Abstract
A TSN-based distributed antenna system including a headend unit, one or more TSN switches, and one or more remote units and a fronthaul transport network constituted by the headend unit, the TSN switch, and the remote unit is provided. The packet-based fronthaul network constituted by the headend unit, the TSN switch, and the remote unit transmits traffic in a time-deterministic manner while minimizing packet loss through Ethernet to which TSN standards are applied.
Claims20
A distributed antenna system for sending a downlink signal of a base station of a mobile communication system to a user terminal, the distributed antenna system comprising:
- a packet-based network;
- a headend unit connected with the base station of the mobile communication system to receive a radio signal, generate an Ethernet frame including the received radio signal, and transmit the generated Ethernet frame to the packet-based network connected thereto;
- one or more remote units configured to send the radio signal included in the Ethernet frame transmitted through the packet-based network to a user terminal through an antenna;
- and
- at least one time sensitive network (TSN) switch included on an Ethernet frame transmission path between the headend unit and the remote unit.
A distributed antenna system for transmitting an uplink signal of a user terminal to a mobile communication base station system, the distributed antenna system comprising:
- a packet-based network;
- a headend unit configured to transmit a radio signal in an Ethernet frame transmitted through the packet-based network to a base station of a mobile communication system connected thereto;
- one or more remote units configured to receive a radio signal transmitted from a user terminal through an antenna, generate an Ethernet frame including the received radio signal, and transmit the generated Ethernet frame to the packet-based network connected thereto;
- and
- at least one time sensitive network (TSN) switch included on an Ethernet frame transmission path between the headend unit and the remote unit.
