Abstract: Systems, methods, apparatuses, and computer program products for transmitter residual carrier frequency offset compensation. The method may include receiving, at a reference user equipment, configuration for a positioning reference measurement from a network element. The method may also include estimating a transmission carrier frequency offset of the network element based on the positioning reference measurements. The method may further include transmitting the estimated transmission carrier frequency offset in a report to the network element.
