Spatio-Temporal Propagation Modeling 19 proposals discussed in 3GPP (see technical documents for spatial channel model). This section describes in greater detail the parametric stochastic model that has been adopted recently by the 3GPP. The combined 3GPP-3GPP2 spatial channel model ad-hoc group has specified parameters and methods for spatial channel modeling. The scope is the development of specifications for system-level evaluation with emphasis on the physical parameters, and link-level evaluation, defined only for calibration purposes (not for evaluation or comparisons).

Considering the assumption of CSI at the transmitter, we can proceed to the following capacity formula. 15 is the coefficient Lk that corresponds to the amount of power that is assigned to the kth subchannel. 16) and satisfies the constraint ¨ n k =1 L k = nt . 15. 5 Channel Estimation at the Transmitter As mentioned earlier, the CSI is not usually available at the transmitter. In order for the transmitter to obtain the CSI, two basic methods are used: the first is based on feedback and the second on the reciprocity principle.
