Problems solved by technology

For example, in the same bit error rate scenario, when bit errors do not occur on average in BL data and EL data, when bit errors occur less in BL data, the recovery effect of video data will be significantly enhanced, Because the decoding error of BL data not only makes the BL data unrecoverable, but also affects the correctly received EL data
However, in the transmission mechanism of downlink user plane data on the side of the evolved NodeB (eNB) in the existing LTE access network, each transmission time interval (Transmission Time Interval, TTI) is multiplexed and generated containing the same video The processing of Media Access Control (Media Access Control, MAC) Protocol Data Unit (Protocol Data Unit, PDU) of data in different layers of the service adopts equal error protection (Equal Error Protection, EEP) at the physical layer, which will cause the same video service The probability of bit errors in different layers of data in the data is the same, and stronger error protection cannot be given to BL data under the same network conditions, which will reduce the end-to-end transmission quality of the video

Abstract

A data processing method, a base station and a terminal device.A data processing method comprises:a base station performing channel coding on a first CB so as to obtain a third CB, wherein the third CB includes:first system information, first-path check information and second-path check information;the base station performing channel coding on a second CB so as to obtain a fourth CB, wherein the fourth CB includes:second system information, third-path check information and fourth-path check information, and an importance degree of data borne by the third CB is higher than that of data borne by the fourth CB;the base station multiplying a pre-set coding matrix and the first system information to generate check information about a linear block code;the base station performing exclusive-or calculation on the check information about the linear block code and the second system information so as to obtain third system information, and replacing the second system information included in the fourth CB with the third system information so as to obtain a fifth CB; and the base station sending the third CB to a terminal device, and the base station sending the fifth CB to the terminal device.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data processing method, a base station, and a terminal device. Background technique [0002] In recent years, mobile terminals have become more and more intelligent, with rich types and continuously improved terminal performance. The functions and services supported by mobile terminals have become more and more abundant. The rate reaches 100 Mbits per second (Million bits per second, Mbps), which can provide users with a better mobile Internet experience, and the resulting mobile data traffic also shows explosive growth. [0003] Compared with other services in mobile terminals, video services are developing rapidly, and video services have a relatively high bit rate feature. Video traffic will become the main data source of mobile networks in the future. [0004] The original video data sequence needs to be compressed and coded before network transmiss...
