For multicell broadcast, soft combining of radio links should be supported, assuming a sufficient degree of inter-BS synchronization, at least between a subset of BSs. 2 Multihop Relay One important key to improve the coverage and capacity for high-quality multimedia broadcast and multicast transmissions in mobile networks is to provide a homogeneous service, regardless of the users’ positions, that is, to allow high data rates for UEs even at the cell edge. Moreover, the distribution of UEs inside the cell can be heterogeneous.

In this configuration, the nulling algorithm is implemented, at the transmitter side, using a preprocessing algorithm such as the ZF, MMSE, dirty paper coding, and so on. Alternatively, instead of implementing the above-described spatial multiplexing principle, the MU-MIMO can be performed using the beamforming algorithm. In any case, MU-MIMO requires accurate downlink CSI at the transmitter side. Obtaining CSI is trivial using TDD mode, being more difficult to be obtained when FDD is employed.

12 ◾ MIMO Processing for 4G and Beyond Antenna 1 ... 3 Generic block diagram of an open-loop transmitter scheme. relies on achieving higher symbol rates in a given bandwidth. This rate increase corresponds to the number of transmit antennas. Using multiple transmit and receive antennas, together with additional postprocessing, multilayer transmission allows exploiting multiple and different flows of data, increasing the throughput and the spectral efficiency. In this case, the number of receive antennas must be equal to or higher than the number of transmit antennas (although there is active research for underdetermined systems where that restriction is removed).
