Abstract: Systems, methods, apparatuses, and computer program products for detecting mismatch in digital twin data. One method may include receiving, by a radio network control system, at least one of reliability and latency constraint communication related values from one or more sources with geolocation information. The method may further include comparing the at least one of received reliability and latency constraint communication related values to one or more threshold values of the one or more sources to determine presence of a mismatch. The method may also include sending one or more indications of the comparison of the at least one of reliability and latency constraint communication related values and the one or more threshold values to a system element for determining a need for one or more actions.

Abstract: Example embodiments of the present disclosure relate to channel state based beamforming enhancement. A first device receives, from a second device, a second message indicating a second channel state. The second message has a second length less than a first length of a first message indicating a first channel state previously received from the second device. The first device obtains combined beamforming features of the second device according to a trained combining model associated with the second device and based on the second message and historical beamforming features of the second device. The first device generates a beam weight for the second device according to a trained beamforming model and based on the combined beamforming features. The first device may generate a beam weight for the second device according to the beamforming model without recovering CSI from the message.

Abstract: Radio receiver devices and related methods and computer programs are disclosed. A radio signal including information bits is received at a radio receiver device. The radio receiver device determines log-likelihood ratios, LLRs, of the information bits. The determining of the LLRs is performed by applying an iterative neural network, NN, to a frequency domain representation of the received radio signal over a transmission time interval, TTI. The iterative NN includes a single processing block iteratively executable to process the frequency domain representation of the received radio signal. The iterative NN is configured to output estimates of the LLRs based on the processing results of the single processing block.

Abstract: According to an example embodiment, a radio transmitter includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the radio transmitter to obtain bits to be transmitted; map the bits into a symbol grid in time-frequency domain; modulate the symbol grid into a first time-domain waveform; input the first time-domain waveform into a machine learning model, producing a second time-domain waveform; power amplify the second time-domain waveform, producing an amplified time-domain waveform; and transmit the amplified time-domain waveform. A radio transmitter, a method and a computer program product are disclosed.
