Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a first UE. The method includes receiving a data transmission from a second UE. The data transmission is associated with a feedback procedure for data transmissions that is based on a distance between the first UE and a transmitting UE. When the first UE (i) cannot successfully decode the data transmission and (ii) cannot determine the distance between the first UE and the second UE, the method includes determining whether one or more criteria are satisfied for sending, to the second UE, a negative acknowledgement (NACK) for the data transmission as part of the feedback procedure, where the NACK indicates the first UE could not successfully decode the data transmission. The method including transmitting the NACK to the second UE when the one or more criteria are satisfied.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for channel and/or resource selection for sidelink communications. In some cases, a transmitter user equipment UE may transmit, on a sidelink channel used for communicating with other UEs, a control message indicating at least one range, monitor for feedback associated with detection of the control message by one or more other UEs within the indicated range, and transmit data if the feedback indicates at least that the sidelink channel is free.

Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.

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: Methods, systems, and devices for wireless communications are described. A first network coding device may determine to hand over retransmission of a packet (e.g., the task of retransmitting the packet) to a second network coding device, and the first network coding device may use the techniques described herein to perform the handover. In one aspect, the first network coding device may transmit a negative acknowledgment (NACK) to a user equipment (UE) that originally transmitted the packet, and the UE may transmit a request for any of one or more network coding devices to take over retransmission of the packet. In another aspect, the first network coding device may transmit a request for any of one or more network coding devices to take over retransmission of the packet.

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. A target user equipment (UE) may receive an indication of a session key from an initiator UE in a sidelink communications system, from a network entity (e.g., a base station), or the like. In some cases, the target UE may also receive an indication of a nonce in a message of a PRS procedure. The target UE may select a positioning reference signal (PRS) sequence for the PRS procedure using the session key and optionally the nonce, such as by using a defined function at the target UE with the session key and the nonce as an input. Once the target UE selects the PRS sequence, the target UE may encode the PRS sequence and may transmit the PRS sequence to the initiator UE.

Abstract: A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.
