Handling collision with synchronization signal block reception
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a set of resources to be used for reception of a synchronization signal block (SSB) overlaps at least one of a set of resources to be used for a first uplink transmission or a set of resources to be used for a second uplink transmission. The set of resources to be used for the first uplink transmission may overlap the set of resources to be used for the second uplink transmission. The first uplink transmission and the second uplink transmission may have a same priority index value. The UE may resolve an overlap between the first uplink transmission and the second uplink transmission and then resolve an overlap associated with the reception of the SSB. Numerous other aspects are described.
