Provided are a quality prediction method and device for a physical downlink control channel of a long term evolution system. In the method, a target user equipment (UE) requiring physical downlink control channel (PDCCH) quality prediction is determined, and information reported by the target UE is received. According to the reported information, a prediction index of the target UE is determined, wherein the prediction index is a signal to interference plus noise ratio (SINR) of the control channel or an equivalent reception level (RPp DCCH ) of the control channel. According to the SINR or the RP PDCCH , the PDCCH quality of the target UE is determined. The present invention can be applied to provide more accurate and highly efficient control channel quality prediction for LTE users without adding measurement and signalling, thereby achieving the purpose of providing a quick and precise positioning basis for a control channel element (CCE) resource and power allocation algorithm of an Evolved Node B (eNodeB). |
