Method and apparatus for power control a communication

Abstract

In a communication system ( 100 ), a method and apparatus provide for efficient power control between base station ( 101 ) and mobile stations ( 102 - 104 ). A controller is configured for determining duty cycle of a communication channel, and for controlling power level of the communication channel based on the determined duty cycle. The controller may compare the determined duty cycle against a duty cycle threshold. An adjustment for controlling power level may be based on the comparison.

1 . In a communication system, a method comprising: 
 determining traffic to pilot channel power ratio of a traffic channel for communication between a mobile station and a base station in said communication system, wherein said traffic to pilot channel power ratio is determined based on communications of said traffic channel;    determining duty cycle of data frame transmissions of a dedicated control channel associated with said traffic channel, wherein said dedicated control channel is for maintaining communications of said traffic channel, wherein said duty cycle of data frame transmissions is based on the possible number of frame transmissions over a period of time;    adjusting said traffic to pilot channel power ratio based on said determined duty cycle;    communicating said traffic channel in accordance with said determined traffic to pilot channel power ratio, and said dedicated control channel in accordance with said adjusted traffic to pilot channel power ratio.    
   
   
       2 . In a communication system, an apparatus comprising: 
 means for determining traffic to pilot channel power ratio of a traffic channel for communication between a mobile station and a base station in said communication system, wherein said traffic to pilot channel power ratio is determined based on communications of said traffic channel;    means for determining duty cycle of data frame transmissions of a dedicated control channel associated with said traffic channel, wherein said dedicated control channel is for maintaining communications of said traffic channel, wherein said duty cycle of data frame transmissions is based on the possible number of frame transmissions over a period of time;    means for adjusting said traffic to pilot channel power ratio based on said determined duty cycle;    means for communicating said traffic channel in accordance with said determined traffic to pilot channel power ratio, and said dedicated control channel in accordance with said adjusted traffic to pilot channel power ratio.
