Abstract: This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.
