[WCDMA] RRC Measurement

[3GPP TS 25.331]

The different types of measurements are:
- Intra-frequency measurements: measurements on downlink physical channels at the same frequency as the active set. A measurement object corresponds to one cell.
- Inter-frequency measurements: measurements on downlink physical channels at frequencies that differ from the frequency of the active set and on downlink physical channels in the active set. A measurement object corresponds to one cell.
- Inter-RAT measurements: measurements on downlink physical channels belonging to another radio access technology than UTRAN, e.g. GSM. A measurement object corresponds to one cell.
- Traffic volume measurements: measurements on uplink traffic volume. A measurement object corresponds to one cell.
- Quality measurements: Measurements of downlink quality parameters, e.g. downlink transport block error rate.
A measurement object corresponds to one transport channel in case of BLER. A measurement object
corresponds to one timeslot in case of SIR (TDD only).
- UE-internal measurements: Measurements of UE transmission power and UE received signal level.
- UE positioning measurements: Measurements of UE position.
