Despite its notable importance, backhauling has - thus far - been a largely overlooked issue. However, driven by the uptake of small cell networks, current dedicated backhaul solutions are no longer viable for mobile operators, calling for novel deployment and backhaul-aware access strategies. In this paper, following the market's latest developments in infrastructure sharing, the authors investigate the uplink performance improvement when using a spatially-close open access small cell over one operator's carrier and simultaneously a direct access over another carrier. An important constituent of their work is the optimization problem of joint access and in-band (over-the-air) backhaul for the small cell link.
