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: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices and/or the like in objects (e.g., in vehicles, machines, fixed structures, etc.) may share information acquired by one or more sensors. The disclosure relates, in some aspects, to techniques for determining that sensor information may be beneficial for one or more regions (e.g., spaces, or areas) that may be occluded to one or more types of sensing, and based at least in part on such determination(s), pro-actively sharing, or requesting sharing, of applicable sensor information, e.g., between objects comprising a user equipment (UE) and one or more sensors.

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: The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a remote user equipment (UE) may transmit, on at least one sidelink channel, a scheduling request to a relay UE connected with a network entity. The remote UE may further receive, on one or more sidelink channels, a scheduling indication including a resource grant from the relay UE in response to transmitting the scheduling request. In a further aspect, a relay UE may receive, on at least one sidelink channel, a scheduling request from a remote UE. The relay UE may further determine, a resource grant for the remote UE in response to receiving the scheduling request. The relay UE may further transmit, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.

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. A first device (e.g., a relay user equipment (UE)) may establish a communication link, where the communication includes establishing a communication link between a second device (e.g., a remote UE) and a base station, the communication link including a first communication link between the second device and the first device and a second communication link between the first device and the base station. The first device may receive, over the first communication link, a transmission corresponding to data stored at the second device. The first device may receive, over the second communication link, an indication of one or more resources for a relay transmission corresponding to the data stored at the second device. The first device may transmit, over the second communication link, the relay transmission over the one or more resources based on receiving the sidelink transmission.
