Abstract: Certain aspects of the present disclosure provide techniques for reconfigurable intelligent surface-based interference cancellation. A method that may be performed by a network entity generally includes determining to perform interference cancellation with a reconfigurable intelligent surface (RIS) for interference that will occur at a first wireless node based at least in part on one or more criteria, wherein the interference includes an interfering signal that will be transmitted by a second wireless node; and performing the interference cancellation with reflections from the RIS in response to the determination.

Abstract: A transmitting user equipment (UE) may perform resource hopping for a periodic sidelink resource reservation by scheduling a plurality of periodic sidelink resources with a first periodicity, the plurality of periodic sidelink resources being shifted at a first offset in a frequency domain. The transmitting UE may reduce persistent collisions of periodic or semi-persistent scheduling (SPS) reservation of the sidelink resources with another UE. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) indicating the first offset and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI. The receiving UE may receive, from the transmitting UE, the SCI and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI.

Abstract: Aspects presented herein may enable one or more wireless devices to perform a sidelink-based ranging and/or positioning with an assistance of an RIS. In one aspect, a first wireless device receives an information indicating at least a time in which at least one RIS is to be activated. The first wireless device transmits a first set of reference signals to a second wireless device via the at least one RIS. The first wireless receives a second set of reference signals transmitted from the second wireless device via the at least one RIS. The first wireless calculates a first signal RTT based on the first set of reference signals and the second set of reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communication system support communications between user equipment (UEs). In the examples, a UE may include two or more transmission reception points (TRPs) and may transmit two or more packets on partially or fully overlapping resources via individual TRPs of the two or more TRPs. The UE may identify a first data packet for transmission using a first spatial layer associated with a first TRP and a second data packet for transmission using a second spatial layer associated with a second TRP. The UE may map a portion of the first data packet to a set of resources of the second spatial layer and transmitting a control message indicating that the portion of the first data packet is mapped to the second spatial layer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) with multiple transmission reception points (TRPs) (e.g., a multi-TRP UE) may receive sidelink control information including an interference measurement configuration indicating resources allocated for sidelink interference measurements across multiple TRPs. In some cases, the multi-TRP UE may decode the sidelink control information including the interference measurement configuration. The multi-TRP UE may receive one or more signals from a first UE, a second UE, or both. The multi-TRP UE may perform a sidelink interference measurement for each signal based on the interference measurement configuration. The multi-TRP UE may determine whether to process the signals in combination or separately across TRPs based on the sidelink interference measurements.

Abstract: Certain aspects of the present disclosure to techniques for sidelink re-discovery without repeating beamforming in millimeter wave (e.g., Frequency Range 2) bands. For example, a Tx UE may complete a first beam training with a Rx UE. The Tx UE may generate a discovery message that includes at least one of: an indication of a beam training reference signal (BT-RS) sequence index of the first beam training; an indication of a timer for changing the BT-RS sequence; or an indication of a second BT-RS sequence to be used by the Tx UE before an expiration of the timer. The second BT-RS sequence may be indicated as an index to a set of BT-RS sequences including the BT-RS sequence associated with the first beam training. The Tx may transmit the generated discovery message to the Rx UE.

Abstract: A method of wireless communication by a transmitting sidelink user equipment (UE) determines at least one quasi-co-location (QCL) relationship between antenna ports of the transmitting sidelink UE. The QCL relationship corresponds to carrier frequency offset (CFO), average delay, delay spread, Doppler shift, and/or Doppler spread across the antenna ports of the transmitting sidelink UE. Each port maps to a different transmission and reception point (TRP). The method also indicates the QCL relationship(s) to a receiving sidelink UE. A method of wireless communication by a receiving sidelink UE receives a message from TRPs of a transmitting sidelink UE. The message indicates a QCL assumption for the TRPs. The method also individually measures reference signals received from each transmission port of the TRPs. The method may also determine whether signaling from the TRPs satisfies all conditions for the QCL assumption, and report to the transmitting sidelink UE a result of the determining.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may communicate with one or more other UEs in accordance with a distributed resource allocation mode. To select suitable resources for an intended sidelink transmission, the first UE may transmit, to a second UE, a request for a type of coordination information based on information associated with the intended sidelink transmission from the first UE. The second UE may generate coordination information in accordance with the requested type and may transmit the coordination information to the first UE. The first UE may use the coordination information to select a set of resources over which to perform the intended sidelink transmission from the first UE and may perform the intended sidelink transmission over the selected set of resources.

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.
