Doppler clustering techniques for per cluster parameter estimation and cluster detection

A method of wireless communication performed by a first network entity, comprising:

• receiving a plurality of signals via a plurality of channels, wherein each signal of the plurality of signals comprises a same payload, and wherein a plurality of Doppler shifts is associated with the plurality of signals;
• determining, based on a plurality of phase channel responses associated with the plurality of signals, two or more clusters of signals from the plurality of signals, wherein each signal of the plurality of signals is associated with a respective phase channel response of the plurality of phase channel responses based on a respective Doppler shift;
• and
• detecting, based on the two or more clusters, one or more communication conditions.

An apparatus for wireless communication, comprising:

• means for receiving a plurality of signals via a plurality of channels, wherein each signal of the plurality of signals comprises a same payload, and wherein a plurality of Doppler shifts is associated with the plurality of signals;
• means for determining, based on a plurality of phase channel responses associated with the plurality of signals, two or more clusters of signals from the plurality of signals, wherein each signal of the plurality of signals is associated with a respective phase channel response of the plurality of phase channel responses based on a respective Doppler shift;
• and
• means for detecting, based on the two or more clusters, one or more communication conditions.

A non-transitory computer-readable medium having code for wireless communication stored thereon that, when executed by a network node, causes the network node to:

• receive a plurality of signals via a plurality of channels, wherein each signal of the plurality of signals comprises a same payload, and wherein a plurality of Doppler shifts is associated with the plurality of signals;
• determine, based on a plurality of phase channel responses associated with the plurality of signals, two or more clusters of signals from the plurality of signals, wherein each signal of the plurality of signals is associated with a respective phase channel response of the plurality of phase channel responses based on a respective Doppler shift;
• and
• detect, based on the two or more clusters, one or more communication conditions.
