Hierarchical content caching in fog radio access networks: ergodic rate and transmit latency
Publication Year: 2016,Page(s):1 - 14
Cited by: Papers (15)
In order to alleviate capacity constraints on the fronthaul and decrease the transmit latency, a hierarchical content caching paradigm is applied in the fog radio access networks (F-RANs). In particular, a specific cluster of remote radio heads is formed through a common centralized cloud at the baseband unit pool, while the local content is directly delivered at fog access points with edge cache ...Show More

Publication Year: 2016,Page(s):25 - 36
Cited by: Papers (7)
A Κ-tier uplink heterogeneous cellular network is modelled and analysed by accounting for both truncated channel inversion power control and biased user association. Each user has a maximum transmit power constraint and transmits data when it has sufficient transmit power to perform channel inversion. With biased user association, each user is associated with a base station (BS) that provides the ...Show More

Publication Year: 2016,Page(s):37 - 48
Cited by: Papers (3)
To mitigate interference on cell-edge users and improve fairness of the whole system, dynamic inter-cell interference coordination (ICIC) is one of the promising solutions. However, traditional dynamic ICIC is considered as an NP-hard problem and power variability further adds another dimension to this joint optimization issue, making it even more difficult to quickly reach a near-optimal solution...Show More

A novel spectrum handoff-based sensing-throughput tradeoff scheme in cognitive radio
Publication Year: 2016,Page(s):59 - 68
Cited by: Papers (6)
In cognitive radio (CR), there is a tradeoff between spectrum sensing time and throughput of secondary user (SU). In the conventional sensing-throughput tradeoff scheme, when the presence of the primary user (PU) is detected, the SU will stop forwarding data and wait to redetect the PU in the following frame, yielding great throughput loss. In order to improve the SU’s throughput, a novel sensing-...Show More
