Abstract

An embodiment of the present application provides a method and device for transmitting data, the method comprising: a first device sends first data to a second device using a first transmission method, and the first data is data sent autonomously by the first device; The first device uses a second transmission mode to retransmit all or part of the first data, and the first transmission mode is different from the second transmission mode. The method for transmitting data in the embodiment of the present application can improve transmission reliability during retransmission.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to a method and device for transmitting data. Background technique [0002] In the 5G system, a grant-free uplink data transmission method is introduced, and terminal devices can independently initiate uplink data transmission without scheduling signaling from network devices. However, the transmission method used by the terminal equipment to transmit data may not match the current uplink channel, so it is difficult to achieve a large transmission gain, resulting in low transmission reliability. Therefore, a method is needed to improve the transmission reliability. Contents of the invention [0003] Embodiments of the present application provide a data transmission method and device, which can improve transmission reliability during retransmission. [0004] In a first aspect, a method for transmitting data is provided, including: a first device sends first data t...
