Information transmission method and device

A method of transmitting information, the method comprising:

• determining, by a network device, that no remaining minimum system information (RMSI) is present;
• and
• sending, by the network device, a first synchronization signal block to a terminal device, wherein the first synchronization signal block comprises a first physical broadcast channel (PBCH), and information carried on the first PBCH comprises first information and second information;
• wherein the first information is used for indicating that RMSI is not present, the second information is used for indicating resource information of a second synchronization signal block, the second synchronization signal block comprises a second PBCH, information carried on the second PBCH comprises third information and fourth information, the third information indicates that RMSI is present, and the fourth information indicates a resource set carrying control information for receiving the RMSI.

An information transmission device comprising:

• a memory configured to store computer-executable instructions;
• one or more processors in communication with the memory and configured to execute the computer-executable instructions;
• and
• a communications interface configured to receive a first synchronization signal block sent by a network device, wherein the first synchronization signal block comprises a first physical broadcast channel (PBCH), and information carried on the first PBCH comprises first information and second information;
• wherein the one or more processors is configured to indicate, using the first information, whether remaining minimum system information (RMSI) is present, and when the first information indicates that RMSI is not present, the one or more processors is configured to indicate, using the second information, resource information of a second synchronization signal block, and
• wherein the communications interface is further configured to receive the second synchronization signal block according to the resource information of the second synchronization signal block, wherein the second synchronization signal block comprises a second PBCH, information carried on the second PBCH comprises third information and fourth information, the third information indicates that RMSI exists, and the fourth information indicates a resource set carrying control information for receiving the RMSI.

An information transmission device comprising:

• a memory configured to store computer-executable instructions;
• one or more processors in communication with the memory and configured to execute the computer-executable instructions to at least determine that no remaining minimum system information (RMSI) exists;
• and
• a communications interface configured to send a first synchronization signal block to a terminal device, wherein the first synchronization signal block comprises a first physical broadcast channel (PBCH), information carried on the first PBCH comprises first information and second information, the first information is used to indicate that no RMSI exists, and the second information is used to indicate resource information of a second synchronization signal block, wherein the second synchronization signal block comprises a second physical broadcast channel PBCH, information carried on the second PBCH comprises third information and fourth information, the third information indicates that RMSI exists, and the fourth information indicates a resource set carrying control information for receiving the RMSI.
