Techniques for updating transmission configuration indicator states

A method for wireless communications at a base station, comprising:

• transmitting, to a user equipment (UE), an indication to update a transmission configuration indicator state of a first component carrier associated with a neighboring cell, wherein the transmission configuration indicator state is updated differently depending on whether the transmission configuration indicator state is associated with one of:
• a first reference signal associated with a serving cell and a second reference signal associated with the neighboring cell;
• and
• transmitting a message comprising a neighboring cell update rule for updating the transmission configuration indicator state across multiple component carriers associated with the first component carrier.

An apparatus for wireless communications at a 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, from a serving cell, an indication to update a transmission configuration indicator state of a first component carrier associated with a neighboring cell, wherein the transmission configuration indicator state is updated differently depending on whether the transmission configuration indicator state is associated with one of:
• a first reference signal associated with the serving cell and a second reference signal associated with the neighboring cell;
• determine, in accordance with a neighboring cell update rule, whether to update the transmission configuration indicator state across multiple component carriers associated with the first component carrier based at least in part on the first component carrier being associated with the neighboring cell;
• and
• update the transmission configuration indicator state of at least the first component carrier in accordance with the neighboring cell update rule.
