reporting
events for the
FDD mode1aA Primary CPICH enters the reporting rangeAddition a cell into active set.
1bA primary CPICH leaves the reporting rangeRemoval a cell from active set.
1cA non-active primary CPICH becomes better than an active primary CPICHReplacement of a cell within the active set.
1dChange of best cell in the active setChange the best cell.
1eA Primary CPICH becomes better than an absolute threshold
1fA Primary CPICH becomes worse than an absolute threshold
1jA non-active E-DCH but active DCH primary CPICH becomes better than an active E-DCH primary CPICH
Intrafrequency
reporting
events for the
TDD mode1gChange of best cell (TDD)Used in TDD Mode.
1hTimeslot ISCP below a certain threshold (TDD)Used in TDD Mode.
1iTimeslot ISCP above a certain threshold (TDD)Used in TDD Mode.
Interfrequency
reporting
events2aChange of best frequency
2bThe estimated quality of the currently used frequency is below a certain threshold and the estimated quality of a non-used frequency is above a certain threshold.Inter-frequency handover.
2cThe estimated quality of a non-used frequency is above a certain threshold
2dThe estimated quality of the currently used frequency is below a certain thresholdEnter compressed mode, start measuring neighbor cells on other frequencies (inter-frequency or inter-RAT) triggered by low DL signal.
2eThe estimated quality of a non-used frequency is below a certain threshold
2fThe estimated quality of the currently used frequency is above a certain thresholdLeave compressed mode.
Intersystem
reporting
events3aThe estimated quality of the currently used UTRAN frequency is below a certain threshold and the estimated quality of the other system is above a certain threshold.Inter-RAT handover.
3bThe estimated quality of other system is below a certain threshold
3cThe estimated quality of other system is above a certain threshold
3dChange of best cell in other system
Traffic-volume
reporting events4aTransport Channel Traffic Volume becomes larger than an absolute threshold
4bTransport Channel Traffic Volume becomes smaller than an absolute threshold
Quality
reporting events5aA predefined number of bad CRCs is exceeded
UE internal
measurement
reporting events6aThe UE Tx power becomes larger than an absolute thresholdEnter compressed mode, triggered by high UE power level.
6bThe UE Tx power becomes less than an absolute thresholdLeave compressed mode, triggered by resolution of 6a.
6cThe UE Tx power reaches its minimum value
6dThe UE Tx power reaches its maximum value
6eThe UE RSSI reaches the UE's dynamic receiver range
6fThe UE Rx-Tx time difference for a RL included in the active set becomes larger than an absolute thresholdFDD
6fThe time difference indicated by TADV becomes larger than an absolute threshold1.28 Mcps TDD
6gThe UE Rx-Tx time difference for a RL included in the active set becomes less than an absolute thresholdFDD
UE positioning
reporting events7aThe UE position changes more than an absolute threshold
7bSFN-SFN measurement changes more than an absolute threshold
7cGPS time and SFN time have drifted apart more than an absolute threshold
