    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: In accordance with an example embodiment of the present invention, a method comprising: selecting, by a user equipment, a subset of linear combination coefficients from a linearized two-dimensional matrix having columns of frequency domain components and rows of spatial beams components for channel state information determination, wherein the number of linear combination coefficients in the subset is less than all of the linear combination coefficients; determining indication comprising information associated with column indices of the selected subset of linear combination coefficients from the linearized two-dimensional matrix, wherein the indication excludes the index of the column with lowest index of the linearized two-dimensional matrix; determining compressed channel state information comprising locations in the linearized two-dimensional matrix of the subset of linear combination coefficients and corresponding values of the linear combination coefficients at those locations; and reporting, from the user equipment toward the base station, the compressed channel state information.

    Abstract: A method for predicting channel state information is described. The method includes determining whether or not geodesic prediction is to be performed and transmitting the determination of whether or not geodesic prediction is to be performed in a first part of uplink control signaling. In response to determining that geodesic prediction is not to be performed, the method includes transmitting a current channel estimate in a second part of uplink control signaling, and in response to determining that geodesic prediction is to be performed, the method includes transmitting either a determined current value of a tangent vector, or a determined step size parameter, or both the determined current value of the tangent vector and the determined step size parameter in the second part of uplink control signaling. Channel state information is predicted based on information provided in the first and second parts of uplink control signaling.
