An achievability scheme for downlink multicell processing with finite backhaul capacity: The general case

Abstract

In the general scenario of downlink multicell processing, we propose an achievability scheme for the case where the capacity of the backhaul links are limited. The achievability scheme proposed generalizes our earlier work of 2 base stations and 2 mobile users to an arbitrary number of base stations and users. Through numerical results, we demonstrate through example that in the medium range of finite backhaul capacity, our scheme outperforms other known achievability schemes.
