Abstract: Certain aspects of the present disclosure provide techniques for unlicensed channel occupancy time sharing based on received signal strength. A method that may be performed by a first user equipment (UE) includes receiving a first transmission from a second UE, the first transmission indicating the second UE has acquired a frequency band for a channel occupancy time (COT). The method may also include transmitting a signal within the frequency band during the COT in response to a signal strength of the first transmission as received by the first UE being greater than at least one threshold.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communications in an unlicensed spectrum. A method that may be performed by a first device includes sensing that an unlicensed frequency band is idle, the unlicensed frequency band consisting of a plurality of subchannels. The method also includes, in response to sensing that the unlicensed frequency band is idle, transmitting, by the first device, at least one of a data signal or a reservation signal during an entire duration of a time period over one or more subchannels of the plurality of subchannels, the at least one of the data signal or the reservation signal reserving the unlicensed frequency band during the time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.

Abstract: Aspects relate to group-based reference signal broadcast in a wireless communication network. A first wireless communication device may transmit a first group formation broadcast message associated with a first positioning group comprising a first plurality of wireless communication devices including the first wireless communication device. The first wireless communication device may receive a second group formation broadcast message associated with a second positioning group comprising a second plurality of wireless communication devices including a second wireless communication device. The second positioning group may be associated with a channel occupancy time (CoT) in a sidelink channel. The CoT may comprise transmission opportunities configured to be used by the second plurality of wireless communication devices for communicating reference signals. The first wireless communication device may initiate transmission of reference signals by the first plurality of wireless communication devices using additional transmission opportunities within the CoT associated with the second positioning group.

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.
