Abstract: The disclosure relates to a method for mitigating interference of a first radio signal received by a first transceiver of a first radio access technology (RAT) due to transmission of a second radio signal by a second transceiver of a second RAT, wherein the first transceiver and the second transceiver are physically collocated on a same device. The method includes: pre-setting a power of the second radio signal based on a throughput performance requirement for the first radio signal before transmission of the second radio signal, and tuning the power of the second radio signal during transmission of the second radio signal based on estimating the interference of the first radio signal.

Abstract: A radio communication device may be provided, including: a transceiver to exchange data with a base station; a mode determiner to determine whether to operate the radio communication device in a pre-determined mode, in which a first subset of frames of each multiframe in a plurality of multiframes is reserved for a first group of radio communication devices including the radio communication device for sending data to the base station and/or receiving data from the base station, and a second subset of frames of each multiframe in the plurality of multiframes is reserved for a second group of other radio communication devices for sending data to the base station and/or receiving data from the base station; and a measurement circuit to measure a reception quality of a pre-determined cell in the second subset if the mode determiner determines to operate the radio communication device in the pre-determined mode.

Abstract: A system and apparatus for establishing whether a received signal frame is an audio signal frame is disclosed. In one embodiment, the system includes a predetermined position in an audio signal frame containing a piece of secondary information for an audio characteristic of the audio data, with a selection device for selecting a succession of bits which is arranged at the predetermined position in the received signal frame. A decision-making device flags the received signal frame as an audio signal frame if the succession of bits represents the piece of secondary information.

Abstract: Receiver for Receiving Data Frames. According to one aspect, a receiver for receiving data frames which contain information data includes a signal input. Further, the receiver includes a data frame separator circuit for separating the signaling data from the information data. A switching device connects the data present at current input to a data output. A channel decoding circuit decodes the data which is present and generates signals which indicate whether the decoding has been carried out correctly. When correct decoding has taken place, a control circuit buffers all data and outputs a signal to the switching device to connect the buffered information data to the channel decoding circuit. When the signal indicates the correct decoding is received, the control circuit outputs the decoded information data.

Abstract: The invention relates to a method and to a device for identifying markers in data blocks. The method is characterized in that a number of data blocks (201a 201n) are received by a receiver (202) and one specific data block from the number of data blocks (201a 201n) is analyzed in order to determine whether the specific data block contains a marker (203) or not. Once a data block that contains a marker (203) is identified, a full-rate signaling block (206) that is transmitted at full rate and a half-rate signaling block (207) that is transmitted at half rate are searched for markers. A predetermined reference pattern is provided for correlation that is subsequently divided into sub-ranges that in turn are correlated with a predetermined reference pattern to identify a signaling frame in the full-rate signaling blocks (206) and/or the half-rate signaling blocks (207).

Abstract: A circuit for recording and playing back voice in digital mobile radio devices and a method for appropriately recording and playing back the voice. The circuit includes a transmit-end voice encoder, a receive-end voice decoder, a memory for the recorded signals, a further voice encoder whose output is connected to the memory, and a further voice decoder whose input is connected to the memory.

Abstract: A method for changing the execution of a program stored in a read only memory is described. For this purpose, the program has a multiplicity of program routines, and each program routine can be allocated a subprogram that is stored in a first read/write memory. In addition, each program routine has associated memory locations in a second read/write memory. If a program routine has an associated subprogram, the program routine then calls the subprogram on the basis of the content of the associated memory locations.

Abstract: A grinding tool, for attachment to a grinding tool carrier in a grinding machine, comprises a core member (3) which is provided with means such as a central bolt (5) for attachment to a tool carrier (6), and has at least two segments (21) of grinding material disposed circumferentially about and permanently fixed by an adhesive to the core member, grooves being defined between the segments of grinding material. The core member with segments of grinding material is easily replaced without replacing the tool carrier.
