Circuit arrangement and method for attenuation compensation in an antenna signal link

A circuit arrangement for compensating for an attenuation occurring in an antenna signal link between a mobile radio terminal and an antenna, comprising:

• at least one antenna signal amplifier in the antenna signal link for amplifying or attenuating an antenna signal;
• a control unit associated with said at least one antenna amplifier for adjusting a gain factor by which the antenna signal conducted through the at least one signal amplifier is amplified or attenuated;
• and
• a circuit arrangement having at least one detection unit for detecting an antenna signal power of the antenna signal in a signal path of the antenna signal link, wherein
• the control unit is configured for changing the gain factor,
• for detecting a change, following as response to a change of the gain factor, of antenna signal power caused by a change of transmit power of a mobile radio terminal, and
• for adapting the gain factor to a coupling attenuation of the antenna signal link in dependence on a detected response of the mobile radio terminal.
