Abstract

A method for transmitting system configuration information about uplink multiplexing of a 16m mobile station (MS) and a 16e MS is disclosed. The method comprises transmitting the system configuration information every super frame comprised of a plurality of radio frames. The system configuration information comprises an uplink configuration of time division multiplexing (TDM) and frequency division multiplexing (FDM) of the 16m MS and the 16m MS for each of the plurality of radio frames.

Claims

1. A method for transmitting system configuration information for a wireless mobile cellular communication system supporting uplink multiplexing of a first type mobile station (MS) and a second type mobile station (MS), the method comprising:

transmitting, at a base station of a cell, the system configuration information at a period of a time length of a first frame, the first frame comprised of a plurality of second frames,

wherein the system configuration information comprises an uplink configuration of time division multiplexing (TDM) and frequency division multiplexing (FDM) of the first type MS and the second type MS for each of the plurality of second frames.

2. The method of claim 1, wherein the time length of the first frame is 20 ms, and the first frame is comprised of four (4) of the second frames, each one of the second frames being 5 ms in time length.

3. The method of claim 1, wherein, the system configuration information further comprises a ratio of an amount of resources for the first type MS to an amount of resources for the second type MS for each one of the plurality of second frames.

4. The method of claim 3, wherein the ratio is set to a single fixed value for all of the second frames in the first frame.

5. The method of claim 4, wherein, the single value is independently set for each of the first frames.

6. The method of claim 3, wherein, the ratio is set to a first value for all second frames for FDM in the first frame, and

the ratio is set to a second value for all second frames for TDM in the first frame.

7. The method of claim 1, wherein the uplink configuration is represented by a bitmap format.

8. The method of claim 1, the system configuration information is represented in a table form.

9. The method of claim 1, wherein the system configuration information is transmitted at a period of a multiple of a time length of the first frame.

10. The method of claim 1, wherein the system configuration information is transmitted to a mobile station in a cell including the base station.

11. The method of claim 1, wherein the system configuration information is transmitted to a network entity of another cell.

12. The method of claim 1, wherein the system configuration information further comprises downlink-to-uplink resource ratio in the first frame, and the downlink-to-uplink resource ratio is represented by ceil(log 2(n1)) bits when the second frame is comprised of n1 number of third frames.

13. The method of claim 12, wherein, if the downlink-to-uplink resource ratio is given by x:

y, the uplink configuration of time division multiplexing (TDM) of the first type MS and the second type MS of a second frame is represented by ceil(log 2(n2*y/(x+y)) bits when the uplink area of the second frame is comprised of n2 number of third frames.

14. A method for transmitting system configuration information for a wireless mobile communication system supporting uplink multiplexing of a first type mobile station (MS) and a second type mobile station (MS), the method comprising:

transmitting, at a base station, the system configuration information at a period of a time length of a first frame,

wherein the system configuration information comprises an uplink configuration of time division multiplexing (TDM) and frequency division multiplexing (FDM) of the first type MS and the second type MS for the first frame, and the time length of the first frame is 5 ms.

15. The method of claim 14, wherein the system configuration information is written in UP-MAP field of the first frame.
