The present disclosure relates generally to wireless channel measurements, and more particularly to devices, non-transitory computer readable media, and methods for channel sounding using carrier aggregation.

BACKGROUND

The spatial, temporal and frequency characterization of the wireless channel in various environments is called “channel characterization.” The characterization provides a set of parameters which fully explain the medium's behavior in various scenarios. A wireless channel sounder is a device for measuring wireless channel related parameters such as complex impulse response, path loss, received signal strength (RSS), excess delay, or root-mean-square (RMS) delay spread, Doppler spread, fade rate, angle of arrival (AoA) and/or angle of departure (AoD), shadow fading, cross-polarization ratios, and the like as experienced by a user equipment or base station. In one implementation, a wireless channel sounder may utilize a directional antenna. For instance, to measure AoA using a directional antenna, the antenna may be turned in incremental steps to measure the RSS. The AoA is recorded where the RSS is at a maximum.

SUMMARY

In one example, the present disclosure discloses a method, computer-readable medium, and device for channel sounding using carrier aggregation. For example, a 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.
