Correct.
Intra-frequency neighbour (cell) measurements are performed by the UE when the current and target cell operates on the same carrier frequency. The UE should be able to carry out such measurements without measurement gaps.
For Intra-frequency neighbouring cells, there is no need to indicate neighbouring cell in the serving cell system information to enable the UE to search and measure a cell i.e. E-UTRAN relies on the UE to detect the neighbouring cells. Where as for the search and measurement of inter-frequency neighbouring cells, only the carrier frequencies need to be indicated.
The UE is required to detect an E-UTRA FDD or TDD intra-frequency target cell within 800 ms
