  • Patent number: 8996041
    Abstract: Certain aspects of the present disclosure propose techniques for avoiding paging interval conflicts in a multimode terminal (MMT) capable of communicating via at least two different radio access technologies (RATs). Certain aspects provide a method for communicating, by an MMT, with first and second networks via first and second RATs. The method generally includes determining a discontinuous reception (DRX) cycle length of the first network, determining a paging cycle length of the second network, determining—based on the paging cycle length and the DRX cycle length—information associated with a position of a paging interval within the paging cycle length of the second network that avoids overlap between a paging interval of the first network and the paging interval of the second network, and communicating the information to the second network. For some aspects, the information may comprise a set of control channel cycle (CCC) indices.

  • Patent number: 8977263
    Abstract: Wireless communication in a radio access network may be implemented in a manner where a user equipment (UE) with multiple Universal Subscriber Identity Modules (USIMs) selects a system based on the system's preference status among the USIMs of the UE. A system that is home to all the UE's USIMs is selected over one that is home to some USIMs but roaming for others. A system that is home to some USIMs but not provisioned for other USIMs is selected over one that is roaming to all USIMs. A system that is roaming to all USIMs is selected over one that is roaming to some USIMs but not provisioned for other USIMs. Ranking of systems may be done independently by USIM or may be done using a combined ranking method that considers other USIMs prior to an individual USIM indicating a system priority. Manual system selection may also be used.

  • Publication number: 20150063193
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a request to receive a Multimedia Broadcast Multicast Service (MBMS) service associated with a service area identity (SAI) and a second frequency. The apparatus performs inter-frequency cell reselection from a first cell transmitting at a first frequency to a second cell transmitting at the second frequency, the second cell being an inter-frequency neighbor cell to the first cell. The apparatus receives system information from the second cell. The apparatus determines that the second cell transmitting at the second frequency is unassociated with the SAI based on the received system information. The apparatus blacklists the SAI on the second frequency in a blacklist for at least a period of time upon determining that the second cell is unassociated with the SAI.

  • Patent number: 8971348
    Abstract: To create gaps in communication activity to perform inter radio access technology (IRAT) measurement, a user equipment may isolate silent periods during voice communications. During those silent periods, instead of transmitting special bursts with erasure packets indicating silent periods, the UE may allocate the time slots that would otherwise have sent the special bursts and indicate those slots as idle so they may be used for other purposes, such as IRAT measurement.

  • Patent number: 8971955
    Abstract: Certain embodiments of the present disclosure provide a method for communicating by a multi-mode mobile station (MS) with first and second networks via first and second radio access technologies (RATs). The method generally includes measuring a time offset between frames of the first RAT and frames of the second RAT while maintaining a connection with the first network via the first RAT, sending a request to a base station of the first network to establish scan periods during which the MS may switch to the second network to monitor for paging messages, and switching to the second network to monitor for paging messages during a scan period without terminating the connection with the first network. The first RAT may comprise, for example, WiMAX, while the second RAT may comprise, for example, CDMA.

  • Publication number: 20150055626
    Abstract: Described herein are aspects related to communicating with a first radio access technology (RAT) and a second RAT, wherein a set of multi-input, multi-output (MIMO) resources is allocated for communication between a mobile station (MS) and a base station (BS) of the first RAT. A request message is sent to the BS of the first RAT requesting reallocation of at least a portion of the set of MIMO resources in a scan duration. During the scan duration, signals are received from a BS of the second RAT over a reallocated subset of the set of MIMO resources and communications occur with the BS of the first RAT over a non-reallocated subset of the set of MIMO resources. During a normal duration subsequent to the scan duration, communications occur with the BS of the first RAT using the set of MIMO resources including at least some of the reallocated subset of the set of MIMO resources.

  • Patent number: 8958324
    Abstract: Certain aspects of the present disclosure propose techniques for resolving paging interval conflicts between two different radio access technology (RAT) paging intervals and for avoiding missing paging messages for a multimode terminal (MMT). Certain aspects provide a method for detecting messages associated with paging, by an MMT supporting multiple-input multiple-output (MIMO), from first and second networks using first and second RATs, such as Time Division Synchronous Code Division Multiple Access (TD-SCDMA) and Code Division Multiple Access (CDMA) IxRTT (Radio Transmission Technology), Evolution-Data Optimized (EVDO), or Wideband CDMA (WCDMA). The method generally includes using a first MIMO receive chain of the MMT to detect a first message associated with paging from the first network and simultaneously using a second MIMO receive chain of the MMT, different from the first receive chain, to detect a second message associated with paging from the second network.
