Abstract: A wireless communication method for a terminal, a terminal, and a wireless communication system receive one or more Channel State Information Reference Signals (CSI-RSs). Further, quantization of combination coefficients of the one or more CSI-RSs corresponding to one or more spatial beams Discrete Fourier Transform (DFT) basis vector amplitudes is performed.
Abstract: A method of aperiodic signal transmission from a base station (BS) to a user equipment (UE) includes transmitting, from the BS to the UE, reservation information indicating first resources reserved for aperiodic signal transmission via higher layer signaling, transmitting, from the BS to the UE, Downlink Control Information (DCI) indicating at least a second resource to be selected based on the first resources, and transmitting, from the BS to the UE, the aperiodic signals using the first resources.

Abstract: A method of Channel State Information Reference Signal (CSI-RS) transmission from a base station (BS) to a user equipment (UE) includes reserving, with the BS, a CSI-RS resource used for aperiodic CSI-RS transmission in subframes transmitted from the BS, transmitting, from the BS to the UE, reservation information indicating the CSI-RS resource via higher layer signaling, and transmitting, from the BS to the UE, the aperiodic CSI-RS using the CSI-RS resource.
