  • Publication number: 20140140223
    Abstract: A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.

  • Patent number: 8730915
    Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

  • Publication number: 20140119343
    Abstract: A user equipment capable of communicating on multiple radio access technologies (RATs) may receive conflicting paging occasions for each RAT. That is, the paging occasions may occur at sufficiently overlapping times such that a user equipment may not dedicate all its receive resources to each paging occasion. In such instances, a user equipment may divide receive resources among the RATs to receive pages even in the face of paging occasion conflicts.

  • Publication number: 20140086076
    Abstract: A user equipment (UE) dynamically adjusts a decoding time to accommodate a delay associated with decoding a high-speed shared control channel (HS-SCCH) to avoid wasting idle time slots that would otherwise be deemed busy time slots. The UE determines a dynamic protection line that extends beyond a last time slot of a subframe. The dynamic protection line is calculated based on an amount of time to complete the processing and decoding of a control information. This dynamic protection line provides a dynamically determined delay for decoding the HS-SCCH.

  • Publication number: 20140071939
    Abstract: A user equipment (UE) may reduce reselection delays when the UE is in the idle mode. In such instances, the UE adaptively adjusts a cell reselection timer based at least in part on the availability of a downlink time slot resource. The adjustment of the cell reselection timer may be based at least in part on the availability of the downlink time slot resources. The cell reselection timer is adjusted (e.g., shortened or scaled down) when the downlink time slot resources are unavailable to the UE.

  • Patent number: 8670330
    Abstract: Methods and apparatus are provided for performing measurement of reference signals in the proper subframes of a first radio access technology (RAT) while operating in a second RAT. For certain aspects, the first and second RATs may be Time Division Duplex Long Term Evolution (TDD-LTE) and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), respectively. By knowing the correct TDD-LTE downlink and uplink subframe configurations, a user equipment device (UE) may temporarily leave the TD-SCDMA network during an idle interval and perform expedited and accurate measurement of TDD-LTE reference signals without errors from trying to measure reference signals during uplink subframes.

  • Publication number: 20140056217
    Abstract: A user equipment (UE) may scale down a signal strength of a radio access technology (RAT) cell in a report to a serving cell to avoid multiple connection attempts to the same radio access technology cell. The UE may initiate a predefined timer, called a target cell timer, on which the scaling down of the reported signal strength of the particular RAT cell is based. The timer is initiated when the UE returns back to the serving cell after failure to access a top ranked RAT neighbor cell.
