Summary: IAB is an important new feature in 5G NR that enables rapid and cost-effective millimeter-wave deployments through self-backhauling in the same spectrum. Research shows that IAB solutions can provide massive coverage advantages for early mmWave rollouts with only a small number of fiber-connected base stations.

Summary: The paper presents a cooperative mechanism called DEC TDMA, based on clustered TDMA concept, to achieve synchronization between the front end and back end using time stamping. The proposed mechanism significantly reduces delay at heavy loads, provides better energy efficiency for a large number of ONUs, and exhibits better delay performance due to the implementation of dynamic bandwidth allocation while providing data slots in TDMA.

Summary: This research generalizes the definition of multilevel code (MLC) for $n$n user cases and discusses two power allocation schemes based on the spectral efficiency (SE) criterion and symbol error rate (SER) criterion. Simulation-based performance analysis shows that the best user fairness and bit error rate performance can be obtained in a two-user MLC-SER scheme.

Summary: Solar power passive optical network-based fiber-wireless access systems are popular for providing coverage in areas without power grid. This paper introduces two novel mechanisms, wake-up and time-out, to reduce ONU energy consumption and mitigate the effectiveness of man-in-the-middle attacks. Formal verification results show these goals were effectively achieved.
