Method of avoiding interference to device-to-device (D2D) communications caused by cellular communications in honeycomb and D2D hybrid network

A method of avoiding interference to device-to-device (D2D) communications caused by cellular communications in a honeycomb and D2D hybrid network includes that according to interference information reported by D2D user equipment (EU) and historical information dispatched by uplink stored by a base station, after the base station distinguishes cellular user equipment (CeUE) of a cellular user which causes harmful interference to a particular D2D UE, the base station provides radio network temporary identifier (RNTI) causing the interference to the D2D UE and related information for the disturbed D2D UE to assist the D2D UE to decode CeUE information causing the interference to the D2D UE. By using the method, the D2D UE is capable of forecasting disturbed condition of the CeUE in a corresponding transmission time interval (TTI) and performing a corresponding radio resource management operation to avoid the harmful interference to the subsequent D2D mode communications caused by the CeUE. Through the assist of the base station, operation of calculating and decoding of a physical downlink control channel (PDCCH) by the D2D UE is simple, flexible and convenient and workable in a long term evolution (LTE) / LTE-A system.
