Is there any functional difference between intra-lte and inter-RAT measurements performed by an UE ?

Question

Since both the events B1 and B2 are used for Inter RAT measurement reporting. Which one is chosen by eNodeB and on what basis ? Is there any dependency on UE capability for that ?

Answer 1

There is a functional difference when UE performs intra frequency measurements or inter frequency/IRAT measurements and UE is capable only to receive one transmission at a time.

Suppose eNB has configured the intra freq measurements for UE then there is no need to enable measurements gaps for that UE.

Suppose eNB has configured the intra, inter and IRAT measurement to UE then eNB will enable the measurement gaps for inter freq and IRAT measurement. For inter freq/IRAT measurement UE needs to switch from serving freq to the inter/IRAT frequency.
