Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may transmit, over an unlicensed carrier, an initial transmission of a transport block (TB) satisfying a condition and an indication that a retransmission of the TB will be communicated over a licensed carrier. The apparatus may retransmit the TB over the licensed carrier based at least in part on a failure of the transmission of the TB over the unlicensed carrier. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink message (e.g., a scheduling request) indicating one or more beam directions (e.g., one beam direction, a set of beam directions, a sequence of beam directions), one or more beamwidths (e.g., for the one or more indicated beam directions), an angular area of interest for radar sensing, or a combination thereof. The network entity may then provide, to the UE, a grant of resources for performing the radar sensing on specific radar sensing transmit beams (e.g., that will not interfere with other radar sensing by other UEs, uplink communications form other UEs, sidelink communications by other UEs, etc.). The UE may indicate the directions of the beams with reference to a global coordinate system. The network may configure the UE with lookup tables (LUTs) defining relationships between indices, beam directions and/or beamwidths.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit an orthogonal frequency division multiplexing (OFDM) signal on K subsets of N subcarriers, where the signal includes a sequence of modulated symbols for each subset of the K subsets that is distinct for each subset. The wireless device may receive a reflected OFDM signal that corresponds to the OFDM signal. The wireless device may process the reflected OFD.M signal with K mixers, where mixer frequencies for the K mixers are separated by N subcarriers spacing, to form K portions of a range spectrum from the reflected OFDM signal. The wireless device may combine the K portions to form the range spectrum. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a discovery message to discover another UE with which to establish a cooperative radar sensing session. The first UE may receive, from a second UE, a join request for the first UE to establish the cooperative radar sensing session with the second CE, The first UE may transmit, to the second UE, an acceptance indication based at least in part on the join request. The first UE may communicate with the second UE to establish a joint configuration to be used by the first UE and the second UE for the cooperative radar sensing session, Numerous other aspects are described.

Abstract: Methods systems, and devices for wireless communications are described. A first wireless device may transmit a first radar signal in a first frame, and may receive a reflected signal corresponding to the first radar signal in a second frame. The first wireless device may also receive a number of different transmissions including at least a second transmission from a second wireless device. To determine which signals are reflections from the first radar signal and which signals are interference. the first wireless device may monitor a third frame that is subsequent to the first and second frames for one or more interfering signals during a silence interval. In some other cases, the first wireless device may transmit a request for the second wireless device to modify a timing offset for the second transmission, and may monitor for the second transmission which may be shifted in frequency according to the timing offset.

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. Each user equipment (UE) in a vehicle-to-everything (V2X) system may select a hopping pattern for transmitting a set of radar signals. A victim UE may experience interference from an interfering UE. The victim UE may receive a set of radar signals in a set of transmission frames from the interfering UE. The victim UE may detect a hopping pattern from the set of radar signals based on receiving the set of radar signals in the set of transmission frames. The victim UE may transmit a sidelink message to an interfering UE for interference coordination based on detecting the hopping pattern.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device may generate a radar signal including a set of waveforms (e.g., chirps) based at least in part on a waveform configuration of the communication device. Each respective waveform of the set of waveforms may be associated with at least one parameter of a set of parameters. A value of the at least one parameter may be different for each respective waveform of the set of waveforms (e.g., each chirp of a set of chirps). The communication device may transmit the generated radar signal during at least one frame of a set of frames.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink carrier aggregation with cross-carrier feedback are disclosed herein. An example method for wireless communication at a first wireless device includes receiving, from a second wireless device, a first sidelink message including a first transport block (TB) on a first carrier. The example method also includes generating a first Hybrid Automatic Repeat Request (HARQ) feedback for the first TB. The example method also includes determining a first feedback carrier to transmit cross-carrier feedback. The example method also includes mapping the first HARQ feedback for the first TB to the first feedback carrier, the first feedback carrier being different than the first carrier. The example method also includes transmitting the first HARQ feedback on the first feedback carrier to the second wireless device.
