To improve the performance of LTE cellular networks operating in the licensed frequency spectrum, a new LTE-LAA technology has been developed that allows LTE devices to transmit data in unlicensed frequency bands already used by Wi-Fi devices. The channel access method in LTE-LAA networks, as well as in Wi-Fi networks, is based on the mechanism of carrier sense with collision avoidance; however, LTE-LAA transmission can only begin at the boundary of licensed slots. In this work, we develop a mathematical model for the joint operation of LTE-LAA and Wi-Fi networks, which allows to assess the fairness of the distribution of channel resources between LTE-LAA stations and Wi-Fi stations depending on the duration of the licensed slot, the regulation of which will become possible as part of the New Radio technology of fifth generation cellular networks.
