Figure 10From: Relay Architectures for 3GPP LTE-Advanced(a) Downlink sum rate in one sector versus mobile station position for base station coordination, shared relaying, and direct transmission. A reuse factor 6 is shown because the curves are more separated in this case. By adapting between shared relaying and direct transmission depending on user location, the rates of base station coordination can be approached. (b) The geometry of the sector, explaining the x- and y-axes of part (a).Back to article page
