Information transmission method, device, base station and computer readable storage medium

An information transmission apparatus, comprising:

• a memory, a processor and a computer program stored in the memory and executable by the processor, wherein the processor, when executing the computer program, implements:
• determining at least one of a time domain position, a frequency domain position or a spatial domain position for transmitting information, wherein the information comprises a signal and/or a channel;
• and
• performing transmission of the information at the determined at least one of the time domain position, the frequency domain position or the spatial domain position for transmitting the information;
• wherein enabling an SS/PBCH block to satisfy a requirement for an occupied channel bandwidth in an unlicensed spectrum in frequency domain comprises at least one of:
• transmitting the SS/PBCH block as a whole for multiple times;
• transmitting the SS/PBCH block as a whole alternately with remaining minimum system information (RMSI) in the frequency domain;
• transmitting the SS/PBCH block as a whole and RMSI respectively for multiple times in the frequency domain;
• multiplexing and transmitting the SS/PBCH block and a downlink channel/signal in a manner of frequency division multiplexing (FDM);
• or
• transmitting the SS/PBCH block in the frequency domain by using a resource element (RE)-level resource allocation mode;
• and
• wherein the RE-level resource allocation mode of the SS/PBCH block comprises one of:
• assuming that a bandwidth is B1 and corresponds to B2 resource blocks (RBs) and B2*12 subcarriers, dividing the B2*12 subcarriers into P1 clusters, wherein each cluster comprises B2*12/P1 subcarriers, each of the P1 clusters comprises 240/P1 SS/PBCH block positions, and the SS/PBCH block is mapped at a position having a corresponding number in each of the P1 cluster.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores one or more programs, and the one or more programs are executable by one or more processors to implement:

• determining at least one of a time domain position, a frequency domain position or a spatial domain position for transmitting information, wherein the information comprises a signal and/or a channel;
• and
• performing transmission of the information at the determined at least one of the time domain position, the frequency domain position or the spatial domain position for transmitting the information;
• wherein enabling an SS/PBCH block to satisfy a requirement for an occupied channel bandwidth in an unlicensed spectrum in frequency domain comprises at least one of:
• transmitting the SS/PBCH block as a whole for multiple times;
• transmitting the SS/PBCH block as a whole alternately with remaining minimum system information (RMSI) in the frequency domain;
• transmitting the SS/PBCH block as a whole and RMSI respectively for multiple times in the frequency domain;
• multiplexing and transmitting the SS/PBCH block and a downlink channel/signal in a manner of frequency division multiplexing (FDM);
• or
• transmitting the SS/PBCH block in the frequency domain by using a resource element (RE)-level resource allocation mode;
• and
• wherein the RE-level resource allocation mode of the SS/PBCH block comprises one of:
• assuming that a bandwidth is B1 and corresponds to B2 resource blocks (RBs) and B2*12 subcarriers, dividing the B2*12 subcarriers into P1 clusters, wherein each cluster comprises B2*12/P1 subcarriers, each of the P1 clusters comprises 240/P1 SS/PBCH block positions, and the SS/PBCH block is mapped at a position having a corresponding number in each of the P1 cluster.
