Transmission parameter configuration method and base station, information transmission method and terminal, and storage medium

An information transmission method, comprising:

• determining configuration of N basic transmission parameter sets, wherein the N basic transmission parameter sets comprise one or more parameters of a group consisting of:
• a time domain signal length, a sub-carrier number, a sub-carrier density, a sub-carrier spacing, a frequency domain guard band, a time domain guard time length, a cyclic prefix (CP) length, a number of Fast Fourier Transformation (FFT) points, and a baseband modulation mode;
• wherein N>1;
• selecting, according to reference information, a target basic transmission parameter set from the N basic transmission parameter sets, wherein the reference information comprises at least one of:
• a type of a channel or signal to be transmitted, blind-detected preamble sequence information, a bandwidth, and/or a number of transmission layers, and/or a number of antenna ports;
• and
• transmitting a channel or signal by adopting the selected target basic transmission parameter set,
• wherein the N basic transmission parameter sets correspond to N respective channel or signal sets, and
• wherein the method is performed by at least one processor.

A base station, comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor,
• wherein the processor is configured to:
• configure N basic transmission parameter sets, wherein the N basic transmission parameter sets comprise one or more parameters of a group consisting of:
• a time domain signal length, a sub-carrier number, a sub-carrier density, a sub-carrier spacing, a frequency domain guard band, a time domain guard time length, a cyclic prefix (CP) length, a number of Fast Fourier Transformation (FFT) points, and a baseband modulation mode;
• wherein N>1;
• and
• transmit M types of channels and/or signals by adopting the N basic transmission parameter sets, wherein N≤M,
• wherein the N basic transmission parameter sets correspond to N respective channel or signal sets;
• and
• wherein each of the N channel or signal sets comprises at least one of the M types of channels and/or signals.
