METHOD AND DEVICE FOR SELECTING USER TERMINAL SO AS TO ENHANCE RECIPROCITY ERROR CALIBRATION BETWEEN UPLINK AND DOWNLINK

摘要

The present invention provides selection method and device, user terminal is to enhance the error between calibration reciprocity uplink and downlink, in order to mention high-precision calibrate for the reciprocity error between uplink and downlink in a tdd system. Wherein this method comprises the following steps: obtaining the channel quality relevant information between multiple first user terminals and first base station, whereinThe relevant information of the channel quality be used to indicate the first user between the multiple channel quality terminal and the initial corner station; Selection, at least one first user terminal is used to calibrate the error between the reciprocity uplink and downlink as calibration user terminal, according to the channel quality relevant information.
