Abstract
A method and apparatus for uplink power control based on power spectral density are disclosed. In one embodiment, the method for use by a terminal in a satellite communication system, the terminal having an antenna, a modem and a controller, the method comprising: determining the scan and skew of the antenna; obtaining, using the controller, a value representing a maximum allowed Power Spectral Density (PSD) for the determined scan and skew; determining, using the controller, a maximum allowable modem power based on the value representing a maximum allowed PSD, where the maximum allowable modem power is that which ensures that transmissions from the terminal do not exceed the maximum allowed PSD if the maximum allowable modem output power is not exceeded by the modem; sending, using the controller, an indication of the allowable modem output power to the modem; and performing one or more transmissions from the terminal based on modem outputs in accordance with the maximum allowable modem output power.
