Wireless communication system, terminal device and base station for wireless communication system, and channel scheduling method thereof

A wireless communication system, comprising:

• a base station for controlling a wireless communication;
• and
• a terminal device connected to the base station to transmit and receive data,
• wherein the terminal device updates terminal state information representing a state thereof in a periodic or non-periodic manner and transmits the updated terminal state information to the base station, and the base station updates a data transmission schedule using the transmitted terminal state information and transmits data according to the updated schedule.

A method of scheduling channels of a wireless communication system, the method comprising the steps of:

• transmitting, by a terminal, terminal state information thereof to a base station;
• setting or updating, by the base station, channel scheduling mode according to the terminal state information and then transmitting the set or updated channel scheduling mode to the terminal;
• and
• transmitting and receiving data according to the set or updated channel scheduling mode.

A method of scheduling channels of a wireless communication terminal, the method comprising the steps of;

• transmitting a channel scheduling request message;
• receiving a response message to a channel scheduling request;
• transmitting terminal state information of the terminal device to a base station periodically or in response to a request of the base station;
• receiving channel scheduling mode updated by the base station according to the terminal state information;
• and
• receiving data according to the updated channel scheduling mode.

A method of scheduling channels of a wireless communication base station, the method comprising the steps of:

• (i) receiving a channel scheduling request message from a terminal;
• (ii) transmitting a response message to a channel scheduling request;
• (iii) receiving terminal state information of the terminal device from the terminal;
• (iv) updating channel scheduling mode according to the terminal state information and then transmitting the updated channel scheduling mode to the terminal;
• and
• (v) transmitting data according to the updated channel scheduling mode.
