Looks like I re-visit CoMP every Q1 of the year. Couple of years back, I had posted a primer on CoMP here and last year I had a slide on schemes and deployments here. With Release-11 out of the door and Release-12 getting in full swing in the standards, its time to re-visit this topic in a bit more detail. There are couple of presentations, one completely devoted to this topic and one that has a section on it. Both of them can be downloaded from slideshare.
