  • Publication number: 20170245102
    Abstract: It is presented a method for determining a position of a wireless device within a single radio cell served by a plurality of remote radio heads. The method is performed in a position determination node and comprises the steps of: receiving a measured power signature comprising at least two, in time separated, power measurement values of a downlink signal, the measured power signature originating from the wireless device; comparing the measured power signature with a set of reference power signatures, wherein each one of the plurality of remote radio heads is associated with a reference power signature and the reference power signatures differ for at least two of the plurality of remote radio heads; and determining a position in that the wireless device is in the vicinity of one of the at least one remote radio head whose reference power signature best matches the measured power signature.

  • Patent number: 8995396
    Abstract: A user equipment method and a user equipment in idle mode, for enabling the compilation of information concerning the radio coverage within a cell of a base station. The user equipment is configured to communicate with the base station. The method comprises the actions of detecting a loss of coverage and transmitting coverage information, to be received by the base station. A network node receives the coverage information from the idle mode user equipment. The received coverage information is identified as information related to the occurrence of lost coverage for the user equipment. Thereafter is the received coverage information logged and usable for adjusting the transmission power of the base station and/or for network planning purposes.

  • Patent number: 8934450
    Abstract: In a mobile station for use in a cellular radio system, the mobile station is adapted to increase radio measurements relating to the currently best cell at times when the user is preparing to set up a call in order to increase the likelihood that a mobile station is camping in the correct cell when setting up a call. This is obtained by adding a third mode to the already existing idle and active modes. The additional mode provides for an increased amount of idle mode measurements compared to the conventional idle mode.

  • Patent number: 8811928
    Abstract: The invention discloses a method (700) for finding differences in path loss between a plurality of RF paths between a first (120, 130) and a second (120, 130) transceiver in a wireless communications system (100). During defined 5 intervals of time (SACCH1-SACCH4), only one RF path is used to transmit from one of said transceivers to the other of said transceivers, and the receiving transceiver measures the strength of the signal received during at least a number of said intervals, thus making it possible to compare signal strength and thereby path loss between different RF paths, which in turn 10 makes it possible to find imperfections in one or more of said RF paths.

  • Patent number: 8760993
    Abstract: In a method and a transmitter data is transmitted to two mobile stations sharing the same frequency band and the same timeslot. The data is modulated using a quaternary symbol constellation. Further, the data is transmitted to two mobile stations multiplexed on a shared channel comprising two branches and the transmission power for the transmitted data is set in response to the relative gain of the two branches. Hereby, the total system interference is reduced. The method and transmitter further allows for a cellular radio system individual power control loops for the two sub-channels when the system uses MUROS.

  • Patent number: 8649284
    Abstract: A base station in a wireless network measures a total transmission power associated with calls in a cell of the wireless network, where the calls include answered calls and unanswered calls that originated in the cell. The base station further compares the measured total transmission power with a power threshold and performs at least one of the following: muting at least one of the unanswered calls downlink voice path based on the comparison, or disconnecting at least one of the unanswered calls based on the comparison.

  • Patent number: 8547842
    Abstract: In a method and a device for controlling the output power in a Base Transceiver Station adapted to transmit signals over an air interface using a power amplifier for multiple earners, the power of signals to be transmitted in an upcoming transmission time slot are added and compared to at least one threshold value. If the threshold is exceeded the output power is reduced. By implementing a power reduction scheme as set out above the risk for peak power effects is minimized at the same time as the dimensioning may be aggressive. This is made possible because no power will be backed off unless really needed.

  • Publication number: 20130163443
    Abstract: A network performs blind detection of the VAMOS capability, at or above a predetermined SCPIR level, of mobile stations. The network transmits an AQPSK modulated message having a predetermined SCPIR level on a control channel or non-traffic portion of a traffic channel, and monitors the mobile station for an anticipated action taken in response. In some embodiments, the AQPSK modulated message is repeated to increase the probability of its reception. In some embodiments, AQPSK modulated messages are transmitted at varying SCPIR levels, to determine a minimum SCPIR level at which the mobile terminal is operative in VAMOS mode. The VAMOS capability and SCPIR level of mobile stations may be recorded, so that they may later be paired for VAMOS operation.

  • Patent number: 8385958
    Abstract: In a cellular radio system data is transmitted to a Dual Carrier mobile station from two different cells during a data transfer. Hereby existing hardware in a GSM system can be utilized more efficiently. The data transmission from the two cells can be frame synchronized. Frame synchronization can for example be obtained by transmitting data from two cells located on the same radio base station site.
