Method and arrangement for CSI measurement
There are proposed a base station and User Equipment, UE, for determining and applying separate Channel State Information, CSI, for flexible subframes in a wireless communication system applying time division duplex, TDD. The method in a UE comprises, for a flexible subframe, receiving (103) a signal from a base station, and determining (104) whether a reference signal for CSI measurement is comprised in the received signal. The method further comprises determining (106) CSI for the flexible sub-frame based on the reference signal when a reference signal for CSI measurement is comprised in the received signal, and reporting (107) the determined CSI to the base station.
