    Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may monitor various sensors to obtain data associated with a user of the first UE, and may determine that the user is in a vulnerable state based on monitoring these sensors. The vulnerable state of the user may include an inebriated state, a distracted state, an impaired state, or a disabled state, among other examples. After detecting the vulnerable state of the user, the first UE may transmit a public safety message (PSM) to other devices in the area. Upon receiving the PSM from the UE, a network entity may use positioning information to identify other UEs within a threshold distance of the first UE, and may transmit an alert message to these UEs. The techniques described herein may reduce the probability of nearby pedestrians or vehicles colliding with the user.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first safety message associated with the UE. The first safety message may be transmitted according to a first periodicity of a set of transmission periodicities for safety message transmissions. The UE may select a second periodicity of the set of transmission periodicities based on one or more environmental conditions associated with the UE. The UE may transmit a second safety message associated with the UE according to the second periodicity of the set of transmission periodicities based at least in part on selecting the second periodicity. The one or more environmental conditions may include topological information, road information, or visibility information. The UE may select the second periodicity based on one or more parameters associated with the UE.

    Abstract: Aspects relate to sidelink positioning using second stage sidelink control information (SCI-2). A first wireless communication device (e.g., first UE) may transmit SCI-2 including a sidelink positioning establishment message to establish a sidelink positioning session with at least a second wireless communication device (e.g., a second UE). Each of the first UE and second UE may then transmit positioning reference signals (PRSs) and generate and transmit sidelink positioning information based on the PRSs during the sidelink positioning session. The sidelink positioning information may further be transmitted via SCI-2.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a sidelink connection with a second UE, where the sidelink connection is associated with a plurality of flows. The first UE may determine, based on monitoring each flow of the plurality of flows, a radio link status of the sidelink connection. The first UE may transmit, based on the determining, a non-access stratum layer message to the second UE based at least on the radio link status of the sidelink connection.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may communicate with a second UE using a shared radio frequency spectrum band. The first UE may perform a listen before talk (LBT) and may transmit a first positioning reference signal (PRS) based on a result of the LBT. The first UE may transmit the first PRS using a first time resource that is based on a duration of the first PRS. In response to detecting the first PRS, the second UE may transmit a second PRS using a second time resource that is based on the duration of the first PRS. The second UE may transmit the second PRS based on performing an LBT without a random back-off, which may enable the second UE to transmit the second PRS with reduced latency and improved reliability.

    Abstract: Methods, systems, and devices for wireless communication are described. An initiator user equipment (UE) may broadcast, via a sidelink connection to a set of target UEs, a group sidelink communication request that includes a sidelink ranging service identifier. The group sidelink communication request may further include a broadcast identifier or a groupcast identifier. The initiator UE may establish, via the sidelink connection, a set of unicast sidelink sessions with the set of target UEs. some examples, the initiator UE may transmit, via the sidelink connection, a set of position reference signal requests via the set of unicast sidelink sessions to initiate a set of sidelink ranging sessions. The initiator UE may then receive, via the sidelink connection, a set of position reference signal responses from the set of target UEs during each of the plurality of sidelink ranging sessions.
