Multiplexing and prioritization techniques for uplink signaling and non-serving cell synchronization signals
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multiplexing and prioritization techniques for uplink signaling and non-serving cell synchronization signals. In some aspects, a user equipment (UE) and a network entity may support a prioritization rule according to which the UE and the network entity may enable uplink multiplexing with a set of non-serving cell synchronization signal blocks (SSBs). For example, an uplink signal and a set of non-serving cell SSBs may be scheduled for the UE and may at least partially overlap in time and the UE may prioritize one of the uplink signal or the set of non-serving cell SSBs in accordance with the prioritization rule. The prioritization rule may be associated with a scheduling offset of the uplink signal or may be associated with whether the set of non-serving cell SSBs are indicated for measurement at the UE.
