    Abstract: A first apparatus may be a first network node or a component thereof, and may receive DCI from a second apparatus or a third apparatus. The second apparatus may be a second network node or a component thereof. The third apparatus may be a third network node or a component thereof. The DCI may include a scheduling grant for a first CC to be communicated over a channel and a HARQ feedback offset index value. The first apparatus may determine, based on the HARQ feedback offset index value, an offset value of a first plurality of offset values associated with a first CC. The first apparatus may transmit a HARQ feedback message in a slot of a second CC. The slot may be based on the determined offset value. The HARQ feedback message may indicate one of an ACK or NACK for data received from the second apparatus.

    Abstract: Apparatus, methods, and computer-readable media for facilitating a SL communication for mode 2 resource allocation are disclosed herein. An example method includes performing sensing on one or more SL resources to identify a first set of available resources. The example method further includes adjusting a first measurement threshold to a second measurement threshold based on a size of the first set of available resources being below an availability threshold. The example method further includes transmitting a sidelink message indicating a second set of available resources based on the second measurement threshold.

    Abstract: Wireless communications systems and methods related to reallocating resources assigned to sidelinks are provided. A first user equipment receives a preemption indication from a base station. The preemption indication is for reallocating resources allocated for communication between the first user equipment and the base station and for sidelink communication between the first user equipment and a second user equipment. Based on the preemption indication, the first user equipment reallocates the resources for the communication between the first user equipment and the base station. Based on the preemption indication, the first user equipment reallocates the resources for the sidelink communication between the first user equipment and the second user equipment.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control transmission and multiple downlink data transmissions to a user equipment (UE). The UE may schedule an uplink data transmission based on the downlink control transmission and may schedule transmission acknowledgement messages based on the multiple downlink data transmissions. The UE may identify that the scheduled uplink data transmission overlaps with the scheduled transmission acknowledgement messages. The UE may generate one or more acknowledgement codebooks for transmission of the multiple transmission acknowledgment messages and may multiplex the one or more acknowledgement codebooks with the uplink data transmission on the uplink data channel. In some cases, the UE may multiplex the codebooks based on determining that a set of timing thresholds are satisfied by an earliest of the multiple transmission acknowledgement messages and the uplink data transmission with respect to one or more downlink transmissions.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may operate in accordance with a multi-user (MU) multiple input-multiple output (MIMO) communication mode and may communicate with multiple other UEs over a same physical sidelink shared channel (PSSCH) resource. In some implementations, the first UE may transmit an indication of an MU-unicast mode for multiple sidelink transmissions to the multiple other UEs and may transmit the multiple sidelink transmissions to the multiple other UEs over the same PSSCH resource. In such implementations, the multiple other UEs may select physical sidelink feedback channel (PSFCH) resources to transmit feedback associated with the multiple sidelink transmissions in accordance with a PSFCH resource selection procedure associated with the MU-unicast mode. In accordance with the PSFCH resource selection procedure, the multiple other UEs may each select different PSFCH resources for their respective feedback transmissions.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing timing for inter-user equipment (UE) coordination to prevent or minimize interference or collisions between sidelink transmissions. A first UE may determine a time window in which to select sidelink resources for an inter-UE coordination message based on a minimum time configured for selecting the sidelink resources. The minimum time configured for selecting the sidelink resources for the inter-UE coordination message may be different from a minimum time configured for selecting sidelink resources for other sidelink messages. The first UE may then select the sidelink resources in the time window for the inter-UE coordination message and transmit the inter-UE coordination message on the selected sidelink resources to the second UE over a sidelink.
