  • Patent number: 9497745
    Abstract: Systems and methods that provide a virtual macro cell in a heterogeneous cellular communications network are disclosed. In general, micro cells served by multiple micro base stations are aggregated to provide a virtual macro cell. Each micro base station provides service to one or more low mobility user equipments (LMUs) located within the micro cell of the micro base station using one or more first resources (e.g., a first carrier) that are allocated to LMUs. In addition, each micro base station cooperates with the other micro base station(s) in the virtual macro cell to provide service to one or more high mobility user equipments (HMUs) located within the virtual macro cell using one or more second resources (e.g., a second carrier) that are allocated to HMUs. By utilizing the virtual macro cell for HMUs, handover and paging overhead are reduced for the heterogeneous cellular communications network.

    Abstract: A method is provided for controlling measurements in a wireless telecommunications terminal. In a Long Term Evolution (LTE) wireless communication system, the network instructs a UE to measure the received power and quality of the reference signals of the serving cell as well as of neighbor cells. The object of improving the system power consumption of user equipment (UE) that has to perform such measurements is solved by distributing the measurement functionality between RRC and PHY layers such that the RRC layer is enabled to rest in a power save mode unless results of the measurements have to be reported to the network, and to be only active for a minimum to ensure that the UE still behaves standard compliant to the network.

  • Patent number: 9008695
    Abstract: Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.

  • Patent number: 8995995
    Abstract: A system and method for automatically roaming with a wireless device. A signal strength of a first wireless signal is sampled at a time interval. A determination is made whether the signal strength is less than a threshold for a predetermined duration. The wireless device is set to roam on a second wireless signal in response to the signal strength of the first wireless signal being less than the threshold for the predetermined duration. The wireless device is reset to a default setting for communication after a predetermined duration.

    Abstract: Systems, methods, and device for adjusting an operation time of a radio link failure timer are disclosed herein. User equipment (UE) may be configured to communicatively couple to an evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE use different radio link failure timer parameters depending on the speed of the UE. The radio link failure timer may run for a longer time for rapidly moving UEs and run for a shorter time for slowly moving UEs. In an embodiment, the UE may scale the radio link failure timer by a scaling factor. In another embodiment, the UE may include multiple radio link failure timers for different speeds. The radio link failure timer parameters for each speed may be specified by the E-UTRAN in a one-to-one communication. The E-UTRAN may determine which parameters to use for each UE based on characteristics of the UE.
