Handling sounding reference signaling
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.
1. A method of operating a user equipment in a New Radio (NR) radio access network, the method comprising:
receiving control signaling that schedules sounding reference signaling and physical channel signaling to be transmitted by the user equipment on the same carrier and in the same slot as one another, the sounding reference signaling and the physical channel signaling being scheduled for transmission in respective first and second time intervals that are in the slot and that overlap in time in an overlap time interval, wherein the first time interval has a duration of 2 or 4 symbol time intervals, wherein the physical channel signaling is physical channel signaling on a Physical Uplink Control Channel (PUCCH); and
based on scheduling of the sounding reference signaling according to the control signaling, transmitting signaling such that, in the overlap time interval, the physical channel signaling is transmitted omitting the scheduled sounding reference signaling, and wherein the signaling is transmitted such that sounding reference signaling scheduled for a part of the first time interval not overlapping with the second time interval is transmitted on the same carrier as the physical channel signaling.
2. The method according to claim 1 , wherein the signaling comprises the sounding reference signaling and the physical channel signaling.
3. The method according to claim 1 , wherein the first time interval and the second time interval have at least one common symbol time interval and/or only partially overlap.
