Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication that identifies one or more neighbor cells, of a set of neighbor cells, that support a service; and perform a cell reselection process based at least in part on the indication that the one or more neighbor cells support the service. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. One method of informing the UE of priorities associated with cells that support a vehicle-to-everything (V2X) service may include the UE receiving a priority indicator from the base station. The priority indicator may inform the UE of priorities associated with one or more cells that support the V2X service. The priority indicator may be received in a radio resource control (RRC) connection release message. The UE may use the priority indicator to determine which cells of the set of cells support the V2X service. Accordingly, the UE may perform a cell reselection procedure based at least in part on the priority indicator, the measured parameters, or both. By informing the UE of priorities associated with cells that support the V2X service, the V2X service may have greater continuity at the UE, thereby increasing the performance and quality of the V2X service.

Abstract: Methods and systems for performing time synchronization for a Cellular Vehicle-to-Everything (C-V2X) wireless interface of a vehicle are provided. In one example, a method comprises: determining, by a vehicle UE, whether a Global Navigation Satellite System (GNSS) receiver of the vehicle receives a GNSS signal including time information for a time synchronization operation for the vehicle's local clock source; based on whether the GNSS receiver receives a GNSS signal including the time information, adjusting a local clock time of the vehicle's local clock source based on one of: the time information included in the GNSS signal, or one or more wireless signals broadcasted from a base station; and adjusting, based on the adjusted local clock time, at least one of: a phase or a frequency of a clock signal supplied to the C-V2X wireless interface.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may detect that a vehicle-to-everything (V2X) system information block (SIB) or reconfiguration information is unavailable based at least in part on a first subscription of the first device satisfying a condition. The first device may determine the V2X SIB or reconfiguration information associated with the first subscription based at least in part on V2X SIB or reconfiguration information associated with a second subscription of the first device. The first device may perform, to one or more of a network node or a second device and using the first subscription, a V2X transmission using the V2X SIB or reconfiguration information associated with the second subscription. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information indicating a wake-up signal (WUS) configuration associated with a discontinuous reception (DRX) cycle, wherein the WU'S configuration indicates one or more WUS occasions. The UE may identify one or more conditions. The UE may refrain from monitoring at least one WUS occasion, from the one or more WUS occasions, based at least in part on the identification of the one or more conditions. The UE may monitor one or more resources during an on duration associated with the DRX cycle. Numerous other aspects are described.

Abstract: Techniques and apparatuses described herein enable a user equipment (UE) to adjust a measurement period indicated by a measurement schedule for neighbor cell measurement. For example, the UE may receive the measurement schedule. The measurement schedule may indicate a baseline measurement period. The UE may determine a measurement period (referred to as a determined measurement period) based at least in part on a received power value (such as an Srxlev) associated with the serving cell and a received power value for one or more neighbor cells.
