Abstract
Abstract A high-speed data channel (105) is set to some minimum power level and changed to a second power level after at least one good frame has been received on a reverse link dedicated control channel (DCCH). The forward data channel power level (after a good reverse link frame is received on the DCCH) is increased over a plurality of frames to a power level that differs from the forward DCCH (103) power level, and is based on a difference in the number of handoff links between the DCCH (103) and the high-speed channel (105). Power control of the data channel (105) (after achieving the second power level) is then additionally based on a time between repeats sent due to negative acknowledgments of packet data frames sent on the data channel (105).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
A method for power control within a communication system, the method comprising the steps of: assigning a remote unit a first channel; determining a power level for the first channel; determining a number of soft-handoff links for the first channel; assigning the remote unit a second channel; determining a number of soft-handoff links for the second channel; and power controlling the second channel based on a difference in the number of soft-handoff links between the first and the second channel.
Claim 2
Independent Claim
80 words
A method for power control within a communication system, the method comprising the steps of: assigning a remote unit a first channel; determining a power level for the first channel; determining a number of soft-handoff links for the first channel; assigning the remote unit a second channel; determining a number of soft-handoff links for the second channel; and power controlling the second channel based on a difference in the number of soft-handoff links between the first and the second channel.
Claim 3
Dependent Claim
49 words
The method of claim 1 wherein the step of power controlling the second channel further comprises the step of power controlling the second channel based on the power level for the first channel and the difference in the number of soft-handoff links between the first and the second channel.
Claim 4
Dependent Claim
57 words
The method of claim 1 wherein the step of power controlling the second channel further comprises the step of power controlling the second channel based on a difference in the Quality of Service (QoS) between the first and the second channels and the difference in the number of soft-handoff links between the first and the second channel.
Claim 5
Dependent Claim
49 words
The method of claim 1 wherein the step of power controlling the second channel further comprises the step of power controlling the second channel based on a frame quality of the second channel and the difference in the number of soft-handoff links between the first and the second channel.
Claim 6
Independent Claim
98 words
A method for power control of a data channel, the method comprising the steps of: assigning a remote unit a first channel; determining a power level for the first channel; determining a number of soft-handoff links for the first channel; assigning the remote unit the high-speed data channel at a power level that is based on the power level for the first channel and the number of soft-handoff links for the first channel; and power controlling the data channel based on the number of soft-handoff links for the first channel and a frame quality of the data channel.
Claim 7
Independent Claim
98 words
A method for power control of a data channel, the method comprising the steps of: assigning a remote unit a first channel; determining a power level for the first channel; determining a number of soft-handoff links for the first channel; assigning the remote unit the high-speed data channel at a power level that is based on the power level for the first channel and the number of soft-handoff links for the first channel; and power controlling the data channel based on the number of soft-handoff links for the first channel and a frame quality of the data channel.
Claim 8
Dependent Claim
33 words
The method of claim 5 wherein the step of power controlling the data channel is additionally based on a difference in a Quality of Service (QoS) between the first and the data channel.
Claim 9
Dependent Claim
67 words
The method of claim 5 wherein the step of power controlling the data channel based on the number of soft-handoff links for the first channel and a frame quality of the data channel comprises the step of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and the frame quality of the data channel.
Claim 10
Dependent Claim
84 words
The method of claim 7 wherein the step of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and the frame quality of the data channel comprises the steps of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and a time between repeats sent due to negative acknowledgments of packet data frames sent on the data channel.
Claim 11
Dependent Claim
91 words
The method of claim 7 wherein the step of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and the frame quality of the data channel comprises the steps of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and on erasure indicator bits sent on a third channel to indicate whether packet data frames sent on the data channel are erased or not erased.
Claim 12
Dependent Claim
93 words
The method of claim 7 wherein the step of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and the frame quality of the data channel comprises the steps of power controlling the data channel based on the difference in the number of soft-handoff links between the first and the second channel and on quality indicator bits sent on a third channel to indicate whether packet data frames sent on the data channel are of good quality or poor quality.
