RELAY NODE COMMUNICATION SCHEME USING TRANSMISSION INDICATOR

摘要

PURPOSE: A relay device communication technique using a transmission indicator is provided to flexibly use resources by combination with a method of using allocated resources. CONSTITUTION: An RN(Relay Node) transmits a negative response to a transmission indicator of DeNB(Donor evolved-NodeB) to DeNB(S402). When the RN transmits a positive response to the transmission indicator to DeNB, the DeNB transmits data to the RN through a PDSCH(Physical Downlink Shared Channel) of Un(S403). When signal transmission is predicted through DL Uu at a time corresponding to the transmission indicator or the signal transmission can not stopped, the RN transmits a signal to UE(User Equipment) through DL Uu(S404~S406).
