Abstract

A method and an arrangement (800) in a user equipment (420) for reporting Channel State Information, CSI, and a method and an arrangement (1000) in a base station (410) for obtaining CSI are provided. The user equipment (420) is in connection with the base station (410) in a cellular communication network (400). After receiving a receiving (702) a grant in a subframe n to be used for CSI reporting, from the base station, the user equipment determines (703) subfiame type of a subframe n+p. The user equipment then reports (704) to the base station, CSI reflecting channel conditions in the subfiame type of subfiame n+p. p is a variable value.
