Spatial quasi co-location indication for control resource set and downlink bandwidth part

A method of wireless communication by a network entity, the method comprising:

• signaling, based on a first downlink (DL) bandwidth part (BWP) of a control resource set (CORESET) lacking dedicated signaling of quasi co-location (QCL) information for a user equipment (UE), QCL information in physical downlink shared channel (PDSCH) configuration information for a second DL BWP regarding a beam, the beam for a physical downlink control channel (PDCCH) transmission on the CORESET in the first DL BWP, wherein the QCL information in the PDSCH configuration information is configured to indicate QCL information for determining the beam for the PDCCH transmission on the CORESET in the first DL BWP;
• and
• transmitting the PDCCH transmission to the UE on the CORESET in the first DL BWP using the beam;
• wherein the second DL BWP is a fixed DL BWP.

A user equipment (UE) for wireless communication, the UE comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the processor is configured to:
• determine, for monitoring for a physical downlink control channel (PDCCH) transmission on an initial control resource set (CORESET) having a CORESET identifier of 0 in an initial downlink (DL) bandwidth part (BWP) having a BWP identifier of 0, quasi co-location (QCL) information from physical downlink shared channel (PDSCH) configuration information for a reference DL BWP;
• and
• monitor for the PDCCH transmission on the initial CORESET in the initial DL BWP using the determined QCL information.
