Systems and Methods for Prioritizing Channel State Information Reports

Abstract

There is provided a method performed by a wireless device for prioritizing channel state information reports. The method comprises determining to transmit a portion of a plurality of channel state information reports that are each separately scheduled for transmission responsive to determining that the reports would be transmitted in a same slot with acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device. The method further comprises transmitting, by the wireless device in that slot, that portion of the channel state information and the acknowledgement information. There is also provided a method performed by a base station, a wireless device and a base station.

What is claimed is: 
     
         1 . A method performed by a wireless device for prioritizing channel state information reports, comprising:
 transmitting a portion of a plurality of channel state information reports that are each separately scheduled for transmission responsive to determining that the reports would be transmitted in a same slot with acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device.   
     
     
         2 . The method of  claim 1 , further comprising selecting the portion of the channel state information reports according to a prioritization criterion. 
     
     
         3 . The method of  claim 2 , wherein the prioritization criterion is associated with at least one of:
 a parameter of a channel state information report;   an identifier of a channel state information report; or   a time-domain behavior of a channel state information report.   
     
     
         4 . The method of  claim 1 , wherein transmitting a portion of a plurality of channel state information reports is performed responsive to determining that each report would be transmitted on at least one same symbol of the slot, whereon the acknowledgment information would also be transmitted. 
     
     
         5 . The method of  claim 1 , wherein each of the plurality of channel state information reports is scheduled for transmission on a respective Physical Uplink Control Channel, PUCCH. 
     
     
         6 . The method of  claim 1 , wherein each of the plurality of channel state information reports is a periodic and/or semi-persistent channel state information report. 
     
     
         7 . The method of  claim 1 , wherein the acknowledgement information is a Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK. 
     
     
         8 . The method of  claim 7 , wherein transmitting a portion of a plurality of channel state information reports is performed responsive to determining that at least two PUCCH resources each conveying a respective one or more of the channel state information reports overlap with a dynamically scheduled PUCCH conveying HARQ-ACK. 
     
     
         9 . A method performed by a network node, the method comprising:
 receiving, by the network node in a same slot, from a wireless device, at least one prioritized channel state information report selected from a plurality of channel state information reports and acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device, wherein each of the plurality of channel state reports and the acknowledgement information is separately scheduled for transmission by the wireless device in the same slot.   
     
     
         10 . The method of  claim 9 , further comprising separately scheduling the plurality of channel state information reports for transmission by the wireless device. 
     
     
         11 . The method of  claim 9 , wherein the at least one prioritized channel state information report is selected from a plurality of channel state information based on a prioritization criterion. 
     
     
         12 . The method of  claim 9 , wherein the at least one prioritized channel state information report is received based on a prioritization criterion. 
     
     
         13 . The method of  claim 11 , wherein the prioritization criterion is associated with a time-domain behavior of a channel state information report. 
     
     
         14 . The method of any of  claim 11 , wherein the prioritization criterion is associated with at least one of:
 a parameter of a channel state information report; or   an identifier of a channel state information report.   
     
     
         15 . The method of  claim 9 , wherein said receiving is on at least one symbol of the slot. 
     
     
         16 . The method of  claim 9 , wherein each of the plurality of channel state information reports is scheduled for transmission on a respective Physical Uplink Control Channel, PUCCH. 
     
     
         17 . The method of  claim 9 , wherein the acknowledgement information is a Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK. 
     
     
         18 . A wireless device comprising:
 processing circuitry and memory, the memory containing instructions executable by the   processing circuitry whereby the wireless device is configured to:   determine to transmit a portion of a plurality of channel state information reports that are each separately scheduled for transmission responsive to determining that the reports would be transmitted in a same slot with acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device; and   transmit, by the wireless device in that slot, that portion of the channel state information and the acknowledgement information.   
     
     
         19 . A base station comprising:
 processing circuitry and memory, the memory containing instructions executable by the processing circuitry whereby the base station is configured to:   receive, by the network node in a same slot, from a wireless device, at least one prioritized channel state information report selected from a plurality of channel state information reports and acknowledgement information indicating whether data was successfully or unsuccessfully received by the wireless device, wherein each of the plurality of channel state reports and the acknowledgement information is separately scheduled for transmission by the wireless device in the same slot.
