Abstract
In a time division multiple access point-to-multipoint transmission network, data is transmitted from a central station to local stations in multiframes containing a plurality of frames and a single free period allowing transmit time measurements and reflectometry measurements. Data is transmitted from the local stations to the central station in the form of multiframes containing a plurality of frames and a single free period allowing transmit time measurements and reflectometry measurements, each frame including subframes sent by the local stations, and each local station sending one or more of the subframes contained in a frame. The multiframes are constructed in a way that underuses the data sources, to obtain free periods between the frames, and by time-shifting the frames to construct a single free period per multiframe. Applications include telecommunication networks.
