RF fingerprinting map update

An apparatus and method in a communication system are disclosed. Data regarding an error between the location of the more than one user terminal and the estimated location of the more than one user terminal is obtained (500), the estimated location being obtained using radio frequency fingerprinting. It is assessed (502) whether the error is greater than a given threshold, and if so, it is determined (504) whether the error is due to radio frequency fingerprinting. Based on the determination, a decision (506) is made to initialize an update to the radio frequency fingerprinting map. 公开了通信系统中的装置和方法。关于多于一个用户终端的位置与所估计的多于一个用户终端的位置之间的误差的数据被获得(500)，所估计的位置利用射频指纹识别被获得。评估(502)该误差是否大于给定阈值，如果是，则确定(504)该误差是否由于射频指纹识别。基于该确定，决策(506)对射频指纹识别映射的初始化更新而被做出。
