Default communication configuration for communication across carriers

A method of communication at a base station, comprising:

• determining a default communication configuration comprising quasi-colocation information for a first carrier;
• sending the default communication configuration to a user equipment;
• sending a scheduling indication for the first carrier to the user equipment via a second carrier;
• determining that no control resource set is defined for the first carrier;
• determining another communication configuration based on the default communication configuration as a result of the determining that no control resource set is defined for the first carrier;
• and
• communicating information via the first carrier according to the scheduling indication, wherein the communication of the information is based on the other communication configuration.

A user equipment, comprising:

• an interface;
• and
• a processing circuit coupled to the interface and configured to:
• receive a default communication configuration comprising quasi-colocation information for a first carrier from a base station via the interface;
• receive a scheduling indication for the first carrier from the base station via a second carrier;
• determine that no control resource set is defined for the first carrier;
• elect to use the default communication configuration for communication based on the scheduling indication as a result of the determination that no control resource set is defined for the first carrier;
• and
• communicate information via the first carrier according to the scheduling indication, wherein the communication of the information is based on the default communication configuration.
