10. A user equipment (UE) for a New Radio (NR) radio access network, the UE comprising processing circuitry and radio circuitry, and being configured to utilize the processing circuitry and radio circuitry to:
receive signaling that includes:
an uplink grant scheduling the UE with a signaling resource range of resources in a Physical Uplink Shared Channel (PUSCH) for transmission;
a feedback size indication indicating an expected size of a feedback resource range that comprises a continuous subset of a plurality of symbols of a slot in the signaling resource range that a network node expects to be used by the UE for Hybrid Acknowledgement Repeat Request (HARQ) feedback associated with at least one scheduling assignment; and
determine the expected size of the feedback resource range within the signaling resource range based on the feedback size indication;
determine an actual size of the feedback resource range needed for HARQ feedback is less than the expected size of the feedback resource range within the signaling resource range due to at least one missed scheduling assignment from the network node;
in response to the actual size of the feedback resource range being less than the expected size of the feedback resource range within the signaling resource range, pad at least a portion of the feedback resource range to meet the expected size of the feedback resource range within the signaling resource range; and
transmit Uplink Control Information (UCI) comprising the HARQ feedback on the feedback resource range in the signaling resource range of the PUSCH.
