  • Publication number: 20160345229
    Abstract: A receive (Rx) chain of a wireless local area network (WLAN) transceiver may be used to assist a wireless wide area network (WWAN) transceiver in a user equipment (UE). A UE may use the WLAN Rx chain to autonomously scan and measure while the UE is connected to a first or home wireless network using its WWAN transceiver. When the UE is in a connected state, the WLAN Rx chain may be used to scan and take measurements for one or more second networks operated by a second wireless operator belonging to the same mobile virtual network operator (MVNO) as the first wireless network. In another example, the WLAN Rx chain may perform a set of inter-frequency reference signal time difference (RSTD) measurements based on observed time offsets between positioning reference signals (PRSs) from neighboring cells.

  • Publication number: 20160323933
    Abstract: In a user equipment (UE) supporting multiple radio access technologies (RATs) and operating in an multiple-SIM multiple-active (MSMA) scenario, at least a portion of the wireless local area network (WLAN) transceiver may be used opportunistically to support the operation of the wireless wide area network (WWAN) transceiver to support the multiple subscriber identity modules (SIMs). For example, when a first SIM is in an active mode and using the WWAN transceiver for transmit and/or receive operations, at least a portion of the WLAN transceiver may be used in addition to the WWAN transceiver to support the WWAN operation of a second (or third, etc.) SIM. The WLAN transceiver may be used for transmit, receive, or both for the second SIM, while the first SIM continues to use the resources of the WWAN transceiver.

  • Patent number: 9479896
    Abstract: In a network node, wireless device, or both, a method for controlling activation or deactivation of a small cell activity of a portable multi-purpose wireless device in a wireless communications network may include determining a geographic location of a portable multi-purpose wireless device. The device may be capable of two or more different states of small cell activity, including an activated state, a deactivated state, or a latent state. The method may include controlling a current one of the two or more different states of the small-cell capability of the portable multi-purpose wireless device, based at least in part on the geographic location. The network node, the wireless device, or both may activate or deactivate the small cell activity, or place it into a latent state, based on additional factors. In addition to its small cell capabilities, the wireless device may perform user function unrelated to the wireless network.

  • Patent number: 9462600
    Abstract: A time period associated with each of a plurality of tasks included in a current instance of WWAN data capture/processing by a WLAN processor and a WWAN processor is determined. A total time period comprising the respective time periods of each task is compared to an overall time budget criterion to obtain a comparison outcome. A change in at least one of the tasks based on the comparison outcome is implemented. The change results in an adjustment of the total time period associated with a next instance of WWAN data capture/processing by the WLAN processor and the WWAN processor.

  • Patent number: 9374727
    Abstract: An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.
