Abstract: There is provided an apparatus, said apparatus comprising means for receiving a multiple input multiple output signal from a network, determining a frequency domain basis subset for each layer of the multiple input multiple output signal, determining from the frequency domain basis subset a number, MC, of frequency domain components common to each layer, determining, from the frequency domain basis subset, a number of layer-specific frequency domain components and providing to the network, in uplink control information, an indication of the frequency domain components common to each layer and the layer-specific frequency domain components.

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.
