACK/NACK

Abstract:

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.
