1. A method, performed by a wireless device, of uplink control signaling to a network node in a wireless communication network, the method comprising:
triggering a Scheduling Request (SR) corresponding to a single logical channel having data to transmit;
mapping a Scheduling Request ID that uniquely identifies only the single logical channel to one or more Physical Uplink Control Channel (PUCCH) resources;
in response to a mapped SR PUCCH resource overlapping with a PUCCH carrying uplink control information (UCI), encoding an indication of the Scheduling Request ID directly in the UCI; and
transmitting to the network node, on the PUCCH, the UCI including the Scheduling Request ID indication.
