Abstract

The invention discloses a multi-carrier signal generating method, device and system. The method comprises the following steps of determining filter configuration information corresponding to a subframe according to attribute information of the subframe, wherein the attribute information at least comprises any one or a combination of the service type of a data signal and subframe information or channel information, the data signal comprises a data signal borne in the subframe, and the subframe comprises a plurality of symbols in a time domain; and acquiring a multi-carrier signal of a filter bank corresponding to each piece of filter configuration information according to each piece of filter configuration information. In a multi-carrier multiplexing process, different services or differentchannels or different users adopt different filters, so that the requirements of different services or different channels or different users are met, and the multi-carrier multiplexing efficiency isimproved.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a method, device and system for generating multi-carrier signals. Background technique [0002] With the development of wireless data services and fifth-generation mobile communication technology (5G), 5G systems need to have high frequencies, such as millimeter wave bands, in order to achieve higher data rates. [0003] Generally, filter bank multi-carrier (FBMC) is used to carry out carrier multiplexing for high-frequency band data, that is, the filter occupies a long period of time on the time axis and the symbols are overlapped to increase the transmission rate to reduce Out-of-band radiation, and keep the frequency band narrow, at the same time, can improve the spectral efficiency. [0004] However, for the newly added device types and service types in the 5G system, the signal generation of FBMC in the prior art is based on the same prototype filter. When the information...
