The invention relates to a method for transmitting in a time multiplex radio communication system, for instance, a GSM-type mobile telephony system, different commands from a movable station to a fixed station with respect to the selection of transmitter antenna in the fixed station. Each transmission sequence from the movable station includes a synchronizing word which consists of a predetermined number of binary bits. The different commands are transmitted by using different synchronizing words in dependence on the command to be transmitted. The movable station has access to at least two different synchronizing words. The synchronizing words used in addition to a standard synchronizing word are formed by the binary bits from the standard synchronizing word being shifted laterally to mutually different extents and/or in mutually different directions in order to generate different, new synchronizing words. In this way, there is formed in the receiver of the fixed station an impulse response having a pulse which occurs at different time points depending on which synchronizing word was used by the movable station.
A method for transmitting, from a movable station to a fixed station in a time multiplex radio communication system, different commands concerning a selection of transmitter antenna in the fixed station, wherein the commands are transmitted in transmission sequences and each transmission sequence from the movable station includes a synchronizing word consisting of a predetermined number of binary bits, the method comprising the steps of:
A method for transmitting in a time multiplex radio communication system different commands from at least one movable station to a fixed station, each transmission sequence from said mobile station having a standard synchronizing word including a predetermined number of binary bits, comprising:
