  • Publication number: 20230096036
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a service-based cell reselection by a user equipment (UE) in a wireless communication system. The UE may have a service relationship with a particular service. A wireless communication system may provide different types of services via different radio frequencies. The UE may determine which cells to measure for cell reselection to include those that correspond to a service of interest to the UE. In addition to power savings, the UE may experience faster cell reselection for a service. The techniques of this disclosure also may enable a priority-based cell reselection so that the UE can camp on a cell that supports a higher priority service compared to other services supported by the UE.

  • Publication number: 20230057143
    Abstract: A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

  • Patent number: 11533623
    Abstract: Apparatus, methods, and computer-readable media for facilitating detection of false base stations based on signal times of arrival are disclosed herein. An example method for wireless communication of a UE includes receiving a signal from each of one or more neighboring base stations. The example method also includes determining a system timing associated with the wireless communications network based on a respective time of arrival at which each signal is received from the neighboring base stations. The example method also includes receiving a signal from an FBS, the FBS signal being associated with a PCI different than the PCIs associated with the signals received from each of the neighboring base stations. Additionally, the example method includes identifying a presence of the FBS based on a difference between the system timing and a time of arrival at which the signal is received from the FBS.

  • Publication number: 20220330153
    Abstract: Methods, systems, and devices for wireless communication are described related to a duty cycle configuration for power saving. A user equipment (UE) may receive control signaling indicating a duty cycle for cycling between a first power state associated with a first configuration and a second power state associated with a second configuration. In some examples, the first and second configurations may indicate a bandwidth part (BWP) configuration, restricted reception or transmission of one or more channels within the BWP configuration, or both for the UE. The UE may communicate first data traffic in accordance with the first configuration while operating in the first power state. The UE may transition from the first power state to the second power state in accordance with the duty cycle. The UE may communicate second data traffic in accordance with the second configuration while operating in the second power state.
