Abstract: A method and an apparatus for providing reference signal received power (RSRP) are disclosed herein. A signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements at the RS locations are descrambled. Virtual reference signal (VRS) elements are formed using the descrambled signal elements. The VRS elements have smaller noise variances than original RS elements in corresponding locations of the received signal. The RSRP is estimated from the VRS elements.

Abstract: A method of channel estimation for a precoded channel includes generating an initial frequency autocorrelation of the precoded channel for a current bundle of a received data transmission, generating an expanded frequency autocorrelation based on the initial frequency autocorrelation of the precoded channel, providing the expanded frequency autocorrelation to a neural network, generating, by the neural network, an estimated frequency autocorrelation of an unprecoded channel based on the expanded frequency autocorrelation, and generating an estimated power distribution profile of the unprecoded channel based on the estimated frequency autocorrelation.

Abstract: A method and an apparatus for providing reference signal received power (RSRP) are disclosed herein. According to one embodiment, a signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements are descrambled to remove a RS sequence. A linear average of the descrambled signal elements is performed to form virtual reference signal (VRS) elements. The RSRP is estimated from the VRS elements.

Abstract: A system includes: a first transmitter to transmit a first signal; a second transmitter to transmit a second signal; a receiver to receive a downlink signal, the downlink signal including a desired signal and an interference signal corresponding to the first and second signals; a processor; and memory including instructions that, when executed by the processor, cause the processor to: select an interference function based on center frequencies of the first and second transmitters and the receiver; calculate correlation values based on a first delay between the receiver and a reference transmitter, and a second delay between the first and second transmitters; select one or more filter taps based on the calculated correlation values; estimate the interference signal based on the selected one or more filter taps and the interference function; determine the desired signal from the downlink signal according to the estimated interference signal; and transmit the desired signal.

Abstract: A method includes predicting, using the at least one processing device, a question type for each section of a document using a trained question type prediction model, each section including a different portion of the document. The method also includes generating, using the at least one processing device, multiple question-answer pairs using a trained question-answer generation model that receives the predicted question types and the document as input. Each question-answer pair includes (i) a question having a type corresponding to one of the predicted question types and being associated with content in the section corresponding to the type and (ii) an answer to the question. The method further includes outputting, using the at least one processing device, the question-answer pairs for use in training a question answering model.
