Abstract: Systems, methods, apparatuses, and computer program products for non-linear precoding are provided. One method may include combining, by a network node, of linear and non-linear precoding, for example based on specific channel state information acquisition from at least one user equipment, and generating two types of demodulation reference signals for the concatenated linear and non-linear precoding. The method may include multiplexing, by the network node, the two types of demodulation reference signals with data. A first of the two types of demodulation reference signals may be linearly precoded with one linear precoding matrix from a first-stage linear precoder, and another one of the two types may be linearly precoded with both the first-stage linear precoder and a feedforward filter in a second-stage non-linear precoder from the concatenation of linear and nonlinear precoders.

Abstract: A method for implementing co-polarized feedback for frequency domain compression is disclosed. The method includes feeding back compressed channel state information, wherein at least one layer is restricted to be transmitted on one polarization and the feedback for the at least one layer only involves the channel state information on the one polarization.

Abstract: This document discloses a method and an apparatus to perform using a predicted sequence of beam measurement outputs for at least one observation window associated with at least one prediction window providing reference signal received power measurements to predict a beam prediction output; identifying that a prediction window of the at least one prediction window is overlapped with at least a portion of an observation window of the at least one observation window over a time period; and comparing the beam prediction output during the overlapped portion with measurements of the observation window during the overlapped portion to perform long term real time monitoring to determine at least one prediction output for use in a next time instant, wherein the determining is based on a predicted reference signal received power of the at least one prediction output being above a threshold.

Abstract: Systems, methods, apparatuses, and computer program products for reporting of feasibility of activated transmission configuration indicator/transmission coordination indication (TCI) states. For example, a user equipment (UE) may determine whether one or more measurements satisfy one or more thresholds for one or more TCI states, and may transmit an indication of whether the one or more measurements satisfy the one or more thresholds. The UE may then deactivate at least one of the one or more activated TCI states, or may activate one or more additional TCI states, based on the indication, and may use one or more of the activated TCI states for a downlink (DL) or uplink (UL) transmission.
