Abstract

A method for use in a wireless communications system includes transmitting M2M signals in an allocated narrow portion of bandwidth in a wideband structure. The allocated portion of the bandwidth may be allocated to narrow band M2M (NB-M2M) devices using a low complexity narrowband technology to access a frame structure within an existing wideband deployment.

Claims

1. A method for use in a wireless communication system comprising at least one base station, capable of Machine-to-Machine (M2M) communications, comprising at least one processor, the method comprising:

allocating, with the at least one base station processor, a narrowband structure, comprising spectrum for M2M communications, inside of a wideband structure for downlink communications with an M2M device and in an AMC subframe zone; and

allocating, with the at least one base station processor, an M2M preamble within a downlink frame in the narrowband structure for the M2M device to synchronize with the at least one base station.

2. The method of claim 1, further comprising allocating, with the base station at least one processor, the M2M preamble in a Band Adaptive Modulation and Coding (AMC) subframe zone.

3. The method of claim 1, wherein the wideband structure comprises a downlink subframe comprising a preamble, a PUSC zone, and an AMC zone and the method further comprises allocating, with the base station at least one processor, the M2M preamble in a Band Adaptive Modulation and Coding (AMC) subframe zone.

4. The method of claim 1, further comprising, allocating, with the base station at least one processor, a M2M DL-MAP in the narrowband structure.

5. The method of claim 4, further comprising, allocating, with the base station at least one processor, the M2M DL-MAP in the narrowband structure after the M2M preamble and allocating a portion of the narrowband structure after the M2M preamble for data transmission.

6. The method of claim 1, further comprising, allocating, with the base station at least one processor, a frame control header in the narrowband structure.

7. The method of claim 1, further comprising, allocating, with the base station at least one processor, a frequency control header and a M2M DL-MAP in the narrowband structure after the M2M preamble and allocating the M2M preamble, frequency control header, and the M2M DL-MAP in the AMC zone of a downlink subframe.

8. The method of claim 1, further comprising allocating, with the at least one base station processor, in the narrowband structure, an uplink subframe comprising an AMC zone for uplink M2M communications.

9. The method of claim 1, further comprising, the at least one base station processor, using a subcarrier mapping, to allocate a portion of the narrowband structure for M2M devices.

10. A wireless communications device, for use in a wireless communication system base station for Machine-to-Machine (M2M) communications, comprising:

a processor with executable instructions for allocating a narrowband structure, comprising spectrum for M2M communications, inside of a wideband structure for downlink communications with an M2M device and in an AMC subframe zone; and

allocating, an M2M preamble within a downlink frame in the narrowband structure for the M2M device to synchronize with the at least one base station.

11. The wireless communications device of claim 10, wherein the processor comprises executable instructions for allocating the M2M preamble in a Band Adaptive Modulation and Coding (AMC) subframe zone.

12. The wireless communications device of claim 10, wherein the wideband structure comprises a downlink subframe comprising a preamble, a PUSC zone, and an AMC zone and wherein the processor comprises executable instructions for allocating the M2M preamble in a Band Adaptive Modulation and coding (AMC) subframe zone.

13. The wireless communications device of claim 10, wherein the processor further comprises executable instructions for allocating a M2M DL-MAP in the narrowband structure.

14. The wireless communications device of claim 13, wherein the processor further comprises executable instructions for allocating the M2M DL-MAP in the narrowband structure after the M2M preamble and for allocating a portion of the narrowband structure after the M2M preamble for data transmission.

15. The wireless communications device of claim 10, wherein the processor further comprises executable instructions for allocating a frame control header in the narrowband structure.

16. The wireless communications device of claim 10, wherein the processor further comprises executable instructions for allocating a frequency control header and a M2M DL-MAP in the narrowband structure after the M2M preamble and for allocating the M2M preamble, frequency control header and the M2M DL-MAP in the AMC of a downlink sub frame.

17. The wireless communications device of claim 10, wherein the processor further comprises executable instructions for allocating, in the narrowband structure, an uplink subframe comprising an AMC zone for uplink M2M communications.

18. The wireless communications device of claim 10, wherein the processor further comprises executable instructions for, using a subcarrier mapping, to allocate a portion of the narrowband structure for M2M devices.
