Title: METHOD AND APPARATUS FOR TWO-HOP PACKET TRANSMISSION
Abstract:
Embodiments of the present disclosure provide a method and device for two-hop packet transmission. The method implemented at a relay device for two-hop packet transmission comprises: at a radio link control (RLC) sub-layer of a radio link layer (L2): obtaining status information of second hop RLC transmission of the two-hop packet transmission; and transmitting the status information to a transmitting device in first hop RLC transmission of the two-hop packet transmission for the transmitting device to control the first hop RLC transmission based on the status information. According to the embodiments of the present disclosure, an effective solution for L2 relay performed at an RLC sub-layer can be provided.
