Abstract: A method for collision avoidance between a vulnerable road user transportation vehicle and a surrounding transportation vehicle. The user of the vulnerable road user transportation vehicle makes use of a portable communication device. Since such vulnerable road users are often involved in accidents since they are not easily recognized in the traffic, the disclosure increases safety for these vulnerable road users. The method includes transferring position detecting sensor data or derived position data of the vulnerable road user transportation vehicle to the portable communication device which performs a map matching technique for refining the position data and transfers the refined position data to the vulnerable road user transportation vehicle. The vulnerable road user transportation vehicle distributes the refined position data to the surrounding transportation vehicles which calculate a trajectory for the vulnerable road user transportation vehicle and estimate the risk of a collision.

Abstract: A method for adjusting the interference level for a wireless communication from a first mobile station to a second mobile station including detecting an interference level at a transmitting station and providing for elevation of the direction of beam for the signal transmissions from the first mobile station to the second mobile station relative to an angle between the ground plane and the current direction of beam for the transmissions from the first mobile station to the second mobile station. Such lifting up of the beam avoids interference at the place of a third mobile station located at the direction of signal transmission but with further distance, since the signal strength then vanishes relatively quickly if the beam is lifted up.

Abstract: Modern mobile communication systems transfer data by error protection measures including the use of a forward error correction code for the channel coding and a HARQ (hybrid automatic repeat request) system for the repeated transfer of incorrect transport blocks in response to the error protection mechanisms failing. When a turbo code is used as an error protection code, two decoders work on the decoding of the turbo code. Disclosed is an expanded HARQ system wherein the receiving side determines which of the decoders was more greatly challenged in the decoding of the turbo code and reports this to the transmitting side. Instead of uniformly providing more redundancy data to both decoders, more redundancy data are targetedly provided to the more greatly challenged decoder in the expanded HARQ process than in the case of the repetition operation according to the typical HARQ process reducing the latency of the data transfer.

Abstract: A method for data communication between communication participants including observing the surroundings of the transmitting participant, determining the positon and motion of the communication participants, and estimating the transmission conditions at a later point in time. The solution is based on classifying the data for data communication in different categories, the categories determining susceptibility of the data to transmission errors determining which data is transmitted under good transmission conditions only and which data is be transmitted under rough transmission conditions whereby the transmission station plans the transmission of data in different categories. The method further includes selecting for data transmission at a given time for which the transmission conditions have been estimated so the data to be transmitted is in a category fitting to the estimated transmission conditions based on the categories data, and transmitting the selected data.

Abstract: A method for the digital transmission of data blocks from a transmitting station to a receiving station, wherein delta information is generated at the transmitting end which indicates the positions at which a further data block differs from the preceding data block. The delta information is provided with error protection and is added to the further data block and is transmitted. The received first and the at least one extended further data block are stored in the receiving station.

It is thereby made comparable with the at least one further data block. A soft combining of the received further data block and the transformed preceding data block is then carried out. The payload of the further data block is retrieved from the combined data block.
