... including scheduling, feedback, and dealing with mobility. Two-way relaying requires research for interference mitigation in the uplink. Finally, combining base station coordination and relaying ... as shown in Figure 2. For shared relaying and base station coordination, the interfering sectors share the same frequency. For the one-way relay and the two- way relay, the in...

... standpoint in their origi- nal domains. An integra l transform maps an equation from its original domain (time or space domain) into another domain (frequency domain). Manipulating and solving ... the equation in the target domain is, ideally, easier than ma- nipulating and solving it in the original domain. The solu- tion is then mapped back into the original domain. Integral trans...
