Game-Theoretic Optimization for Machine-Type Communications Under QoS Guarantee
Yu Gu, Qimei Cui, Qiang Ye +1
Massive machine-type communication (mMTC) is a new focus of services in fifth generation (5G) communication networks. The associated stringent delay requirement of end-to-end (E2E)…
Distributed Layered Grant-Free Non-Orthogonal Multiple Access for Massive MTC
Hui Jiang, Qimei Cui, Yu Gu +3
Grant-free transmission is considered as a promising technology to support sporadic data transmission in massive machine-type communications (mMTC). Due to the distributed manner,…
Effective Capacity Analysis in Ultra-Dense Wireless Networks with Random Interference
Yu Gu, Qimei Cui, Yu Chen +3
Ultra-dense networks (UDNs) provide a promising paradigm to cope with exponentially increasing mobile traffic. However, little work has to date considered unsaturated traffic with…
Optimal Scheduling across Heterogeneous Air Interfaces of LTE/WiFi Aggregation
Yu Gu, Qimei Cui, Wei Ni +2
LTE/WiFi Aggregation (LWA) provides a promising approach to relieve data traffic congestion in licensed bands by leveraging unlicensed bands. Critical challenges arise from provisi…
Preserving Reliability to Heterogeneous Ultra-Dense Distributed Networks in Unlicensed Spectrum
Qimei Cui, Yu Gu, Wei Ni +4
This article investigates the prominent dilemma between capacity and reliability in heterogeneous ultra-dense distributed networks, and advocates a new measure of effective capacit…
Effective Capacity of Licensed-Assisted Access in Unlicensed Spectrum for 5G: From Theory to Application
Qimei Cui, Yu Gu, Wei Ni +1
License-assisted access (LAA) is a promising technology to offload dramatically increasing cellular traffic to unlicensed bands. Challenges arise from the provision of quality-of-s…
