Abstract

The invention discloses a method, device and system for generating multi-carrier signals. In this method, filter configuration information corresponding to the subframe is determined according to attribute information of the subframe, the attribute information at least including any one of the following or a combination thereof: service type of the data signal, subframe information or channel information, The data signal includes a data signal carried in the subframe, and the subframe includes a plurality of symbols in the time domain; according to the filter configuration information, the filter corresponding to each filter configuration information is obtained. multi-carrier signal of the device group. In the multi-carrier multiplexing process, different filters are used for different services or different channels or different users, so as to meet the respective needs of different services or different channels or different users, and improve the efficiency of multi-carrier multiplexing.

Description

technical field [0001] The 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 frequency bands, in order to achieve higher data rates. [0003] Generally, filter bank multi-carrier (FBMC) is used to perform carrier multiplexing on data in a high-frequency band, that is, to increase the transmission rate by filters occupying a longer period on the time axis and symbols being overlapped 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 new types of equipment and business types in the 5G system, the signal generation of FBMC in the prior art is based on the same prototype filter. When informatio...
