Abstract: Methods and apparatuses are provided in which frequency domain (FD) interpolation is performed on wideband reference signal (RS) resource elements (REs) to generate channel estimates on corresponding RS symbols. Denoising may be performed on the channel estimates in a time domain (TD) or a delay-Doppler domain (DD). Learning-based channel estimation (LCE) is applied on the channel estimates using a neural network (NN) to generate refined channel estimates on the corresponding RS symbols. Time domain (TD) interpolation is performed on the refined channel estimates to produce a channel estimate across symbols.

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 and a method are disclosed for decoding in wireless communications. In some embodiments, a method includes receiving a reference signal; generating a channel estimate, based on the reference signal; determining a channel estimation error metric for the channel estimate; receiving a transmission; calculating a log likelihood ratio, based on the channel estimation error metric, for each of a plurality of bit positions of the transmission; and decoding the transmission based on the log likelihood ratio. The calculating of the log likelihood ratio may include calculating a corrected log likelihood ratio based at least on an uncorrected log likelihood ratio.

Abstract: A system and a method are disclosed for performing beam tracking using a GNN. A method of beam prediction by a UE includes receiving an input feature vector; comparing the input feature vector to a lookup table of rated predicted beams; selecting a corresponding predicted beam having a highest rating from the lookup table; and receiving, from a base station, a signal using the selected predicted beam.
