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(shuō)明書(shū)

FIG. 15 schematically shows another relay transmission device 1400 according to an embodiment of the disclosure. The device 1400 includes a processor 1410 and a transceiver 1420.

The processor 1410 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 transceiver 1420 is configured to send the first layer-2 PDU generated by the processor 1410 to a relay terminal equipment.

Here, the device 1400 is the remote terminal equipment and the receiver equipment is a network equipment, or the device 1400 is the network equipment and the receiver equipment is the remote terminal equipment.

It is to be understood that the device 1400 may specifically be the sender equipment in the abovementioned embodiment and is configured to execute each step and/or flow corresponding to the sender equipment in the abovementioned method embodiment. Optionally, the device 1400 may further include a memory, and the memory may include a ROM and a RAM, and provides an instruction and data for the processor. A part of the memory may further include a nonvolatile RAM. For example, the memory may further store information about an equipment type. The processor may be configured to execute the instruction stored in the memory, and when the processor executes the instruction stored in the memory, the processor is configured to execute each step and/or flow of the abovementioned method embodiment.
