Abstract: A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.

Abstract: Presented herein are mechanisms to reduce collisions in deployments with Wi-Fi and Shared Access LTE (SAC-LTE) equipment as well SAC-LTE equipment from multiple operators. The mechanisms enhance the baseline energy detection mechanism by incorporating methods to decode cross-technology physical layer elements and media access control (MAC) layer elements in the Wi-Fi system to elements in the SAC-LTE system. The methods described improve the detection potential for transmitters, thereby reducing chances of cross-technology collisions.

Abstract: In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.
