Abstract: To facilitate coexistence of a first radio access technology (RAT) and a second RAT, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating based on a RAT includes receiving a sidelink resource reservation from a second wireless device based on a second RAT, the sidelink resource reservation indicating a first set of resources. The example method further includes determining whether to exclude, from a candidate resource set for the first RAT within a sidelink resource pool for the first RAT, resources that overlap with the set of reserved resources for the second RAT. The example method further includes transmitting a sidelink transmission using one or more sidelink transmission resources selected from the candidate resource set in the sidelink resource pool for the first RAT.

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.

Abstract: This disclosure provides systems, methods and apparatuses for wireless communication that may allow a user equipment (UE) to determine its relative position and distances to other UEs more accurately than standard vehicle-to-everything (V2X) communications allow. In some implementations, a UE (or other wireless communication device) participating in a positioning operation may transmit and receive positioning signals on an unlicensed radio band, and may transmit and receive non-positioning signals on a V2X channel (or on another suitable channel) of a radio access network (RAN). The positioning signals may include positioning reference signals (PRSs) associated with observed time difference of arrival (OTDOA) positioning operations, ranging signals associated with round-trip time (RTT) positioning operations, or other suitable signals from which the position of the UE can be determined.

Abstract: The present disclosure provides for centralized, scheduler-based handling for UEs which transmit data to and receive data from a maneuver coordinator based on V2X communication. Once a UE is aware of the maneuver coordinator, the UE may send a request to the maneuver coordinator for maneuver operation scheduling. The maneuver coordinator then schedules and coordinates the UE's operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a wake up time period corresponding to a wake up cycle, transmit a message that includes an identifier of the UE within a first resource pool during a first portion of the wake up time period based on the wake up cycle, and monitor for a paging signal from a vehicle UE during a paging occasion of the wake up time period based on transmitting the message. A vehicle UE may identify a wake up configuration for a wake up time period, receive, within a first portion of the wake up time period, a message within a resource pool that includes the identifier of the UE. The vehicle UE may transmit a paging signal within a paging occasion of the wake up time period.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) carried by a pedestrian (e.g., a P-UE) may receive control signaling that indicates a resource allocation for a sidelink channel for pedestrian to vehicle communications. The P-UE may transmit, within the resource allocation of the sidelink channel, a message that includes an identifier of the P-UE based on movement data of the P-UE being classified as pedestrian movement. The P-UE may monitor the sidelink channel for a collision warning message from a vehicle UE that includes the identifier of the P-UE based on transmitting the message. If the P-UE receives a collision warning message that includes its identifier, the P-UE may present an alert based on receiving the collision warning message.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for transmitting ranging signals in a vehicle-based communication system. The configuration may identify a plurality of channels to be used for the ranging signals and timing for the ranging signals. The wireless device may transmit the configuration to a receiver and transmit ranging signals based at least in part on the configuration. The receiver may use the ranging signals to determine a distance between the receiver and the wireless device. The receiver may use the determined distance to update positioning information or operate a motor vehicle.

Abstract: Methods, systems, and devices for wireless communications are described that improve privacy in wireless communications, such as communications by a user equipment (UE), which may in some cases be a vehicle UE. For example, various vehicle-to-everything (V2X) transmissions may be unencrypted, and a vehicle may be expected to periodically change one or more identifiers it uses for various communication services. Privacy may be enhanced, for example, via encryption key roll-over, as well as roll-over of one or more other identifiers associated with a UE that may potentially be used by an observer to track the UE. The UE may transmit a message that includes an updated lower layer identifier (e.g., a layer-2 (L2) identifier) to another UE in a V2X unicast communications link, which may trigger a change in identifiers of a set of identifiers and an updated security context. All or a portion of the message may be encrypted.
