TheWI addresses thresholds for the coordination of CDMA and LTE broadband systemsin the 400 MHz band.
The scenarios will involve:
- LTE systems on bothsides of a border;
- An LTE system on oneside of the border and a CDMA system on the other side.
ECC Report 108 already describes the situation of 2 systems CDMA vs CDMA.
In particular, PCI code coordination for LTE systems is considered as an option to allow for the relaxation of threshold values (with the same centre frequencies or overlapping frequency use, preferential or non-preferential PCI codes).
