Abstract: Certain aspects of the present disclosure provide a method performed by a first apparatus including a radar device. The first apparatus transmits first operating information associated with the first apparatus indicating a geographical location and a direction of the first apparatus to a second apparatus in an environment. The first apparatus receives second operating information from the second apparatus indicating a geographical location and a direction of the second apparatus. The first apparatus identifies a group of interfering apparatuses, including the first apparatus and the second apparatus, based on the first and second operating information. The group of interfering apparatuses is associated with a same time synchronization source. The first apparatus transmits a first plurality of signals via the radar device based on a common radar transmission configuration for the group of interfering apparatuses.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may reserve one or more time frequency resources in an unlicensed frequency spectrum band for one or more sidelink transmissions. The UE may reserve the time frequency resources through a sidelink message transmitted in a first slot of a shared channel occupancy (CO). The UE may monitor a subset of slots before the reserved time frequency resources for sidelink transmissions from other UEs sharing the CO. The monitoring of the subset of slots may include decoding control messages or control information in each of the subset of slots, a reference signal received power (RSRP) measurement of sidelink transmissions in the subset of slots, channel sensing with energy detection in a sensing window, or a combination thereof. The UE may communicate in the reserved slot based on the monitoring.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, an application enabler layer (e.g., a vehicle-to-everything (V2X) application enabler (VAE) layer), may identify a congestion control configuration that includes capabilities for collecting operation information. The application enabler layer may receive, from a set of user equipment (UEs), the operation information in accordance with the capabilities. Then, the application enabler layer may generate congestion control instructions for one or more UEs of the set of UEs based on the received operation information. Additionally or alternatively, an application enabler architecture layer (e.g., a service enabler architecture layer for verticals (SEAL)) may identify a congestion control configuration including capabilities for collecting operation information and monitor sidelink performance for the set of UEs in accordance with the capabilities. The application enabler architecture layer may identify a congestion status for a communication type based on monitoring the sidelink performance.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an aspect, an application layer in a user equipment (UE) receives, from an access layer in the UE, a quality of service (QoS) indication comprising a metric that represents a quality of one or more radio bearers used for a vehicular communication with one or more other UEs. The application layer performs a transmission control over the vehicular communication based on the QoS indication.

Abstract: During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.

Abstract: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.
