Synchronized framing scheduling methods and systems for ofdma based wireless systems

An OFDMA based Access Point (AP) for scheduling one or more Framing Slots between the AP and a plurality of stations (STAs) in an orthogonal frequency division multiple access (OFDMA) based wireless communication network, said AP comprising:

• at least one synchronization source for time synchronization in said OFDMA wireless communication system;
• at least one transceiver used to transmit or receive wireless signals;
• and
• at least one processor in communication with said at least one transceiver, said processor is used to control the transceiver and wherein the processor comprises instructions to:
• synchronize the plurality of STAs within the network using one or more synchronization signals over the air transmitted between the AP and the plurality of STAs;
• allocate the one or more Framing Slots, wherein each Framing Slot of said one or more Framing Slots having a fixed time duration, and wherein each Framing Slot of the one or more Framing Slots is divided into DL burst transmission and UL burst transmission periods, wherein the DL burst transmission period comprises one or more DL Data Units Bursts
• and wherein the UL burst transmission period comprises one or more UL Data Units Bursts continuously schedule by said AP the one or more DL Data Units Bursts during said DL transmission period to said one or more STAs;
• and
• continuously send said one or more UL Data Unit Bursts by said one or more STAs to said AP.
