1. A method for adaptive channel access, the method comprising:
adaptively adjusting, by a small base station (SBS), access parameters for small cells to ensure quality of service (QoS) to cellular users while minimizing a collision probability to WiFi users, wherein minimizing the collision probability to the WiFi users comprises:
keeping or decreasing an optimal backoff window size when the collision probability to the WiFi users is below a threshold value; andincreasing the optimal backoff window size when the collision probability to the WiFi users is above the threshold value.
