Title: Method and device for managing a shared transmission medium based on a TDMA/TDD scheme

Abstract: There is disclosed a method and a device for managing a transmission medium shared between a set of wireless network devices which comprises a plurality of stations and a Radio Resource Management (RRM) unit. The method is based on a time division scheme carried out by said RRM unit. Time is divided in a series of Frame Time Intervals (FTIs), which are split into a given number n of Time Intervals (TIs), each TI having a respective duration (D). The ownership of each TI is dedicated to a group of TI owner devices (TOG), selected among the set of devices. Each TOG comprises a given number k of transmitting devices, which are allowed to transmit over the transmission medium during the TI considered, and a given number m of receiving devices, which listen to the transmission medium during this TI, where m and k are strictly positive integer.
