Reply To: Femtocells: FFR setting


Hi Naser,

the results-calculation for “low RB occupancy” is not valid when using FFR, since the RB_occupancy information from the scheduler does not fit (RBs for the different re-use parts are all occupied but are averaged over all FFR parts and therefore not correct – this will have to be adjusted).

As I wrote earlier: when simulating FFR for your specified values (only macros), I see an improvement in the results. For combining femto-cells and FFR, this does not have to be the case, since there are overlapping areas of frequency re-use from femtos and macros. Since the gain of FFR comes from the better spatial separation, this might destroy any performance gain, when using het-nets.

Best regards,
