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

A method for managing a transmission medium shared between a set of wireless network devices comprising a plurality of stations and a Radio Resource Management (RRM) unit based on a time division scheme carried out by said RRM unit, wherein said set of devices comprises at least one subset of devices including a Local RRM (L-RRM) unit, said method comprising the steps of:

• said RRM unit providing a series of Frame Time Intervals (FTIs),
• splitting each FTI into a given number n of Time Intervals (TIs), each having a respective duration (D), where n is a given integer;
• dedicating at least one TI to only said L-RRM unit (L-RRM TI);
• splitting said L-RRM TI into q Local TIs (L-TIs), each having a respective duration, where q is a given integer;
• and
• dedicating the ownership of at least one L-TI to a group of L-TI owner devices (L-TOG) selected among said subset of devices, said L-TOG comprising a given number r of transmitting devices, which are allowed to transmit over said transmission medium during said L-TI and a given number of s of receiving devices, which listen to said transmission medium during said L-TI, where r and s are strictly positive integers,
• wherein the number q of L-TIs in a given L-RRM TI, and the respective duration and L-TOG of each one of said q L-TIs are determined dynamically by the L-RRM unit.
