Abstract

A method and a base station system are specified for voice transmission via a radio interface in a digital radio communication system. In the method according to the invention, at least one signal is transmitted via a radio interface between a base station in the base station system, and a radio station. At least one characteristic value relating to the transmission response of the radio interface is determined from this signal. The characteristic value is stored in at least one storage device and is taken into account at a later point in time in addition to currently determined characteristic values for transmitter end voice and channel coding.
