Abstract: Certain aspects of the present disclosure provide techniques for slot format for sidelink communication. A method that may be performed by a user equipment (UE) includes transmitting a data signal; refraining from transmitting during a gap portion occurring in time after the transmission of the data signal, wherein the gap portion has a duration less than or equal to a threshold; receiving a feedback signal after the gap portion, wherein the feedback signal comprises at least a signal and hybrid automatic retransmission request (HARQ) feedback for the data signal; receiving another signal; and adjusting a gain applied to the other signal based on the signal.

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 first device may select a first time-frequency-angular resource that is identified in a time domain, in a frequency domain, and in an azimuth angle domain. The first device may transmit a first communication using the first time-frequency-angular resource. 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 receive, from a network entity, a sidelink resource sub-pool configuration that indicates a partition of a sidelink resource pool into a first sidelink resource sub-pool associated with radar transmissions and a second sidelink resource sub-pool associated with sidelink transmissions. The UE may transmit a radar transmission using resources of the first sidelink resource sub-pool based at least in part on the sidelink resource sub-pool configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a radar which is used for object detection, such as a vehicle UE detecting other vehicle UEs in a vehicle-to-everything (V2X) communications system. The UE may be configured for coordinated interference, where radars transmit a common waveform while applying different delays to prevent negative co-channel interference effects, such as false or ghost targets. The techniques described herein support configuring a common configuration for network-assisted coordinated interference by considering capabilities of UEs and radars within a geographic area controlled by a network entity. The network entity may identify and indicate a waveform configuration which is used by radars within the geographic control area of the network entity.

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.
