Abstract

An embodiment of the invention discloses a data transmission method and a base station, which are used to solve the collision problem in the data transmission process under the condition of coexistence of scenes of different processing delays. The method comprises the following steps: the base station receives quality of service (QoS) parameters of at least one service, wherein the QoS parameters comprises any one or the combination of more than two of time delay sensitiveness, reranking indication parameters, RTT indication parameters or TTI indication parameters, the time delay sensitiveness being used for indicating different delay requirements of various data in the at least one service, the reranking indication parameters being used for indicating whether the order of the data in the at least one service needs rescheduling; and the base station carries out configuration on wireless bearing according to the QoS parameters and transmits the data according to the wireless bearing obtained after configuration.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and a base station. Background technique [0002] In the current long-term evolution (LTE, Long Term Evolution), LTE-A (LTE, Long Term Evolution-Advanced) and other advanced long-term evolution systems, some parameters are used to characterize the service quality (QoS, Quality of Service) requirements of the business, such as: delay , packet loss rate, business processing priority, etc. The wireless network transmits and processes relevant data according to the values ​​of these parameters. [0003] Latency is a key performance indicator for measuring communication system performance and affecting user experience. Therefore, how to reduce data transmission delay is a goal of continuous attention and optimization of communication systems. [0004] In the current LTE and LTE-A systems, a radio frame structure of 10 ms and a subframe of 1 ms are designe...
