Abstract: Systems, methods, apparatuses, and computer program products for non-linear precoding in radio access networks are provided. One method may include, when it is determined that a user equipment is capable of being non-linearly precoded, determining one of two non-linear precoding modes and indicating the determined non-linear precoding mode to the user equipment. One of the two non-linear precoding modes is configured to use explicit beamformed channel state information, and the other one of the two non-linear precoding modes is configured to use explicit full downlink channel state information.

Abstract: Embodiments of the present disclosure provide a communication method and device for uplink power control. The method comprises receiving a plurality of sets of power control parameters from a network device, each of the plurality of sets being associated with a corresponding one of a plurality of sets of candidate beam patterns for the terminal device. The method further comprises selecting, based on a beam pattern for the terminal device, one of the plurality of sets of power control parameters for uplink transmit power control, the beam pattern for the terminal device being included in the set of candidate beam pattern that is associated with the selected set of power control parameters.
