Abstract

Aspects of the subject disclosure may include, for example, a system for modulating a first electrical signal to generate first modulated electromagnetic waves, and transmitting the first modulated electromagnetic waves on a waveguide located in proximity to a transmission medium. In one embodiment, the first electromagnetic waves can induce second electromagnetic waves that propagate on an outer surface of the transmission medium. The second electromagnetic waves can have a first spectral range that is divided into, contains or otherwise includes a first control channel and a first plurality of bands. Other embodiments are disclosed.

First claim

2. The method of claim 1 , further comprising receiving, by the apparatus, fourth electromagnetic waves on the outer surface of the waveguide, wherein the fourth electromagnetic waves are generated from third electromagnetic waves propagating on the outer surface of the transmission medium, and wherein the fourth electromagnetic waves have a second spectral range, and wherein the second spectral range is divided into a second control channel and a second plurality of bands.

3. The method of claim 2 , wherein the first spectral range and the second spectral range are separated by a guard band.

4. The method of claim 2 , wherein a first portion of the first plurality of bands and a second portion of the second plurality of bands is utilized by a first service provider of communication services, and wherein a third portion of the first plurality of bands and a fourth portion of the second plurality of bands is utilized by a second service provider of communication services.

5. The method of claim 1 , wherein the first spectral range comprises an uplink.

6. The method of claim 2 , wherein the second spectral range comprises a downlink.

7. The method of claim 2 , further comprising generating, by the apparatus, a second electrical signal from the fourth electromagnetic waves.

8. The method of claim 2 , further comprising obtaining, by the apparatus, control information in the second control channel, wherein the control information identifies an arrangement of at least one communication session in at least a portion of the second plurality of bands.

9. The method of claim 8 , wherein the at least one communication session comprises a voice communication session, a streaming video session or a data communication session.

10. The method of claim 2 , wherein the first spectral range has a first spread spectrum shape, and wherein the second spectral range has a second spread spectrum shape.

11. The method of claim 10 , wherein the first spread spectrum shape and the second spread spectrum shape have a power level and a frequency range corresponding to unlicensed spectrum.

12. The method of claim 1 , further comprising providing, by the apparatus, control information in the first control channel for identifying an arrangement of at least one communication session in at least a portion of the first plurality of bands.

13. The method of claim 12 , wherein the at least one communication session comprises a voice communication session or a data communication session.

14. The method of claim 1 , wherein each band of the first plurality of bands comprises a plurality of sub-bands.
