Cloud radio access network (C-RAN) has been proposed as a core network in the fifth-gene rati on mobile communications system. The computing resources are clustered as a pool that is centralised management as a cloud. The pool provides flexible capabilities to satisfy variant demands with large scale processing. This work stands on an operator perspective to analyse a centralised management mechanism...
Soft frequency reuse (SFR) has been proposed as a technique to address the problem of intercell interference (ICI) in cellular networks. A major challenge facing SFR implementation is the efficient allocation of scarce base station (BS) resources like bandwidth and power. This challenge further motivates the need for accurate network modelling, a requirement for optimal SFR algorithms. Particularly,...
We consider a wireless-powered multi-pair relaying network with a multi-antenna relay which applies the energy beamforming (BF) for wireless powering and zero-forcing BF for the information relaying. For the network, power and time allocation problems are tackled to maximize the minimum achievable rate among the device pairs with the instantaneous channel station information (CSI) and statistical...
The growing demand for spectrum resources and the limited licensed spectrum have led to widespread concern about the coexistence of LTE and WiFi in the unlicensed spectrum. Since LTE and WiFi are two different systems, many solutions have been proposed to solve their coexistence problems, including the coexistence scheme based on blank subframe allocation. This paper presents a scheme that uses Q-learning...
Optimal configuration of base station (BS) parameters is a key requirement in current cellular networks. For acceptable user (UE) performance, the bandwidth and transmit power parameters of each BS need to be intelligently chosen. Soft frequency reuse (SFR) is a resource allocation algorithm that specifies efficient frequency and power distribution for different locations within a BS. By classifying...
