Abstract

A method performed by a distributed unit (DU) including transmitting a management message including information for indicating a representative extended antenna-carrier (eAxC) port to a radio unit (RU) through a fronthaul interface is provided. The method includes transmitting a control plane message including section information and section extension information for resource allocation to the RU through the fronthaul interface. The section extension information is used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU. The representative eAxC port of the fronthaul interface is used for transmitting or receiving of the combined one U-plane message.

First claim

What is claimed is:

1 . A method performed by a distributed unit (DU), the method comprising:
transmitting a management message including information for indicating a representative extended antenna-carrier (eAxC) port to a radio unit (RU) through a fronthaul interface; and transmitting a control plane message including section information and section extension information for resource allocation to the RU through the fronthaul interface, wherein the section extension information is used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU, and wherein the representative eAxC port of the fronthaul interface is used for transmitting or receiving of the combined one U-plane message.

2 . The method of claim 1 ,
wherein the section extension information includes:
type information for indicating merging of user plane data,
beam group type information for indicating a type of beam grouping, and
port information for indicating a total number of one or more eAxC ports, and
wherein the one U-plane message includes downlink (DL) data or uplink (UL) data corresponding to the eAxC port and each eAxC port of the one or more eAxC ports.

3 . The method of claim 1 , wherein for each eAxC port of a plurality of eAxC ports for the combining, the one U-plane message includes:
a user data compression parameter for indicating a compression scheme in a physical resource block (PRB); an in-phase sample (isample) value for each resource element (RE) of the PRB; and a quadrature sample (qsample) value for each resource element (RE) of the PRB.

4 . The method of claim 1 , further comprising receiving the one U-plane message from the RU through the representative eAxC port of the fronthaul interface.

5 . The method of claim 1 ,
wherein the section extension information and other section extension information are used to combine a plurality of control plane (C-plane) messages into one C-plane message, and wherein the one C-plane message is transmitted to the RU through the representative eAxC port of the fronthaul interface.

6 . A method performed by a radio unit (RU), the method comprising:
receiving a management message including information for indicating a representative extended antenna-carrier (eAxC) port from a distributed unit (DU) through a fronthaul interface; and receiving a control plane (C-plane) message including section information and section extension information for resource allocation from the DU through the fronthaul interface, wherein the section extension information is used to combine a plurality of user plane (U-plane) messages into one U-plane message in the DU or the RU, and wherein the representative eAxC port of the fronthaul interface is used for transmitting or receiving of the combined one U-plane message.

7 . The method of claim 6 ,
wherein the section extension information includes:
type information for indicating merging of user plane data,
beam group type information for indicating a type of beam grouping, and
port information for indicating a total number of one or more eAxC ports, and
wherein the one U-plane message includes downlink (DL) data or uplink (UL) data corresponding to the eAxC port and each eAxC port of the one or more eAxC ports.

8 . The method of claim 6 , wherein for each eAxC port of a plurality of eAxC ports for the combining, the one U-plane message includes:
a user data compression parameter for indicating a compression scheme in a physical resource block (PRB); an in-phase sample (isample) value for each resource element (RE) of the PRB; and a quadrature sample (qsample) value for each resource element (RE) of the PRB.

9 . The method of claim 6 , further comprising transmitting the one U-plane message to the DU through the representative eAxC port of the fronthaul interface.

10 . The method of claim 6 ,
wherein the section extension information and other section extension information are used to combine a plurality of control plane (C-plane) messages into one C-plane message, and wherein the one C-plane message is received from the DU through the representative eAxC port of the fronthaul interface.

11 . An electronic device of a distributed unit (DU), the electronic device comprising:
