Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may identify a limited detection range, such as a Line of Sight (LoS) blockage or reduced coverage. The UE may request inter-vehicle assistance from a centralized control entity to overcome this limitation. The CE may transmit an indication of a set of target objects tracked by a sensor at the UE and a level of accuracy for tracking the set of target objects. In turn, the centralized control entity may request sensor information from one or more UEs with a complete LoS, a larger coverage area, or both. Based on the available sensor information, the centralized control entity may collect and transmit the sensor information back to the first UE in response to the request for assistance.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a radar device. The radar device determines a resource pool configuration indicating a radar band partitioned into a plurality of non-overlapping subbands. At least two of the plurality of non-overlapping subbands use resource elements (REs) that differ in at least one of a frequency size or a time duration. The radar device transmits a radar waveform using at least one RE within a subband of the plurality of non-overlapping subbands.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive coordination information for sidelink communication in a distributed scheduling mode. The UE may select, in the distributed scheduling mode, a value for a sidelink communication parameter based at least in part on the coordination information. The UE may transmit a sidelink communication using the value of the sidelink communication parameter that is selected based at least in part on the coordination information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. To support cross-carrier sidelink resource reservation, a user equipment (UE) may transmit sidelink control signaling in a carrier in a licensed frequency spectrum band (e.g., a licensed carrier) that reserves one or more sidelink resources of a carrier in an unlicensed frequency spectrum band (e.g., an unlicensed carrier) for transmission of sidelink data. For example, the UE may determine the one or more sidelink resources for transmission of the sidelink data in the unlicensed carrier and may transmit the sidelink control signaling in the licensed carrier to reserve the one or more sidelink resources. The UE may then transmit the sidelink data in the one or more sidelink resources of the unlicensed carrier. In some examples, the UE may perform a channel access procedure before transmitting the sidelink data and may transmit the sidelink data based on the channel access procedure.

Abstract: Methods, systems, and devices for wireless communications are described for shared radio frequency spectrum band access information. A sensing device may monitor one or more frequencies of the shared radio frequency spectrum band and may receive signaling indicating access information (e.g., automated frequency control information). The access information may indicate one or more frequencies of the shared radio frequency spectrum band that are accessible for the sensing device. The scheduling device may obtain the access information from an access point, local storage media, or the like. In some examples, the scheduling device may transmit signaling indicating the accessible frequencies based on a request message from the sensing device. The sensing device may receive the access information and may communicate on one or more of the indicated frequencies accordingly.

Abstract: Aspects for reducing interference for transmissions in unlicensed frequency bands are disclosed. An apparatus, e.g., a user equipment (UE) with information to transmit, identifies before transmitting the information in an unlicensed frequency spectrum, a specified duration of a listen-before-talk (LBT) operation in that spectrum. Based on the specified duration, the UE reduces a transmission time duration of a slot of the UE to increase a time duration of a remainder of the slot sufficient to prevent, or decrease the likelihood of, a transmission by the UE in the slot from interfering with an LBT operation by another UE.

Abstract: Techniques for wireless communications are described. A communication device, such as a user equipment (UE) may determine a resource usage level in a wireless communications system. Additionally or alternatively, the UE may determine a transmission property associated with sidelink communication at the UE. The UE may adjust, based on the determined resource usage level in the wireless communications system or the determined transmission property associated with the sidelink communication at the UE, or a combination thereof, a sensing mode of a sensing procedure or a sensing parameter of the sensing procedure, or a combination thereof. In some examples, the UE may identify a set of resources used for the sidelink communication at the UE based on the adjusted sensing mode or the adjusted sensing parameter, or a combination thereof. The UE may perform the sidelink communication based on the sensing mode or the sensing parameter, or a combination thereof.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes transmitting data to at least one receiver UE in an unlicensed spectrum used for sidelink communication, determining if a resource in a slot is available for the at least one receiver UE to provide acknowledgment feedback for the data transmission, and transmitting a reservation signal in the slot if the resource is determined to be available.
