Handover Measurements in LTE
Measurements to be performed by a UE for intra/inter-frequency mobility are controlled by e-UTRAN, using broadcast or dedicated control.
If the frequency center of the measured cell is the same
- No measurement gaps are required
- If the frequency center of the measured cell is not the same
- Measurement gaps are required
In RRC_CONNECTED state, a UE shall follow the measurement configurations specified by RRC directed from
the e-UTRAN (e.g. as in UTRAN MEASUREMENT_CONTROL).
