  • Patent number: 11902847
    Abstract: A computing device is described for performing local interference avoidance, when supporting concurrent voice and data transmissions, and with access to multiple radios. The computing device predicts when coexistence issues will occur from maintaining independent voice and data transmissions using separate radios. To avoid local interference issues, the computing device automatically switches to operating a different combination of radios, making local interference less likely to occur. In some cases, the computing device may consolidate the voice and non-voice data exchanges to occur using a single radio. In some cases, rather than consolidation, the computing device may move the voice or the non-voice data exchange to a different radio as a way to avoid the local interference.

    Abstract: The present invention relates to a group (G1, G2) of at least two transceiver units (1, 2; 3, 4) in at least one wireless communication system. The transceiver units (1, 2; 3, 4) in the group (G1, G2) are arranged for wireless communication with at least one other transceiver unit. The transceiver units (1, 2; 3, 4) in the group (G1, G2) are arranged to transmit signals with polarizations that are essentially parallel to each other when received by at least one transceiver unit for which the transmitted signals (5, 6) constitutes interference. The present invention also relates to a method, a node and a transceiver unit.

  • Patent number: 9585069
    Abstract: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.

  • Patent number: 9507009
    Abstract: Assisted global positioning system (AGPS) information is retrieved from mobile devices and employed to facilitate antenna location. Measurement information, including AGPS information, can be received from a plurality of mobile devices dispersed over a geographical region. The measurement information can include location and timing information for the plurality of mobile devices. A timing difference between co-located antennas of a base station associated with the plurality of mobile devices can be computed. The location of the co-located antennas can be determined based on evaluating errors resultant from estimations based on a plurality of test locations. The measurement information can be aggregated over time and can be employed to update the antenna locations.

  • Patent number: 9497766
    Abstract: In order to configure a communication device connected to a wireless network including N communication channels, the communication device being adapted for communicating via one communication channel at a time, means of selection of a channel from amongst the N communication channels enables: selecting a communication channel with an unknown disturbance level, when the disturbance level of at least one communication channel is unknown; and otherwise selecting the least disturbed communication channel. Dynamic configuration means include means for reactivating the selection means in case of disturbances representing unsatisfactory transmission conditions on the selected communication channel according to a predetermined criterion. The dynamic configuration means are deactivated when the selection means have been reactivated N times.

  • Patent number: 9369915
    Abstract: An inter-system interference estimation method is disclosed for both primary and secondary radio systems. In the case of a primary system (such as a GSM system), inter-system interference estimation is based on a comparison of cell level measurement statistics before and after secondary spectrum usage in neighboring cells. In the case of a secondary system (such as an LTE system), inter-system interference estimation is based on a measurement on secondary spectrum before starting transmission on the secondary spectrum. Based on both of the above mentioned inter-system inter-cell interference estimations, a cell-level decision on the secondary spectrum usage is made, and optimization of radio resource allocation inside the systems may be carried out.

  • Patent number: 9326255
    Abstract: Disclosed in the present invention are a method, an apparatus and a system for interference management. In the embodiments of the present invention, a Home NodeB (HNB) registers in a macro cell in advance, so that a NodeB Controller (NBC) knows the information of a potential interference source HNB beforehand. Thus simply through a normal measurement and a report subsequently performed by a terminal, an interference source HNB can be found easily, and an interference management of the interference source HNB also can be performed. The solution can avoid the situation in the prior art that the interference management is performed necessarily with a cell identity of the interference source HNB obtained by the terminal. With the application of the solution, the interference management to the HNB can be performed timely and effectively and the interference experienced by the terminal from the HNB is reduced.

  • Patent number: 9301304
    Abstract: A radio base station and a method therein are provided for determining where in a cell a UE, being served by the radio base station, is located. The method includes receiving at least a first and subsequently a second Reference Signal Received Power (RSRP) value from the UE, and comparing the received first and second RSRP values. The method further includes selecting a first threshold value based on the comparison indicating increasing RSRP values corresponding to the UE moving towards a cell-center area, or selecting a second threshold value based on the comparison indicating decreasing RSRP values corresponding to the UE moving towards a cell-edge area. Further, the method includes determining whether the UE is located in the cell-center area or the cell-edge area using the selected threshold value.

  • Patent number: 9246556
    Abstract: A radio network control method that allows uplink signals transmitted by a mobile station to be received by two or more selected base station radio systems and then combined, thus providing receiver diversity. The method requires measurement of radio link qualities of the OFDM signals passing between mobile station and base station radio system. The method is selectively applied to individual mobile stations and for each mobile station to a selection from the available base station radio systems—the selection being based upon the relative and/or absolute measurements of radio link qualities.

    Abstract: During scheduled or unscheduled wireless communication outage, restoration of crucial or critical cell site devices and/or base station device are prioritized. The system filters current key performance indicator values and historical key performance indicator values for a reference cell device to produce a filtered key performance indicator metric for the reference cell device, filters statistical data to produce filtered statistical data representing a filtered statistic for the reference cell device, determines a weighting factor for the reference cell device, and displays of a ranking score determined as a function of the weighting factor, the filtered statistic data, and the filtered key performance indicator metric. The ranking score provides an ordering that can be used to restore critical cell site devices and/or base station devices.
