1. A method for mitigating Overlapping Basic Service Set (OBSS) interference in a wireless communications network, the method comprising:

  • receiving a pre-configured timing synchronization function (TSF) offset by a first device;

    storing the timing synchronization function (TSF) offset to a TSF offset bank component of the first access point (AP) device, wherein the TSF offset includes a timing offset between the first AP device and a plurality of other access point (AP) devices;

    determining a target beacon transmission time (TBTT) of the first AP devices based upon the stored TSF offset, wherein the TBTT includes a starting point of a super beacon interval;

    generating and allocating of at least one beacon interval from the super beacon interval by a processor, wherein the generated and allocated at least one beacon interval is used by the first AP for the wireless communications network; and

    collaborating and transmitting to the plurality of other AP devices a beacon frame that represents the generated at least one beacon interval, wherein the beacon frame includes the determined TBTT, a total number of beacon intervals in the super beacon interval, and an identification of the at least one beacon interval that is used by the first AP device, a media access address to identify the first access point as the transmitter, and a target beacon transmission time (TBTT) that is set to zero to reduce overhead in the beacon frame.
