SUBCARRIER ALLOCATION METHOD FOR UPSTREAM BANDWIDTH ARBITRATION AND METHOD FOR TRANSMITTING UPLINK DATA IN OFDMA-PON
摘要
<p>Disclosed are a method for allocating upstream bandwidth resources and a method for transmitting uplink data in an orthogonal frequency division multiplexing-passive optical network. The method for allocating the upstream bandwidth resources according to an embodiment of the present invention comprises the steps of: receiving information of a queue state from optical network devices; and allocating upstream bandwidth resources by providing a two dimensional upstream bandwidth map, which is composed of a subcarrier and a time resource through a frame synchronized in a certain period based on the information of the queue state received from each optical network device, to each optical network device.</p>
