Abstract: A user equipment (UE) in a vehicle (V-UE) broadcasts multi-phased ranging signals with which other entities may determine the range to the V-UE. The multi-phased ranging signals may include a first message, which may be broadcast in the Intelligent Transport System (ITS) spectrum, includes ranging information, such as a source identifier, location information for the broadcasting V-UE, and an expected time of broadcast of the ranging signal. The ranging signal may then be broadcast at the expected time and may include the source identifier. A second message, which be broadcast in the ITS spectrum, may include clock error information for the V-UE. A receiving entity may determine the range to the V-UE based on the time of arrival of the ranging signal and the expected time of transmission, as well as the clock error information. The receiving entity may further generate a position estimate based on the received location information.

Abstract: A method of wireless communication performed by a sensing user equipment (UE) includes identifying available resources during a sensing window. The method also includes receiving a request to share the available resources with a transmitter UE. The method further includes determining the sensing UE satisfies a sharing condition. The method still further includes sharing the available resources with the transmitter UE based on satisfying the sharing condition.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: A receiving device identifies a collision between first resources reserved by a first transmitting device and second resources reserved by a second transmitting device and transmits a collision indication to the first transmitting device or the second transmitting device based on the identified collision. A transmitting device that receives a collision indication from the receiving device backs off from transmitting during the resources received by the resource reservation in response to receiving the collision indication from the receiving device.

Abstract: Aspects relate to a demodulation reference signal (DMRS) in a sidelink wireless communication network. In some examples, a sidelink device generates a DMRS based on first and second identifiers of the sidelink device. In some examples, a sidelink device generates a DMRS based on an initialization parameter and/or at least one scaling parameter. In some examples, the initialization parameter may be based on a first identifier of a sidelink device. In some examples, the at least one scaling parameter may be based on a second identifier of a sidelink device. In some examples, a first sidelink device synchronizes with a second sidelink device based on broadcast channel information that is obtained by using DMRS information to decode a received broadcast signal. In some examples, the DMRS information may be based on first and second identifiers of the first sidelink device.

Abstract: Aspects presented herein may enable a transmitting device to encode and transmit coordination information and data in separate transport blocks, such that the transmitting device may update the coordination information without altering the transport block carrying the data. In one aspect, an apparatus encodes coordination information for sidelink resources in a first transport block. The apparatus encodes data in a second transport block. The apparatus transmits a first transmission on a PSSCH, the first transmission including the first transport block comprising coordination information and the second transport block.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources.
