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 for a cluster head device for providing data access to a network, said method comprising:

receiving from said network a control signal to initiate a random access procedure for a group of delay tolerant devices;

based on the control signal, sending a group signaling message to the group of delay tolerant devices, the group signaling message including a group identifier that associates the cluster head device and the group of delay tolerant devices;

initiating a random access procedure with said network to establish a primary communication channel with the network for the group using the group identifier, wherein said primary communication channel uses a first spectrum;

establishing a complementary communication channel with the group of delay tolerant devices, wherein said complementary communication channel uses a second spectrum;

receiving data from respective delay tolerant devices in said group on said complementary communication channel;

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 first spectrum is a licensed spectrum and said second spectrum is an unlicensed spectrum.

3. The method of claim 1, further comprising receiving a signal indicating an allocation of resource blocks (RBs) on said second spectrum for said aggregated data.

4. The method of claim 1, 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.

5. The method of claim 4, comprising conveying said aggregated data on said allocated uplink data resources.

6. The method of claim 4, further comprising linking a preamble resource to said allocated uplink data resource for conveying said aggregated data to said network.

7. The method of claim 1, further comprising allocating resource blocks (RBs) on said second spectrum for said data received from said respective delay tolerant devices.

8. The method of claim 7, further comprising linking a preamble resource to an allocated downlink resource on said second spectrum.

9. The method of claim 7, wherein said allocating of RBs includes indexing individual resource blocks with corresponding indices on respective delay tolerant devices.

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

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

12. 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.

13. The method of claim 12, further comprising broadcasting said uplink synchronization information to said group of delay tolerant devices.

14. 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.

15. The method of claim 1, wherein said cluster head device is user equipment (UE).

16. The method of claim 1, wherein said cluster head device is a transmission point.

17. A cluster head device for providing data access to a network, said device comprising, a non-transitory memory configured to store instructions, and a processor configured to receive instructions from the non-transitory memory to cause the cluster head device to:

receive from said network a control signal to initiate a random access procedure for a group of delay tolerant devices;

based on the control signal, send a group signaling message to the group of delay tolerant devices, the group signaling message including a group identifier that associates the cluster head device and the group of delay tolerant devices;

initiate a random access procedure with said network to establish with the network a primary communication channel for the group using the group identifier, wherein said primary communication channel uses a first spectrum;

establish a complementary communication channel with the group of delay tolerant devices, wherein said complementary communication channel uses a second spectrum;

receive data from respective delay tolerant devices in said group on said complementary communication channel;

aggregate said received data; and

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

18. The device of claim 17, wherein said first spectrum is a licensed spectrum and said second spectrum is an unlicensed spectrum.

19. The device of claim 17, 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.

20. The device of claim 19, wherein the processor is further configured to convey said aggregated data on said allocated uplink resources.

21. The device of claim 19, 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.

22. The device of claim 17, 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.

23. The device of claim 22, wherein the processor is further configured to link a preamble resource to an allocated downlink resource on said second spectrum.

24. The device of claim 22, wherein the allocated RBs includes indexing of individual resource blocks with corresponding indices on respective delay tolerant devices.

25. The device of claim 17, 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.

26. The device of claim 17, wherein the processor is further configured to receive a signal from said network to trigger said data transfer.

27. The device of claim 17, wherein said wireless interfaces are software-configurable.

28. The device of claim 17, wherein the processor is further configured to acquire uplink synchronization information from said network in a random access channel procedure (RACH), during said establishing said primary communication channel with said network.

29. The device of claim 28, wherein the processor is further configure to broadcast said uplink synchronization information to said group of delay tolerant devices.

30. The device of claim 17, wherein the processor is further configured to transmit a preamble signal to said group for use by said delay tolerant devices in estimating a timing advance.

31. The device of claim 17, wherein said device is user equipment (UE).

32. The device of claim 17, wherein said device is a transmission point.
