Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for Uplink Control Information (UCI) design. The method comprises determining, at a terminal device, a matrix comprising a set of non-zero linear combination coefficients for quantizing a channel between the terminal device and a network device, the matrix having spatial components and frequency components; shifting the frequency components of the matrix circularly, such that a target coefficient of the set of non-zero linear combination coefficients is located in a frequency component with a predetermined index of the frequency components in a shifted matrix; generating a first indication indicating the spatial component associated with the target coefficient in the matrix; and transmitting, to the network device, uplink control information comprising the first indication. In this way, a new solution for designing the UCI may reduce the overhead for reporting the parameters in the UCI.

Abstract: An UL channel for a UE is measured based on reference signal (s) to determine UL channel information. DL channel information is inferred based on UL-DL channel reciprocity and the determined UL channel information. Reporting is configured based on the inferred DL channel information for CSI for the UE and resource (s) are allocated for the UE to use to report the CSI. Information is signaled to the UE indicating a configuration of the reporting of CSI and the resource (s). DL reference signal (s) are transmitted toward the UE to be used for determination of the CSI. Report (s) of CSI are received on the allocated resource (s). The UE receives the configuration, determines the CSI using the configuration and the received DL reference signal (s) and fits the determined CSI into the allocated resource (s). The UE transmits the determined CSI on the allocated resource (s).
