System Information Sending Method and Apparatus

A system information receiving apparatus, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• receive at least one of a synchronization signal of a serving cell or second indication information, wherein the second indication information indicates trigger signal sequence information;
• determine a trigger signal resource of the serving cell based on the synchronization signal or the second indication information, wherein the trigger signal resource of the serving cell comprises a time-frequency resource of at least one uplink trigger signal and/or sequence information of the at least one uplink trigger signal;
• generate an uplink trigger signal based on the trigger signal resource of the serving cell, and send the uplink trigger signal on a time-frequency resource of the uplink trigger signal;
• determine, based on the time-frequency resource of the uplink trigger signal, a second time-frequency resource group used for receiving system information;
• and
• receive the system information in the second time-frequency resource group of the system information.

A non-transitory computer-readable storage medium storing a program to be executed by a computer, the program including instructions that, when executed by the computer, cause the computer to:

• receive at least one of a synchronization signal of a serving cell or second indication information, wherein the second indication information indicates trigger signal sequence information;
• determine a trigger signal resource of the serving cell according to the synchronization signal or the second indication information, wherein the trigger signal resource of the serving cell comprises at least one of a time-frequency resource of at least one uplink trigger signal or sequence information of the at least one uplink trigger signal;
• generate an uplink trigger signal according to the trigger signal resource of the serving cell;
• send the uplink trigger signal on a time-frequency resource of the uplink trigger signal;
• determine, according to the time-frequency resource of the uplink trigger signal, a second time-frequency resource group used for receiving system information;
• and
• receive the system information in the second time-frequency resource group of the system information.
