METHOD, DEVICE AND SYSTEM FOR DATA TRANSMITTING

摘要

The invention discloses a method, device and system for data transmitting. Ingress Station packages or fragments the Service Data Units (SDUs) transmitted using the same Tunnel, encapsulates them into Relay Medium Access Control Packet Data Unit (MAC PDU) and sends the Relay MAC PDU to Egress Station, wherein the Relay MAC PDU includes a Tunnel-Connection Identifier (T-CID). The device includes package unpacking module, classification mapping module and ability negotiating module. The system includes base stations and relay stations. The invention reduces a number of packages of information in the data transfer process and saves system resources.
