Abstract: Certain aspects of the present disclosure provide techniques for resource allocation with collision indication for sidelink communication. A method that may be performed by a first user equipment (UE) includes receiving a first sidelink transmission from a second UE indicating a first resource reservation; receiving a second sidelink transmission from a third UE indicating a second resource reservation; and transmitting, to at least the second UE, feedback comprising: hybrid automatic retransmission request (HARQ) feedback regarding the first sidelink transmission; and an indication of whether a collision is detected by the first UE between the first resource reservation and the second resource reservation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine resource selection priority levels associated with available resources for sidelink signaling in an unlicensed radio frequency spectrum band, the resources selection priority levels may be determined based on resource reservation information of the available resources, a time domain location of the available resources, or both. For example, a first resource of the available resources may be associated with a higher priority than a second resource of the available resources in resource selection. The UE may select one or more resources for the sidelink signaling from the available resources based on the resource selection priority levels associated with the available resources. The UE may transmit the sidelink signaling on the unlicensed radio frequency spectrum band using the one or more selected resources.

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 carrier selection for sidelink communications in an unlicensed spectrum. A method that may be performed by a first sidelink user equipment (UE) includes determining one or more carriers, from a set of configured carriers, in an unlicensed spectrum to use for communicating with a second sidelink UE and communicating with the second sidelink UE using the determined one or more carriers.

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: 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.
