Abstract

Systems and methodologies are described that facilitate supporting narrowband and wideband operation within a wideband wireless communication environment. For example, wideband operation can be enhanced by enabling faster communication of information as compared to narrowband operation, transfer of supplemental data available to wideband devices, and the like. Pursuant to another example, timing of information transfer can be scheduled over a plurality of subbands to enable a narrowband device to obtain a set of information over one of the subbands during a set of time intervals, while a wideband device can receive the set of information over the plurality of subbands during a reduced set of time intervals.

Claims

1. A method of operating a base station, the method comprising:

transmitting, from the base station, first information from a set of information to both a narrowband wireless terminal and a wideband wireless terminal via a first subband, from a set of frequency subbands, during a first time interval in a set of time intervals, said set of information including said first information and a set of additional information; and

transmitting, from the base station, said additional information to the wideband wireless terminal during said first time interval via additional frequency subbands from said set of frequency subbands.

2. The method of claim 1, further comprising:

transmitting said additional information to the narrowband wireless terminal via said first subband during additional time intervals in said set of time intervals.

3. The method of claim 2,

wherein said additional time intervals include a second time interval;

wherein said set of additional information includes second information; and

wherein said transmitting said additional information to the narrowband wireless terminal includes;

transmitting said second information via the first subband during said second time interval.

4. The method of claim 3, further comprising:

transmitting said first information to the wideband wireless terminal via a second subband during said second time interval, said second subband being one of said additional frequency subbands.

5. The method of claim 4,

wherein said additional time intervals further include a third time interval;

wherein said set of additional information includes third information; and

wherein the method further comprises;

transmitting the third information to the wideband wireless terminal via a third subband during said second time interval.

6. The method of claim 5, wherein said third subband is different from a subband that was used during said first time interval to communicate said third information.

7. The method of claim 1, further comprising:

transmitting different subsets of said set of information to said wideband wireless terminal via said additional frequency subbands during different time intervals in said set of time intervals, said different time intervals following said first time interval.

8. The method of claim 1, further comprising:

inhibiting transmission over said additional frequency subbands during time intervals in the set of time intervals other than said first time interval.

9. The method of claim 1, further comprising transferring supplemental data over said additional frequency subbands during time intervals in the set of time intervals other than the first time interval.

10. A base station, comprising:

at least one processor configured to;

transmit first information from a set of information to both a narrowband wireless terminal and a wideband wireless terminal via a first subband, from a set of frequency subbands, during a first time interval in a set of time intervals, said set of information including said first information and a set of additional information; and

transmit said additional information to the wideband wireless terminal during said first time interval via additional frequency subbands from said set of frequency subbands; and

a memory coupled to said at least one processor.

11. The base station of claim 10, wherein said at least one processor is further configured to:

transmit said additional information to the narrowband wireless terminal via said first subband during additional time intervals in said set of time intervals.

12. The base station of claim 11, wherein said additional time intervals include a second time interval;

wherein said set of additional information includes second information; and

wherein said at least one processor is further configured to transmit, as part of transmitting said additional information to the narrowband wireless terminal, said second information via the first subband during said second time interval.

13. The base station of claim 12, wherein said at least one processor is configured to:

transmit said first information to the wideband wireless terminal via a second subband during said second time interval, said second subband being one of said additional frequency subbands.

14. The base station of claim 13,

wherein said additional time intervals further include a third time interval;

wherein said set of additional information includes third information; and

wherein said at least one processor is further configured to;

transmit said third information to the wideband wireless terminal via a third subband during said second time interval.

15. A base station, comprising:

means for storing information; and

means for transmitting first information from a set of information to both a narrowband wireless terminal and a wideband wireless terminal via a first subband, from a set of frequency subbands during a first time interval in a set of time intervals, said set of information including said first information and a set of additional information;

wherein said means for transmitting are also for transmitting said additional information to the wideband wireless terminal during said first time interval via additional frequency subbands from said set of frequency subbands.

18. The base station of claim 15, further comprising:

means for inhibiting transmission over said additional frequency subbands during time intervals in the set of time intervals other than said first time interval.

19. The base station of claim 15,

wherein said means for transmitting are also for transmitting supplemental data over said additional frequency subbands during time intervals in the set of time intervals other than the first time interval.

20. A non-transitory machine-readable medium having stored thereon machine-executable instructions for controlling a communications device, said non-transitory machine-readable medium comprising:

instructions for causing the communications device to transmit first information in a set of information to both a narrowband wireless terminal and a wideband wireless terminal via a first subband, from a set of frequency subbands, during a first time interval in a set of time intervals, said set of information including said first information and a set of additional information; and
