Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a first wireless device may transmit sidelink control information to a second wireless device, which includes a first scheduling for an uplink transmission by a second wireless device during a first slot. The second wireless device may decode the sidelink control information to determine an operating mode of the first wireless device during the first slot, such as a transmitting mode or a receiving mode. Based on the operating mode, the second wireless device may drop or delay the uplink transmission. In some cases, the first wireless device may schedule an uplink transmission to be performed by the second wireless device during a second slot, and the first wireless device may switch from a transmitting mode to a receiving mode in order to receive the scheduled uplink transmission from the second wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a base station, a downlink communication that includes an indication of a sidelink grant associated with the first UE. The first UE may identify, based at least in part on the sidelink grant, one or more sidelink resources in which a second UE is to transmit sidelink control information (SCI) to the first UE. The SCI may include information associated with a sidelink data transmission from the second UE to the first UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) and a second UE may communicate in accordance with a sidelink resource allocation Mode 1 according to which the UEs may receive scheduling information from a base station. The first UE may receive first-stage sidelink control information (SCI-1) from the second UE based on a destination filter indicator associated with one or more intended receivers of a message scheduled by the SCI-1. The first UE may decode the SCI-1 and determine, based on the destination filter indicator conveyed by the SCI-1, whether the first UE is an intended receiver of the message scheduled by the SCI-1. If the first UE is an intended receiver, the first UE may decode the message. If the first UE is not an intended receiver, the first UE may refrain from decoding the message.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a target UE receives zone information associated with a set of zones, the zone information indicating, for each of a plurality of candidate UEs for a sidelink-assisted position estimation procedure of the target UE, a zone identifier of a zone in which the respective candidate UE is located. The target UE selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the zone information. The target UE performs the sidelink-assisted position estimation procedure with at least the selected one or more candidate UEs.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

Abstract: Methods, systems, and devices for wireless communications are described for efficient allocation of feedback resources and transmission of feedback for low latency communications. A first user equipment (UE) may be allocated uplink resources for uplink transmissions having one or more gaps during which a second UE may transmit feedback information to initiate a retransmission within specified time limits to achieve desired quality of service (QoS) targets. The one or more gaps may be provided through a downlink control information message that indicates uplink resources to the first UE based on a first starting transmission symbol and a first length indicator, and a second starting transmission symbol and a second length indicator. The one or more gaps may be additionally or alternatively provided through one or more reserved symbols, and the first UE may skip uplink transmissions in one or more reserved symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive, from a second UE such as a PLC, sidelink control information scheduling a first transmission to be transmitted by the first UE to the second UE on a first set of resources in a dedicated resource pool for sidelink control signaling. The first UE may receive an indication that a second transmission is scheduled to be transmitted by the first UE on a second set of resources which at least partially overlaps in time with the first set of resources. The first UE may transmit at least one of the first transmission or the second transmission in accordance with a conflict resolution rule based on the second set of resources at least partially overlapping with the first set of resources.
