Handling Sounding Reference Signaling

Abstract

There is described a method of operating a user equipment in a radio access network. The method comprises transmitting signaling based on a sounding reference signaling schedule, the sounding reference signaling schedule scheduling transmission of sounding reference signaling in a first time interval, wherein the first time interval overlaps, in an overlap time interval, with a second time interval, for which physical channel signaling is scheduled, wherein transmitting signaling comprises transmitting, in the overlap time interval, the physical channel signaling omitting the scheduled sounding reference signaling. The disclosure also pertains to related devices and methods.

What is claimed is: 
     
         1 . A method of operating a user equipment in a radio access network, the method comprising:
 transmitting signaling based on a sounding reference signaling schedule, the sounding reference signaling schedule scheduling transmission of sounding reference signaling in a first time interval, wherein the first time interval overlaps, in an overlap time interval, with a second time interval for which physical channel signaling is scheduled, wherein transmitting signaling comprises transmitting, in the overlap time interval, the physical channel signaling, while, in the overlap time interval, omitting the scheduled sounding reference signaling.   
     
     
         2 . The method of  claim 1 , wherein said transmitting comprises transmitting sounding reference signaling scheduled for a part of the first time interval not overlapping with the second time interval on the same carrier as the physical channel signaling. 
     
     
         3 . The method of  claim 2 , wherein the first and second time intervals are in the same slot. 
     
     
         4 . The method of  claim 1 , wherein said transmitting comprises transmitting the sounding reference signaling and the physical channel signaling on the same carrier. 
     
     
         5 . The method of  claim 1 , wherein the first time interval comprises more than one symbol time interval. 
     
     
         6 . The method of  claim 1 , wherein the sounding reference signaling schedule schedules the sounding reference signaling for transmission in a first frequency range, which is at least partly different from a second frequency range for which the physical channel signaling is scheduled. 
     
     
         7 . The method of  claim 1 , wherein the scheduled sounding reference signaling is omitted in an omitting time interval that comprises the overlap interval and that is larger than the overlap interval. 
     
     
         8 . The method of  claim 1 , wherein the scheduled sounding reference signaling is omitted in an omitting time interval based on an omitting configuration and/or one or more operational parameters. 
     
     
         9 . The method of  claim 1 , wherein the scheduled sounding reference signaling and the scheduled physical channel signaling pertain to the same carrier or carrier aggregation. 
     
     
         10 . The method of  claim 1 , wherein the sounding reference signaling and the physical channel signaling are scheduled with different scheduling messages. 
     
     
         11 . The method of  claim 1 , wherein the sounding reference signaling is scheduled for reciprocity signaling. 
     
     
         12 . The method of  claim 1 , wherein the sounding reference signaling schedule is dynamically scheduled or semi-static, and/or wherein the physical channel signaling is dynamically scheduled or semi-static. 
     
     
         13 . The method of  claim 1 , wherein the physical channel signaling is physical channel signaling on a Physical Uplink Control Channel (PUCCH). 
     
     
         14 . The method of  claim 1 , wherein the physical channel signaling corresponds to a short Physical Uplink Control Channel (PUCCH transmission spanning one or two symbol time intervals. 
     
     
         15 . User equipment for a radio access network, the user equipment comprising processing circuitry and radio circuitry and being configured to utilize the processing circuitry and radio circuitry to:
 transmit signaling based on a sounding reference signaling schedule, the sounding reference signaling schedule scheduling transmission of sounding reference signaling in a first time interval, wherein the first time interval overlaps, in an overlap time interval, with a second time interval, for which physical channel signaling is scheduled, wherein the user equipment is configured to transmit, in the overlap time interval, the physical channel signaling, while, in the overlap time interval, omitting the scheduled sounding reference signaling.   
     
     
         16 . The user equipment of  claim 15 , wherein the user equipment is configured to transmit sounding reference signaling scheduled for a part of the first time interval not overlapping with the second time interval on the same carrier as the physical channel signaling. 
     
     
         17 . The user equipment of  claim 16 , wherein the first and second time intervals are in the same slot. 
     
     
         18 . The user equipment of  claim 15 , wherein the user equipment is configured to transmit the sounding reference signaling and the physical channel signaling on the same carrier. 
     
     
         19 . The user equipment of  claim 15 , wherein the first time interval comprises more than one symbol time interval. 
     
     
         20 . The user equipment of  claim 15 , wherein the sounding reference signaling schedule schedules the sounding reference signaling for transmission in a first frequency range, which is at least partly different from a second frequency range for which the physical channel signaling is scheduled.
