Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first set of synchronization signals from a first synchronization source and may receive a second set synchronization signals from a second synchronization source, where the UE determines a first priority for the first synchronization source based on a first identification (ID) associated with the first set of synchronization signals and a second priority for the second synchronization source based on a second ID associated with the second set of synchronization signals. Accordingly, the UE may then select the first synchronization source or the second synchronization source based on which synchronization source has a higher priority and communicate with the selected synchronization source (e.g., via sidelink communications).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a device-to-device communication with another UE, a modulation and coding scheme (MCS) configuration, of a set of MCS configurations, based at least in part on at least one of a transmission mode, a packet characteristic, a mobility state of the UE, a capability of the UE, a transmission mode of the device-to-device communication, a received indication from the other UE, or a combination thereof. The UE may transmit, to the other UE, data using an MCS selected based at least in part on the MCS configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.

Abstract: Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a wireless in-vehicle network (wIVN) capability indication that indicates that the UE is associated with a vehicle that includes a wIVN; receive a response to the wIVN capability indication from another UE; and provide configuration information to a wIVN control unit of the vehicle associated with configuring the wIVN based at least in part on the response. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) such as a vehicle may identify data for transmission and transmit a request message to one or more receiving UEs (e.g., other vehicles). The request message may be associated with a first priority. The transmitting UE may monitor resources for a response message. The response message may be associated with a second priority. If the transmitting UE receives a response message, the transmitting UE may determine whether to transmit the data based on a comparison of the priorities of the request message and the response message. In some cases, the transmitting UE may transmit the data if the transmitting UE does not receive any response message. A receiving UE may receive the request message and determine whether to transmit a response message based on the priority and/or the receive power of the request message.

Abstract: Aspects relate to mechanisms for a base station to provide sidelink synchronization assistance to a plurality of user equipment (UEs). The base station may be configured to identify a detection time window that includes a sidelink synchronization resource configured for transmission of a sidelink synchronization signal on a sidelink carrier. The base station may further be configured to transmit an indication of the detection time window to the plurality UEs on a cellular carrier to enable the UEs to detect a sidelink synchronization signal on the sidelink carrier within the detection time window and synchronize communication on the sidelink carrier.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication. The apparatus receives data traffic from an application layer and assigns at least one Quality of Service (QoS) flow identifier (ID) for the data traffic based on radio resources information for the data traffic. The data packets for transmission with different radio resources are assigned different QoS flow IDs.

Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Abstract: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.
