1. A method to perform adjacent channel leakage ratio (ACLR) measurements in a cellular network, the method comprising:
receiving transmission of a symbol from a base station in an allocated frequency band;
creating a measurement timing for the transmitted symbol;
measuring transmitted power levels in the allocated frequency band based on the created measurement timing;
measuring power levels in adjacent bands based on the created measurement timing; and
deriving ACLR from the measured transmitted power levels in the allocated frequency band and the measured power levels in the adjacent bands.
