OPTICAL NETWORK UNIT (ONU) FOR LOW LATENCY PACKET TRANSMISSION IN TIME DIVISION MULTIPLEXING-PASSIVE OPTICAL NETWORK (TDM-PON), METHOD OF OPERATING THE SAME, AND APPARATUS FOR CONTROLLING ONU
First Claim
1. A method of operating an Optical Network Unit (ONU) for low latency packet transmission in a Time Division Multiplexing-Passive Optical Network (TDM-PON), the method comprising:
- receiving, from a base station, first bandwidth allocation information regarding a bandwidth allocated by the base station to a terminal for uplink packet transmission; and
transmitting a bandwidth allocation request, which is based on the received first bandwidth allocation information, to an Optical Line Terminal (OLT) before completing packet reception from the base station.

19. An apparatus for controlling an Optical Network Unit (ONU) for low latency packet transmission in a Time Division Multiplexing-Passive Optical Network (TDM-PON), the apparatus comprising:
-
a first bandwidth allocation information manager configured to receive, from a base station, first bandwidth allocation information regarding a bandwidth allocated by the base station to a terminal for uplink packet transmission, and analyze the received first bandwidth allocation information to estimate an amount of packets to be received from the base station; a storage configured to store a first duration and a second duration; and a bandwidth allocation request time determiner configured to determine a bandwidth allocation request time by considering the stored first duration and second duration, wherein the apparatus controls the ONU to transmit the bandwidth allocation request, which includes the estimated amount of packets, to the OLT at the determined bandwidth allocation request time. - View Dependent Claims (20)
