1. An apparatus for gain control in a communication system, the apparatus comprising:
- means for receiving at least one aggregate communications signal, the at least one aggregate communications signal comprising a summation of distributed communications signals;
means for detecting at least a sample of a signal level of the at least one aggregate communications signal; and
means for attenuating the signal level of the at least one aggregate communications signal based on the signal level sample.

15. A program product comprising program instructions, embodied on a storage medium, that are operable to cause at least one programmable processor included in one or more controllers within a communication system, the system having gain control for signals from distributed antennas, to:
-
receive a plurality of communications signals, the plurality of communications signals comprising a summation of prior-summed communications signals from at least one of a plurality of downstream antenna ports in a daisy chain distribution, with one of the plurality of communications signals being a final aggregate signal;
detect at least a sample of a signal level of the final aggregate signal;
generate a feedback attenuation signal based on the detected sample;
generate attenuation instructions based on the feedback attenuation signal; and
attenuate each of the plurality of communications signals in response to the signal levels of the final aggregate signal and the feedback attenuation signal. - View Dependent Claims (16, 17, 18, 19, 20)
