Abstract: Aspects of the disclosure relate to wireless communications including sidelink communications between wireless devices. Adaptation of a resource exclusion reference signal receive power (RSRP) threshold for scheduling resources for a device using such sidelink communications includes utilization of first and second time/frequency windows of available resources to determine the number of free resources in each window. If the free resources in either window are less than a predetermined free resource threshold, the resource exclusion RSRP threshold is increased to gain further potential time/frequency resources that may be scheduled by the device.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink communications between user equipment's (UEs). Per one technique, during a discovery opportunity, a first UE and a second UE may identify a subset of beam pairs suitable for communication, and schedule a discontinuous transmission (DTX) occasion during the discovery opportunity. During the DTX occasion, the first UE and second UE may perform a beam refinement procedure to determine a beam pair (BP) over which to communicate, from the identified subset of beam pairs. The beam refinement procedure may include beam narrowing of at least one of the identified subset of beam pairs.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a first UE. The method includes receiving a data transmission from a second UE. The data transmission is associated with a feedback procedure for data transmissions that is based on a distance between the first UE and a transmitting UE. When the first UE (i) cannot successfully decode the data transmission and (ii) cannot determine the distance between the first UE and the second UE, the method includes determining whether one or more criteria are satisfied for sending, to the second UE, a negative acknowledgement (NACK) for the data transmission as part of the feedback procedure, where the NACK indicates the first UE could not successfully decode the data transmission. The method including transmitting the NACK to the second UE when the one or more criteria are satisfied.

Abstract: An apparatus receives, in a transmission from a second UE, an indication of reserved resources for the second UE. The apparatus measures a received power of the transmission from the second UE. The apparatus excludes the reserved resources indicated by the second UE from a set of candidate resources based on the received power of the transmission from the second UE meeting a threshold, where the threshold is based at least in part on whether the reserved resources are associated with a retransmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive, on a sidelink and from a second wireless communication device, resource reservation information associated with the second wireless communication device. The resource reservation information may identify sidelink resources that are reserved for the second wireless communication device for transmission on the sidelink. The first wireless communication device may transmit, on the sidelink, the resource reservation information to a third wireless communication device. Numerous other aspects are provided.

Abstract: A method of wireless communication performed by a sensing user equipment (UE) includes identifying available resources during a sensing window. The method also includes receiving a request to share the available resources with a transmitter UE. The method further includes determining the sensing UE satisfies a sharing condition. The method still further includes sharing the available resources with the transmitter UE based on satisfying the sharing condition.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a first sidelink grant for a transmission between the first UE and the second UE. The first UE may communicate the transmission according to the sidelink grant. The first UE may monitor a configured duration of a sidelink round trip time timer from the transmission. The first UE may monitor a configured duration of a sidelink retransmission timer from an end of the sidelink round trip time timer. The first UE may allow start of a discontinuous reception (DRX) mode after the duration of the sidelink retransmission time if a second grant is not received during the sidelink retransmission timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a wireless in-vehicle network (wIVN) capability indication that indicates that the UE is associated with a vehicle that includes a wIVN; receive a response to the wIVN capability indication from another UE; and provide configuration information to a wIVN control unit of the vehicle associated with configuring the wIVN based at least in part on the response. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources.

Abstract: Certain aspects of the present disclosure provide techniques for low power channel sensing for pedestrian user equipments (P-UEs). A method that may be performed by a UE (e.g., such as a P-UE) includes determining a level of channel congestion for a channel during a first sensing duration. The method includes determining a second sensing duration and a transmission duration based on the level of channel congestion for the channel determined from the first sensing duration. The method includes sensing the channel for the second sensing duration. The method includes transmitting on the channel for the transmission duration.
