Abstract: A user equipment (UE), for example, used with a Vulnerable Road User, determines a relative position of the UE and sends a report of the relative position to one or more vehicle On-Board Units (OBUs), wherein the report further includes an identification of the one or more reference points. The relative position may be with respect to one or more reference points, which may be stationary or moving. The relative position may be determined and reported based on identifiers for the one or more reference points and distance or distance vectors to each of the one or more reference points. The relative position may be determined based on data from one or more one board sensors, such as radar, lidar, ultrasound, or camera, as well as with wireless transceivers. The relative position may additionally include a heading and a placement with respect to one or more street elements.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a first transmission from a first device to be received at a second device. The second device may determine one or more interference parameters (e.g., a maximum allowable interference power) for receiving the first transmission from the first device, and the second device may transmit an indication of the one or more interference parameters using a full-duplex operation (e.g., using resources overlapping with resources used to receive the first transmission). The third device may receive the indication of the one or more interference parameters and determine transmission parameters (e.g., a maximum transmit power) for communicating with a fourth device based on the one or more interference parameters. The third device may transmit a second transmission to the fourth device based on the transmission parameters.

Abstract: Certain aspects of the present disclosure provide techniques for air interface and sidelink discontinuous reception alignment for inactive/idle user equipment. A method performed by a user equipment (UE) includes receiving, from a second user equipment at a first user equipment over a sidelink interface, discontinuous reception (DRX) configuration assistance information and transmitting, from the first user equipment to a network via an air interface, the DRX configuration assistance information. The method may further include receiving, from the network at the first user equipment via the air interface: modified air interface DRX configuration information for the first user equipment, and sidelink DRX configuration information for the first user equipment and the second user equipment, wherein the sidelink DRX configuration information is based on the DRX configuration assistance information; and transmitting, from the first user equipment to the second user equipment over the sidelink interface, the sidelink DRX configuration information.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication by a network entity. The method generally includes generating a configuration message for a user-equipment (UE) to perform one or more reference signal (RS) measurements on one or more resources of a sidelink channel, transmitting the measurement configuration message, receiving a measurement report indicating results of the one or more RS measurements, and transmitting a scheduling message indicating resources for sidelink transmission on the sidelink channel.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a first user equipment (UE) receiving an indication of a set of sidelink resources and an indication of a set of uplink resources for transmitting sidelink feedback information. The first UE may receive a sidelink shared channel transmission from a second UE and upon receiving the sidelink shared transmission, generate feedback information regarding the sidelink shared channel transmission and transmit the feedback information directly to the base station using the set of uplink resources.

Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support short reference signals for sidelink communication. A transmitting user equipment (UE) and a receiving UE may receive, from a base station, configuration signaling that indicates a set of sidelink resources that includes a set of slots within a subcarrier. A subset of the slots may include a first set of symbols allocated to a physical sidelink shared channel (PSSCH) and a second set of symbols allocated to a reference signal, where the first set of symbols comes before the second set of symbols in a time domain. The transmitting UE may transmit, to the receiving UE, a reference signal over the second set of symbols and the receiving UE may utilize the reference signal to decode data message received from the transmitting UE.
