  • Patent number: 10582485
    Abstract: According to one embodiment of the present invention, a method of receiving a downlink signal, which is received by a user equipment in a wireless communication system, includes the steps of receiving a TxPowerResourceConfigList for a user equipment which is not configured with a transmission mode 10 and one or more zeroTxPowerResourceConfigLists and receiving a DCI (downlink control channel) including a PRI (PDSCH RE mapping indicator).

  • Patent number: 10582412
    Abstract: A network platform manages the provisioning of a UE with a dominant identity profile and a recessive identity profile. The dominant profile is associated with a user's existing wireless data plan and the recessive profile corresponds to a data plan of a provider of device, or machine-to-machine, services to the UE. The UE uses the two profiles to transmit separate data contexts on separate respective bearers. When managing two separate bearers, the UE always uses the dominant profile first for managing a handoff to a stronger cell. The UE reports that the new cell that now serves the dominant context is the only cell that has enough strength to support the recessive context, even if other cells near the UE have signals strong enough. This necessarily causes the recessive context to always be handed off to the same cell to which the dominant context has already been handed off.

  • Patent number: 10517014
    Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

  • Patent number: 10512087
    Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

  • Patent number: 10506646
    Abstract: Embodiments produce a set of instructions for connecting to a network through a network access point based on data crowdsourced from mobile computing devices. The crowdsourced data describes interactions between the mobile computing devices and the network access point when establishing a connection to the network. A cloud service analyzes the crowdsourced data to identify a set of instructions for association with the network access point. The mobile computing devices replay the set of instructions when subsequently attempting to connect to the network access point.

  • Patent number: 10506032
    Abstract: Various embodiments are directed to systems and methods for automatically distributing loads among computing devices involved in message delivery within a group-based communication platform. Embodiments utilize a status checker to monitor the relative health and/or utilization of various channel servers each servicing a group-based communication channel for communication among a particular group of client devices. Upon detecting that one or more of the channel servers exhibit failing health characteristics, the status checker may automatically reallocate the messaging load performed by the failing channel server to other servers, thereby redefining the group-based communication channel associated with a particular group to encompass the newly assigned channel server and minimizing the impact of the failed channel server on message distribution within the group-based communication channel.

  • Patent number: 10448274
    Abstract: Systems and methods for providing Channel State Information (CSI) feedback in a cellular communications network are disclosed. In some embodiments, a base station of a cellular communications network disables inter-subframe channel interpolation of CSI-RS estimates across subframes at the wireless device and receives one or more CSI reports from the wireless device that are generated by the wireless device with inter-subframe channel interpolation of CSI-RS estimates across subframes disabled in response to the base station disabling inter-subframe channel interpolation of CSI-RS estimates across subframes at the wireless device. In this manner, CSI feedback is improved particularly in embodiments in which the base station transmits a beamformed CSI-RS resource(s) and reuses the same CSI-RS resource(s) for different beams over time.
