All measurement events are described in 3GPP TS 25.331
INTRA-FREQUENCY EVENTS
Event 1a
A Primary CPICH enters the Reporting Range (FDD only).
Event 1b
A Primary CPICH leaves the Reporting Range (FDD only).
Event 1c
A Non-active Primary CPICH becomes better than an active Primary CPICH (FDD only).
Event 1d
Change of best cell (FDD only).
Event 1e
A Primary CPICH becomes better than an absolute threshold (FDD only).
Event 1f
A Primary CPICH becomes worse than an absolute threshold (FDD only).
INTER-FREQUENCY EVENTS
