l capacity needs to be improved in general. Because the closed loop spatial multiplexing mode of MIMO works on the feedback mechanism (Precoding Matrix Index [PMI] feedback) provided by the UE to the network, it is important that the UE is not fast moving and is either stationary or very slow moving for best results. The urban small office model and dense urban model are two main deployment types where the cell can be configured for transmission mode 4 (TM4) (closed loop spatial multiplexing). Open Loop Spatial Multiplexing Open loop spatial multiplexing, like closed loop spatial multiplexing, is also targeted to improve the cell or sector throughput for a particular area of deployment. However, open loop spatial multiplexing does not rely on the PMI reporting from the UE but works on a predefined set of precoding selection for spatial multiplexing. More often, the cyclic delay diversity (CDD) technique is used for open loop spatial multiplexing. In CDD, the transmitting unit adds cyclic time shifts and creates multipath transmission. The eNodeB tries to ensure that the transmission happens on the resource blocks for which the UE has reported better channel quality indicator (CQI) value. By doing this, the UE is able to receive the original stream as well as the delayed stream of data, and the delay on the transmit side ensures that there is no signal cancellation on the receiver side. This is more useful for areas where the UE moves at a higher speed or the channel conditions change faster, for example, TM3 (open loop spatial multiplexing) can be set for cells that are modeled for highway deployment, which has many fast moving users. Beamforming Beamforming is a MIMO technique wherein the eNodeB transmitter tries to improve the quality of the signal that is received by specific users. This can be done by adjusting the tilt and power of the transmitter in the direction of the UE. Implementing beamforming can be very complicated, wherein the UE positioning has to be determined and the UE specific reference signals
