Abstract: Certain aspects of the present disclosure provide techniques for coordinating waveform parameters and frame delays for multi-radar coexistence. An example method performed by an apparatus comprising a radar device includes transmitting, based on a transmission configuration, one or more first signals of a plurality of signals in an environment via the radar device in a first frame of a plurality of frames according to a first delay value occurring after a frame prior to the first frame and transmitting one or more second signals via the radar device in at least a second frame of the plurality of frames according to a second delay value occurring after the first frame based on the transmission configuration. In some cases, the transmission configuration comprises a common transmission configuration for use in the environment. Additionally, in some cases, the second delay value is different from the first delay value.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless device may receive one or more parameters from a roadside unit (RSU) via sidelink communication between the wireless device and the RSU, the one or more parameters indicating one or more characteristics regarding a sidelink positioning operation with the RSU or regarding a surrounding environment of the RSU. The wireless device may determine a whether or how to use a result of the sidelink positioning operation with the RSU with a result of a positioning estimation procedure of the wireless device based on the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a transmit diversity configuration for transmitting multiple sidelink messages. The UE may identify a transmit diversity configuration that indicates a set of component carriers (CCs) available for sidelink communication. The UE may transmit, based on the transmit diversity configuration, a first sidelink message having a first redundancy version (RV) of a transport block (TB), and a second sidelink message having a second RV of the TB, on multiple CCs. In a second case, the UE may identify a transmit diversity configuration indicating a set of precoding matrices. The UE may transmit the first sidelink message, including a TB or an RV of a TB, precoded using a first precoding matrix and a second sidelink message, including a TB or an RV of a TB, precoded using a second precoding matrix on multiple CCs.

Abstract: Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications in unlicensed bands are provided. A method for wireless communication by a first user equipment (UE) may include measuring a first reference signal received power (RSRP) of a physical sidelink feedback channel (PSFCH) transmission transmitted during a channel occupancy time (COT) initiated by a second UE and accessing a first slot of the COT based on the first RSRP.

Abstract: In an aspect, the present disclosure includes a method and apparatus for sidelink communications for identifying at least one slot in a measurement window as a channel busy ratio (CBR) relevant slot, calculating a CBR based on at least a measurement in at least the CBR relevant slot, and transmitting, or refraining from transmitting, a sidelink transmission based at least on the CBR.

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 and a hop counter value associated with the shared channel occupancy. The user equipment may determine whether to transmit one or more packets in the shared channel occupancy based at least in part on the hop counter value associated with the shared channel occupancy. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced feedback transmission for sidelink communication in unlicensed spectrum. A method that may be performed by a first user equipment (UE) includes receiving a sidelink transmission in a frequency band from a second UE; and transmitting feedback comprising: hybrid automatic retransmission request (HARQ) feedback regarding the sidelink transmission, and an indication of a measure of an energy level of the frequency band as measured by the first UE

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit the sidelink message to a second UE via a sidelink communications channel of an unlicensed radio frequency spectrum band. The first UE or the second UE may transmit a reservation signal to retain the sidelink communication channel for corresponding feedback for the sidelink message (e.g., while the second UE generates a feedback transmission). The second UE may transmit the feedback transmission over the sidelink communication channel.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for channel selection in systems that utilize both licensed and unlicensed frequency bands. As will be described in greater detail below, user equipments (UEs) that share unlicensed frequency band may select a channel in an unlicensed frequency band and advertise their channel selection over a licensed frequency band, in an effort to coordinate communications other UEs. An example method may include selecting at least a first channel within an unlicensed band for communications with at least a second UE, and transmitting, on a licensed band, an indication of the first channel and location information for the selection.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first UE determines a set of resources for transmission of one or more sidelink PRSs. The first UE transmits a sidelink control message to reserve the set of resources for the transmission of the one or more sidelink PRSs. In another aspect, the second UE may receive the sidelink control message, and may (e.g., transmit and/or receive/measure) the one or more PRSs in accordance with the sidelink control message. In another aspect, a third UE may receive the sidelink control message, and may determine whether a transmission by the third UE on some or all of the set of resources is permitted based on the sidelink control message.
