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 one aspect, resource selection may be performed where single frequency full-duplex (SFFD) UEs are present in a V2X system. Signaling and procedures may enable the coexistence of half-duplex (HD) and SFFD-capable UEs. Based on the resource reservation information obtained from other UEs, the SFFD UE may determine which among the reserved time-frequency resources is amenable for performing the SFFD operation. In one aspect, the time-frequency resources chosen for SFFD may partially or fully overlap with the reserved time-frequency resources, based on the self-interference cancellation capability of the SFFD UE, the RSRP, and/or the RSSI on the reserved time-frequency resources. Accordingly, the full-duplex capability of an SFFD-capable UE may be leveraged, and spectral efficiency improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first vehicle user equipment (VUE) may transmit, to a node, first information associated with a presence of an object in a region of interest based at least in part on a sensing of the region of interest performed by the first VUE. The VUE may receive, from the node, second information associated with the presence of the object in the region of interest based at least in part on a sensing of the region of interest performed by a second VUE. The VUE may determine whether the object is present in the region of interest based at least in part on the first information and the second information. The VUE may perform an action based at least in part on whether the object is present in the region of interest. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an initiator UE, a group formation communication indicating a group that the UE is associated with for a group positioning reference signal (PRS) Listen Before Talk (LBT) procedure. The UE may transmit, to the initiator UE, an indication that the UE should not be associated with the group based at least in part on performing the group PRS LBT procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may receive, from a second WCD, transmission configuration indicator (TCI) state information that defines a set of TCI state configurations for a full duplex operation, wherein TCI state configurations of the set of TCI state configurations are associated with respective receive beams and respective transmit beams. The WCD may transmit, to the second WCD, an indication of one or more candidate TCI states, associated with the set of TCI state configurations, for selection by the second WCD for communications using the full duplex operation. Numerous other aspects are provided.

Abstract: Techniques are provided for sidelink positioning with a single anchor using distributed antenna systems. An example method for determining relative locations of two stations includes determining a first round trip time for positioning reference signals transmitted between a first station and a first antenna of a second station, determining a second round trip time for the positioning reference signals transmitted between the first station and a second antenna of the second station, wherein the first antenna and the second antenna are disposed in different locations proximate to the second station, and determining relative locations of the first station and the second station based at least in part on the first round trip time and the second round trip time.
