Abstract
A disclosed computer-implemented method may include receiving, as part of a demodulation reference signal (DMRS) channel estimation operation, a frequency-domain channel estimation signal that includes a sequence of DMRS channels. The method may also include generating an augmented DMRS channel sequence that may include generating (1) based on an edge DMRS channel and an additional DMRS channel included in the sequence of DMRS channels, an extended DMRS channel sequence that includes a plurality of extended DMRS channels that extend a frequency range of the sequence of DMRS channels, and (2) based on an interpolation matrix and the extended DMRS channel sequence, an extrapolated DMRS channel sequence that includes extrapolated DMRS channels that further extend the frequency range of the sequence of DMRS channels. The method may also include interpolating a data channel based on the augmented DMRS channel sequence. Various other methods and systems are also disclosed.
