Split Precoding and Split Prefiltering Between a Central Unit and a Distributed Unit of a Generation Node-B (GNB)

A base station comprising:

• a central unit (CU) and a distributed unit (DU) coupled by an interface;
• wherein the DU is coupled to a plurality of antennas,
• wherein the CU is configured to receive signal quality information from the DU via the interface, wherein the signal quality information is related to one or more signal quality measurements.

A method for operating a base station, the method comprising:

• sending signal quality information from a distributed unit (DU) of the base station to a central unit (CU) of the base station, wherein the DU is coupled to a plurality of antennas, wherein the signal quality information is related to one or more signal quality measurements.

A non-transitory memory medium storing program instructions, wherein the program instructions, when executed by one or more processors, cause the one or more processors to:

• send signal quality information from a distributed unit (DU) of a base station to a central unit (CU) of the base station, wherein the DU is coupled to a plurality of antennas, wherein the signal quality information is related to one or more signal quality measurements.
