Abstract

A method of transmitting and receiving channel bandwidth information in a wireless communication system is disclosed, by which backward compatibility can be maintained. The present invention includes transmitting the channel bandwidth information including information on a maximum number of resource blocks available for a mobile station supporting the first system and transmitting information on a number of resource blocks available for a mobile station supporting the second system.

Claims

1. A method of transmitting channel bandwidth information, which is transmitted by a base station in a wireless communication system supporting a first system and a second system, the method comprising the steps of:

transmitting the channel bandwidth information including information on a maximum number of resource blocks available for a mobile station supporting the first system; and

transmitting information on a number of resource blocks available for a mobile station supporting the second system.

2. The method of claim 1, wherein the information on the number of the resource blocks available for the second system supporting mobile station comprises the information on the resource blocks available for the second system supporting mobile station in addition to the resource blocks available for the first system supporting mobile station.

3. The method of claim 2, the step of transmitting the information on the number of the resource blocks available for the second system supporting mobile station, comprising the steps of:

adding a field to a system information block (hereinafter abbreviated SIB) carried on a physical downlink shared channel (hereinafter abbreviated PDSCH); and

transmitting the information on the number of the resource blocks available for the second system supporting mobile station via the added field.

4. The method of claim 2, the step of transmitting the information on the number of the resource blocks available for the second system supporting mobile station, comprising the steps of:

adding a field to a master information block (hereinafter abbreviated MIB) carried on a physical broadcast channel (hereinafter abbreviated PBCH); and

transmitting the information on the number of the resource blocks available for the second system supporting mobile station via the added field.

5. The method of claim 1, wherein in the information on the number of the resource blocks available for the second system supporting mobile station, the number of the resource blocks available for the second system supporting mobile station is represented as an index.

6. A method of receiving channel bandwidth information, which is received by a mobile station in a wireless communication system supporting a first system and a second system, the method comprising the steps of:

receiving the channel bandwidth information including information on a maximum number of resource blocks available for a mobile station supporting the first system; and

transmitting information on a number of resource blocks available for a mobile station supporting the second system.

7. The method of claim 6, wherein the information on the number of the resource blocks available for the second system supporting mobile station comprises the information on the resource blocks available for the second system supporting mobile station in addition to the resource blocks available for the first system supporting mobile station.

8. The method of claim 7, further comprising the steps of:

obtaining a number of resource blocks available for the mobile station using the information on the maximum number of the resource blocks available for the mobile station supporting the first system and the information on the number of the resource blocks available for the mobile station supporting the second system; and

transceiving data with the base station using the resource blocks corresponding to the obtained number of the resource blocks.

9. The method of claim 7, the step of receiving the information on the number of the resource blocks available for the second system supporting mobile station, comprising the step of receiving the information on the number of the resource blocks available for the second system supporting mobile station via a system information block (hereinafter abbreviated SIB) carried on a physical downlink shared channel (hereinafter abbreviated PDSCH).

10. The method of claim 7, the step of receiving the information on the number of the resource blocks available for the second system supporting mobile station, comprising the step of receiving the information on the number of the resource blocks available for the second system supporting mobile station via a master information block (hereinafter abbreviated MIB) carried on a physical broadcast channel (hereinafter abbreviated PBCH).

11. A base station in a wireless communication system supporting a first system and a second system, comprising:

a processor generating information on a maximum number of resource blocks available for a mobile station supporting the first system and information on a number of resource blocks available for a mobile station supporting the second system; and

a transmitting module transmitting the information on the maximum number of the resource blocks available for the mobile station supporting the first system and the information on the number of the resource blocks available for the mobile station supporting the second system.

12. The base station of claim 11, wherein the information on the number of the resource blocks available for the second system supporting mobile station comprises the information on the resource blocks available for the second system supporting mobile station in addition to the resource blocks available for the first system supporting mobile station.

13. A mobile station in a wireless communication system supporting a first system and a second system, comprising:

a receiving module receiving information on a maximum number of resource blocks available for a mobile station supporting the first system and information on a number of resource blocks available for a mobile station supporting the second system; and

a processor obtaining a number of resource blocks available for the mobile station using the information on the maximum number of the resource blocks available for the mobile station supporting the first system and the information on the number of the resource blocks available for the mobile station supporting the second system.

14. The mobile station of claim 13, further comprising a transmitting module transmitting data to a base station using the resource blocks corresponding to the obtained number of the resource blocks.
