Abstract: Techniques for handling sidelink feedback signaling in situations where collisions would otherwise be experienced in a network communication link are shown and described. For example, sidelink feedback signaling handling techniques may provide for collision handling when sidelink HARQ is to be simultaneously transmitted with network communication radio interface uplink channel information (e.g., Uu HARQ, SR, CSI, etc.) on one or more Uu channel (e.g., PUSCH, PUSCH, etc.). In operation of sidelink feedback handling, a transmitter or intermediary UE of a sidelink communication link may decide whether and how to forward the sidelink HARQ to a corresponding base station. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present invention generally disclose wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a first resource pool associated with a first component carrier and a second resource pool associated with a second component carrier. The UE may transmit an indication of a resource reservation associated with a sidelink communication, wherein the resource reservation indicates a first set of resources associated with the first resource pool and a second set of resources associated with the second resource pool, and wherein the indication of the resource reservation is transmitted in at least one of a first control channel associated with the first component carrier or a second control channel associated with the second component carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) and a base station may establish communications using a first radio access technology (RAT). The first UE may receive control signaling indicating a configuration for a coexistence of resources between the first RAT and a second RAT, the coexistence of resources indicating an initial quantity of UEs in a system that use the first RAT or the second RAT. During a measurement period, the first UE may measure a control channel (e.g., a sidelink control channel) of the second RAT and determine an initial partition of the resources. The initial partition of the resources may indicate a quantity of resources to be used for transmissions by the first UE and the second UE. For example, a first group of the initial partition of the resources may be associated with the second RAT.

Abstract: Apparatus, methods, and computer-readable media for facilitating a SL communication for mode 2 resource allocation are disclosed herein. An example method includes configuring an inter-UE coordination message associated with sidelink communication with a second UE, the inter-UE coordination message indicating one or more resources for the sidelink communication. The example method further includes transmitting, to the second UE, the inter-UE coordination message via a MAC-CE, the MAC-CE being associated with a PSSCH. The example method further includes transmitting, to the second UE, or receiving, from the second UE, the sidelink communication via a first resource of the one or more resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from multiple UEs including a second UE, multiple sidelink control informations (SCIs). The UE may select, from multiple resource conflict indications derived from the multiple SCIs, a resource conflict indication based at least in part on a priority scheme. The UE may transmit, to at least one of the multiple UEs including the second UE, the resource conflict indication in accordance with a transmission power level. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a first user equipment (UE). The first UE selects one or more inter-UE coordination information messages based on at least one prioritization rule. The first UE then transmits the selected one or more inter-UE coordination information messages to at least a second UE via a sidelink.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, on one or more sidelink channels, a set of messages indicating a corresponding set of resource reservations. Accordingly, the first UE may transmit, to a second UE, a resource information message that indicates a subset of the set of resource reservations. The first UE may select the subset, from the set of resource reservations, using a time window, a maximum quantity of resource reservations, a retransmission threshold, a hop count threshold, a resource/subchannel threshold, or a combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first vehicle-to-every thing (V2X) device may receive, via a first radio access network (RAN), a scheduling assignment for a second V2X device. The first V2X device may decode the scheduling assignment to determine resource reservation information for the second V2X device on the first RAN. The first V2X device may modify at least one transmission associated with a second RAN based at least in part on the resource reservation information for the second V2X device on the first RAN. In some aspects, the first V2X device may transmit a coordination message for reception by one or more other V2X devices associated with a second RAN. The coordination message may include the resource reservation information for the second V2X device associated with the first RAN. Numerous other aspects are described.
