Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
162 words
A communication station for communicating with a second station in a cellular-communication network using spread spectrum modulation wherein the second station transmits power commands to the communication station based on a received power level from the communication station, the communication station comprising: a transmitter having an adjustable transmitter power level for transmitting spread-spectrum signals; means for sequentially receiving power commands from a second station with which communication is being conducted; means for comparing a sequence of at least two of the received power commands to determine if the received commands in the sequence match; and means for adjusting the transmitter power level at a same rate as the reception of the power commands by steps; wherein if the command sequence does match, a magnitude of subsequent steps in the transmitter power level are increased by a fixed percentage and if the command sequence does not match, the magnitude of subsequent steps in the transmitter power level are decreased by the fixed percentage.
Claim 2
Dependent Claim
162 words
A communication station for communicating with a second station in a cellular-communication network using spread spectrum modulation wherein the second station transmits power commands to the communication station based on a received power level from the communication station, the communication station comprising: a transmitter having an adjustable transmitter power level for transmitting spread-spectrum signals; means for sequentially receiving power commands from a second station with which communication is being conducted; means for comparing a sequence of at least two of the received power commands to determine if the received commands in the sequence match; and means for adjusting the transmitter power level at a same rate as the reception of the power commands by steps; wherein if the command sequence does match, a magnitude of subsequent steps in the transmitter power level are increased by a fixed percentage and if the command sequence does not match, the magnitude of subsequent steps in the transmitter power level are decreased by the fixed percentage.
