Secondary link power control in a wireless communication network
First Claim
1. A method of reverse link power control at a mobile station comprising:
- transmitting a pilot signal at a controlled transmit power from the mobile station to one or more remote transceivers;
transmitting one or more traffic channel signals from the mobile station at one or more power gains directly or indirectly relative to the transmit power of the pilot signal; and
adjusting the power gain of one or more of the traffic channel signals responsive to receiving reception quality feedback from the one or more remote transceivers for the one or more traffic channel signals.

Abstract
A communication transceiver transmits a power-controlled first signal responsive to received power control commands and transmits one or more additional signals at variable power gains relative to the transmit power of the first signal based on reception quality feedback received for the additional signals. Thus, a mobile station may transmit a traffic channel at a variable power gain relative to its pilot signal power and vary that gain responsive to reception quality feedback received by it for the traffic signal. Of course, the mobile station may float more than one traffic channel using variable gains and may use different variable gains for each one. Further, the mobile station may float one or more non-pilot channels relative to the pilot or relative to another channel, while transmitting one or more fixed gain channels. Similar variable power gain may be employed at network base stations for forward link signals.

14. A mobile station comprising:
-
transceiver circuits configured to transmit and receive signals to and from a wireless communication network, said signals including a pilot signal transmitted from the mobile station at a controlled transmit power and one or more traffic channel signals transmitted at one or more power gains directly or indirectly relative to the transmit power of the pilot signal; and one or more processing circuits operatively associated with the transceiver circuits, said one or more processing circuits including a power control circuit configured to adjust the power gains of one or more of the traffic channel signals responsive to receiving reception quality feedback from one or more remote transceivers, such that relative transmit powers of one or more traffic channels transmitted by the mobile station vary as a function of receiving the reception quality feedback. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
