Methods, systems, and devices for wireless communication are described. Devices may synchronize parameters associated with an encryption key to avoid a key mismatch. In a first example, a transmitter and a receiver may each update a respective parameter at each transmission occasion associated with semi-statically allocated resources, regardless of whether signaling is transmitted in the transmission occasion. In a second example, the transmitter and the receiver may each update the respective parameter based on a slot count, rather than at each transmission occasion. In a third example, the transmitter may indicate a value of a transmitter parameter to the receiver, for example in control signaling or in the signaling in each transmission occasion. In a fourth example, the receiver may be enabled to identify a skipped transmission occasion The receiver may be enabled with a feedback process to indicate the receiver recognized the associated transmission occasion was skipped.
