Abstract
Abstract A communication system (200) includes a plurality of channel elements (201-05). A mobile station (101) communicates with a base station (114), both included in communication system (200), via a forward link (121) and a reverse link (122) communication. The communication system assigns a finite number (N) of channel elements (201-03) selected from plurality of channel elements (201-05) for forward link communication (121), inputs at least one forward link signal (210) associated with forward link (121) to each of N channel elements (201-03), determines a power gain requirement of forward link (121), adjusts power gain setting of each of N channel elements (201-03) such that an aggregate of power gain settings of N channel elements (201-03) substantially equals to the power gain requirement, outputs N forward link signals (231-33) with adjusted power gain accordingly, and combines N forward link signals (231-33) to form a combined forward link signal (250).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
153 words
In a communication system that includes a base station having a plurality of channel elements, a method for communicating between a mobile station and said base station comprising the steps of: assigning a finite number (N) of channel elements selected from said plurality of channel elements for a forward link communication from said base station to said mobile station; inputting at least one forward link signal associated with said forward link communication to each of said N channel elements; determining a power gain requirement of said forward link communication; adjusting power gain setting of each of said N channel elements such that an aggregate of power gain settings of said N channel elements substantially equals to said power gain requirement; outputting N forward link signals with adjusted power gain according to said adjusting step from correspondingly said N channel elements; combining said N forward link signals to form a combined forward link signal.
Claim 2
Dependent Claim
153 words
In a communication system that includes a base station having a plurality of channel elements, a method for communicating between a mobile station and said base station comprising the steps of: assigning a finite number (N) of channel elements selected from said plurality of channel elements for a forward link communication from said base station to said mobile station; inputting at least one forward link signal associated with said forward link communication to each of said N channel elements; determining a power gain requirement of said forward link communication; adjusting power gain setting of each of said N channel elements such that an aggregate of power gain settings of said N channel elements substantially equals to said power gain requirement; outputting N forward link signals with adjusted power gain according to said adjusting step from correspondingly said N channel elements; combining said N forward link signals to form a combined forward link signal.
Claim 3
Dependent Claim
48 words

Dependent Claim
61 words
The method as recited in claim 1 further comprising the steps of: determining power level adjustment of a reverse-link signal from said mobile station; selecting a first channel element from said N channel elements to add at least one power level control data bit having a value according to said determining step to information data transmitted via said forward link signal.
Claim 8
Dependent Claim
63 words
The method as recited in claim 6 further comprising the steps of: detecting failure of said selected first channel element; substituting a second channel element selected from said N channel elements excluding said first channel element to add at least said power level control data bit having a value according to said determining step to information data transmitted via said forward link signal.
