  • Patent number: 10009854
    Abstract: Embodiments of a communication station and method for transmission power control for Time-of-Flight (ToF) measurements in a wireless network are generally described herein. A protocol for fine timing measurements (FTMs) optimizes location performance rather than Wi-Fi coverage area and bit error rate by limiting an allowed maximum power and hence, EVM. A user equipment (UE) comprises a transceiver configured to receive, from an initiating station, a fine timing measurement request (FTMR) message at a maximum transmit power and lowest modulation and coding scheme (MCS), measure a relative received signal strength (RSSI) for the received FTMR message, determine a maximum transmit power, where the maximum transmit power is proportional to the measured RSSI; and transmit, to the initiating station, a fine timing measurement 1 (FTM1) message at the determined maximum transmit power and received lowest MCS.

  • Patent number: 9980243
    Abstract: Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available.
