Abstract
Described are methods and apparatuses for providing channel state information by receiving configuration information for configuring a measurement window to form a compression matrix of a port selection codebook from a codebook set of vector components, the configuration information defining the size of the measurement window, which is common to all of at least one layer to be reported, selecting a number of indices of the measurement window based on the configuration information to form the compression matrix from the codebook set of vector components, remapping the selected indices, associated to vector components of the compression matrix, with respect to an index of a reference vector component, such that the index of the reference vector component is remapped to a first index of the measurement window, and reporting channel state information including precoding matrix indicator to a network, the precoding matrix indicator comprising information of the compression matrix after remapping.
