Claim 5:
6. The method of claim 1, wherein:
determining the first estimated speed comprises at least one of:
estimating a speed of the WTRU relative to a fixed reference point using a global positioning system; and
estimating channel correlation with respect to reference signals received from the first transmission point at two time instances; and
determining the second estimated speed comprises at least one of:
estimating a channel coherence time using signal characteristics of a discovery reference signal;
determining a level of consistency between multiple reference-signal-received-power measurements of the second transmission point; and
using information obtained from a vehicle-to-vehicle message or a vehicle-to-infrastructure message received by the WTRU, wherein the information indicates at least one of an identification of a vehicle with which the second transmission point is associated, a speed of the vehicle, a direction of the vehicle, and location of the vehicle.
