Abstract

An entity, such as a base station, in a wireless communications network performs power control of a control channel based on one or more characteristics of a message in the control channel. For example, the control channel can be a paging channel. The one or more characteristics include, as examples, the size and/or the type of message in the control channel.

First claim

What is claimed is:

1. A method for performing wireless communications in a mobile communications network, comprising:
a communication device determining a type of a message comprising one or more fields to be communicated in a control channel;
the communication device determining a power level for transmission of the message using the control channel, wherein a first power level used for an acknowledgement message is based on a default power level, wherein said determining the power level for the message comprises determining a second power level based on the one or more fields of the message, wherein the one or more fields of the message are different from an acknowledgement message, wherein the second power level is based on a power level that is higher than the default power level;
the communication device setting the power level for transmission of the message based on said determining; and
after setting the power level for transmission, the communication device transmitting the message in the control channel using the determined power level.

2. The method of claim 1 , wherein said determining the power level is also based on the size of the message.

3. The method of claim 2 , wherein said determining the power level comprises using a higher power level for larger messages and using a lower power level for smaller messages.

4. The method of claim 1 , wherein said determining the power level comprises using a higher power level for higher priority messages and using a lower power level for lower priority messages.

5. The method of claim 1 , wherein the control channel comprises a paging channel.

6. The method of claim 1 , wherein the communication device comprises a base station.

7. The method of claim 1 , wherein the mobile communications network comprises one of an IS-95, CDMA (code-division multiple access) 2000, 1×EV-DO, 1×EV-DV, UMTS (Universal Mobile Telecommunication System), and EGPRS (Enhanced General Packet Radio Service) system.

8. A communication device for performing wireless communicating, comprising:
communication circuitry for performing the wireless communication;
processing hardware coupled to the communication circuitry, wherein the processing hardware is configured to operate with the communication circuitry to:
determine a type of a message comprising one or more fields to be communicated in a control channel;
determine a power level for transmission of the message using the control channel, wherein a first power level used for an acknowledgement message is based on a default power level, wherein said determining the power level for the message comprises determining a second power level based on the one or more fields of the message, wherein the one or more fields of the message are different from an acknowledgement message, wherein the second power level is based on a power level that is higher than the default power level;
set the power level for transmission of the message based on said determining; and
after setting the power level for transmission, transmit the message in the control channel using the determined power level.

9. The communication device of claim 8 , wherein determining the power level is also based on the size of the message.

10. The communication device of claim 9 , wherein determining the power level comprises using a higher power level for larger messages and using a lower power level for smaller messages.

11. The communication device of claim 8 , wherein determining the power level comprises using a higher power level for higher priority messages and using a lower power level for lower priority messages.

12. The communication device of claim 8 , wherein the control channel comprises a paging channel.

13. The communication device of claim 8 , wherein the communication device comprises a base station.

14. The communication device of claim 8 , wherein the wireless communication is performed using one of an IS-95, CDMA (code-division multiple access) 2000, 1×EV-DO, 1×EV-DV, UMTS (Universal Mobile Telecommunication System), and EGPRS (Enhanced General Packet Radio Service) system.

15. A non-transitory, computer accessible memory medium storing program instructions for performing wireless communications in a mobile communications network, wherein the program instructions are executable by a processor of a communication device to:
determine a type of a message comprising one or more fields to be communicated in a control channel;
determine a power level for transmission of the message using the control channel, wherein a first power level used for an acknowledgement message is based on a default power level, wherein said determining the power level for the message comprises determining a second power level based on the one or more fields of the message, wherein the one or more fields of the message are different from an acknowledgement message, wherein the second power level is based on a power level that is higher than the default power level;
set the power level for transmission of the message based on said determining; and
after setting the power level for transmission, transmit the message in the control channel using the determined power level.

16. The non-transitory, computer accessible memory medium of claim 15 , wherein determining the power level is also based on the size of the message.

17. The non-transitory, computer accessible memory medium of claim 16 , wherein determining the power level comprises using a higher power level for larger messages and using a lower power level for smaller messages.

18. The non-transitory, computer accessible memory medium of claim 15 , wherein determining the power level comprises using a higher power level for higher priority messages and using a lower power level for lower priority messages.

19. The non-transitory, computer accessible memory medium of claim 15 , wherein the control channel comprises a paging channel.

20. The non-transitory, computer accessible memory medium of claim 15 , wherein the communication device comprises a base station.
