Problems solved by technology

In the fifth generation (5thgeneration, 5G) large connection system, in order to improve the transmission efficiency of data between terminal devices, network coding technology has begun to be used in the data transmission of the physical layer, and the network coding of the physical layer is realized through the air interface channel. Indirect data transmission can be realized between two terminal devices through relay node forwarding. After the relay node receives the data, it first performs network coding, and then sends the network coded data. However, the current method is due to the Network coding will take a certain amount of time, so the data transmission efficiency is low

Embodiment Construction

[0061] As used in this application, the terms "component," "module," "system" and the like are intended to refer to a computer-related entity, which may be hardware, firmware, a combination of hardware and software, software, or an operating system. software. 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. As an example, 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 media having various data structures thereon. These components can be communicated through, for example, based on having one or more packets of data (e.g., data from a component that...

Abstract

The invention discloses a network coding method and device, and relates to the field of communication. The network coding method comprises that: first terminal equipment determines first indication information, wherein the first indication information is used for indicating whether to pre-process a phase of first to-be-coded data to be sent by the first terminal equipment; carrying out data transmission between a first terminal equipment and a second terminal equipment through an electromagnetic metasurface array antenna in the same time slot of the same transmission resource, comprising the following steps: the first terminal equipment sends third to-be-coded data to the electromagnetic metasurface array antenna in a first time slot of a second transmission resource, and first network coding data is received from the electromagnetic metasurface array antenna at a first time slot, wherein the third to-be-coded data is obtained according to the first indication information and the first to-be-coded data; and enabling the first terminal equipment to obtain second to-be-coded data from the second terminal equipment according to the third to-be-coded data and the first network coding data.

Description

technical field [0001] The present application relates to the communication field, in particular to a network coding method and device. Background technique [0002] Network coding (network coding, NC) technology is an information exchange technology that combines routing and coding. Through network coding, the maximum flow of routing transmission can be achieved, and the efficiency of data transmission is improved. In the fifth generation (5thgeneration, 5G) large connection system, in order to improve the transmission efficiency of data between terminal devices, network coding technology has begun to be used in the data transmission of the physical layer, and the network coding of the physical layer is realized through the air interface channel. Indirect data transmission can be realized between two terminal devices through relay node forwarding. After the relay node receives the data, it first performs network coding, and then sends the network coded data. However, the cu...
