Abstract: Methods, systems, and devices for wireless communication are described to support security techniques for ranging in wireless networks. A first device may transmit an indication to initiate a ranging procedure with a second device, and in response to the indication, the second device may transmit signaling to the first device and to one or more third devices. The first device and the one or more third devices may each determine a respective location metric associated with the second device based on the signaling. The one or more third devices may each transmit, to the first device, the respective location metric. Based on the communicated location metric(s), the first device may determine whether an eavesdropper is present and may communicate with the second device based on the determination.

Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for determining a Zone identifier (ID), Zone Center, and negative acknowledgement (NACK) ranges. Included are operations and means at a receiving user equipment (UE) to determine a current geographic location (GLL) of the receiving UE, and select a Zone ID based on a two-dimensional (2-D) lookup into an indexed array with the current GLL, the indexed array storing Zone data for one or more geographic Zones. The Zone data for each geographic Zone may be indexed according to geographic position, and include a Zone ID, Zone center, and one or more NACK ranges, each NACK range corresponding with a geographic Zone disposed about the geographic Zone corresponding to the Zone ID. Operations further include performing a NACK operation based on the selected Zone ID and a NACK range.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support vehicle alerting, such as in autonomous driving networks. Vehicle alerting may provide messages alerting other vehicles and/or network components to instances of autonomous driving disengagement. A vehicle operating according to an autonomous vehicle (AV) mode may transmit an over-the-air message to one or more other devices, such as nodes of an autonomous driving network, to alert the one or more devices to the vehicle disengaging the AV mode. A device receiving an autonomous disengagement message may alter one or more autonomous operation aspects in response to the over-the-air message. Other aspects and features are also claimed and described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may communicate with a network entity via a relay UE using one or more radio resource control (RRC) messages that are encapsulated in a dedicated sidelink signaling message directed to the relay UE. The UE may receive, from the network entity via the one or more RRC messages, an access stratum configuration for a sidelink unicast link between the remote UE and the relay UE. The UE may configure the sidelink unicast link based at least in part on the received access stratum configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may transmit a sidelink request to a second UE. The sidelink request may indicate a set or a segment of the data resources. A second UE may transmit a positive sidelink response indicating that the set or the segment of resources is available for reservation, or may refrain from transmitting a positive sidelink response if the set or the segment of the data resources is unavailable for reservation. A third UE may transmit a negative sidelink response indicating that the set or the segment of the data resources is unavailable for reservation, or may refrain from transmitting a negative sidelink response if the set or the segment of the data resources is available for reservation. If the requested data resources are available, then the first UE may transmit a sidelink confirmation reserving the requested data resources.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. In one aspect a wireless communication technique takes into account the load of a donor gNB before a relay decides to reselect from one donor gNB to another. In another aspect, a wireless communication technique ensures that relays are handed over to base stations that will be able to serve the relay as the mobile relay continues to follow its expected path (e.g. streets or tracks).

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a sidelink scheduling request for groupcast sidelink communications with a set of one or more UEs. The base station may determine one or more UEs of the set of UEs and time-frequency resources for groupcast sidelink communication between the first UE and the one or more UEs. The first UE may receive, from the base station, a groupcast sidelink grant that indicates time-frequency resources for groupcast sidelink communications between the first UE and one or more UEs. The first UE may transmit, via the time-frequency resources indicated by the groupcast sidelink grant, a groupcast sidelink message to the one or more UEs. The one or more UEs may also receive the sidelink grant, and may monitor the time-frequency resources for a groupcast sidelink communication from the first UE.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.
