Radio frequency (RF) communication circuitry comprises an RF transceiver and conflict detection circuitry. The RF transceiver includes a first communication path configured to down-convert received RF signals using a first local oscillator (LO) receive frequency; and a second communication path configured to down-convert received RF signals using a second LO receive frequency and to operate simultaneously with the first communication path. The conflict detection circuitry is configured to determine path crosstalk using the first and second LO receive frequencies and using a first LO transmit frequency used by the first RF transceiver or a second RF transceiver to up-convert electrical signals for RF transmission, and initiate a change of the first LO receive frequency by a first frequency shift value and a change of the second LO receive frequency by a second frequency shift value in response to the path crosstalk.

Radio frequency transceiver with local oscillator control for multi-carrier applications

A baseband unit for a radio communication system based on time division multiple access includes a data processing unit configured to generate a configuration macro. The configuration macro includes information about a temporal position of a particular time slot within a time frame, wherein the particular time slot has a time duration corresponding to the total time duration of an integer number of consecutive data symbols.

Transmission unit and a method for transmitting data

This disclosure relates to radio frequency (RF) functional testing of transceivers of wireless devices.

Integrated transceiver loop back self test by amplitude modulation

The method is based on the capability for coordination of the radio activities of two mobile radio transmitting and/or receiving devices. In the case of the method, a value of at least one characteristic variable is first of all determined, which is characteristic of the requirement for coordination of the radio activity of one or both transmitting and/or receiving devices. The coordination of the radio activity of one or both transmitting and/or receiving devices is then activated or deactivated as a function of the value.

Method and apparatus for adaptive activation or deactivation of the coordination of the radio activities of two mobile-radio transmitting and/or receiving devices

A description is given of a radio frequency module comprising an interface unit configured to receive macros having a first format from an input of the radio frequency module, a microprocessor coupled to the interface unit and operable to convert the macros having the first format to macros having a second format, a first memory coupled to the microprocessor and operable to store macros having the second format provided by the microprocessor and a first finite state machine implemented in hardware and configured to process macros having the second format accessed from the first memory.

Radio frequency module

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.

Frame structure, method for organizing data and method for transmitting data

The method is based on the capability for coordination of the radio activities of two mobile radio transmitting and/or receiving devices (). In the case of the method, a value of at least one characteristic variable (P, N;) is first of all determined, which is characteristic of the requirement for coordination of the radio activity of one or both transmitting and/or receiving devices. The coordination of the radio activity of one or both transmitting and/or receiving devices is then activated or deactivated as a function of the value.
