According to an aspect of this disclosure, a radio communication device is provided including: a first transceiver configured to transmit and receive signals in accordance with a Cellular Wide Area radio communication technology; a second transceiver configured to transmit and receive signals in accordance with a Short Range radio communication technology or a Metropolitan Area System radio communication technology; a processor configured to at least partially synchronize the receiving or transmitting of signals of the first transceiver with the receiving or transmitting of signals of the second transceiver such that at least one of at least a part of the receiving and a part of the transmitting of signals of the first transceiver and of the second transceiver is carried out at the same time.

Radio communication devices and methods for operating radio communication devices

According to an embodiments, a device may be provided. The device may include a data receiver configured to receive data in sets of consecutive packets from a data transmitter, wherein each set may include a first packet and at least one further packet. The device may further include a first packet reception determinator configured to determine whether the first packet of a set of consecutive packets is received by the data receiver. The device may further include a data sending determinator configured to determine whether the data transmitter sends the set of consecutive packets based on whether the first packet of the set of consecutive packets is received.

Data receiving devices and methods for receiving data

A transmitting and receiving arrangement as well as a method for transmission of monitoring and/or payload data in a transmitting and receiving arrangement for a wirefree communications system has a device which processes baseband for processing digital signals to form a baseband signal and a device which processes radio frequency for conversion of the baseband signal to a radio frequency signal. Monitoring and/or payload data are/is transmitted in the form of data packets via at least one channel of a channel-oriented link between the device which processes baseband and the device which processes radio frequency.

A differential clock pulse compensation is performed between the clock-pulse system () of a digital line-connected data interface and the asynchronous clock-pulse system () of a digital wireless data interface. A characteristic variable () for the asynchronous differential clock pulse between the clock-pulse systems () is monitored hereby. The data rate of the data () transmitted over the line-connected data interface is adapted depending on the characteristic variable ().

Frequency channel selection in a data transmission method uses a frequency hopping method. In a first method step, interference in a frequency channel is determined by detecting multiple erroneous transmissions in the frequency channel, and the frequency channel with interference is then eliminated from the frequency hopping sequence. In a second method step, the strength of external signals is measured within the frequency range of an eliminated frequency channel with interference, and the frequency channel is reinserted into the frequency hopping sequence if the strength is below a prescribed threshold value.

A frame structure for transmitting data over a digital interface has a plurality of data frames. In this plurality of data frames a first sampling data frame is based on at least one sampling word and dedicated to a first logical channel. A set of data frames follows the first sampling data frame and carries in a compressed format a plurality of predefined status data words dedicated at least to the first logical channel. A first further sampling data frame follows the set of data frames. It is based on at least one further sampling word and dedicated to the first logical channel.

In a method for operating a PLL frequency synthesis circuit, the circuit is in an active state and synthesizes a first output frequency during a first data transmission period. The circuit is likewise active and synthesizes a second, different output frequency during a later, second data transmission period. The PLL frequency synthesis circuit is first reprogrammed to an intermediate frequency, and is controlled from there to the second output frequency, in an intermediate time period.

Data throughput is increased in a communication system that is designed for a bidirectional information exchange between a single master terminal unit and a number of slave terminal units. For that purpose, unoccupied transmission resources of the communication channel are used, and additional addressing times are entered in a predetermined addressing schedule in which the addressing times are entered at which the master terminal unit prompts the slave terminal units for data output. The method is specifically suited for the Bluetooth standard.

In a method for avoiding transients during switching processes in integrated circuits, a module of the integrated circuit is switched from a first operating state to a second operating state, a load change occurring thereby. In this case, it is ensured that the occurring quotient of load change and time duration for the transition from the first operating state to the second operating state does not exceed a predetermined limit value, thereby reducing or avoiding transients associated with such switching.

A method for controlling antennas of a receiving device in a radio system, especially in a mobile radio system, in which at least one change is made using a frequency hopping method between a number of transmission frequencies that are provided for the transmission of radio signals. A table is formed with data relating to the reception quality of each antenna. This data is evaluated on each change to the transmission frequency, and one of the antennas is selected as a function of the result of the evaluation. The method is especially suitable for use in systems using slow frequency hopping methods (slow frequency hopping systems), such as bluetooth or WDCT systems.

In a data processing method, a remainder R that is produced during the division of an integer A by a prescribed integer B is calculated recursively. For this purpose, a data symbol word representing the integer A is decomposed into K data symbol part-words W, W, . . . , Wof word length L, and in each recursion step a function F determined by the numbers B and L is applied to an argument that depends on the function value Fobtained in the preceding recursion step, and on a data symbol part-word W.
