Network device, user equipment, and system information transmission method

An apparatus, comprising:

• a memory storing program instructions;
• and
• a processor coupled to the memory, wherein the program instructions, when executed by the processor, enable the apparatus to:
• determine, by means of downlink measurement, a coverage grade G_spec to which the apparatus belongs among N coverage grades {G_i|1≤i≤N} within a coverage area of a cell, wherein i is a positive integer, and N is an integer greater than 1;
• determine, according to a preset correspondence between the G_spec and a system information sending parameter of the cell, a target sending parameter corresponding to the G_spec;
• and
• receive, over a target channel in a receiving manner that matches the target sending parameter, a piece of system information S_spec sent by a network device serving the cell, wherein the target sending parameter is at least one of a physical-layer parameter and a higher-layer parameter that is used by the network device when apparatus belonging to the coverage grade G_spec within the cell is enabled to reliably receive the system information S_spec over the target channel.
