Abstract

Abstract The invention relates to a method for measuring the condition of a receiving antenna of a base station in a TDMA radio system, in which TDMA channel structures according to ETSI/GSM recommendation 05.02 are used, by means of test measurements performed in predetermined TDMA time slots. According to the invention, the test measurements are performed, without disturbing the normal operation of the base station and without allocating a traffic channel, during time slots of an IDLE frame of a channel structure TCH/F+SACCH/TF and/or during time slots of an IDLE frame of a channel structure SDCCH/8 according to the ETSI/GSM recommendation 05.02.
