Problems solved by technology

However, in practical applications, for high-quality data transmission with strict bit error rate requirements, the high-quality data transmission cannot be guaranteed by using long-code error-correcting codes at the physical layer. The reason is that if the information receiving device judges The received data needs to be retransmitted. In the process of feedback signaling from the information receiving device to the information sending device, it needs to go through multi-hop RS; after the information receiving device receives the feedback signaling, it retransmits the data packet, and the retransmitted The transmission of data packets from the information receiving device to the information sending device also needs to go through multi-hop RS. Therefore, the retransmitted data information not only increases the overhead of system resources, but also easily causes a large transmission delay, thereby reducing the quality of signal transmission. , cannot meet the high QoS requirements of the system

Abstract

The invention discloses a method, a device and a system for processing information. The method comprises the following steps: receiving the data to be sent by layers above a physical layer of an information sending device, using short-code long error correcting codes to carry out error correction coding, and encapsulating the data into code blocks comprising data blocks and check blocks; carryingout cyclic redundancy check (CRC) coding on the encapsulated code blocks by the layers above the physical layer, adding packet head information on the code blocks which are processed by CRC coding, encapsulating into protocol data unit (PDU) data packets, and sending the data packets to the physical layer; after the physical layer receives the PDU data packets, carrying out physical layer coding;and modulating and sending the PDU data packets after physical layer coding. Because the process of short-code long error correcting code coding for the transmitted data information is added for the layers above the physical layer, the reliability and the quality of the data transmission are improved, the probability that the data needs to be retransmitted is reduced, the processing of the systemfor the retransmitted data is reduced, and the resources and the cost of the system are saved.

Description

technical field [0001] The invention relates to wireless communication information processing technology, in particular to an information processing method, device and system. Background technique [0002] In the evolved LTE-Advanced system of the 3GPP Long Term Evolved standard (LTE, Long Term Evolved) and the IMT-Advanced system of the International Mobile Telecommunications (IMT, International Mobile Telecommunications), in order to improve the information transmission environment, improve the information sending equipment and the information receiving equipment To improve the signal transmission quality, reduce the packet loss rate, and ensure the reliability of information transmission, the relay technology is introduced. That is, a relay station (RS, Relay Station) is introduced between the information sending device and the information receiving device to relay the data information sent by the information sending device, so that the information sending device, informa...
