  • Radio receiver control in high speed scenario
    Patent number: 10469111
    Abstract: A wireless communication device detects when the wireless communication device is in a high speed environment, e.g., on a high speed train, and detects whether the behavior of the automatic frequency control (AFC) shall be changed since the AFC behavior is not stable. Receiver algorithms, i.e., the AFC, are changed such that an optimization for the high speed environment is obtained, without any risk of degrading the performance in all other fading environments.

  • Flexible Selection of Timing Advance Control Method for Supplementary Uplink Connections
    Publication number: 20190313356
    Abstract: Exemplary embodiments include methods adjusting transmission timing of a wireless communication device (UE) operating in a network comprising first and second base stations (BS). The methods include determining a first allowable timing adjustment range corresponding to an uplink (UL) connection between the UE and the first BS. The methods include determining a second allowable timing adjustment range corresponding to a supplementary uplink (SUL) connection between the UE and the second BS, wherein the SUL connection is not associated with a DL connection between the UE and the second BS. The methods include determining if a single timing advance (TA) value can be used to adjust the UEs transmission timing to satisfy both the first and second ranges, and performing a corrective action if it is determined that said single TA value cannot be used. Embodiments also include first and second BS, and UEs, configured to perform various aspects of the exemplary methods.

  • Thresholds for radio link monitoring with advanced receivers
    Patent number: 10333683
    Abstract: Different Out-of-sync thresholds are defined for Radio Link Monitoring by a UE having a selectively enabled advanced receiver feature. When the advanced receiver feature is disabled, the UE monitors received signal quality and compares a signal quality metric to a first threshold developed for a reference receiver. When the advanced receiver feature is enabled, the UE compares the signal quality metric to a second threshold indicating lower signal quality than the first threshold. In either case, if the signal quality meets the respective threshold, the UE goes Out-of-sync. The Out-of-sync UE continues to monitor received signal quality. Regardless of whether the advanced receiver feature is enabled or not, a third threshold, developed for the reference receiver, is applied to determine when to return to In-sync. In one embodiment, the reference receiver enables two antennas, and the advanced receiver feature is enabling four antennas.
