    Abstract: Methods, systems, and devices for wireless communications are described. A receiver user equipment (UE) may communicate with a transmitter UE in a sidelink channel to report a congestion index to the transmitter UE and/or additional transmitter UEs, where the transmitter UE(s) may then adjust one or more sidelink operation parameters based on the reported congestion index. In some cases, the transmitter UE may report the congestion index to an upper layer, to other transmitter UEs, to application layers, or a combination thereof. The transmitter UEs 115 and/or application layer may then adjust one or more sidelink transmission operation parameters based on the reported congestion index. For example, the transmitter UEs and/or application layer may adjust threshold values to lessen a number of retransmissions and lessen congestion.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first zone identifier (ID) corresponding to a first zone in which the transmitter UE is located, determines a distance threshold based on a distance requirement of an application associated with the transmitter UE, determines a second zone ID based on the first zone ID, the distance threshold, a size of the first zone, or any combination thereof, and transmits the second zone ID and the distance threshold to one or more receiver UEs. In an aspect, the receiver UE receives the second zone ID and the distance threshold, determines a distance between the receiver UE and the transmitter UE based on the second zone ID and a location of the receiver UE, and transmits, based on the distance being less than the distance threshold, a feedback message to the transmitter UE.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.

    Abstract: In one aspect, a method includes determining, by a user equipment (UE), a channel busy ratio (CBR) window for a CBR measurement for one or more resources; determining, by the UE, a CBR measurement value for the CBR window and for the one or more resources; determining, by the UE, a channel occupancy ratio (CR) window based on a first number of subframes used for a history of past transmissions and based on a second number of subframes used for future planned transmissions and corresponding retransmissions; and determining, by the UE, a CR value for the CR window based on subchannels used for the one or more resources for the first number of subframes and based on subchannels estimated for the one or more resources for the second number of subframes. In another aspect, a method includes determining a CR window based on a CBR measurement value.
