Abstract

The disclosure relates to a 5 th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4 th generation (4G) communication system such as long term evolution (LTE). A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) is provided. The method includes the steps of generating an RIC control message, and transmitting the RIC control message to an E2 node, wherein the RIC control message includes an information element (IE) for indicating a radio resource control (RRC) message type.

Claims (60)

1 . A method performed by a Near-real time (RT) radio access network (RAN) intelligent controller (RIC), the method comprising:

generating an RIC control message; and

transmitting, 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.

2 . The method of claim 1 ,

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).

3 . The method of claim 1 , 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.

4 . The method of claim 1 , 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.

5 . The method of claim 4 ,

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.

6 . A method performed by an E2 node, the method comprising:

receiving, from a Near-real time (RT) radio access network (RAN) intelligent controller (RIC), an 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.

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 ,

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.

14 . An E2 node comprising:

a transceiver; and

a processor coupled to the transceiver, and configured to:

receive, from a Near-real time (RT) radio access network (RAN) intelligent controller (RIC), an 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.

15 . The E2 node of claim 14 ,

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).

16 . The E2 node of claim 14 , 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.

17 . The E2 node of claim 14 ,

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.
