A12.1 OVERVIEW
The relative position between two points (ILT/ILR/VLT/VLR) is described by its Distance, Azimuth and Delta X,Y when an uncorrelated mode is selected or only by Delta X, Y when the correlated mode is selected. The selection of this mode and input parameters are described in Section 5.4.1 (VLT-VLR or ILT-ILR) and Section 10.3.1 (Interfering link to victim link path).
Within a generic system, the position of the receiver is always specified relative to the transmitter. For the relation between the interfering link and victim link, in a generic system the user may select the reference component as either the ILT or ILR, relative to either the VLT or VLR. This is illustrated below:

For a cellular system as victim or interferer the base station of the reference cell is always used to specify the relative positioning, as illustrated below:

The notation in this annex refers to positioning between a transmitter and receiver (Tx and Rx), but the same equations apply for any of the other positioning combinations outlined above.
