Abstract: The application relates to a user equipment for wireless communications with a multiple-input multiple-output (MIMO) base station over a wireless communications channel. The user equipment comprises a communications interface configured to receive a current pilot signal over the wireless communications channel from the base station, and at least one processor configured to determine a current channel state information (CSI) based on the current pilot signal and to determine a CSI reliability measure value based on the current CSI and one or several previous CSI, where the at least one processor is configured to determine the previous CSI based on previous pilot signals, i.e. previously received pilot signals.

Abstract: A network entity comprises a plurality of antenna elements arranged in one or more two dimensional (2D) arrays having one or more columns and rows. The network entity configured to determine at least one set of one or more precoding vectors related to the plurality of antenna elements, wherein each set of precoding vectors is associated with a different Kronecker product tradeoff parameter L≥1; and transmit, at least one set of a plurality of Cell Specific Reference Signals (CRS) to be used to estimate channel state information (CSI) based on the at least one set of precoding vectors and/or at least one Kronecker product tradeoff parameter L.
