Abstract

The invention discloses a method and device for relay transmission, which can reduce the complexity and time delay of data processing. The method includes: a relay terminal device receives the first layer-2 PDU sent by a sender device to a receiver device, wherein, The first Layer 2 PDU carries the identification information of the remote terminal equipment, or the first Layer 2 PDU is scheduled through the PDCCH scrambled by using the RNTI of the remote terminal equipment; the relay terminal equipment according to the first two Layer PDU, generating a second Layer 2 PDU; the relay terminal device sends the second Layer 2 PDU to the receiving end device; wherein, the sending end device is the remote terminal device and the receiving end device is a network device, or The sending end device is a network device and the receiving end device is the remote terminal device.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for relay transmission. Background technique [0002] Device-to-Device (D2D) technology means that adjacent terminal devices can transmit data through direct links within a short distance without forwarding through network devices. D2D communication can share licensed frequency band resources with the cellular system to form a unified hybrid cellular-D2D network. In this hybrid network, some terminal devices can still work in cellular communication mode, that is, communicate with other terminal devices through network devices, while some terminal devices can work in D2D communication mode, that is, through direct links with other terminal devices Direct data transfer with other end devices. [0003] In addition, the data transmission between the network device and the terminal device can be assisted by the D2D relay. At this time,...
