Abstract: This disclosure relates to techniques for configuring, performing, and reporting neighbor cell measurements in a wireless communication system. A base station of a serving cell may provide configuration information relevant to performing layer 1 (L1) measurements based on reference signals of one or more neighbor cells. A UE may perform L1 inter-frequency measurements of the neighbor cell(s) based on the configuration. The UE may report the measurements.

Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

Abstract: Technology for a Next Generation NodeB (gNB) operable to communicate over an anchor channel for Unlicensed Internet of Things (U-IoT) is disclosed. The gNB can encode control information for transmission on two discovery reference signal (DRS) subframes to a user equipment (UE). The control information can be transmitted on an anchor channel having a set frequency for U-IoT in an adaptive frequency hopping system. The control information can include: a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) transmission, and a system information block for MulteFire bandwidth reduced (SIB-MF-BR).

Abstract: A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.

Abstract: Provided is a method for a user equipment (UE). The method comprises determining a first time period for the UE, based on whether the UE uses Discontinuous Reception (DRX) and whether the UE uses Measurement Gap (MG). The first time period indicates a respective timing criterion for the UE to determine a time period of maintaining available downlink timing for a reference cell; The method further comprises determining, based on the first time period, a first time threshold for the UE to determine reference cell availability.

Abstract: Techniques are provided for Wake up signal monitoring in a radio resource control connected (RRC) mode. An example method can include a user equipment (UE) determining capability information associated with wake-up signal (WUS) monitoring, the capability information to include an indication that the UE supports WUS monitoring in a radio resource control (RRC) connected mode. The UE can transmit, to a base station, an indication of the capability. The UE can perform, while in a sleep state in which transmitting and receiving by a main radio is suspended, WUS monitoring to detect a trigger. The UE can transition from the sleep state to the awake state based on the trigger. The UE can monitor for a downlink (DL) transmission in the awake state.

Abstract: The present disclosure is related to techniques for configuring a repeater device by control signaling in a wireless communications system. In some embodiments, a repeater device is configured to form separate coverage regions. For example, the repeater device determines a first coverage region based on a first beam at the repeater device paired with a network device, wherein the first coverage region corresponds to a direction such that the first beam falls within the first coverage region for serving a control link or a backhaul link between the repeater device and the network device. Based on a first indication, the repeater device determines one or more coverage regions with respect to the first coverage region, wherein the one or more coverage regions are configured to communicate with a user equipment via an access link of the repeater device.
