    Abstract: A system and method for detecting and selecting peaks in a delay power profile (DPP) signal. An adaptive threshold is used to determine valid paths in the DPP signal. The adaptive threshold is determined by measuring the signal-to-noise ratio of the DPP signal, and setting the threshold to minimize non-detections and false alarms in path estimation. To determine the signal-to-noise ratio, the system uses an iterative process wherein a raw estimate and an improved estimate are made of the noise.

    Abstract: A method of operating a wireless communication device or a radio access node comprises addressing multi-subcarrier system resources using at least one of multiple different numerologies available within a single carrier, wherein the multiple different numerologies comprise a first numerology having resource blocks with a first bandwidth and a first subcarrier spacing, ?f1, and a second numerology having RBs with a second bandwidth and a second subcarrier spacing, ?f2, which is different from ?f1, and wherein the first numerology is aligned in the frequency domain relative to a frequency reference, Fref, according to m*?f1 + Fref and the second numerology is aligned in the frequency domain relative to the frequency reference, Fref, according to n*?f2 + Fref, where m and n are integers. The method further comprises transmitting and/or receiving information within the single carrier according to the at least one of the multiple different numerologies.
