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 configuration information of the EPS bearer includes MAC-layer configuration information and PHY-layer configuration information. In such case, the sending unit 930 is further configured to send a connection establishment response to the remote terminal equipment, the connection establishment response containing the PHY-layer configuration information and the MAC-layer configuration information.

In an optional example, the device 900 may specifically be the relay terminal equipment in the abovementioned embodiment, and the device 90Q may be configured to execute each flow and/or step corresponding to the relay terminal equipment in the abovementioned method embodiment and will not be elaborated herein to avoid repetitions.

FIG. 12 schematically shows another relay transmission device 1100 according to an embodiment of the disclosure. The device 1100 includes a processing unit 1110 and a sending unit 1120.

The processing unit 1110 is configured to perform encapsulation processing on data to be sent to a receiver equipment to generate a first layer-2 PDU. Here, the first layer-2 PDU contains identification information of a remote terminal equipment, or the first layer-2 PDU is scheduled through a PDCCH scrambled by adopting an RNTI of the remote terminal equipment.

The sending unit 1120 is configured to send the first layer-2 PDU generated by the processing unit 1110 to a relay terminal equipment.

Here, the device 1100 is the remote terminal equipment and the receiver equipment is a network equipment, or the device 1100 is the network equipment and the receiver equipment is the remote terminal equipment.
