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, at a base station, 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 the system configuration information in a super frame header at a first period, the first period comprised of a plurality of super frames, the super frame comprised of a plurality of frames,

wherein the system configuration information comprises a configuration index used for indicating whether time division multiplexing (TDM) or frequency division multiplexing (FDM) is used for multiplexing of uplink resource for the first type MS and uplink resource for the second type MS in a frame, and

wherein the configuration index is further used for indicating number of uplink subframe(s) for the second type MS among uplink subframes in the frame; and

transmitting, at a second period, information about available uplink subchannel(s) for the first type MS in the frame when FDM is used.

2. The method of claim 1, wherein the time length of the super frame is 20 ms, and the super frame is comprised of four (4) frames, each frame 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 frame of the period.

4. The method of claim 3, wherein the ratio is set to a single fixed value for each frame of the period.

5. The method of claim 3, wherein the ratio is independently set for each frame of the period.

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

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

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

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

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

11. The method of claim 1, wherein the system configuration information further comprises downlink-to-uplink resource ratio in each super frame of the period, and the downlink-to-uplink resource ratio is represented by ceil(log2(n1)) bits when the frame is comprised of n1 number of subframes.

12. The method of claim 11, wherein the system configuration information further comprises an uplink configuration of time division multiplexing (TDM) of the first type MS and the second type MS of a frame, and the unlink configuration is represented by ceil(log2(n2*y/(x+y)) bits when the downlink-to-uplink resource ratio is given by x:

y and the uplink area of the frame is comprised of n2 number of subframes.

13. A method for, at a base station, 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 the system configuration information at a period of a time length of a frame, the time length of the frame being 5 ms,

wherein the system configuration information comprises a configuration index used for indicating whether time division multiplexing (TDM) and frequency division multiplexing (FDM) is used for multiplexing of uplink resource for the first type MS and uplink resource for the second type MS in a frame, and

wherein the configuration index is further used for indicating number of uplink subframe(s) for the second type MS among uplink subframes in the frame; and

transmitting, at a second period, information about available uplink subchannel(s) for the first type MS in the frame when FDM is used.

14. The method of claim 13, wherein the system configuration information is written in UP-MAP field of the frame.
