Abstract
A method for transmitting signaling is proposed which is simple and efficient without taking up significant transmission capacity. In the method, a transmission of the signaling takes place between a mobile station (12) and a base station (11) in a mobile radio network. The signaling is transmitted in at least one predetermined time slot (301), and a different signaling is assigned to each mobile station (12) disposed in a radio cell of the base station (11), so that signaling operations of various mobile stations, transmitted via the at least predetermined time slot, can be distinguished from one another in the base station (11).
Claims15
A method for transmitting signaling between a mobile station (12) and a base station (11) in a mobile radio network, characterized in that the signaling is transmitted in at least one predetermined time slot (301), and each mobile station (12) disposed in a radio cell of the base station (11) is assigned a different signaling, so that signaling operations of various mobile stations transmitted via the at least one predetermined time slot can be distinguished from one another in the base station (11).
The method of one of the foregoing claims, characterized in that the signaling operations are transmitting with a power that is substantially lower than the power for transmitting useful data.
The method of one of the foregoing claims, characterized in that at least one of the signaling operations is transmitted together with another signaling or with useful data of an already existing connection in the at least one predetermined time slot (301).
The method of one of the foregoing claims, characterized in that the mobile radio network is operated by a CDMA-TDD process (CDMA=Code Division Multiple Access;
- TDD=Time Division Duplex), using orthogonal codes.
The method of one of the foregoing claims, characterized in that with the signaling, a request for a transmission channel for setting up a connection between the mobile station (12) and the base station (11) is transmitted.
The method of one of the foregoing claims, characterized in that with the signaling, a command for regulating the transmission power is transmitted.
The method of one of the foregoing claims, characterized in that with the signaling, a reference signal for a channel estimation is transmitted.
