摘要： A user terminal (100, 200, 300, 400), a UE, for a wireless communications system. The UE comprises an antenna unit (130) and a receiver unit (125) for receiving signals on a radio channel within the system. The UE also comprises a sensor (115) for sensing the position of the UE and for generating an output signal indicative of said position. The UE further comprises an evaluation unit (120) which is arranged to measure the UE's communication performance over the channel and to also receive the output signal from the sensor and to generate a first control signal (S1) which indicates if altering the position of at least part of the UE, and thereby the position of the UE's antenna unit (130), will result in an increased communication performance over the channel for the UE.

摘要： A method and an arrangement enables an efficient radio resources utilization in a communication network system comprising a communication network node communicating with one or more user equipments over a radio interface on uplink and downlink channels. The user equipment provides the communication network node with information about a power shortage problem in the user equipment by using a pre-determined field, such as the E-TFCI field, of the uplink channel, whereby the communication network node is allowed to take a pre-determined action regarding available radio resources.

摘要： In a method and device, simple hardware such as a standard User Equipment (UE), a mobile telephone, is used to collect the impulse response of a radio channel. The data generated is used to classify radio channels based on the impulse response estimates by estimating distribution parameters of the impulse response. This makes it possible to distinguish between different types of fading and hence, radio environments by matching the parameters to known radio channel models.

摘要： The present invention relates to a method to identify one or more interference sources in a mobile radio system, preferably in a GSM radio network for mobile telephones. A received signal (r) consists of a wanted signal and a number of interference signals of which one is a dominating interference signal and where all signals includes a known training sequence (TK1,TK2, . . . ). The carrier is estimated and subtracted from the received signal (r) giving a remaining interference signal (s).This signal is correlated against known training sequences (TKj, j=0,1,2, . . . ,7) resulting in a training sequence associated with the interfering signal. According to the invention, the identification code (BCC) of a possible interference source (BS1) from said training sequence is determined. After that, a number of candidates (CA1,CA2, ), each corresponding with a certain cell from the identification code (BCC) are determined and also the frequency which is disturbed and the timing offset (t1,t2, . . . FIG. 7) for the frequencies used by said candidates. Finally it is investigated if one or more (fa,fb) of these have the same time offset as the interference signal (t0) resulting in that at least one candidate (CA3) with the best matching offsets on its frequencies is identified as the interference source.
