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.

A method performed by a distributed unit (DU), the method comprising:
- transmitting, to a radio unit (RU) through a fronthaul interface, a management plane (M-plane) message indicating a plurality of extended antenna-carrier (eAxC) ports that include a representative eAxC port;
- transmitting, to the RU through the fronthaul interface, a control plane (C-plane) message including section information for resource allocation and section extension information that indicates the RU to combine uplink data of the plurality of eAxC ports into one user plane (U-plane) message;
- and
- receiving, from the RU through the fronthaul interface, the U-plane message of the representative eAxC port, that includes the uplink data of the plurality of eAxC ports,
- wherein
- the uplink data of the plurality of eAxC ports are associated with a same subcarrier spacing.
A method performed by a radio unit (RU), the method comprising:
- receiving, from a distributed unit (DU) through a fronthaul interface, a management plane (M-plane) message indicating a plurality of extended antenna-carrier (eAxC) ports that include a representative eAxC;
- receiving, from the DU through the fronthaul interface, a control plane (C-plane) message including section information for resource allocation and section extension information that indicates the RU to combine uplink data of the plurality of eAxC ports into one user plane (U-plane) message;
- and
- transmitting, to the DU through the fronthaul interface, the U-plane message of the representative eAxC port, that includes the uplink data of the plurality of eAxC ports,
- uplink data of the plurality of eAxC ports are associated with a same subcarrier spacing.
A distributed unit (DU) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the at least one transceiver,
- wherein the at least one processor is configured to:
- control the at least one transceiver to transmit, to a radio unit (RU) through a fronthaul interface, a management plane (M-plane) message indicating a plurality of extended antenna carrier (eAxC) ports that include a representative eAxC port,
- control the at least one transceiver to transmit, to the RU through the fronthaul interface, a control plane (C-plane) message including section information for resource allocation and section extension information that indicates the RU to combine uplink data of the plurality of eAxC ports into one user plane (U-plane) message, and
- control the at least one transceiver to receive, from the RU through the fronthaul interface, the U-plane message of the representative eAxC port, that includes the uplink data of the plurality of eAxC ports, and
- wherein the uplink data of the plurality of eAxC ports are associated with a same subcarrier spacing.
A radio unit (RU) comprising:
- at least one transceiver;
- and
- at least one processor coupled to the at least one transceiver,
- wherein the at least one processor is configured to:
- control the at least one transceiver to receive, from a distributed unit (DU) through a fronthaul interface, a management plane (M-plane) message indicating a plurality of extended antenna-carrier (eAxC) ports that include a representative eAxC port,
- control the at least one transceiver to receive, from the DU through the fronthaul interface, a control plane (C-plane) message including section information for resource allocation and section extension information that indicates the RU to combine uplink data of the plurality of eAxC ports into one user plane (U-plane) message, and
- control the at least one transceiver to transmit, to the DU through the fronthaul interface, the U-plane message of the representative eAxC port, that includes the uplink data of the plurality of eAxC ports, and
- wherein the uplink data of the plurality of eAxC ports are associated with a same subcarrier spacing.
