What is it about?
This paper tackles the challenge of improving coexistence between 5G New Radio Unlicensed (NR-U) and Wi-Fi networks in the unlicensed sub-7 GHz bands. Using the latest 3GPP standards, we update the listen-before-talk procedure to ensure it meets current regulations. Our simulations highlight the strengths and weaknesses of the Type 1 channel access method. This study provides valuable insights, suggests solutions, and lays the foundation for future NR-U research. Specifically, we assess the interplay bwteen different NR-U subcarrier spacing configurations and the channel access priorities.
