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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate, with a second UE, an indication relating to physical sidelink shared channel (PSSCH) beam training. The UE may transmit, to the second UE on symbols included in a transmission time interval, PSSCH data and beam training reference signals to be used by the second UE to perform beam measurements. Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for determining resources for sidelink communications based on coordination information. A method that may be performed by a first wireless device includes receiving, from second wireless devices, reports indicating coordination information associated with candidate resources and assigning ranks to the reports. The method also includes determining resources from the candidate resources for communicating with third wireless devices based on at least one of: at least two reports, and the ranks of the at least two reports; or at least one of the reports and sensing information, measured by the first wireless device, associated with the candidate resources, and the rank of the reports and a rank of the sensing information. The method further includes communicating with the third wireless devices via the determined resources.

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 wireless communication device may transmit, to a receiving device, an identification of a subset of code block groups (CBGs) of a set of CBGs, wherein the set of CBGs comprises a transport block; and transmit, to the receiving device, an initial data transmission comprising the subset of CBGs. Numerous other aspects are provided.
