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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine its position by receiving locations from one or more other UEs capable of network-based positioning. For example, a second UE may determine its location using network-based positioning and may transmit its location information to the first UE. The first UE may determine its location based on the received location information (e.g., by calculating a weighted average of different locations, by setting its location to be the same as the received location). In some cases, the first UE may receive location information from other UEs during or after a discovery process with other UEs. In some other cases, the first UE may receive messages (e.g., periodic safety messages) from the other UEs, and the messages may each include location information of the respective other UEs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring discontinuous reception on a sidelink connection between a remote user equipment (UE) and a relay UE. An example method generally includes determining a configuration for sidelink discontinuous reception (DRX) communications between the relay UE and a first remote UE, the configuration including a transmission configuration for communications from the relay UE to the first remote UE and a reception configuration for communications from the first remote UE to the relay UE; transmitting, to the first remote UE, a configuration message indicating the configuration for sidelink DRX communications between the relay UE and the first remote UE; and communicating with the first remote UE via a sidelink channel based on the configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a co-channel configuration. The co-channel configuration may indicate a set of sidelink parameters for a co-channel operation associated with dynamically utilizing sidelink radio frequency resources allocated for a first radio access technology and sidelink radio frequency resources allocated for a second radio access technology. The UE may transmit, based on the received co-channel configuration, an indication of a set of channel availability parameter values indicating an amount of available sidelink radio frequency resources associated with the first radio access technology, the second radio access technology, or both. Subsequently, the UE may receive a grant scheduling a set of sidelink resources for the wireless communication associated with the second radio access technology based on the transmitted indication of the set of channel availability parameter values for the co-channel operation.

Abstract: Certain aspects of the present disclosure are generally directed to vehicle techniques for selecting communication options for vehicle to everything (V2X) type communications. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving one or more parameters for selection of one or more features associated with one or more radio-access technology (RATs), and selecting the one or more features to be used for communicating with one or more other UEs using a V2X communication protocol. The selection of the one or more features may be based on the one or more parameters. The method may also include communicating with the one or more other UEs via the selected one or more features.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting one or more sidelink channel state information (CSI) reference signals (CSI-RSs) targeting a group of user equipments (UEs). The method generally includes requesting one or more CSI reports from a selected one or more UEs of the group of UEs. The method generally includes receiving one or more CSI reports from the selected one or more UEs.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, one or more user equipments (UEs) may implement distance-limited sidelink-based ranging techniques. An initiating UE may transmit one or more positioning reference signal (PRS) request messages to one or more target UEs via a sidelink channel. In some cases, the initiating UE may receive one or more response messages from at least one target UE that is located within a threshold distance from the initiating UE. In some examples, based on receiving the one or more response messages, the initiating UE may transmit PRSs to each target UE that transmitted a response message.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a message indicating a configuration for a first active duration for the first UE, the first active duration being for a reversed communication direction during an active duration of a first discontinuous cycle for sidelink communications. The first UE may transmit a sidelink signal to the second UE, and may activate the first time active duration during the active duration of the first discontinuous cycle. Upon activating the first active duration, the first UE may switch from a transmission mode to a reception mode, and may receive a sidelink response message from the second UE during the first active duration. Based on receiving the sidelink response message, the first UE may switch back to the transmission mode to the reception mode during the first active duration, and may terminate the first active duration.
