Abstract

Embodiments disclosed herein provide systems and methods for providing in-band backhaul from a wireless macrocell. In a particular embodiment, a method is provided for operating a wireless communication system allocated a plurality of frequency resource segments. The method provides receiving communications for wireless transfer from the wireless communication system using a first antenna system and a second antenna system, wherein a gain of the first antenna system is higher than a gain of the second antenna system. The method further provides determining a first subset of the communications that should be transferred over the first antenna system and transferring the first subset of the communications from the first antenna system using a first portion of the frequency resource segments. The method further provides transferring the remaining communications from the second antenna system using frequency resource segments other than the first portion of the frequency resource segments.

Claims (32)

1. A method of operating a macro base station having a first antenna system and a second antenna system, wherein the macro base station is allocated a plurality of frequency resource segments, the method comprising:

receiving communications for wireless transfer from the macro base station using the first antenna system and the second antenna system, wherein a gain of the first antenna system is higher than a gain of the second antenna system;

determining a first subset of the communications intended for wireless transfer to a picocell over the first antenna system;

allocating dedicated resources comprising the first antenna system and a first portion of the plurality of frequency resource segments to the picocell;

utilizing the dedicated resources to transfer the first subset of the communications intended for wireless transfer to the picocell by transferring the first subset of the communications from the first antenna system using the first portion of the plurality of frequency resource segments for delivery to the picocell; and

transferring a second subset of the communications other than the first subset of the communications from the second antenna system using frequency resource segments other than the first portion of the plurality of frequency resource segments.

2. The method of claim 1 , wherein the plurality of resource segments comprise symbols in a time division wireless protocol.

3. The method of claim 2 , wherein the time division wireless protocol comprises a time division Long Term Evolution (LTE) wireless protocol.

4. The method of claim 1 , wherein the plurality of resource segments comprise subcarriers in a frequency division wireless protocol.

5. The method of claim 4 , wherein the frequency division wireless protocol comprises a frequency division Long Term Evolution (LTE) wireless protocol.

6. The method of claim 1 , further comprising:

modulating the first subset of the communications at a first level of modulation that is greater than a second level of modulation;

modulating the second subset of the communications other than the first subset of the communications at the second level of modulation.

7. The method of claim 1 , wherein the first antenna system transfers the first subset of the communications in a maximum throughput multiple-input multiple-output (MIMO) configuration.

8. The method of claim 1 , wherein the first portion of the plurality of resource segments comprises a contiguous portion of the plurality of resource segments.

9. The method of claim 1 , wherein the first antenna system includes a first power amplifier having a greater output power than a second power amplifier included in the second antenna system.

10. The method of claim 1 , wherein the first antenna system comprises a plurality of directional antennas.

11. A macro base station having a first antenna system and a second antenna system, wherein the macro base station is allocated a plurality of frequency resource segments, the macro base station comprising:

a communication interface configured to receive communications for wireless transfer from the macro base station using the first antenna system and the second antenna system, wherein a gain of the first antenna system is higher than a gain of the second antenna system;

a checker configured to determine a first subset of the communications intended for wireless transfer to a picocell over the first antenna system, wherein dedicated resources comprising the first antenna system and a first portion of the plurality of frequency resource segments are allocated to the picocell;

the first antenna system configured to utilize the dedicated resources to transfer the first subset of the communications intended for wireless transfer to the picocell by transferring the first subset of the communications using the first portion of the plurality of frequency resource segments for delivery to the picocell; and

the second antenna system configured to transfer a second subset of the communications other than the first subset of the communications using frequency resource segments other than the first portion of the plurality of frequency resource segments.

12. The macro base station of claim 11 , wherein the plurality of resource segments comprise symbols in a time division wireless protocol.

13. The macro base station of claim 12 , wherein the time division wireless protocol comprises a time division Long Term Evolution (LTE) wireless protocol.

14. The macro base station of claim 11 , wherein the plurality of resource segments comprise subcarriers in a frequency division wireless protocol.

15. The macro base station of claim 14 , wherein the frequency division wireless protocol comprises a frequency division Long Term Evolution (LTE) wireless protocol.

16. The macro base station of claim 11 , further comprising:

a modulator configured to modulate the first subset of the communications at a first level of modulation that is greater than a second level of modulation and modulate the second subset of the communications other than the first subset of the communications at the second level of modulation.

17. The macro base station of claim 11 , wherein the first antenna system transfers the first subset of the communications in a maximum throughput multiple-input multiple-output (MIMO) configuration.

18. The macro base station of claim 11 , wherein the first portion of the plurality of resource segments comprises a contiguous portion of the plurality of resource segments.

19. The macro base station of claim 11 , wherein the first antenna system includes a first power amplifier having a greater output power than a second power amplifier included in the second antenna system.

20. The macro base station of claim 11 , wherein the first antenna system comprises a plurality of directional antennas.
