Abstract
Abstract Power control in a spread-spectrum communication system takes place by receiving a signal from a remote unit (713) at both a first (701) and a second (707) base station and combining the two received signals to form a single combined signal. The power of the remote unit (713) is adjusted based on the single combined signal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A method for power control in a communication system, the method comprising the steps of: receiving at a first base station, a first signal transmitted by a remote unit; receiving at a second base station a second signal transmitted by the remote unit; combining the first and the second signals to produce combined signals; and adjusting a power of the remote unit based on the combined signals, wherein the step of adjusting the power of the remote unit comprises the steps of utilizing a best quality frame information received from one of the first and the second base stations transmitting the best quality frame information to the first and second base station to produce a transmitted best quality frame information, and adjusting a power of the remote unit based on the transmitted best quality frame information.
Claim 2
Independent Claim
136 words
A method for power control in a communication system, the method comprising the steps of: receiving at a first base station, a first signal transmitted by a remote unit; receiving at a second base station a second signal transmitted by the remote unit; combining the first and the second signals to produce combined signals; and adjusting a power of the remote unit based on the combined signals, wherein the step of adjusting the power of the remote unit comprises the steps of utilizing a best quality frame information received from one of the first and the second base stations transmitting the best quality frame information to the first and second base station to produce a transmitted best quality frame information, and adjusting a power of the remote unit based on the transmitted best quality frame information.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein the communication system comprises a code-division, multiple-access communication system.
Claim 4
Dependent Claim
50 words
The method of claim 1 further comprising the steps of: receiving by the first base station the best quality frame information to produce a received best quality frame information; storing the received best quality frame information in a filter; and determining an amount of poor-quality frames existing within the filter.
