Methods of controlling transmission power level based on remaining power level in immediately preceding time period
First Claim
1. A method of controlling transmission power used for wireless transmission in a wireless communication device, the method comprising:
- calculating a remaining power level of a third period based on a tolerant power level of a first period and a remaining power level of a second period, the third period included in the first period and being a period from a current time to a point in time following the current time, the second period being a period from the current time to a point in time preceding the current time, the tolerant power level being a total transmission power level available to the wireless communication device for the wireless transmission during a certain period;
calculating a transmission power level of the third period based on a target power level and the remaining power level of the third period; and
generating a power control signal for determining a power level of a transmission signal unit based on the transmission power level of the third period,wherein the calculating of the transmission power level of the third period comprises,comparing the remaining power level of the third period with at least one of a plurality of reference levels, anddetermining the transmission power level of the third period based on results of the comparing.

10. A method of controlling transmission power used for wireless transmission in a wireless communication device, the method comprising:
-
calculating a remaining power level of a third period based on a tolerant power level of a first period and a remaining power level of a second period, the third period included in the first period and being a period from a current time to a point in time following the current time, the second period being a period from the current time to a point in time preceding the current time, the tolerant power level being a total transmission power level available to the wireless communication device for the wireless transmission during a certain period; calculating a transmission power level of the third period based on a target power level and the remaining power level of the third period; and generating a power control signal for determining a power level of a transmission signal unit based on the transmission power level of the third period, wherein the first period is less than a sum of the second period and the third period, and the calculating of the remaining power level of the third period comprises, calculating a tolerant power level of the third period from the tolerant power level of the first period, and calculating the remaining power level of the third period so that the remaining power level of the third period becomes a sum of the tolerant power level of the third period and a value obtained by adjusting the remaining power level of the second period by a weight value.

18. A method of controlling transmission power used for wireless transmission in a wireless communication device, the method comprising:
-
calculating, by a controller, remaining emission energy of a third period based on tolerant emission energy of a first period and used energy which was emitted for the wireless transmission during a second period, the third period included in the first period and being a period from a current time to a point in time following the current time, the second period being from the current time to a point in time preceding the current time, the tolerant emission energy being a total transmission energy available to the wireless communication device for the wireless transmission during a certain period; calculating, by the controller, a transmission power level of the third period based on the remaining emission energy of the third period and a target power level of the third period; and generating, by the controller, a power control signal for controlling a power level of a transmission signal unit based on the transmission power level, wherein the calculating of the transmission power level of the third period comprises, comparing the remaining power level of the third period with at least one of a plurality of reference levels, and determining the transmission power level of the third period based on results of the comparing. - View Dependent Claims (19)
