摘要

Disclosed in the present invention are a relay transmission method and device, enabling reduction of complexity and latency of data processing. The method comprises: a relay terminal apparatus receives a first layer-two PDU sent by a transmitting-end apparatus to a receiving-end apparatus, wherein the first layer-two PDU carries identifier information of a remote terminal apparatus, or the first layer-two PDU schedules a scrambled PDCCH by means of an RNTI of the remote terminal apparatus; the relay terminal apparatus generates, according to the first layer-two PDU, a second layer-two PDU; and the relay terminal apparatus sends to the receiving-end apparatus the second layer-two PDU, wherein the transmitting-end apparatus is the remote terminal apparatus, and the receiving-end apparatus is a network apparatus; alternatively, the transmitting-end apparatus is a network apparatus, and the receiving-end apparatus is the remote terminal apparatus.

Optionally, before relay transmission, the network equipment may further establish an EPS bearer for the remote terminal equipment. Here, the EPS bearer may include a data transmission channel (for example, a GTP tunnel) between the network equipment and the P-GW and a radio bearer established by the network equipment. Here, the radio bearer may include 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. However, the embodiment of the disclosure is not limited thereto.

Optionally, the relay terminal equipment may 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. Optionally, the connection establishment request may specifically be a direct communication request configured to request for establishment of a PC5 connection with the relay terminal equipment.
