21. A lower-layer split central unit (LLS-CU) in a network node of a wireless communication system including a radio unit (RU), the LLS-CU comprising:
a processor circuit;
a network interface coupled to the processor circuit and configured to communicate with the RU, and
a memory coupled to the processor circuit, the memory comprising machine readable program instructions that, when executed by the processor circuit, cause the LLS-CU to perform operations comprising:
generating a data-associated control information (DACI) message that includes an indication that a radio unit (RU) should generate a set of beamforming weights for forming an antenna beam between the RU and a user equipment (UE) of the wireless communication system; and
transmitting the DACI message to the RU.
