  • Patent number: 9998876
    Abstract: Determining a location of a user equipment (UE) based on historical location data and historical sector transition data is disclosed. A correlation between historic location information and a historic sector transition can be determined. The correlation can be stored in a searchable data set. A location of a current UE can be inferred based on a sector transition of the current UE. The sector transition of the current UE can be searched against eh data set to indicate a likely location of the current UE based on historical information. The searchable data set can be based on sparse location data enabling location determinations for a current UE that can otherwise lack location services. Moreover, an order of a sector transition can imbue a directionality to stored location information such that a likely location in a sector can be correlated to a transition from a prior sector of a network session of the UE.

    Abstract: Systems and methods relating to non-adaptive beam scanning in a wireless network are disclosed. In some embodiments, a method of operation of a transmit node to perform non-adaptive beam scanning for transmit beam patterns of the transmit node that partition a service coverage area of the transmit node into transmit partition cells is provided. The method transmitting a known signal using each of multiple scanning beam patterns for each of multiple beam scanning stages over non-overlapping radio resource slots. The scanning beam patterns for the beam scanning stages are such that each unique combination of scanning beam patterns consisting of one scanning beam pattern from each of the beam scanning stages corresponds to a different transmit beam pattern of the transmit node. This multi-stage beam scanning approach provides an exponentially more efficient process for beam scanning than the conventional Sequential Beam Sweeping (SBS) approach.

    Abstract: A wireless communication device (WCD) stores a location of a portable WAP and is configured to report the stored location of the portable WAP to a location-based service provider (LBSP) when the WCD is within coverage of the portable WAP and requests a location-based service from the LBSP. While the WCD is within coverage of the portable WAP, the WCD (i) uses a wireless-communication interface to detect that the WCD is also within one or more particular cellular coverage areas and (ii) stores a correlation between the portable WAP and the one or more particular cellular coverage areas. Thereafter, while the WCD is again within coverage of the portable WAP, the WCD determines that the WCD is not within coverage of the one or more particular cellular coverage areas. In response, the WCD reconfigures itself to not report the stored location of the portable WAP to the LBSP when the WCD requests the location-based service.

  • Patent number: 9888368
    Abstract: An Internet Protocol Multimedia Subsystem (IMS) network uses the Session Initiation Protocol (SIP) to provide communication services to mobile nodes. A short message service gateway (SMS-GW) in the IMS network receives a request to deliver a message to a mobile node. The SMS-GW determines whether the mobile node is IMS registered. If the mobile node is IMS registered, the SMS-GW may transmit a SIP MESSAGE request to a call session control function (CSCF) serving the mobile node in order to deliver the message to the mobile node. If the mobile node is SIP-capable but is not IMS registered, the SMS-GW may instead transmit a SIP MESSAGE request to the mobile node's IP address. To obtain the mobile node's IP address, the SMS-GW may query a domain name server (DNS) that stores associations between hostnames and IP addresses of mobile nodes.

  • Patent number: 9883494
    Abstract: A method and apparatus for transmitting control information are discussed. The method can include generating uplink control information (UCI) and transmitting the UCI through an physical uplink control channel (PUCCH) in a subframe, wherein when the subframe is configured for transmission of a scheduling request (SR) and when transmission of a hybrid automatic repeat request (HARD)-acknowledgement (ACK) coincides with the subframe, transmission power of the PUCCH is determined based on a number of HARQ-ACK information bits and a SR bit. A value of the SR bit can be determined by whether or not the subframe is configured for a scheduling request.

  • Patent number: 9867145
    Abstract: Channel estimation accuracy is improved by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel allocated to the same receiver. The physical control channel may be a DPCCH, E-DPCCH or other type of physical control channel allocated to a receiver for facilitating uplink or downlink communication. In one embodiment, control channel symbols are transmitted for use in channel estimation by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a physical data channel allocated to the receiver (200). Control channel symbols are transmitted to the receiver over the physical control channel at the adjusted power level (202). The receiver uses the control channel symbols to perform channel estimation (204).
