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.

說明書

Optionally, the second layer-2 PDU may contain the identification information of the remote terminal equipment, for example, the terminal equipment identifier or the layer-2 identifier.

Specifically, when the sender equipment is the remote terminal equipment and the receiver equipment is the network equipment, the first layer-2 PDU may optionally contain the terminal equipment identifier of the remote terminal equipment. In such case, the relay terminal equipment may determine the layer-2 identifier corresponding to the terminal equipment identifier, and the layer-2 identifier is contained in the second layer-2 PDU. The network equipment may determine the remote terminal equipment corresponding to the second layer-2 PDU according to the layer-2 identifier, contained in the second layer-2 PDU, of the remote terminal equipment and send the data contained in the second layer-2 PDU to core network equipment (for example, a P-GW).
