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.

Abstract
Systems and methods for implementing a mitigation of overlapping basic service set (OBSS) interference are disclosed. Synchronization of access point (AP) devices may be based upon a transmission synchronization function (TSF) offset between the AP devices. In an implementation, collaboration between the AP devices may include exchanging of beacon schedule frames through a controller, or over the air media access.
