Abstract

A method at a network element for providing data access to a network. The method comprising establishing a primary communication channel with the network with a first wireless interface of said network element, establishing a complementary communication channel with one or more of a group of delay tolerant devices with a second wireless interface of said network element, receiving data from respective delay tolerant devices in the group, aggregating the received data and transferring said aggregated data on the established primary communication channel to the network. In an embodiment the primary and complementary channels correspond respectively to first and second spectrums, which may in turn be, respective, licensed and unlicensed spectrums.

Claims

1. A method at a network element for providing data access to a network, said method comprising:

establishing a primary communication channel with said network with a first wireless interface of said network element;

establishing a complementary communication channel with one or more of a group of delay tolerant devices with a second wireless interface of said network element;

receiving data from respective delay tolerant devices in said group;

aggregating said received data; and

transferring said aggregated data on said established primary communication channel to said network.

2. The method of claim 1, wherein said primary channel uses a first spectrum and said complementary communication channel uses a second spectrum.

3. The method of claim 2, wherein said first spectrum is a licensed spectrum and said second spectrum is an unlicensed spectrum.

4. The method of claim 2, further comprising receiving a signal indicating an allocation of resource blocks (RBs) on said second spectrum for said aggregated data.

5. The method of claim 2, further comprising transmitting a signal for an allocation of uplink data resources on said first spectrum, said allocation comprising an allocation for said aggregated data.

6. The method of claim 5, comprising conveying said aggregated data on said allocated uplink data resources.

7. The method of claim 5, further comprising linking a preamble resource to said allocated uplink data resource for conveying said aggregated data to said network.

8. The method of claim 2, further comprising allocating resource blocks (RBs) on said second spectrum for said data received from said respective delay tolerant devices.

9. The method of claim 8, further comprising linking a preamble resource to an allocated downlink resource on said second spectrum.

10. The method of claim 8, wherein said allocating of RBs includes indexing individual resource blocks with corresponding indices on respective delay tolerant devices.

11. The method of claim 1, further comprising receiving a signal from said network to trigger said data transfer.

12. The method of claim 1, wherein said wireless interfaces are software-configurable.

13. The method of claim 1, further comprising acquiring uplink synchronization information from said network in a random access channel procedure (RACH) during said establishing said primary communication channel with said network.

14. The method of claim 13, further comprising broadcasting said uplink synchronization information to said group of delay tolerant devices.

15. The method of claim 1, further comprising transmitting a preamble signal to said group for use by said delay tolerant devices in estimating a timing advance.

16. The method of claim 1, wherein said network element is user equipment (UE).

17. The method of claim 1, wherein said network element is a transmission point.

18. A network element for providing data access to a network, said network element comprising a processor configured to:

establish a primary communication channel with said network with a first wireless interface of said network element;

establish a complementary communication channel with one or more of a group of delay tolerant devices with a second wireless interface of said network element;

receive data from respective delay tolerant devices in said group;

aggregate said received data; and

transfer said aggregated data on said established primary communication channel to said network.

19. The network element of claim 18, wherein said primary channel uses a first spectrum and said complementary communication channel uses a second spectrum.

20. The network element of claim 19, wherein said first spectrum is a licensed spectrum and said second spectrum is an unlicensed spectrum.

21. The network element of claim 19, wherein the processor is further configured to transmit a signal for an allocation of uplink data resources on said first spectrum, said allocation comprising an allocation for said aggregated data.

22. The network element of claim 21, wherein the processor is further configured to convey said aggregated data on said allocated uplink resources.

23. The network element of claim 21, wherein the processor is further configured to link a preamble resource to said allocated uplink data resource for conveying said aggregated data to said network.

24. The network element of claim 19, wherein the processor is further configured to allocate resource blocks (RBs) on said second spectrum for said data received from said respective delay tolerant devices.

25. The network element of claim 24, wherein the processor is further configured to link a preamble resource to an allocated downlink resource on said second spectrum.

26. The network element of claim 24, wherein the allocated RBs includes indexing of individual resource blocks with corresponding indices on respective delay tolerant devices.

27. The network element of claim 19, wherein the processor is further configured to receive a signal indicating an allocation of resource blocks (RBs) on said second spectrum for said aggregated data.

28. The network element of claim 18, wherein the processor is further configured to receive a signal from said network to trigger said data transfer.
