Abstract

A method of wireless communication includes communicating with a base station using an extended special subframe. Communicating with the base station using the extended special subframe may be performed by disabling an uplink pilot time slot and an adjacent uplink subframe.

Claims

1. A method of wireless communication, comprising:

communicating with a base station using an extended special subframe by disabling an uplink pilot time slot and an adjacent uplink subframe.

2. The method of claim 1, further comprising dynamically adjusting a length of the extended special subframe based at least in part on a location of a user equipment (UE).

3. The method of claim 1, further comprising alternating between uplink/downlink subframe configurations using a first extended special subframe and a second extended special subframe.

4. The method of claim 1, further comprises communicating using a first extended special subframe when a position of a user equipment (UE) is within a first predetermined cell radius greater than a predetermined threshold radius.

5. The method of claim 4, further comprises communicating using a second extended special subframe when the position of the UE is within a second predetermined cell radius that is greater than the first predetermined cell radius.

6. The method of claim 5, in which a length of the first extended special subframe is less than the length of the second extended special subframe.

7. The method of claim 1, further comprising dynamically adjusting a subframe at which to being uplink communication by muting the uplink pilot time slot and the adjacent uplink subframe.

8. The method of claim 1, in which an extended timing advance is applied to the extended special subframe.

9. The method of claim 1, in which the method is performed within an aircraft.

10. A method of wireless communication, comprising:

detecting a position of a user equipment (UE) as being within a first extended cell radius or a second extended cell radius; and

communicating with the UE using a special subframe that extends over an uplink pilot time slot and one or more disabled, adjacent uplink subframes.

11. The method of claim 10, further comprising alternating between uplink/downlink subframe configurations using at least a first extended special subframe and a second extended special subframe.

12. The method of claim 11, in which a length of the first extended special subframe is less than the length of the second extended special subframe.

13. The method of claim 10, further comprises communicating using a first extended special subframe when the position of the UE is within the first extended cell radius greater than a predetermined threshold radius.

14. The method of claim 10, further comprises communicating using a second extended special subframe when the position of the UE is within the second extended cell radius, which is greater than the first extended cell radius.

15. An apparatus operable to provide wireless communication, the apparatus comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor being operable;

to communicate with a base station using an extended special subframe by disabling an uplink pilot time slot and an adjacent uplink subframe.

16. The apparatus of claim 15, in which the at least one processor is further operable to dynamically adjust a length of the extended special subframe based at least in part on a location of a user equipment (UE).

17. The apparatus of claim 15, in which the at least one processor is further operable to alternate between uplink/downlink subframe configurations using at least a first extended special subframe and a second extended special subframe.

18. The apparatus of claim 15, in which the at least one processor is further operable to communicate using a first extended special subframe when a position of a user equipment (UE) is within a first predetermined cell radius greater than a predetermined threshold radius.

19. The apparatus of claim 18, in which the at least one processor is further operable to communicate using a second extended special subframe when the position of the UE is within a second predetermined cell radius that is greater than the first predetermined cell radius.

20. The apparatus of claim 19, in which a length of the first extended special subframe is less than the length of the second extended special subframe.

21. The apparatus of claim 15, in which the at least one processor is further operable to dynamically adjust a subframe at which to being uplink communication by muting the uplink pilot time slot and the adjacent uplink subframe.

22. The apparatus of claim 15, in which an extended timing advance is applied to the extended special subframe.
