Abstract
A system and a method for a mobility measurement in a wireless network comprises determining at a wireless terminal a channel power estimation ES for a carrier signal based on Channel State Information Reference Signals (CSI-RS), and determining at the wireless terminal a noise plus interference I+N for the carrier signal based on a muted CSI-RS. The carrier signal is an additional carrier without the presence of a Cell-specific Reference Signal. In one exemplary embodiment, the periodicity of the CSI-RS is selected to be 1, 2 or 3 subframes.
