Method and device for allocating a broadcast channel in a wireless mobile communication system
A method for receiving a superframe header at a mobile station in a wireless mobile communication system is disclosed. The method comprises receiving a sub-frame including the superframe header and a first data channel and decoding the received superframe header. Herein, the superframe header is located within a predetermined physical frequency band and the predetermined physical frequency band includes a synchronization channel.
1. A method for transmitting a superframe header to mobile stations in a wireless mobile communication system, the method comprising:
transmitting a sub-frame including the superframe header and a first data channel,
wherein the superframe header is located within a predetermined physical frequency band, and
wherein index numbers of logical resource units allocated to the superframe header are continuous in value and starting from the lowest logical index number of the total system bandwidth or the frequency partition that contains the superframe header.
2. The method of claim 1 , wherein the superframe header is composed of a primary superframe header and a secondary superframe header.
3. The method of claim 2 , wherein index numbers of logical resource units allocated to the primary superframe header are continuous in value, which starts from the lowest logical index number of the total system bandwidth or the frequency partition that contains the superframe header, and index numbers of logical resource units allocated to the secondary superframe header are continuous in value.
4. The method of claim 3 , wherein a maximum value of the index numbers of the logical resource units allocated to the primary superframe header is less than a minimum value of the index numbers of the logical resource units allocated to the secondary superframe header by 1.
5. The method of claim 3 , wherein a minimum value of the index numbers of the logical resource units allocated to the primary superframe header is 0 (zero).
6. The method of claim 2 , wherein the primary superframe header comprises resource allocation information for the secondary superframe header and resource allocation information for the first data channel.
7. The method of claim 2 , wherein the secondary superframe header comprises resource allocation information for a second data channel included in another sub-frame which follows the received sub-frame and do not include a superframe header.
8. The method of claim 2 , the superframe header includes resource allocation information for another sub-frame which includes a superframe header and succeeds the received sub-frame.
9. The method of claim 1 , wherein a permutation rule applied for the superframe header is independent from a permutation rule applied for the first data channel.
10. The method of claim 1 , wherein a permutation rule applied for the superframe header is independent from a permutation rule applied for a second data channel included in another sub-frame which follows the received sub-frame and do not include a superframe header.
11. A method for receiving a superframe header at a mobile station in a wireless mobile communication system, the method comprising:
receiving a sub-frame including the superframe header and a first data channel,
wherein a maximum granularity of a permutation for the superframe header is one resource unit, and
wherein a permutation rule applied for the superframe header is the same as a permutation rule applied for the first data channel.
12. The method of claim 11 , wherein resources for the superframe header are allocated only with distributed logical resource units.
13. The method of claim 11 , wherein the permutation rule applied for the superframe header is the same as a permutation rule applied for a second data channel included in another sub-frame which follows the received sub-frame and do not include a superframe header.
