Apparatus, methods, and computer-readable media for acknowledgment feedback for groupcast option 1 sidelink communication are disclosed herein. An example method of wireless communication at a receiving user equipment (UE) includes determining whether a data signal associated with a groupcast transmission from a transmitting UE is decodable at the receiving UE and obtaining measurements of the data signal when the data signal is decodable at the receiving UE. The example method also includes determining whether the measurements exceed a threshold and transmitting a first type of feedback to the transmitting UE when the measurements do not exceed the threshold. An example method of wireless communication at a transmitting UE includes receiving, from a receiving UE over a sidelink channel, feedback comprising the first type of feedback when the first UE is determined to monitor for the first type of feedback and a second type of feedback from a plurality of UEs.
