NR-U and Wi-Fi Coexistence in sub-7 GHz bands: Implementation and Evaluation of NR-U Type 1 Channel Access in ns-3
Pages 36–44
PreviousChapterNextChapter
ABSTRACT
This paper addresses the challenge of optimising coexistence between 5G New Radio Unlicensed (NR-U) and Wi-Fi networks in the unlicensed spectrum at the sub-7 GHz bands. Leveraging the latest 3GPP standard TS 37.213, we align the listen-before-talk procedure with the latest standardisation, including implementation improvements. Through simulations, we demonstrate the advantages and limitations of the Type 1 channel access procedure. This work brings valuable insights, proposes solutions, and sets the groundwork for an NR-U extension crucial for future research. In particular, we evaluate the interplay between the NR-U numerologies and the channel access procedure set with different priorities.

- Performance analysis of spatially distributed LTE-U/NR-U and Wi-Fi networks: An analytical model for coexistence study
Abstract
To access an unlicensed channel, Wi-Fi follows the Listen Before Talk (LBT) mechanism, whereas LTE-U (and future New Radio in Unlicensed (NR-U) Patriciello etal., 2020; Lagen etal., 2019) adopts the ON–OFF duty-cycled mechanism to ...
