Indication methods for synchronization signal block configuration changes

An apparatus for wireless communications at a first network entity, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a configuration of a plurality of synchronization signal blocks to be transmitted by the first network entity;
• identify that downlink traffic is to be transmitted on resources indicated by the identified configuration for at least one synchronization signal block of the plurality of synchronization signal blocks;
• transmit, to a second network entity that is a serving network entity for a user equipment (UE), a message indicating that a transmission of the at least one synchronization signal block of the plurality of synchronization signal blocks is canceled, wherein the message indicates resources for a signal to be transmitted by the first network entity as an alternative to the canceled at least one synchronization signal block;
• and
• transmit, to the UE based at least in part on the message, the signal using the indicated resources.

• and
• transmit, to a user equipment (UE) served by the first network entity, a message indicating that a transmission of the at least one synchronization signal block of the plurality of synchronization signal blocks by the second network entity is canceled and indicating resources for a signal to be transmitted by the second network entity as an alternative to the canceled at least one synchronization signal block.
