Abstract: An apparatus comprising circuitry configured to: receive a plurality of signal samples, wherein at least two of the signal samples are received on different carrier frequencies or over different durations; convert the plurality of signal samples to a common data format that stores as entries the samples, a stored entry corresponding to a sample measured with a carrier frequency, a time, and a receive antenna; generate entries of the common data format that are missing due to a sample not being measured with a carrier frequency, time, and receive antenna; wherein the entries of the common data format are ranked, wherein a higher ranking entry is considered more relevant than a relatively lower ranking entry; and generate at least one positioning measurement with a machine learning model, based on the entries of the common data format and the ranking of the entries of the common data format.

Abstract: A device for reconstructing a channel state information (C) and a method of reconstructing a channel state information, wherein the device for reconstructing includes circuitry for reconstructing the channel state information depending (C) on a first encoding (Tm) of the channel state information (C) understandable by a first decoder, and determining the first encoding (Tm) depending on a second encoding (W1, . . . , WM) of the channel state information (C) understandable by a second decoder. A device for encoding a channel state information and a method of encoding a channel state information, wherein the device for encoding includes circuitry for determining a first encoding of the channel state information understandable by an encoder, determining a second encoding of the channel state information understandable by a decoder depending on the first encoding.

Abstract: An apparatus configured to: transmit, to at least one UE, an indication of a measurement reporting scheme; transmit, to the at least one UE, at least one RS on at least one first beam; receive, from the at least one UE, a set of RSRP measurements of one or more of the at least one RS, according to the measurement reporting scheme; and provide the set of RSRP measurements to a machine learning model for prediction of best beams from a second set of beams. An apparatus configured to: receive, from a network node, an indication of a measurement reporting scheme; measure at least one RS on at least one first beam; generate a set of RSRP measurements of one or more of the at least one reference signal based, at least partially, on the measurement reporting scheme; and transmit, to the network node, the set of RSRP measurements.
