Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.

Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

Abstract: Wireless communication devices are adapted to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a reservation signal to reserve one or more sidelink resources for use by another device, and receive a sidelink transmission from the other device on at least a portion of the one or more reserved sidelink resources. According to another example, a wireless communication device can detect a reservation signal from another device, where the reservation signal is configured to reserve one or more sidelink resources, and transmit a sidelink transmission on at least a portion of the one or more of the sidelink resources reserved by the other device. Other aspects, embodiments, and features are also included.

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: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

Abstract: Certain aspects of the present disclosure provide techniques for improving sidelink positioning via messaging between wireless nodes, e.g., roadside service units (RSUs). A method that may be performed by a user equipment (UE) includes receiving a first positioning reference signal (PRS) from a first wireless node, receiving a second PRS from a second wireless node, receiving, from the first wireless node, an estimate of a first clock error component between the first wireless node and the second wireless node, and estimating a position of the UE, based on the first PRS, the second PRS, and the estimate of the first clock error component.
