A proportional fair scheduling for multicarrier transmission systems
Hoon Kim,Youngnam Han +1 more
TLDR
A simple system is presented, which proves its superiority over other schemes for multicarrier transmission, e.g. extended round robin and the PF scheduling scheme for the HDR system.Abstract:
This letter extends the proportional fair (PF) scheduling proposed in the high data rate (HDR) system to multicarrier transmission systems. It is known that the PF allocation (F. P. Kelly et al. (1998)) results in the maximization of the sum of logarithmic average user rates. We propose a PF scheduling that assigns users to each carrier while maximizing the sum of logarithmic average user rates.read more

A Survey of Downlink Non-orthogonal Multiple Access for 5G Wireless Communication Networks
TL;DR: A simple NOMA model with two users served by a single-carrier simultaneously to illustrate its basic principles is discussed and a more general model with multicarrier serving an arbitrary number of users on each subcarrier is discussed.

Rate control for communication networks: shadow prices, proportional fairness and stability
TL;DR: This paper analyses the stability and fairness of two classes of rate control algorithm for communication networks, which provide natural generalisations to large-scale networks of simple additive increase/multiplicative decrease schemes, and are shown to be stable about a system optimum characterised by a proportional fairness criterion.

Information capacity and power control in single-cell multiuser communications
Raymond Knopp,Pierre A. Humblet +1 more
TL;DR: By examining the bit error-rate with antipodal signalling, it is shown that an increase in capacity over a perfectly-power controlled (Gaussian) channel can be achieved, especially if the number of users is large, and the inherent diversity in multiuser communications over fading channels is shown.
