摘要： The invention relates to a method of automatic gain control (AGC) in a base station of a cellular radio network and to a network part in a cellular radio network. The method comprises receiving at least one random access burst transmitted by a subscriber terminal of the cellular radio network on a random access channel. Then the received power of the random access burst is measured, followed by generating subscriber terminal-specific AGC data on the basis of the received power of at least one random access burst. Then, subscriber terminal-specific AGC data is stored. Next, a normal burst transmitted by the subscriber terminal on a stand-alone dedicated control channel is received, and the gain of the normal burst received is controlled by the subscriber terminal-specific AGC data. Finally, the controlled normal burst is subjected to analog-to-digital conversion.
