Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) using a first radio access technology (RAT) may transmit a channel reservation preamble of a second RAT (e.g., a Wi-Fi preamble) that provides an indication to devices of the second RAT that the UE has obtained a shared channel for a channel occupancy time (COT). The UE may determine a start time of the channel reservation preamble relative to a start time of a first symbol of a transmission slot based at least in part on a time duration of the first symbol. The channel reservation preamble may reserve multiple slots or a single slot. A UE transmitting on two or more sub-channels may transmit a preamble on one of the sub-channels or on each of the sub-channels.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.

Abstract: A method, apparatus, and computer-readable medium are provided for wireless communication at a Road Side Synchronization Device (RSSD). The RSSD receives, from a first neighbor device, a first Sidelink Synchronization Signal (SLSS). The RSSD synchronizes in time/frequency with the first neighbor device, and transmits a second SLSS. The second SLSS is based on a synchronized timing and a synchronized frequency with the first neighbor device.

Abstract: Aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a peer-to-peer (P2P) communication is to be relayed based at least in part on a location of the UE and a range requirement associated with the P2P communication; and transmit the P2P communication, wherein the P2P communication includes an indication of whether the P2P communication is to be relayed. In some aspects, a UE may receive the P2P communication; determine whether to relay the P2P communication based at least in part on the indication and at least one of: a location of the UE, or a UE identifier, included in the P2P communication, that identifies the UE and is associated with a request for the UE to relay the P2P communication; and selectively relay the P2P communication based at least in part on determining whether to relay the P2P communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a service type to be used by the UE for one or more device-to-device (D2D) communications on a sidelink interface; determine a slice identifier based at least in part on the service type, wherein the slice identifier corresponds to a resource allocation to be used for the one or more D2D communications; and transmit an indication of the slice identifier. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may then be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide identifying a first set of time intervals for transmissions in a channel using a first wireless communications technology (e.g., a set of LTE-V2X intervals reserved for LTE-V2X transmissions) and a second set of time interval designated for transmissions in the channel using a second wireless communications technology (e.g., a set of DSRC intervals reserved for DSRC transmissions). A UE may determine whether one of the sets of time intervals is available for transmitting V2X messages using one wireless communications technology by performing energy detection for a threshold amount of time. The UE may then, based on the results of the energy detection, transmit the V2X message using the first wireless communication technology during a second set of time intervals or during a subsequent first set of time intervals.
