說明書
Optionally, when the sender equipment is the network equipment and the receiver equipment is the remote terminal equipment, the first layer-2 PDU is scheduled by the network equipment through a PDCCH scrambled by a relay-specific RNTI. In such case, the processing unit 920 is further configured to, before generating the second layer-2 PDU according to the first layer-2 PDU, determine that the data contained in the first layer-2 PDU is required to be forwarded according to the relay-specific RNTI adopted for the PDCCH configured to schedule the first layer-2 PDU.
Optionally, the receiving unit 910 is further configured to, before receiving the first layer-2 PDU sent by the sender equipment, receive a connection establishment request of the remote terminal equipment. The connection establishment request is configured to request for establishment of a D2D communication link between the relay terminal equipment and the remote terminal equipment; the sending unit 930 is further configured to send a bearer establishment request to core network equipment in response to the connection establishment request, the bearer establishment request containing the terminal equipment identifier of the remote terminal equipment to enable the core network equipment to establish an EPS bearer of the remote terminal equipment with the network equipment; and the receiving unit 910 is further configured to receive a bearer establishment response sent by the network equipment, the bearer establishment response containing configuration information of the EPS bearer established for the remote terminal equipment by the network equipment. Here, the EPS bearer includes a cellular data transmission channel between the network equipment and the relay terminal equipment and a D2D data transmission channel between the relay terminal equipment and the remote terminal equipment.
