1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a base station, a first semi-persistent scheduling configuration that indicates resources for a plurality of downlink semi-persistent scheduling transmissions to the UE;
receiving, from the base station, a first downlink control information communication associated with the first semi-persistent scheduling configuration, wherein the first downlink control information communication comprises an indication of a relationship between a timing of acknowledgment feedback for the plurality of downlink semi-persistent scheduling transmissions and a timing of the resources for the plurality of downlink semi-persistent scheduling transmissions, wherein the indication of the relationship comprises an unallowed value; and
identifying the first downlink control information communication as an error case based at least in part on the relationship comprising the unallowed value.
