Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable me...

Abstract

The invention provides a data transmission method and device. The method comprises the following steps: access network equipment determines transmission modes of service data, wherein the transmissionmodes comprise a single transmission mode and the transmission mode for automatic retransmission; the access network equipment sends first indication information to terminal equipment, and the firstindication information is used for indicating the determined transmission mode; and the access network equipment sends the service data to the terminal equipment by adopting the determined transmission mode. Through the data transmission method and device provided by the invention, the requirements on the reliability and the flexible delay can be satisfied.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method and device for data transmission.
