DOI: 10.1109/lwc.2020.3002800
Abstract: In this letter, an adaptive power allocation (APA) strategy is proposed for an uplink non-orthogonal multiple access (NOMA) with semi-grant-free (SGF) transmission, where one grant-based user (GBU) shares the same resource with other grant-free users… read more here.

DOI: 10.1109/twc.2022.3204265
Abstract: The proliferation of delay-sensitive Internet-of-Things (IoT) applications has ushered in a need for the statistical delay quality-of-service (QoS) guarantee for the applications. In this paper, we first derive an upper bound for the queuing delay… read more here.
