Abstract

Systems and methods are disclosed for permitting higher transmit power at a mobile device. In one embodiment, a method is disclosed, comprising: receiving, at a base station, an emergency request from a mobile device; sending, from the base station to a neighboring base station, a high power reservation message to reserve one or more radio resource blocks at the neighboring base station for non-use; and sending, from the base station to the mobile device, a resource allocation including the one or more radio resource blocks and a power control message requesting high transmit power.

Claims

1. A method, comprising:

receiving, at a base station, an emergency request from a mobile device;

coordinating a resource allocation with a self-organizing network (SON) module located at a coordinating node, the coordinating node being an X2 aggregation point;

sending, from the base station to a neighboring base station via the coordinating node, a high power reservation message to reserve one or more radio resource blocks at the neighboring base station for non-use; and

sending, from the base station to the mobile device, a resource allocation including the one or more radio resource blocks and a power control message requesting high transmit power.

2. The method of claim 1, further comprising identifying whether the emergency request is an emergency call request or indicates emergency status.

3. The method of claim 1, further comprising identifying radio resources based on usage of radio resources by nearby mobile devices, nearby base stations, or both.

4. The method of claim 1, further comprising coordinating scheduling with the neighboring base station via the coordinating node via an X2 protocol message.

5. The method of claim 1, wherein the base station is an eNodeB, the mobile device is a user equipment (UE), and the high power reservation message is a High Interference Indicator (HII) message communicated via an X2 protocol message.

6. The method of claim 1, wherein the high power reservation message comprises a High Interference Indicator (HII) message and a Relative Narrowband Transmit Power (RNTP) message.

7. The method of claim 1, wherein the emergency request is an emergency attach request without user equipment device authentication.

8. The method of claim 1, wherein the emergency request is a request to make an emergency call.

9. The method of claim 1, wherein the power control message identifies the one or more radio resource blocks.

10. The method of claim 1, wherein the one or more radio resource blocks are resource blocks designated by frequency or time.

11. The method of claim 1, wherein the mobile device is directed to use its maximum transmit power for uplink transmission to the base station.

12. The method of claim 1, wherein the base station uses a higher transmit power for downlink transmission to the mobile device.

13. A base station, comprising:

a processing module for providing wireless communications to mobile users;

a core network interface coupled to the processing module and in communication with a core network; and

an access interface coupled to the processing module, in communication with one or more mobile devices, and capable of being used for emergency communications by the one or more mobile devices;

wherein the processing module is configured to;

receive, at the base station, an emergency request from a mobile device;

coordinate a resource allocation with a self-organizing network (SON) module located at a coordinating node, the coordinating node being an X2 aggregation point;

send, from the base station to a neighboring base station via the coordinating node, a high power reservation message to reserve one or more radio resource blocks at the neighboring base station for non-use; and

send, from the base station to the mobile device, a resource allocation including the one or more radio resource blocks and a power control message requesting high transmit power.

14. The method of claim 13, wherein the base station is an eNodeB, the mobile device is a user equipment (UE), and the high power reservation message is a High Interference Indicator (HII) message communicated via an X2 protocol message.

15. The method of claim 13, wherein the high power reservation message comprises a High Interference Indicator (HII) message and a Relative Narrowband Transmit Power (RNTP) message.

16. The method of claim 13, wherein the emergency request is an emergency attach request without user equipment device authentication.

17. The method of claim 13, wherein the emergency request is a request to make an emergency call.

18. The method of claim 13, wherein the power control message identifies the one or more radio resource blocks.

19. The method of claim 13, wherein the one or more radio resource blocks are resource blocks designated by frequency or time.

20. The method of claim 13, wherein the mobile device is directed to use its maximum transmit power for uplink transmission to the base station.
