An interesting CoMP architecture is the one associated with a distributed eNB depicted in Figure 7.8. Inthis particular illustration, the Radio Remote Units (RRU) of an eNB are located at different locations inspace. With this architecture, although the CoMP coordination is within a single eNB, the CoMPtransmission can behave like inter-site CoMP instead.Distributed eNBCell0Cell10Cell1RRU10FiberUE1RRU11FiberFibereNBCell11RRU12Cell12Cell2Figure 7.8. An Illustration of Intra-eNB CoMP with a Distributed eNB.7.8.4.3 DL COMPIn terms of downlink CoMP, two different approaches are under consideration: Coordinated scheduling, orCoordinated Beamforming (CBF), and Joint Processing/Joint Transmission (JP/JT). In the first category,the transmission to a single UE is transmitted from the serving cell, exactly as in the case of non-CoMPtransmission. However, the scheduling, including any Beamforming functionality, is dynamicallycoordinated between the cells in order to control and/or reduce the interference between differenttransmissions. In principle, the best serving set of users will be selected so that the transmitter beams areconstructed to reduce the interference to other neighboring users, while increasing the served user’ssignal strength.For JP/JT, the transmission to a single UE is simultaneously transmitted from multiple transmissionpoints, across cell sites. The multi-point transmissions will be coordinated as a single transmitter withantennas that are geographically separated. This scheme has the potential for higher performance,compared to coordination only in the scheduling, but comes at the expense of more stringent requirementon backhaul communication.Depending on the geographical separation of the antennas, the coordinated multi-point processingmethod (e.g. coherent or non-coherent), and the coordinated zone definition (e.g. cell-centric or usercentric),network MIMO and collaborative MIMO have been proposed for the evolution of LTE. Dependingon whether the same data to a UE is shared at different cell sites, collaborative MIMO includes single-cellantenna processing with multi-cell coordination, or multi-cell antenna processing. The first technique canbe implemented via precoding with interference nulling by exploiting the additional degrees of spatialwww.3GAmericas.org February 2010 Page 103
