Abstract

The application provides a data transmission method and device. The method includes the following steps: determining a data stream mapped to a data radio bearer (DRB); and controlling the transmissionrate of the data stream based on a transmission rate of the data stream and a first rate threshold of the data stream. According to the data transmission method and device provided by the application, the transmission rate of the data stream mapped to the DRB can be controlled.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a method and device for data transmission in the field of communication. Background technique [0002] In the long term evolution (LTE) system, the terminal equipment and the base station can carry user plane data through at least one data radio bearer (DRB), and the base station takes DRB as the granularity to prioritize logical channel configuration of the DRB. A bit rate (prioritized bit rate, PBR), so as to ensure that the transmission rate in each DRB can meet the guaranteed bit rate (guaranteed bit rate, GBR) of the base station. [0003] In the existing data transmission method, when configuring PBR for a DRB, the base station will refer to the GBR requirements of the DRB to ensure that the transmission rate in the DRB can meet the GBR requirements, that is, the existing data transmission is controlled based on DRB granularity. [0004] In the fifth generat...
