7. The method of claim 1 , wherein the at least one potentially interfering base station comprises another H semi-autonomous base station.

8. A method operable by a user equipment, comprising:

measuring a received signal strength for a semi-autonomous base station;

preparing a measurement report, wherein the measurement report includes the received signal strength for the semi-autonomous base station; and

sending the measurement report to a first base station.

9. The method of claim 8 , wherein the semi-autonomous base station is a restricted semi-autonomous base station, and wherein the user equipment does not belong to a closed subscriber group for the semi-autonomous base station.

10. The method of claim 9 , wherein the first base station is the semi-autonomous base station, and further comprising:

performing a reselection to the semi-autonomous base station;

performing access procedures with the semi-autonomous base station for a first time;

registering with a mobility management entity;

receiving a page from the mobility management entity; and

performing access procedures with the semi-autonomous base station for a second time, wherein the user equipment performs access procedures with the semi-autonomous base station for the second time before sending the measurement report to the semi-autonomous base station.

11. The method of claim 10 , wherein performing a reselection to the semi-autonomous base station occurs because downlink signals from the semi-autonomous base station are interfering with downlink signals from a second base station.

12. The method of claim 11 , further comprising performing access procedures with the second base station.

13. A semi-autonomous base station comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to:

reserve a portion of bandwidth for a user equipment;

send notification of the reserved portion of bandwidth to at least one potentially interfering base station;

perform a data exchange with the user equipment using the reserved portion of bandwidth; and

send notification to the potentially interfering base stations releasing the reserved portion of bandwidth.

14. The semi-autonomous base station of claim 13 , wherein the notification releasing the reserved portion of bandwidth is sent when the data exchange with the user equipment has stopped.

15. The semi-autonomous base station of claim 13 , wherein the notification releasing the reserved portion of bandwidth is sent when the user equipment enters idle mode.

16. The semi-autonomous base station of claim 13 , wherein the at least one potentially interfering base station is identified through a self organizing network (SON) server.

17. The semi-autonomous base station of claim 13 , wherein the semi-autonomous base station communicates with the at least one potentially interfering base station through a backhaul connection.

18. The semi-autonomous base station of claim 13 , wherein the semi-autonomous base station communicates with the at least one potentially interfering base station through an X2 link.

19. The semi-autonomous base station of claim 13 , wherein the at least one potentially interfering base station comprises another semi-autonomous base station.

20. A user equipment comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to:

measure a received signal strength for a semi-autonomous base station;

prepare a measurement report, wherein the measurement report includes the received signal strength for the semi-autonomous base station; and

send the measurement report to a first base station.

21. The user equipment of claim 20 , wherein the semi-autonomous base station is a restricted semi-autonomous base station, and wherein the user equipment does not belong to a closed subscriber group for the semi-autonomous base station.

22. The user equipment of claim 21 , wherein the first base station is the semi-autonomous base station, and wherein the instructions are further executable to:

perform a reselection to the semi-autonomous base station;

perform access procedures with the semi-autonomous base station for a first time;

register with a mobility management entity;

receive a page from the mobility management entity; and

perform access procedures with the semi-autonomous base station for a second time, wherein the user equipment performs access procedures with the semi-autonomous base station for the second time before sending the measurement report to the semi-autonomous base station.

23. The user equipment of claim 22 , wherein performing a reselection to the semi-autonomous base station occurs because downlink signals from the semi-autonomous base station are interfering with downlink signals from a second base station.

24. The user equipment of claim 23 , wherein the instructions are further executable to perform access procedures with the second base station.

25. An apparatus comprising:

means for reserving a portion of bandwidth for a user equipment;

means for sending notification of the reserved portion of bandwidth to at least one potentially interfering base station;

means for performing a data exchange with the user equipment using the reserved portion of bandwidth; and

means for sending notification to the at least one potentially interfering base station releasing the reserved portion of bandwidth.

26. The apparatus of claim 25 , wherein the notification releasing the reserved portion of bandwidth is sent when the data exchange with the base station has stopped.

27. The apparatus of claim 25 , wherein the at least one potentially interfering base station is identified through a self organizing network server.
