Abstract
The present invention provides a method and a device for selecting user terminal so as to enhance calibration for reciprocity error between uplink and downlink, in the purpose of enhancing the accuracy of calibration for reciprocity error between uplink and downlink in TDD system. Wherein, the method comprises the following steps: obtaining channel quality related information between a plurality of first user terminals and a first base station, wherein said channel quality related information is used for indicating channel qualities between said plurality of first user terminals and said first base station; selecting, at least one first user terminal as a calibration user terminal for calibrating said reciprocity error between uplink and downlink, according to said channel quality related information.
