Benefits of technology

[0012] An object of the invention is thus to specify an advantageous method or transmitter and/or receiver stations in radio communication net

Problems solved by technology

If the power used when transmitting is too great, or if an outside station transmitting on the same resource moves into the receiving area of a receiving station, this results in increased interference on various connections and in a reduction in the quality of reception in the individual connections.
What is problematic, especially with ad hoc networks, is a situation where two clusters each having one transmitting and one receiving station are moving towards each other.
In particular with clusters that are moving towards each other quickly, there is a danger that the receiving station of a clusters, as well as receive signals from its own assigned trans

Example

[0030] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0031] As can be seen from FIG. 1, clusters CL1, CL2—each made up of stations S1, R1, S3, R3 or S2, R2 communicating with each other via radio interfaces V—develop into so-called ad hoc radio networks as an example of a radio communication system. To simplify the following description, one station at a time S1 or S2 of the first or second cluster CL1, CL2 is regarded as the transmitting station S1 or S2 and a further station R1, R2 of the first or second cluster CL1, CL2 is regarded as the receiving station R1, R2. Of course, it is also possible and standard to transmit in the opposite direction. In the transmission illustrated, it is assumed that data with signaling and / or information content is transmitted by the respective transmitting station S1, S2 to ...

Abstract

In a communication system, a first transmitting station transmits a transmission signal to a first receiving station for transmitting a sequence of data via a radio interface. The radio interface is monitored with respect to an interference signal from an interference source prior to transmission via at least one of the first transmitting station and the first receiving station. The transmission only begins if the radio interface is sufficiently free from interference for a moment in time.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is based on and hereby claims priority to European Application No. 02019237.3 filed on Aug. 27, 2002, the contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a method for transmitting data in a radio communication system or a mobile transmitter and / or receiver station for such purpose. [0004] 2. Description of the Related Art [0005] In mobile communication systems, such as, for example, GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunications System), the transmitting power of the communication partner is optimized with respect to the quality of the connection. To this end, control mechanisms are used, which set the transmitting power so as to attain a desired bit error rate and / or a certain level of reception. [0006] In ad hoc networks, also referred to as self-organizing networks, several n...
