A unified service‐based capability exposure framework for closed‐loop network automation
Transactions on Emerging Telecommunications Technologies, Volume 33, Issue 11, November 2022., 2022 In this article, we motivate the need for an enhanced network exposure functionality for network automation. We motivate it by revising the state of the art, propose a candidate architecture, and proof its feasibility with a real world testbed.

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 The pursuit of achieving higher data rates in 5G and beyond has triggered numerous technological advancements. One of these is spectrum sharing between Mobile Network Operators (MNOs). In this work, we investigate the spectrum trading between two MNOs with disparate traffic loads in heterogeneous networks. A radio resource sharing technique is proposed

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021 In this paper, we first give an overview of the coexistence of cellular with IEEE 802.11 technologies in the unlicensed bands. We then present a coexistence mechanism for Fifth‐Generation (5G) New Radio on Unlicensed (NR‐U) small cells located within buildings to coexist with the IEEE 802.11ad/ay, also termed as Wireless Gigabit (WiGig).
