Abstract

A network device may select one or more secondary bands in a spectrum based on a measure of quality of the one or more secondary bands; transmit information identifying the one or more secondary bands to an end unit; code, based on a coding scheme, a data flow to obtain multiple data signals that represent the data flow; and transmit, towards the end unit, the multiple data signals via the one or more secondary bands and a primary band.

Claims

1. A method comprising:

selecting, by a network device, one or more secondary bands in a spectrum based on a measure of quality of the one or more secondary bands;

transmitting, by the network device, information identifying the one or more secondary bands to an end unit;

coding, by the network device and based on a coding scheme, a data flow to obtain a plurality of data signals that represent the data flow;

transmitting, by the network device and towards the end unit, the plurality of data signals via the one or more secondary bands and a primary band;

monitoring a measure of performance of the transmission of the plurality of data signals via the one or more secondary bands; and

discontinuing transmission of the plurality of data signals via the one or more secondary bands when the measure of performance satisfies a particular threshold.

2. The method of claim 1, wherein coding the data flow includes orthogonally coding the data flow.

3. The method of claim 1, wherein a quantity of obtained data signals is based on a quantity of secondary bands selected by the network device.

4. The method of claim 1, wherein measuring the quality of the one or more secondary bands includes:

measuring interference or noise,

measuring total radiating power, or

measuring reliability in a communication between the network device and an external network not accessible to the end unit.

5. The method of claim 1, wherein the network device corresponds to a network device in a back-end network of a cellular network.

6. A method comprising:

selecting, by a network device, one or more secondary bands in a spectrum based on a measure of quality of the one or more secondary bands;

transmitting, by the network device, information identifying the one or more secondary bands to an end unit;

coding, by the network device and based on a coding scheme, a data flow to obtain a plurality of data signals that represent the data flow;

transmitting, by the network device and towards the end unit, the plurality of data signals via the one or more secondary bands and a primary band; and

determining a quantity of secondary bands to be selected based on the measure of quality of the one or more secondary bands,

wherein selecting the one or more secondary bands includes selecting the determined quantity of secondary bands.

7. The method of claim 6, further comprising:

determining an updated quantity of secondary bands based on a change in the measure of quality of the one or more secondary bands.

8. A system comprising:

a network device comprising processor circuitry to;

select one or more secondary bands in a spectrum based on a measure of quality of the one or more secondary bands;

transmit information identifying the one or more secondary bands to an end unit;

code, based on a coding scheme, a data flow to obtain a plurality of data signals that represent the data flow;

transmit, towards the end unit, the plurality of data signals via the one or more secondary bands and a primary band;

monitor a measure of performance of the transmission of the plurality of data signals via the one or more secondary bands; and

discontinue transmission of the plurality of data signals via the one or more secondary bands when the measure of performance satisfies a particular threshold.

9. The system of claim 8, wherein when coding the data flow, the network device is to orthogonally code the data flow.

10. The system of claim 8, wherein a quantity of obtained data signals is based on a quantity of secondary bands selected by the network device.

11. The system of claim 8, wherein the network device is further to:

determining a quantity of secondary bands to be selected based on the measure of quality of the one or more secondary bands,

wherein when selecting the one or more secondary bands, the network device is further to select the determined quantity of secondary bands.

12. The system of claim 8, wherein the network device is further to:

determining an updated quantity of secondary bands based on a change in the measure of quality of the one or more secondary bands.

13. The system of claim 8, wherein when measuring the quality of the one or more secondary bands, the network device is to:

measure interference or noise,

measure total radiating power, or

measure reliability in a communication between the network device and an external network not accessible to the end unit.

14. The system of claim 8, wherein the network device corresponds to a network device in a back-end network of a cellular network.

15. The system of claim 8, wherein the network device is a first network device,

wherein when transmitting, towards the end unit, the plurality of data signals via the one or more secondary bands and a primary band, the first network device is to transmit, towards the end unit, the plurality of data signals via the one or more secondary bands and a primary band, the transmitting being performed via a second network device.

16. A non-transitory computer-readable medium for storing instructions, the instructions comprising:

a plurality of instructions which, when executed by one or more processors associated with a first device, cause the one or more processors to;

receive, via a primary band from a second device in a back-end network, information identifying one or more secondary bands;

receive, from the second device and via the primary band and the one or more secondary bands, a plurality of data signals representative of a data flow originating from an external network that is separate from the back-end networks;

provide measures of performance of the transmission of the data flow via the one or more secondary bands; and

discontinue receipt of the plurality of data signals via the one or more secondary bands when the measure of performance satisfies a particular threshold.

17. The non-transitory computer-readable medium of claim 16, wherein the plurality of instructions further cause the one or more processors to:

orthogonally decode the data signals to recover the data flow.

18. The non-transitory computer-readable medium of claim 16, wherein the data flow is orthogonally coded.

19. The non-transitory computer readable medium of claim 16, wherein a quantity of the plurality of data signals is based on a quantity of the one or more secondary bands.

20. The non-transitory computer readable medium of claim 16, wherein the measurement of performance includes:

a measurement interference or noise, or

a measurement of total radiating power.
