The invention relates to a position-adaptive communication method which is carried out by a communication control module of a movable vehicle () in order to establish and maintain a communication connection () between the vehicle () and an opposite station (). The communication method is a packet-based communication method, and a transmission pause () is provided between data packets and/or within the data packets. Position data of the vehicle () relative to a global coordinate system is ascertained, and a movement data set is received from at least one opposite station by means of a receiving device. Position data is extracted from the received movement data, and the position of the opposite station in the global coordinate system is determined. A directional vector () from the vehicle () to the opposite station () is ascertained, and a signal propagation time is ascertained from the length of the directional vector (). The transmission path () is then adaptively matched to the ascertained signal propagation time by a timer of the communication control module.

Position-adaptive communication method

The invention relates to a direction-based interface selection method, carried out by a communication control module () in a vehicle (), for establishing and retaining a wireless high-frequency communication connection between a communication interface of a moving vehicle () and a communication interface of at least one counterpart station. In this case, position data and an orientation of the vehicle with respect to a global coordinate system are determined. A position data record is determined by at least one counterpart station and the position data () contained therein are extracted. A direction vector () from the vehicle () to the counterpart station is then determined and an assignment to a sectoral radiation characteristic of a transmission apparatus is determined for said vector. This transmission apparatus is then connected to a communication device () via a communication position switch ().

Direction-based interface selection method

In a method for wireless communication, a receiver receives a first signal at a first radio frequency and determines the reception level of the first signal. The receiver receives data during a reception level of the first signal at the first radio frequency. The receiver decides, based on the determined reception level, whether at least one measurement is to be taken on a second signal transmitted at a second radio frequency. A radio station carries out the method.

According to the method for transmission of organizational information to at the least two communication systems in a channel via a radio interface, the channel transmitting in a targeted manner and the transmitted organizational information is chosen depending on the direction of the transmission.

In a method for establishment of a connection in a radio communication system, a user terminal selects an operator, based on information on at least one operator of a radio communication system in a country-specific pilot channel, selects a radio communication system based on information on at least one radio communication system in an operator-specific pilot channel for the selected operator and carries out an access to the selected radio communication system for establishment of a connection.

A method of selecting suitable frequency bands for data transmission between a network node and a user equipment within a mobile communications network. A method selects suitable frequency bands for data transmission between a network node and user equipment within a mobile communications network. A scheduler on the network node side selects data transmission mode depending on the user equipment capability of receiving data from at least two frequency bands simultaneously. The scheduler preferably selects the data transmission mode in the following way: simultaneous data transmission over at least two frequency with or without splitting traffic data or data transmission over only one available frequency band. For data transmission, a radio frame structure (Big MAC element) is dynamically established in the so-called medium access control layer, shortened so-called MAC-layer, by using concurrent radio resources from other frequency bands or other radio access technologies.

A number of subscriber stations use a random access channel in an uncoordinated manner and transmit signals in the channel at a transmission power level which is set on the basis of a random principle. Deterministic transmission power level control is replaced by stochastic transmission power level control. For repeated transmission from two subscriber stations, it is improbable that both will once again transmit at the same transmission power level. If collisions occur between two transmissions which do not now have the same received power level at the base station, then, providing the power level difference is sufficient, at least the more powerful signal can be evaluated (capture effect) and only the transmission of the weaker power level signal need be repeated. Thus, on average, this reduces the delay before successful reception of the transmissions.

Stochastic transmission power level adjustment in a random access channel in a radio communications system and method

A method for control of the transmission power of a transmitting station in a radio communication system, whereby a receiving station receives data packets from the transmitting station, the receiving station receives anew incorrect received data packets from the transmitting station and the transmission power of the transmitting station is controlled depending on a repetition rate of the data packets received anew by the receiving station.

A method transmits packet data in a communications system between a transmitter and a receiver. One potential goal is to ensure correct processing of such packet data. To this end, the packet data are repeatedly transmitted by the transmitter and are received by the receiver as data received earlier or data received later. A diversity combination of the data received earlier and the data received later is performed to reconstruct the transmitted data packet.

Method or communications system using a robust diversity combination

A method for controlling transmit power for connections between a base station and mobile stations of a radio communications system includes the steps of designating a direction of transmissions from mobile stations to a base station as an upward direction, and designating a direction of transmissions from the base station to the mobile stations as a downward direction. Information is transmitted to the mobile stations in the downward direction simultaneously in one frequency channel. Received powers are determined at at least two of the mobile stations. A dynamic range of transmit powers for the frequency channel is set. Transmit powers for the base station are determined. The determined transmit powers are mobile-station-specific by taking the received powers into account. A minimum transmit power is at least equal to a maximum transmit power minus the dynamic range. A device for controlling the transmit power is also provided.
