wherein the DCI is associated with a physical layer level control for the UE.
7 . The method of claim 6 ,
wherein the RIC control message includes information indicating a radio access technology (RAT) type,
wherein the RAT type indicates one of a plurality of RATs, and
wherein the plurality of RATs comprises new radio (NR) or long-term evolution (LTE).
8 . The method of claim 6 ,
wherein the RIC control message further includes an ID of a data radio bearer (DRB) and information on a priority for the RIC control message.
9 . The method of claim 6 ,
wherein the RIC control message further includes information indicating a type of radio resource control (RRC) message, block error rate (BLER) information related to a modulation coding scheme (MCS), and offset information related to power control for the UE,
wherein the type of the RRC message is one of a plurality of types, and
wherein the plurality of types comprises an RRC reconfiguration or an RRC connection re-establishment.
10 . A Near-real time (RT) radio access network (RAN) intelligent controller (RIC) comprising:
a transceiver; and
a processor coupled to the transceiver, and configured to:
generate an RIC control message, and
transmit, to an E2 node, the RIC control message including an identifier (ID) of a user equipment (UE) and information on a scheduling control for the UE,
wherein the information on the scheduling control includes information indicating a format type of downlink control information (DCI) and the DCI for the UE, and
wherein the DCI is associated with a physical layer level control for the UE.
11 . The RIC of claim 10 ,
wherein the RIC control message includes information indicating a radio access technology (RAT) type,
wherein the RAT type indicates one of a plurality of RATs, and
wherein the plurality of RATs comprises new radio (NR) or long-term evolution (LTE).
12 . The RIC of claim 10 ,
wherein the RIC control message further includes an ID of a data radio bearer (DRB) and information on a priority for the RIC control message.
13 . The RIC of claim 12 ,
