Abstract: When sensing is performed in a radio access network, clutter may be removed from echo signals using clutter contributing signals, that may be determined based on clutter calibration matrices and one-dimensional echo signals obtained by transforming multi-dimensional representations of echo signals at least partly into the one-dimensional echo signals. When generating, for example, clutter calibration matrices, sensing results may be transformed into one dimensional vectors, that are arranged to two-dimensional matrices. Vectors associated with clutter components in two-dimensional matrices may be used to obtain the clutter calibration matrices.

Abstract: An apparatus, comprising at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause the apparatus at least to determine a set of position estimates for a mobile device, wherein each position estimate of the set of position estimates is associated with a) a specific one of a plurality of K many receiver devices configured to receive a reference signal from the mobile device or b) a specific one of a plurality of K many transmitter devices configured to transmit reference signals to the mobile device, and to determine, based at least on the set of position estimates, a set of residual errors associated with at least some position estimates of the set of position estimates.
