optimized proprietary receiver transparent techniques. The characteristics of each type of CoMP
architecture are summarized in Table 8.1. An advantage of intra-site CoMP is that significant amount of
exchange of information is possible since this communication is within a site and does not involve the
backhaul (connection between base stations). Inter-site CoMP involves the coordination of multiple sites
for CoMP transmission. Consequently, the exchange of information will involve backhaul transport. This
type of CoMP may put additional burden and requirement upon the backhaul design.
