Electronic device and method for indicating allocated resource region

A method performed by a radio unit (RU), the method comprising:

• receiving, from a distributed unit (DU), a control plane (C-plane) message including section information for indicating a resource area and section extension information,
• wherein the section extension information includes resource information allocated for each user equipment (UE) of a plurality of UEs related to a radio unit (RU) connected to the DU,
• wherein the resource information includes first information and second information,
• wherein the first information indicates a start resource block of resource blocks continuously allocated to a corresponding UE in the resource area, and
• wherein the first information and the second information are used to indicate the resource blocks continuously allocated to the corresponding UE;
• and
• performing, based on the resource information allocated for each user equipment (UE), an uplink (UL) communication.

A device for performing functions of a distributed unit (DU), the device comprising:

• at least one fronthaul transceiver including communication circuitry;
• at least one processor including processing circuitry;
• and
• memory, including one or more storage media, storing instructions,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the device to:
• generate a control plane (C-plane) message including section information for indicating a resource area and section extension information, and
• transmit the C-plane message to a radio unit (RU),
• wherein the section extension information includes resource information allocated for each user equipment (UE) of a plurality of UEs related to a radio unit (RU) connected to the DU,
• wherein the resource information includes first information and second information,
• wherein the first information indicates a start resource block of resource blocks continuously allocated to a corresponding UE in the resource area, and
• wherein the first information and the second information are used to indicate the resource blocks continuously allocated to the corresponding UE.
