Channel sounding using carrier aggregation
First Claim
1. A method comprising:
- receiving, from a base station by a processing system of a channel sounding receiver including at least one processor, at a location, a channel sounding waveform via a plurality of carriers;
sampling, by the processing system, the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets;
processing, by the processing system, the plurality of per-carrier time domain sample sets via a plurality of discrete fourier transform modules, wherein the processing provides a plurality of per-carrier frequency domain sample sets;
aligning, by the processing system, the plurality of per-carrier frequency domain sample sets in gain and phase, wherein the aligning provides a combined frequency domain sample set; and
measuring, by the processing system, a channel property at the location based upon the combined frequency domain sample set.

Abstract
An example method may include a processing system of a channel sounding receiver having a processor receiving from a base station, at a location, a channel sounding waveform via a plurality of carriers, sampling the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets, and processing the plurality of per-carrier time domain sample sets via a plurality of discrete Fourier transform modules to provide a plurality of per-carrier frequency domain sample sets. The method may further include the processing system aligning the plurality of per-carrier frequency domain sample sets in gain and phase to provide a combined frequency domain sample set and measuring a channel property at the location based upon the combined frequency domain sample set.
