Techniques for dynamically updating a search space of a sidelink control channel

A method for wireless communication at a second user equipment (UE), comprising:

• identifying a configuration of a search space for a first UE including a first plurality of monitoring occasions of a sidelink control channel;
• transmitting, to the first UE, signaling indicating an update to the search space, the update associated with one or more monitoring occasions of the sidelink control channel;
• and
• transmitting, to the first UE, a first part of sidelink control information over a subset of a second plurality of monitoring occasions of the sidelink control channel based at least in part on the configuration of the search space and the update to the search space.

An apparatus for wireless communication at a first user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a configuration of a search space for the first UE including a first plurality of monitoring occasions of a sidelink control channel;
• receive, from a second UE, signaling indicating an update to the search space, the update associated with one or more monitoring occasions of the sidelink control channel;
• monitor a second plurality of monitoring occasions of the sidelink control channel based at least in part on the configuration of the search space and the update to the search space;
• and
• receive a first part of sidelink control information based at least in part on the monitoring.
