Centralized coordinated scheduling in LTE-Advanced networks [PDF]

EURASIP Journal on Wireless Communications and Networking, 2017
This work addresses the problem associated with coordinating scheduling decisions among multiple base stations in an LTE-Advanced downlink network in order to manage inter-cell interference with a centralized controller. To solve the coordinated scheduling problem an integer non-linear program is formulated that, unlike most existing approaches, does ...
