Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in a vehicle-to-everything (V2X) system may receive configuration information from an assisting node, such as a roadside unit (RSU), for calculating location information for a target UE in the V2X system. The assisting node may reflect one or more radar signals from the UE towards the target, and from the target back towards the UE according to the configuration information. That is, the assisting node may modify one or more waveform parameters of the reflection according to the configuration information. The UE may calculate location information for the target based on the reflection, such as by classifying the target as non-line-of-sight (NLOS) based on modified waveform parameters, location information of the assisting node, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a control message indicating a set of interference measurement resources (IMRs) for reference signal transmission associated with radio link monitoring or beam failure monitoring. The first UE may receive, from a second UE via the set of IMRs, reference signals associated with radio link monitoring or beam failure monitoring based on the control message. The first UE may transmit, in response to receiving the reference signals, a beam failure report associated with the radio link monitoring or the beam failure monitoring based on one or more measurements of the one or more reference signals. In some examples, the beam failure report may indicate that beam failure is associated with cross-link interference (CLI) from the second UE.

In another aspect, a second UE receives, from a first UE, SCI and a PSSCH in a slot, the SCI being associated with a control message and the PSSCH being associated with a data message, and the SCI including an indication that the SCI and the PSSCH are decoupled in the slot. The second UE decodes the data message based at least in part on the indication.

The UE may transmit a beam report including an indication of the main lobe or the at least one side lobe associated with the directional beam causing the interference to the second beamformed transmission associated with the other directional beam from the base station.

Abstract: This disclosure provides methods, devices and systems for beamforming in wireless communications. Some implementations more specifically relate to beamforming configurations for multicast communications. A transmitting device may transmit multicast data to multiple receiving devices, concurrently, via a physical downlink shared channel (PDSCH). The PDSCH may be preceded by a physical downlink control channel (PDCCH). The PDCCH may provide scheduling information for the PDSCH, including a multicast beam associated with the PDSCH and a timing offset or delay between the PDCCH and the PDSCH. A receiving device may determine that the PDSCH contains multicast data based on an indication in the PDCCH. To receive the PDSCH, each receiving device may tune its antennas in a direction of the scheduled multicast beam or a default beam based on the delay between the PDCCH and the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify an applicable restricted resource scheduling rule for restricting full-duplex operation on a first set of resources. The base station may transmit one or more control messages scheduling one or more full-duplex communications on a second set of resources based on the applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources. In some examples, the second set of resources may overlap in time with the first set of resources. In other examples, the second set of resources may not overlap with the first set of resources in time or frequency. Accordingly, the base station may communicate the one or more full-duplex communications on the second set of resources. The described techniques may enable the base station to perform full-duplex communications with reduced interference and improved reliability.
