1. A communications node of a multi-node communications network, comprising:
a communications interface including at least one antenna element; and
a controller operatively coupled to the communications interface, the controller including one or more processors;
wherein a common reference frame of the communications network is known to the controller;
and
wherein the controller is configured to:
receive, via the communications interface, at least one of a preamble or a header portion associated with a resource allocation message transmitted by a transmitting (Tx) node of the communications network, the Tx node in motion according to a velocity vector comprising a velocity and a direction;
determine a receiver (Rx) nulling direction by adjusting a receiving frequency of at least one of the preamble or the header portion through at least one nulling frequency corresponding to a nulling direction, the Rx nulling direction configured to correct a Doppler frequency shift associated with the velocity vector;
and
determine, based on the adjusting, one or more of:
the velocity of the velocity vector of the Tx node;
the direction of the velocity vector of the Tx node;
or
a direction of the Tx node relative to the communications node.
