A multi-carrier signal generation method, comprising:
- determining, according to attribute information of a subframe, filter configuration information corresponding to the subframe, wherein the attribute information comprises any one of the following or a combination of more than one of the following:
- a service type, subframe information, and channel information of a data signal;
- wherein the data signal comprises a data signal carried on the subframe, and the service type comprises a delay requirement;
- and
- acquiring, according to each of the filter configuration information, a multi-carrier signal of filter bank corresponding to each of the filter configuration information,
- wherein determining, according to attribute information of a subframe, filter configuration information corresponding to the subframe comprises any one of the following or a combination of more than one of the following:
- determining, according to a subcarrier spacing of the subframe, a filter corresponding to the subframe;
- determining, according to a delay requirement of the data signal carried by the subframe, a filter corresponding to the subframe;
- determining, according to a delay requirement of the data signal carried by the subframe, a time domain extension of a filter corresponding to the subframe;
- determining, according to subframe position information of the subframe, a filter corresponding to the subframe adjacent to an uplink and downlink switching point to be a filter with a small time domain expansion;
- and
- determining, according to subframe position information of the subframe, a time domain extension of a filter corresponding to the subframe adjacent to an uplink and downlink switching point to be consistent with edge of the subframe.
