Abstract: There is provided a network element comprising means for defining one or more channel state information reporting configurations; means for determining, among the one or more channel state information reporting configurations, configurations for which a partial information update is allowable; and means for providing indication of the determined configurations to a user equipment. There is also provided a user equipment comprising means for determining which channel state information reporting configuration is applicable for a partial information update; means for examining whether a current channel state information reporting configuration is applicable for a partial information update; and means for, based on the examining, transmitting either a channel state information report containing providing a partial information update, when applicable, or transmitting a complete channel state information report, when not applicable.

Abstract: Example embodiments provide signaling and configuration for model-based channel state information reporting by an apparatus. Instead of reporting a table of indices or quantized values in case of a several hypotheses, coefficients of a model for requested channel state information may be reported. Apparatuses, methods, and computer programs are disclosed.

Abstract: There is provided a method at a network node of a communication network, comprising: receiving an uplink reference signal from a user equipment; estimating, based on the received uplink reference signal, delay information regarding a delay profile of a communication channel between the user equipment and the network node and spatial information regarding the communication channel; applying both the delay information and the spatial information in precoding of at least one downlink reference signal; transmitting the at least one precoded downlink reference signal to the user equipment; and receiving, from the user equipment as a response to the transmission of the at least one precoded downlink reference signal, channel information, the channel information indicating at least non-zero coefficients of at least one channel transmission layer.
