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: 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.
