- Abstract
- Provided are an apparatus and a method for allocating a bandwidth for providing a low-latency fronthaul service in a passive optical network. An bandwidth allocating method performed by a bandwidth allocating apparatus included in an OLT includes receiving an actual report message requesting bandwidth allocation from at least one ONU for wired subscribers connected to the OLT, receiving radio scheduling information for at least one ONU for mobile connected to the OLT from a central unit (CU)/digital unit (DU), generating a virtual report message using the radio scheduling information received from the CU/DU, allocating a transmission bandwidth for the at least one ONU for wired subscribers and the at least one ONU for mobile through the received actual report message and the generated virtual report message, and transmitting the allocated transmission bandwidth to the ONU for wired subscribers and the ONU for mobile using a grant message.
