Abstract: The present disclosure provides a method for establishing a relay connection in a device to device (D2D) broadcast communication-based relay network, which includes as follows. Relay node user equipment (RNUE) transmits a relay broadcast (RBC) message based on indicator of a Donor evolved Node B (DeNB), provides necessary information for selecting a relay node (RN) to a user UE (UU). Furthermore, the RNUE detects a relay request (RRQ) message coming from the UU in corresponding resources. For an accepted RRQ, the RNUE confirms the relay connection with a corresponding UU by using a relay response (RRP) message. Based on the received RBC message, standard definition, or pre-configuration, the UU may determine transmission resources of the RRQ message, so as to establish a connection with the RNUE. By using the method provided by the present disclosure, relay connection between the RNUE and UU may be established at the cost of smaller standard change.
