Abstract

The embodiment of the invention discloses a data transmission method and equipment. The method comprises the following steps: a terminal sends uplink data in a grant-free mode; the terminal detects scheduling information in a target time window and generates a detection result, and the scheduling information is used for indicating configuration information of a data transmission channel; and the terminal determines whether to repeatedly send the uplink data according to the detection result. According to the embodiment of the invention, the data transmission delay is reduced, and the data transmission efficiency, intelligence and stability are improved.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2017 / 070486 with the filing date of January 06, 2017, which entered the Chinese national phase with the Chinese patent application number 201780078507.0, and the invention name is "a data transmission method and device". technical field [0002] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0003] A 4th Generation (4th Generation, 4G) mobile communication network, such as a Long Term Evolution (Long Term Evolution, LTE) network, has achieved wide coverage at present. 4G network is characterized by its fast communication speed, wide network spectrum, and flexible communication.
