Abstract
A method, performed by a first distributed unit (DU), of performing communication in a wireless communication system may include performing, based on resource usage of the first DU, configuration of an inter-DU interface with a second DU requiring a connection with the first DU, obtaining information about at least one first radio unit (RU) to be migrated to the second DU from among at least one RU connected to the first DU, stopping resource allocation for at least one uplink packet associated with at least one user equipment (UE) connected to the first RU, and transmitting, based on the configured inter-DU interface, to the second DU, at least one downlink packet required to be transmitted to the first RU or the at least one UE.
Claims17
A method, performed by a first distributed unit (DU), of performing communication in a wireless communication system, the method comprising:
- performing, based on resource usage of the first DU, configuration of an inter-DU interface with a second DU requiring a connection with the first DU;
- obtaining information about at least one first radio unit (RU) to be migrated to the second DU from among at least one RU connected to the first DU;
- stopping resource allocation for at least one uplink packet associated with at least one user equipment (UE) connected to the first RU;
- and
- transmitting, based on the configured inter-DU interface, to the second DU, at least one downlink packet required to be transmitted to the first RU or the at least one UE,
- wherein the first DU comprises a first F1 splitter,
- wherein the second DU comprises a second F1 splitter, and
- wherein packets are transmitted and received between the first DU and the second DU via the inter-DU interface using the first F1 splitter and the second F1 splitter.
A method, performed by a second distributed unit (DU), of performing communication in a wireless communication system, the method comprising:
- performing, based on resource usage of a first DU, configuration of an inter-DU interface with the first DU;
- obtaining information about at least one first radio unit (RU) to be migrated to the second DU from among at least one RU connected to the first DU;
- and
- receiving, based on the configured inter-DU interface, from the first DU, at least one downlink packet required to be transmitted to the first RU or at least one user equipment (UE) connected to the first RU,
- wherein resource allocation for at least one uplink packet associated with the at least one UE is stopped based on a request from the first DU,
- wherein the first DU comprises a first F1 splitter,
- wherein the second DU comprises a second F1 splitter, and
- wherein packets are transmitted and received between the second DU and the first DU via the inter-DU interface using the first F1 splitter and the second F1 splitter.
A method, performed by an operations, administration, and maintenance (OAM) entity, of performing communication in a wireless communication system, the method comprising:
- determining, based on resource usage of a first distributed unit (DU), whether to configure an inter-DU interface with a second DU;
- identifying at least one first radio unit (RU) to be migrated to the second DU from among at least one RU connected to the first DU;
- and
- transmitting information about the first RU to the first DU or the second DU,
- wherein control of at least one downlink packet and at least one uplink packet is performed between the first DU and the second DU, based on the information about the first RU,
- wherein the first DU comprises a first F1 splitter,
- wherein the second DU comprises a second F1 splitter, and
- wherein packets are transmitted and received between the second DU and the first DU via the inter-DU interface using the first F1 splitter and the second F1 splitter.
