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.

Claims (20)

1. A method for transmitting a sequence of data in a radio communication system, comprising:

checking a radio interface for an interference signal of an interference source, by at least one of a first transmitting station and a first receiving station, to detect an approach of the interference source relative to the first receiving station;

determining according to a first threshold a maximum possible transmission duration for interference free transmission of the sequence of data, based on at least one of an expected change in intensity of the interference signal and an expected change in intensity of a transmission signal;

after said checking, generating a transmission signal at the first transmitting station for transmitting the sequence of data to the first receiving station via the radio interface during a length of time not exceeding the maximum possible transmission duration for interference free transmission; and

at least one of determining and estimating a second threshold value for a minimum required difference between the intensity of the transmission signal and the intensity of the interference signal as a measurement for a non-interfering signal that does not interfere with the transmission signal.

2. A method according to claim 1 , further comprising determining a decoding area around the first receiving station within which the interference signal of the interference source causes unacceptable interference.

3. A method according to claim 2 , further comprising exchanging, between the first receiving station and the first transmitting station, parameters at least one of relating to a corresponding station, determined in the corresponding station and relating to transmission conditions.

4. A method according to claim 2 , further comprising locating, by the first receiving station, a usual interference source within a detection area based on a determinable velocity of the first receiving station and a transmitted velocity of the interference sources within the detection area of the first receiving station.

5. A method according to claim 3 , wherein said exchanging exchanges at least one of the first threshold value and the maximum possible transmission duration.

6. A method according to claim 3 , wherein at least one of a usually maximum possible and maximal sensible velocity is used for the stations and interference sources for which no velocity information is available, at least one of within and outside a detection area of the first receiving station.

7. A method according to claim 1 , further comprising one of determining and estimating an expected increase in intensity of the interference signal at the first receiving station using at least one of actual and maximum possible relative velocity of the interference source and the first receiving station to each other.

8. A method according to claim 1 , further comprising one of determining and estimating an expected increase in intensity of the interference signal at the first receiving station as a function of at least one of the actual and maximum possible relative velocity of the first transmitting station and of the first receiving station to each other.

9. A station for transmitting a sequence of data in a radio communication system with mobile stations and mobile interference sources, comprising:

a memory; and

one or more processing devices configured to execute:

checking a radio interface for an interference signal of an interference source by at least one of the mobile stations to detect an approach of a mobile interference source relative to a mobile station;

determining according to a first threshold a maximum possible transmission duration for interference free transmission of the sequence of data, based on at least one of an expected change in intensity of the interference signal and an expected change in intensity of the transmission signal;

after said checking, generating a transmission signal at rhea first transmitting mobile station for transmitting the sequence of data to rhea first receiving mobile station via the radio interface during a length of time not exceeding the maximum possible transmission duration for interference free transmission; and

at least one of determining and estimating a second threshold value for a minimum required difference between the intensity of the transmission signal and the intensity of the interference signal as a measurement for a non-interfering signal that does not interfere with the transmission signal.

10. A station according to claim 9 , wherein a transmitting mobile station not involved in the intended transmission of the sequence of data is a mobile interference source.
