Method and device for realizing data frame

Abstract

The embodiment of the present invention discloses a data frame implementation method and device, the method may include: configuring a data frame for wireless signal transmission, the data frame includes at least two subframes, each of which has a fixed length, The at least two subframes may be mapped to at least two frequency bands with different subcarrier spacings, and the number of symbols included in each subframe corresponds to the subcarrier spacing of the mapped frequency bands. The embodiment of the present invention can meet the diversified service requirements of 5G mobile communication, so as to improve the service level of 5G mobile communication.

Description

technical field [0001] The invention relates to the communication field, in particular to a data frame realization method and device. Background technique [0002] At present, with the development of communication technology and the increase of user demand, the industry is studying 5G mobile communication. Among them, 5G mobile communication needs to better meet the rapid development of future mobile Internet and Internet of Things services in addition to supporting traditional telecommunication services. develop. Therefore, the industry has put forward diverse business requirements for 5G mobile communications, including key performance requirements such as high capacity, short delay, large connection, high reliability, and high speed. Moreover, the requirements of diverse services for system numerical parameters are not uniform, or even mutually exclusive. For example, high-speed mobile users need wider subcarrier spacing to resist higher Doppler spread (Doppler Spread),...
