METHOD AND DEVICE FOR MULTICARRIER DIVISION MULTIPLEXING SYSTEM

摘要

Provided are a method and device applied to a multicarrier division multiplexing system. The method comprises: obtaining a start time of an uplink grant from an optical line terminal of a time division multiplexing passive optical network system; according to a synchronization associated timestamp, determining a location of a multicarrier division multiplexing-based transmission unit corresponding to the start time of the uplink grant, wherein the multicarrier division multiplexing transmission unit is a symbol or a frame; and according to an average capacity parameter of time quantum, determining a resource block location corresponding to the start time, wherein the average capacity parameter indicates that the total capacity of the transmission unit is averaged to an integral number of time quanta contained in the transmission unit, and a time quantum unit indicates a time unit of the time division multiplexing passive optical network system.
