1. A method for predicting timing advance (TA) with respect to a base station, the method comprising:
determining, by a user equipment (UE), a set of TAs, each TA corresponding to a particular distance from the base station;
receiving, by the UE from the base station, one or more signals;
measuring, by the UE, a set of instances of a power metric, each instance of the power metric associated with a respective distance from the base station, the measuring based at least in part on the one or more signals;
determining, by the UE, a set of differences between each of the instances of the power metric; and
determining, by the UE, a new TA at least in part using the set of TAs and the set of differences.
