  • Patent number: 11375449
    Abstract: Systems, apparatuses, and methods are described for determining locations for range-extending devices. Signal strength between devices within an area may be measured one or more times over a time period. Based on the measurements, signal loss over fronthaul links and backhaul links may be determined for each range-extending device in the area. A predicted improvement in signal quality may be determined. A direction and distance to move each range-extending device may be determined based on a comparison with the fronthaul and backhaul signal qualities and the predicted improvement in signal quality. The direction, improvement in signal quality, and/or user preferences for devices may be used to determine an improvement associated with moving one or more range-extending devices.

  • Patent number: 11375485
    Abstract: The present invention pertains to a terminal device, which, when ARQ is used for communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, and when a transmission mode that supports up to 2 TB in a PCell is set in the terminal, is capable of reducing the amount of signaling from a base station while eliminating a lack of PUCCH resources when semi-permanent scheduling (SPS) is used in the PCell. A control unit in this device selects one value among values obtained by adding 1 to four PUCCH resource indexes, which have been preset for PUCCH resource 1 by the base station, on the basis of values for transmission power control information (TPC command for PUCCH) in a PDCCH, for which notification has been received at the start of SPS.

  • Patent number: 11349745
    Abstract: Latency of a gateway system that connects to downstream services can be measured using an external computer system. The gateway may route component requests to various downstream services in order to service a main request, and be part of an overall service where low latency is important. It may be desirable for the gateway system to have as little added latency as possible. Benchmarking the gateway by performing latency measurements can give an indication of how the gateway is performing. If software on the gateway changes, re-benchmarking the gateway can reveal if problematic code was introduced. A measurement system can employ a lightweight process so that minimal additional latency is incurred by the measuring process. Memory can be allocated as to avoid a garbage collection process so that the latency measurement is unaffected when garbage collection occurs, for example, and multiple buffers can measure latency for different request types.

  • Patent number: 11337171
    Abstract: A set of neighboring base stations coordinate to transmit a cell-specific common resynchronization signal via a Common Synchronization Channel (CSCH). At least one neighboring base station transmits the cell-specific common resynchronization signal by a timing advance value before a serving base station transmits the cell-specific common resynchronization signal. A user equipment (UE) device receives the cell-specific common resynchronization signals from the base stations and combines the received cell-specific common resynchronization signals. In some examples, the UE device coherently combines the received cell-specific common resynchronization signals. Once the received signal strength of the combined received cell-specific common resynchronization signals exceeds a threshold level, the UE device utilizes the combined received cell-specific common resynchronization signals to obtain resynchronization.
