Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for sidelink FR2 beam alignment over data slots. A first UE may determine that a BPL with a second UE has degraded below a threshold and generate, based on the determination, a beam training frame for an on-demand beam training procedure. The beam training frame may include a first AGC symbol, SCI indicating that the beam training frame is for beam training, and one or more sets of an AGC symbol and beam sweeping reference signals. The first UE may transmit the beam training frame multiplexed with one or more data frames to the second UE. The second UE may receive the beam training frame for the on-demand beam training procedure based on a determination that the BPL with the first UE has degraded below the threshold.

Abstract: In some aspects, a method of wireless communication includes performing a full reference signal receive power (RSRP) sweep for a first slot to determine a first resource exclusion RSRP threshold, and performing a resource reevaluation for a second slot based on the first resource exclusion RSRP threshold from the first slot. In some aspects, a method of wireless communication may include performing a full RSRP sweep for a first slot to determine a first resource exclusion RSRP threshold and performing the full RSRP sweep for a second slot that is a number of slots following the first slot to determine a second resource exclusion RSRP threshold. For each slot between the first slot and the second slot, the resource reevaluation may be performed based on the first resource exclusion RSRP threshold determined for the first slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical sidelink feedback channel (PSFCH) transmission associated with a semi-persistent scheduling (SPS) grant. The UE may transmit an indication of a removal of a resource associated with the SPS grant, wherein the removal of the resource is based at least in part on a signal power associated with the PSFCH transmission satisfying a signal power threshold. Numerous other aspects are described.

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.
