The application relates to the management of measurements for the minimization of drive tests MDT. In particular it relates to the measurement of uplink parameters such as UL Coverage Optimization, QoS Verification, or IP Throughput by an entity of the radio access network such as a NodeB or a RNC. In the past, the MDT configuration was always passed on to one or more UEs being served by the particular eNB. Consequently, only downlink parameters could be measured and collected in the past in the scope of MDT. Now, the eNB itself has to perform certain measurements (pertaining to UL traffic), and to combine the results of this eNB based measurements later on with the results reported by the UE over the Uu air interface. Therefore, the application proposes a new parameter in MDT Configuration, which is received from the EM, to turn on/off MDT Uplink Measurements. The trace-based MDT configuration received from the EM (1202) is split into two parts (1204), whereby the new parameter is processed on the CN/RAN side for performing the requested UL measurements, while the rest of the MDT configuration parameters is sent over the air interface to the respective UE (1206). Furthermore, it proposes to combine the MDT UL measurements performed in the RNC/NB/eNB itself and the measurements collected by the UE in a single trace-base MDT report (1212).

Abstract
One embodiment of the present invention relates to a method for improving the power consumption of a transmission chain by varying the operating point of a power amplifier to optimize (e.g., reduce) the current that is consumed by the amplifier. The operating point is varied by changing the bias voltage(s) (e.g., supply voltage, quiescent voltage) of the amplifier to a predetermined value that is chosen based upon the effect that a given transmitted signal modulation scheme characteristic (e.g., channel bandwidth and/or number of subcarriers) has on the operating point of a power amplifier. For example, if the characteristics indicate a good power amplifier performance the linear output power capability of a power amplifier can be lowered, by changing the bias voltage(s) supplied to the power amplifier, to reduce the output power capability and current consumption of the power amplifier.

The method of signalling system information includes broadcasting a piece of system information in a radio cell, the piece of system information indicating that a first portion of a frequency spectrum, the frequency spectrum being available for the radio cell, is assigned to a first radio mode, the piece of system information further indicating that a second portion of the frequency spectrum is assigned to a second radio mode, the second radio mode being different from the first radio mode. A radio base station is configured to perform the method of signalling system information. A radio communication terminal is configured to receive the broadcasted piece of system information.

Abstract
In an embodiment, a method for determining the type of a mobile radio base station is provided. The method may include receiving a synchronization message comprising a mobile radio base station identifier, and determining the type of a mobile radio base station using a previously signaled and stored piece of mobile radio base station type determining information indicating a rule as to how the type of a mobile radio base station out of a plurality of types of a mobile radio base station can be derived from a mobile radio base station identifier and the received mobile radio base station identifier.

Abstract
A method and mobile communication device that reduce communication interruption time when a base station stops operating are described. The mobile communication device is wirelessly connected to a cell operated by a base station. The method includes determining a fallback cell, obtaining parameters to quickly establish a wireless connection to the fallback cell, determining that the base station is stopping operation, and using the parameters to quickly establish a wireless connection to the fallback cell. Also described are a base station and method for the base station to reduce communication interruption time. The method includes determining that the base station is stopping operation, switching to a backup power source if the base station is stopping operation due to loss of power, and transmitting a message to the mobile communication devices connected to the base station that they should switch to a fallback cell, since the base station is stopping operation.
