AUTONOMOUS SATELLITE AUTOMATIC GAIN CONTROL
First Claim
1. A method for processing communication signals in a return path of a satellite, the method comprising:
- receiving, via an antenna coupled to the return path, a number of data signals on a single frequency channel, wherein each of the number of data signals occupies a unique time-frequency sub-channel of the single frequency channel, originates from a corresponding one of a number of user terminals (UTs), and includes a plurality of time slots dynamically allocated to a group of user equipment (UE) devices associated with the corresponding UT;
determining a combined power level of all the number of received data signals that occupy all the time-frequency sub-channels of the single frequency channel; and
adjusting an amplifier gain applied to the number of received data signals in the return path based, at least in part, on the combined power level.

Abstract
A method and apparatus for addressing reductions in the uplink path gain associated with user terminals are disclosed. A return path of the satellite may receive a number of data signals on a single frequency channel, wherein each of the number of data signals occupies a unique time-frequency sub-channel of the single frequency channel, originates from a corresponding one of a number of user terminals (UTs), and includes a plurality of time slots dynamically allocated to a group of user equipment (UE) devices associated with the corresponding UT. The return path may determine a combined power level of all the number of received data signals that occupy all the time-frequency sub-channels of the single frequency channel, and then adjust an amplifier gain applied to the number of received data signals in the return path based, at least in part, on the combined power level.

10. A satellite, comprising:
-
an antenna configured to receive a number of data signals on a single frequency channel, wherein each of the number of data signals occupies a unique time-frequency sub-channel of the single frequency channel, originates from a corresponding one of a number of user terminals (UTs), and includes a plurality of time slots dynamically allocated to a group of user equipment (UE) devices associated with the corresponding UT; one or more processors; and a memory configured to store instructions that, when executed by the one or more processors, causes a return path of the satellite to; determine a combined power level of all the number of received data signals that occupy all the time-frequency sub-channels of the single frequency channel; and adjust an amplifier gain applied to the number of received data signals in the return path based, at least in part, on the combined power level. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
