Transmission configuration indicator state carrier configuration

A user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• receive radio resource configuration messages to configure a transmission configuration indicator state pool in a physical downlink shared channel-configuration in a bandwidth part, a component carrier, or a combination thereof, wherein the transmission configuration indicator state pool comprises a plurality of transmission configuration indicator states, the plurality of transmission configuration indicator states are configured for use in a list of carriers that comprises a list of QCL-TypeA resources, and each QCL-TypeA resource in the list of QCL-TypeA resources comprises a reference signal defined in a carrier of a list of carriers;
• receive a medium access control control element message that activates a subset of the plurality of transmission configuration indicator states for use;
• and
• receive a downlink control information signal that indicates a transmission configuration indicator state of the plurality of transmission configuration indicator states for a physical downlink shared channel, a physical downlink control channel, a physical uplink shared channel, a physical uplink control channel, or a combination thereof in a selected bandwidth part, a selected component carrier, or a combination thereof.

A base station, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
