1. A baseband processor configured to perform operations comprising:
outputting a periodic transmission to one or more receiving UEs;
collecting negative acknowledgement (NACK) statistics for the periodic transmission according to one or more feedback-based collision detection parameters, wherein the one or more feedback-based collision detection parameters indicate that the NACK statistics are grouped into a plurality of datasets corresponding to different sets of transmissions for the periodic transmission; and
performing corrective action based on the collected NACK statistics and at least one of the one or more feedback-based collision detection parameters, wherein the plurality of datasets are sequentially evaluated to determine whether to perform the corrective action.
