Abstract:
Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.
