Avoiding TCI reselection due to active BWP switching

A method for wireless communications by a user equipment (UE), comprising:

• receiving transmission configuration indication (TCI) state information for communication via multiple bandwidth parts (BWPs), wherein the TCI state information indicates one or more quasi co-location (QCL) type assumptions, wherein the one or more QCL type assumptions include at least a first QCL type assumption;
• and
• monitoring, according to a BWP switch, for at least a first reference signal (RS) of the one or more QCL type assumptions based on one or more rules that define BWP switching for the one or more RSs of the one or more QCL type assumptions, wherein:
• the BWP switch is from a first BWP identifier (ID) to a second BWP ID,
• the one or more rules allow for a BWP ID of the first RS to be unspecified in the TCI state information, and
• when the BWP ID of the first RS is unspecified in the TCI state information, the one or more rules specify that the BWP ID of the first RS is to be the second BWP ID after the BWP switch.

An apparatus for wireless communications, comprising:

• at least one processor configured to:
• configure a UE with transmission configuration indication (TCI) state information for communication via multiple bandwidth parts (BWPs), wherein the TCI state information indicates one or more quasi co-location (QCL) type assumptions, wherein the one or more QCL type assumptions include at least a first QCL type assumption;
• and
• transmit, according to a BWP switch, one or more reference signals (RSs) of the one or more QCL type assumptions based on one or more rules that define BWP switching for the one or more RSs of the one or more QCL type assumptions, wherein:
• the BWP switch is from a first BWP identifier (ID) to a second BWP ID,
• the one or more rules allow for a BWP ID of a respective RS of the one or more RSs to be unspecified in the TCI state information, and
• when the BWP ID of the respective RS is unspecified in the TCI state information, the one or more rules specify that the BWP ID of the respective RS is to be the second BWP ID after the BWP switch;
• and
• a memory coupled with the at least one processor.
