Abstract

This technology relates to a communication device and a communication method which make it possible to implement highly reliable and low-delay communication. Provided is a communication device which is a base station and is equipped with a control unit which performs control for generating redundancy information relating to redundancy of transmission data to be transmitted by a terminal station orthe base station, and multiplexing information relating to multiplexing of the transmission data, and transmitting the generated redundancy information and multiplexing information to the terminal station. This technology is applicable, for example, to a wireless LAN system.

Description

technical field [0001] The present technology relates to a communication device and a communication method, and particularly to a communication device and a communication method that can realize communication with high reliability and low delay. Background technique [0002] In recent years, for ultra-high-quality image transmission such as virtual reality (VR) and augmented reality (AR), remote operation of precision machines, etc., it is required to improve the reliability of wireless communication. In addition, low latency is required for applications such as ultra-high-quality image transmission such as VR and AR, remote operation of precision machines, and the like. [0003] For example, Patent Document 1 discloses a technique for simultaneously transmitting the same Protocol Data Unit (PDU) through multiple channels to improve the robustness of the system.
