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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a shared channel occupancy for a packet transmission resource; determine a range metric for die shared channel occupancy based at least in part on location information; determine whether to share the shared channel occupancy for packet transmission using the packet transmission resource based at least in part on the range metric; and selectively transmit one or more packets in the shared channel occupancy based at least in part on a result of determining whether to share the shared channel occupancy. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communications in an unlicensed spectrum. A method that may be performed by a device includes sensing a channel for interference in each of a plurality of time intervals in order of time until interference below a threshold is sensed for one of the plurality of time intervals or interference above the threshold is sensed for all of the plurality of time intervals, the plurality of time intervals being of a time window. The method may also include sensing interference to be above a threshold in a first portion of the one of the plurality of time intervals. The method may also include sensing interference to be below the threshold in a second portion of the one of the plurality of time intervals that occurs later in time than the first portion.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the disclosure provide techniques for wireless devices utilizing wireless communications systems to perform radar operations to leverage challenges within radar signaling to detect one or more adverse parties attempting to spoof one or more radar signals. For example, a base station may transmit, to one or more vehicles, a message including an indication of a challenge type, when the challenge is to be applied, or both. Based on the challenge, one or more vehicles may detect that a device associated with the adverse party is not following the challenge as dictated in the message. Based on the detection, the one or more vehicles may report, to the base station, the detection of an adverse party attempting to spoof radars within the wireless communications system.
