Abstract
Abstract A mobile station is instructed to first transmit at relatively high sending power on a channel being assigned despite possible interference and is then instructed before a first time interval has elapsed to transmit at a more optimal power level to reduce interference. The power level on the channel is then periodically monitored at a second time interval greater than the first time interval. Momentarily increased interference is therefore tolerated in exchange for increased assurance of channel assignment. The interference is quickly reduced by implementing a fast power regulating function as compared to a slower ongoing channel power monitoring function.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A method of regulating transmission power of a mobile station at the time of assignment of a channel, comprising the steps of: directing said mobile station to first transmit at a relatively high sending power on said channel despite possible interference; directing said mobile station before a first time interval has elapsed to then transmit at a more optimal power level to reduce interference; and periodically monitoring a power level on said channel at approximately a second time interval greater than said first time interval.
Claim 2
Independent Claim
85 words
A method of regulating transmission power of a mobile station at the time of assignment of a channel, comprising the steps of: directing said mobile station to first transmit at a relatively high sending power on said channel despite possible interference; directing said mobile station before a first time interval has elapsed to then transmit at a more optimal power level to reduce interference; and periodically monitoring a power level on said channel at approximately a second time interval greater than said first time interval.
Claim 3
Dependent Claim
26 words
The method of claim 1 wherein said relatively high sending power is the maximum sending power allowed in a cell to which said channel is allocated.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein said first time interval is sufficient to receive a channel identifier transmitted by said mobile station.
Claim 5
Dependent Claim
15 words
The method of claim 3 wherein said second time interval is several seconds in duration.
Claim 6
Independent Claim
90 words
An apparatus for regulating transmission power of a mobile station at the time of assignment of a channel, comprising: first means for directing said mobile station to first transmit at a relatively high sending power on said channel despite possible generation of interference; second means for directing said mobile station before a first time interval has elapsed to transmit at a more optimal power level to reduce interference;and means for periodically monitoring the power level on said channel at approximately a second time interval greater than said first time interval.
Claim 7
Independent Claim
90 words
An apparatus for regulating transmission power of a mobile station at the time of assignment of a channel, comprising: first means for directing said mobile station to first transmit at a relatively high sending power on said channel despite possible generation of interference; second means for directing said mobile station before a first time interval has elapsed to transmit at a more optimal power level to reduce interference;and means for periodically monitoring the power level on said channel at approximately a second time interval greater than said first time interval.
Claim 8
Dependent Claim
26 words
The apparatus of claim 5 wherein said relatively high sending power is the maximum sending power allowed in a cell to which said channel is allocated.
Claim 9
Dependent Claim
22 words
The apparatus of claim 5 wherein said first time interval is sufficient to receive a channel identifier transmitted by said mobile station.
Claim 10
Dependent Claim
15 words
The apparatus of claim 7 wherein said second time interval is several seconds in duration.
