The present invention relates to a communication device, in particular a mobile communication device such as portable radio, which is powered by a removable battery. The power supply of the communication device may be maintained by connecting an external power supply to the communication device and powering the operating elements of the communication device by the external power supply during a replacement of the battery of the communication device. In this way, an uninterrupted power supply of the communication device is achieved. Thus, no shutdown or restart of the communication device is required for replacing the batteries.

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

Described herein are devices and methods for implementing a transceiver with independently controlled components. The components may include a programmable digital portion, a dedicated digital portion, and an analog portion. Each independently controlled component includes a programmable controller that resides in the programmable digital portion of the component that controls components in the dedicated digital or analog portions using state transition information. The programmable controller is configured to accommodate a broad spectrum of state transition information and is capable of emulating a plurality of hardwired finite state machines

The invention relates to a method that includes transfer of data encoded on the basis of a first encoding scheme via an interface between a baseband assembly and a radio-frequency assembly of a mobile radio transceiver. The method further includes transfer of a data sequence which is encoded on the basis of the first encoding scheme and which identifies a change of encoding scheme from the first encoding scheme to a second encoding scheme. Lastly, the method includes transfer of data encoded on the basis of the second encoding scheme via the interface.

Transfer of encoded data

Disclosed herein are techniques, systems, and methods relating maintaining a time base between receiving and transmitting assemblies during interruption of data streams communicated therebetween.

Time-based maintenance via a packet-oriented digital interface in radio-frequency transmitting and receiving assemblies

The invention relates to a method including a step of providing a clock having a clock period, wherein an integer multiple of the clock period defines a periodic time grid. In a further step, data packets are transferred between a baseband assembly and a radio-frequency assembly, wherein the times of the start of the transfers are offset with respect to the times of the periodic time grid.

Method and device for transferring data

To support a plurality of different mobile radio standards in mobile radio terminal devices using a single system oscillator, a sampling rate converter converts the sampling rates from an input rate to an output rate and additionally outputs control information which is suitable for operating signal processing components. The components receiving the control information are arranged in the signal flow upstream of the sampling rate converter, on average exactly at a virtual sampling frequency. The virtual sampling pattern is mapped onto the frame of the physical operating clock by simply gating out edges of the physical operating clock. Using the control signal, a clock control device generates a masked clock that has, on average, an edge repetition rate which corresponds to the virtual sampling frequency of the samples or to an integer multiple thereof.

Clock control of transmission-signal processing devices in mobile radio terminal devices

A discrete sampling control signal, which influences the sampling time, from a sampling phase selection element is calibrated by definition of quantization intervals for a sampling time error signal. For this purpose, a received signal is shifted through a series of time shifts &#x3c4;in the signal path upstream of the sampling phase selection element. The sampling time errors eassociated with the respective time shifts &#x3c4;are measured. The quantization steps of the sampling control signal that are suitable for the sampling phase selection element are then determined from the relationship obtained between &#x3c4;and e.

A mobile station has an apparatus by means of which the power consumption of the mobile station is controlled. The apparatus has a monitoring unit which is connected to the at least two radio systems in the mobile station. During activity pauses in the mobile station, whose time duration and whose start and end times are monitored by the monitoring unit, radio system units which are not required, and possibly further units in the mobile station, are deactivated or are switched to a state with reduced power consumption.

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.

A mobile station is provided comprising a transmission and reception unit and an identification module that can be inserted into the mobile station. The mobile station provides a user, in the standby mode, with services and/or data records that can be retrieved by the user. To prevent unauthorized access to the services and/or data records, each service and/or data record is assigned a characteristic access identifier that is activated or deactivated by inputting and/or transmitting an associated security code. For the purpose of inputting and/or transmitting the security code, the mobile station comprises a security component. Depending on the state of the access identifier, whether activated or deactivated, access to a service and/or data record in the standby mode on the mobile station is disabled or enabled, respectively.
