Methods, systems, and devices for notifying puncturing of a physical downlink shared channel (PDSCH) are described. In some examples, a user equipment (UE) may receive, from a base station, a first control message identifying a set of resources used for transmissions by the base station. The UE may receive a second control message that includes an indication of a procedure used by the base station for a collision between the set of resources and a downlink channel transmitted to the first UE by the base station. In some examples, the UE may receive and decode signals on the downlink channel according to the indicated procedure.
