Method, device, and system for notifying terminal type supported by current cell

A method for notifying a terminal of a terminal type supported by a current cell, comprising:

• receiving, by the terminal, a downlink signal from the current cell;
• and
• determining, by the terminal, according to preset indication information carried in the downlink signal, the terminal type supported by the current cell, wherein the preset indication information is a synchronization sequence or a first indicator bit used to indicate the terminal type supported by the current cell.

A base station, comprising:

• a processor, configured to generate a downlink signal that carries preset indication information, wherein the preset indication information indicates a terminal type supported by a current cell, and the preset indication information is a synchronization sequence or a first indicator bit used to indicate the terminal type supported by the current cell;
• and
• a sender, configured to send the downlink signal to the terminal.

A terminal, comprising:

• a receiver, configured to receive a downlink signal from a current cell;
• and
• a processor, configured to determine, according to preset indication information carried in the downlink signal, a terminal type supported by the current cell, wherein and the preset indication information is a synchronization sequence or a first indicator bit used to indicate the terminal type supported by the current cell.
