Abstract: Aspects relate to techniques for efficient sidelink resource reservation based on the congestion on a sidelink. A wireless communication device may transmit control information indicating a number of resources reserved for an initial transmission and at least one retransmission of a packet. In some examples, the number of resources included in the control information can be either three resources or two resources based on the congestion. For example, the number of resources included in the control information can be three resources in response to a congestion value representing the congestion on the sidelink being less than a threshold. In addition, the number of resources included in the control information can be two resources in response to the congestion value being greater than or equal to the threshold.

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: Methods, systems, and devices for wireless communications are described. Generally, the user equipment (UE) may adjust an operational mode of a circuit of the UE by selecting one or more parameters (e.g., power level or clock frequency or both). Adjusting parameter values may result in avoiding increased temperature. The UE may set an operational mode of a circuit based on a determination or a prediction of a number of blind decodes to be performed, a number of pending receive packets, or a number of transmitting UEs from which the UE will receive traffic. The UE may efficiently reduce unnecessary power expenditures and decrease temperature.

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, a semi-persistent scheduling (SPS) configuration associated with the UE. Additionally, the UE may refrain from transmitting a control element within an uplink period, associated with the SPS configuration, when a buffer of data intended for the base station is empty. For example, the UE may increase a period associated with the control element. Additionally, or alternatively, the UE may randomly select the control element, to refrain from transmitting, from a plurality of control elements within a period of time. 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.

Abstract: Certain aspects of the present disclosure provide techniques for collision mitigation in sidelink. A method that may be performed by a user equipment (UE) includes measuring channel busy ratio (CBR), estimating a number of UEs using the channel, estimating a congestion level based on the CBR and the estimated number of UEs. A method that may be performed by a sidelink UE includes determining a semi-persistent scheduling (SPS) resource reservation including first subframes, determining second subframes for generated packet transmission, determining to skip transmission in the second subframes, listening during the second subframes for another sidelink UE’s transmission, and determining whether to reselect resources. Another method includes listening during a first subframe for another sidelink UE’s transmission, detecting the transmission collides with a scheduled transmission resource for the sidelink UE based on an amount of frequency resource overlap, and determining to reselect resources.
