26. An apparatus for wireless communication at a user equipment (UE), comprising: a processor, memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to:
identify that the UE is configured to transmit via a plurality of periodic semi-persistently scheduled (SPS) resources on a shared channel accessed in a half-duplex manner;
mute transmission of a scheduled message during at least one of the SPS resources in order to monitor for transmissions from another device during the at least one SPS resource based at least in part on a probability parameter whose value is based on occurrence of a triggering event, wherein the muting comprises skipping transmission of the scheduled message during the at least one SPS resource;
detect a transmission from the other device on the shared channel during the at least one SPS resource; and
adjust, based at least in part on detection of the transmission from the other device during the at least one SPS resource, transmission of the scheduled message to a different resource in order to avoid overlapping transmissions from the other device.
