Abstract: Aspects relate cross-pool resource reservations of resources for sidelink-positioning reference signals (SL-PRS). A wireless communication device can transmit a first SL-PRS resource reservation message within resources in a SL communication resource pool. The first SL-PRS resource reservation message may identify a first SL-PRS resource within a SL-PRS resource pool. The wireless communication device can also transmit a first SL-PRS in the first SL-PRS resource within the SL-PRS resource pool. The wireless communication device can also receive a second SL-PRS resource reservation message within resources in the SL communication resource pool. The second SL-PRS resource reservation message may identify a second SL-PRS resource within the SL-PRS resource pool. The wireless communication device may then receive a second SL-PRS in second SL-PRS resource within the SL-PRS resource pool. The SL communication resource pool may be different from the SL-PRS resource pool.

Abstract: Techniques described herein leverage existing localization sensors or V2X devices to detect one or more other vehicles that include wireless systems that can interfere with in-vehicle wireless networks. The localization sensors or V2X devices can provide information to determine a location, a heading, a speed, a size, and a type of other vehicles. This information can be used to determine a probability of network interference and allow the in-vehicle wireless networks to employ one or more techniques to mitigate the effects of the interference. The interference mitigation techniques can include increasing or decreasing transmitter power, changing a frequency or a channel of a wireless transmitter, or activating one or more additional transmitters as relays to improve reliability.

Abstract: Techniques disclosed provide for enhanced V2X communications by defining information Elements (IE) for V2X messaging between V2X entities. For a transmitting vehicle that sends a V2X message to a receiving vehicle, these IEs are indicative of a detected vehicle model type detected by the transmitting vehicle of a detected vehicle; a pitch rate of the transmitting vehicle, a detected vehicle, or a detected object; a roll rate of the transmitting vehicle, a detected vehicle, or a detected object; a yaw rate of a detected vehicle, or a detected object; a pitch rate confidence; a roll rate confidence; an indication of whether a rear brake light of a detected vehicle is on; or an indication of whether a turning signal of a detected vehicle is on; or any combination thereof. With this information, the receiving vehicle is able to make more intelligent maneuvers than otherwise available through traditional V2X messaging.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for the configuration and operation of a multi-hop relay at different layers to enable a remote user equipment (UE) to act as a relay for a client UE that may be out of coverage of a network. For example, a network relay UE may establish a communication link with the network, and the network relay UE may transmit, to a remote UE, a relay configuration that authorizes the remote UE as a multi-hop relay to provide a connection to the network for one or more other UEs. The remote UE may transmit an acknowledgement to the network relay UE in response to receiving the relay configuration, and the remote UE may then transmit a relay discovery message including multi-hop relay information based on receiving the relay configuration.

Abstract: Certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes determining a configuration associated with sidelink for at least one communication; monitoring for at least one SCI after entering a sidelink discontinuous reception (DRX) on phase based on the configuration; receiving, from one or more other UEs, the at least one SCI during the sidelink DRX on phase for at least one communication; and determining an extension to the sidelink DRX on phase based on the at least one SCI scheduling at least one first resource for one or more transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may receive an indication of a session key from an initiator UE in a sidelink communications system, from a network entity (e.g., a base station), or the like. In some cases, the target UE may also receive an indication of a nonce in a message of a PRS procedure. The target UE may select a positioning reference signal (PRS) sequence for the PRS procedure using the session key and optionally the nonce, such as by using a defined function at the target UE with the session key and the nonce as an input. Once the target UE selects the PRS sequence, the target UE may encode the PRS sequence and may transmit the PRS sequence to the initiator UE.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: Certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes determining one or more sidelink discontinuous reception (DRX) configurations associated with at least a communication on a sidelink, determining a wake up indication configuration associated with the one or more sidelink DRX configurations, monitoring for at least one wake up indication from at least one other UE based on the wake up indication configuration, the at least one wake up indication indicating a sidelink DRX on phase associated with the sidelink DRX configuration, deciding an action for the sidelink DRX on phase based on the at least one wake up indication for the at least one communication on the sidelink, and performing the action in accordance with the decision.

Abstract: Embodiments include methods performed by a processor of a wireless device for discontinuous reception. The processor may monitor for sidelink control signaling from a base station using a radio of the wireless device during a sidelink control signaling monitoring duration. The processor may receive sidelink control signaling that allocates a sidelink communication resource and schedules a sidelink communication. The processor may perform the scheduled sidelink communication based on the received sidelink control signaling. The processor may place the radio of the wireless device into a low power mode outside of the sidelink control signaling monitoring duration when no sidelink communication is scheduled.
