Abstract: Certain aspects of the present disclosure provide techniques for detecting a potential collision between a scheduled uplink transmission and a synchronization signal block (SSB) and transmitting the scheduled uplink transmission. For example, in cases of inter-cell multi-transmission and reception points (multi-TRP), a user equipment (UE) may not be capable of simultaneously transmitting and receiving on the multiple serving cells. A first serving cell may indicate to the UE of SSB indices that are actually transmitted for a second serving cell. If there is a slot collision between one of the SSB to be transmitted and a scheduled uplink transmission, the UE may not be able to handle such collision. The present disclosure provides techniques for detecting a potential collision between a scheduled uplink transmission and one of the SSBs and transmitting the scheduled uplink transmission when one or more conditions are met.
