Abstract—An increase in the network capacity is a requirement for modern LTE cellular networks. A part of the RF spectrum that is available for transmission is among the most important limiting factors. Such a problem can be solved in the LTE networks using unlicensed bands that are employed in alternative (e.g., Wi-Fi) technologies with the aid of a new LTE-LAA technology. In this work, we perform a comparative analysis of the channel access procedures for unlicensed bands that are described in the Wi-Fi standard and LTE-LAA specification and discuss open problems of coexisting technologies.
