    Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from another UE, a coordination message that includes resource information (e.g., a preference status) for communication resources. The UE receiving the coordination message may determine a status of one or more resources based on the resource information, an intended recipient of the coordination message (e.g., based on a destination identifier of the coordination message), or a communication connection associated with the one or more resources. The status may indicate that a respective resource of the one or more resources is available, reserved, preferred, or non-preferred, or some combination thereof. In some examples, the one or more resources may be for a sidelink connection or a unicast connection. The receiving UE may utilize the determined status to select one or more resources for a sidelink transmission.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to perform groupcast transmission on a sidelink channel of a high frequency band, such as a millimeter wave (mmW) band. The UE may transmit, via a sidelink channel, beamformed repetitions of a packet in multiple directions corresponding to multiple quality of service (QoS) profiles configured for transmission of the packet. The UE may determine precoders to transmit the packet in the multiple directions. Each repetition of the packet may be associated with a separate hybrid automatic repeat request (HARQ) process. The UE may perform precoder cycling to transmit the packet in the multiple directions, and the UE may retransmit the packet in directions where the initial transmission was unsuccessful.

    Abstract: An apparatus (e.g., a third UE) may be configured to detect at least one SPS conflict in a set of REs between a first SL (e.g., an SPS-based) transmission associated with a first UE and a second SL transmission associated with a second UE. The third UE may further be configured to transmit, upon detecting the SPS conflict, an indication of the SPS conflict to at least one of the first and second UEs. A first UE may be configured to receive, from the third UE, the indication of the SPS conflict, the indication of the SPS conflict including information regarding a set of resources associated with the detected conflict. The first UE may be further configured to initiate a resource re-selection for the first SL transmission based on the received indication and to transmit the first SL transmission based on the resource re-selection.

    Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to one or more UEs, an SL transmission in a first direction using a first precoder. The example method may further include retransmitting, to the one or more UEs based on a configured maximum number of directional retransmissions and without allocating additional processes and memory for the packet, the SL transmission in one or more directions different from the first direction using one or more precoders different from the first precoder based on a SL retransmission configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a control message indicating reservation of a first resource of a sidelink channel for a sidelink transmission. The first UE may receive a pre-conflict indication for the first resource based on the control message. In some cases, the first UE may disregard the pre-conflict indication, or may not disregard the conflict indication based on one or more factors. The first UE may perform resource re-selection to select a second resource for the sidelink transmission if the first UE receives the conflict indication at least a threshold amount of time prior to the first resource, and may transmit using the second resource. Otherwise, the first UE may report a negative acknowledgement (NACK) message from a physical (PHY) layer to a medium access control (MAC) layer.
