Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a first indication, based at least in part on a first threshold, that a hybrid automatic repeat request (HARQ) discontinuous transmission (DTX) is caused by a listen-before-talk (LBT) failure. The UE may obtain a second indication, based at least in part on a second threshold, that the HARQ DTX caused by the LBT failure is a type of HARQ DTX that is to be counted for identifying a sidelink radio link failure (RLF). The UE may identify the sidelink RLF based at least in part on detecting a number of consecutive occurrences of the type of HARQ DTX occurrences. Numerous other aspects are described.

Abstract: An ego vehicle determines an intended maneuver and identifies a first set of agents for coordinating the intended maneuver. The ego vehicle also determines a spatial distance for obtaining a level of communication reliability with the set of agents that is greater than a communication reliability threshold. The ego vehicle further applies the determined spatial distance to a sensor-sharing message. The ego vehicle also transmits the sensor-sharing message to a second set of agents within the determined range. The ego vehicle performs the intended maneuver.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, an initial transmission of a transport block via a sidelink unlicensed band. The UE may receive, from the second UE, a negative acknowledgement (NACK) based at least in part on the initial transmission of the transport block. The UE may transmit, to the second UE and based at least in part on the NACK and a retransmission reservation, a retransmission of the transport block via the sidelink unlicensed band in a retransmission occasion of a plurality of retransmission occasions associated with the retransmission reservation.

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 receive one of a transmission profile, of an application executing on the UE, that indicates whether sidelink discontinuous reception (DRX) is required, or a sidelink communication that indicates whether sidelink DRX is supported. The UE may communicate with one or more other UEs in accordance with a configuration for sidelink DRX, or with sidelink DRX disabled, based at least in part on the transmission profile or the sidelink communication. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for cross-carrier sidelink channel state information (CSI) reporting. One aspect provides a method for wireless communication by a first user equipment (UE). The method generally includes transmitting, to a second UE, one or more channel state information (CSI) requests on one or more first component carriers (CCs), via one or more sidelink control informations (SCIs) that includes a CSI request flag and receiving, in response to the one or more CSI requests, one or more CSI reports from the second UE on one or more second CCs.

Abstract: Certain aspects of the present disclosure provide techniques for sensing window configuration for sidelink based ranging and positioning. For example, during sidelink-based ranging or sensing, a user equipment (UE) may determine the relative distance or position with other UEs. This may be realized by a UE broadcasting a wideband position reference signal (PRS) on an unlicensed band and measuring the round-trip time associated with a peer UE's PRS. The measurement accounts for a PRS transmission time transmitted by each UE. The UE may apply a sensing window to determine whether a neighboring UE has reserved PRS transmission times. The present disclosure provides methods and techniques for a network entity to configure a sensing window in a UE so that the UE may determine, during the sensing window, whether neighboring UEs have reserved a PRS transmission time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may configure a discontinuous reception (DRX) cycle of the first UE for a sidelink connection with a second UE. The UE may identify a mode that specifies whether the first UE is to receive a communication outside of an on duration of the DRX cycle if the on duration is extended due to receiving sidelink control information (SCI) reserving a resource outside of the on duration. The UE may communicate in accordance with the mode. Numerous other aspects are described.

Abstract: Certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes determining a configuration associated with sidelink for at least one communication; monitoring for at least one SCI after entering a sidelink discontinuous reception (DRX) on phase based on the configuration; receiving, from one or more other UEs, the at least one SCI during the sidelink DRX on phase for at least one communication; and determining an extension to the sidelink DRX on phase based on the at least one SCI scheduling at least one first resource for one or more transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.
