摘要：
Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumptions, such as QCL assumptions for combined single-DCI (downlink control information) and multi-DCI mTRP (multiple transmission reception point) scenarios. A method that may be performed by a user equipment (UE) includes receiving signaling configuring the UE with a first index value associated with a first plurality of control resource sets (CORESETS) and a second index value associated with a second plurality of CORESETS. The UE may receive at least one medium access control (MAC) control element (CE) that activates a set of transmission configuration indicator (TCI) states, indicates one of the first or second index values, and that maps at least one TCI codepoint in downlink control information (DCI) to two TCI states. The UE may determine one or more TCI states to use for receiving one or more transmissions based, at least in part, on the mapping.
