Abstract: Methods, apparatuses, and computer-readable medium for soft cancellation of sidelink transmissions are provided. An example method may include receiving, from a base station, DCI comprising at least one of: an open loop power control parameter, a maximum transmit power, or a closed loop power control parameter. The open loop power control parameter, the maximum transmit power, or the closed loop power control parameter may be associated with a PSSCH or a PSCCH. The example method may further include reducing a transmit power of a scheduled transmission associated with the PSSCH or the PSCCH to a reduced transmit power if the reduced transmit power is above a threshold or cancel the scheduled transmission if the reduced transmit power is below the threshold. The reduced transmit power may be based on the open loop power control parameter, the maximum transmit power, or the closed loop power control parameter.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: A first UE may select, based on a resource pool configuration for a sidelink communication, at least one of a first slot in time or a second slot in time of a plurality of slots. The plurality of slots may be associated with DMRS bundling. The first UE may configure, based on the DMRS bundling, at least one of one or more symbols in the first slot in time from a gap symbol to a non-gap symbol or one or more symbols in the second slot in time from an AGC symbol to a non-AGC symbol. The first UE may transmit, to a second UE, an indication of the configuration of the at least one of the one or more symbols in the first slot in time or the one or more symbols in the second slot in time.

Abstract: Apparatus, methods, and computer-readable media for facilitating support for an increased quantity of sidelink configured grants are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling information corresponding to a first quantity of sidelink configured grants, the first quantity of sidelink configured grants being greater than eight sidelink configured grants. The example method also includes receiving, from a base station, an activation of a sidelink configured grant of the first quantity of sidelink configured grants. The example method also includes transmitting sidelink traffic to a second UE based on the sidelink configured grant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates multiple time intervals corresponding to multiple physical sidelink shared channels (PSSCHs) within a slot, wherein at least one PSSCH, of the multiple PSSCHs, starts in a symbol other than an initial data symbol of the slot. The UE may communicate in one or more PSSCHs, of the multiple PSSCHs, within the slot based at least in part on the configuration. Numerous other aspects are described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a sidelink coverage extension using repeated transmission. A first UE may transmit a multiple slot SCI in a first slot of a group of multiple slots for reserving resources for the group of multiple slots and transmitting one or more sidelink transmissions in the reserved resources. A second UE may receive the multiple slot SCI in the first slot of the group of multiple slots for receiving the one or more sidelink transmissions in the reserved resources for the group of multiple slots. In aspects, a base station may receive configuration parameters for the multiple slot SCI and configure one or more UEs with a multiple slot configuration, based on the configuration parameters, for transmitting/receiving the multiple slot SCI associated with the reserved resources in the group of multiple slots.

Abstract: Aspects presented herein may enable a sidelink device to report or to receive HARQ feedback for sidelink channels based on a long PSFCH format. In one aspect, an apparatus transmits, to a second UE, an indication to provide HARQ feedback for at least one sidelink channel. The apparatus transmits, to the second UE, the at least one sidelink channel. The apparatus receives, from the second UE, an ACK or a NACK for the at least one sidelink channel via a PSFCH, the PSFCH including a long PSFCH format and associated with a sidelink resource pool.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for CRC scrambling for SCI in sidelink communication. A wireless transmitter may be configured to scramble bits of SCI based on a scrambling sequence and transmit the SCI to a wireless receiver. The wireless receiver may receive the SCI having CRC bits scrambled with the scrambling sequence and attempt to decode the SCI, including descrambling the CRC bits of the SCI. The SCI may include a first portion of SCI transmitted in a PSCCH and a second portion of SCI transmitted in a PSSCH.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for reverse sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications. Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) for reception of sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) that may be received at the PLC from the one or more SAs. In some examples, the PLC may monitor the subset of subchannels and decode the sidelink packets received on the subset of subchannels without the need for the PLC to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless node (e.g., which may be a programmable logic controller (PLC), a central node, a sidelink user equipment (UE), or the like) may communicate with a base station via a first wireless communication link and with another UE (e.g., a sensor/actuator (S/A), a child node, another sidelink UE, or the like) via a second wireless communications link. The wireless node may receive, from the base station via the first wireless communication link, a grant of resources associated with the second wireless communication link, where the grant of resources is encoded with a shared radio network temporary identifier (RNTI) that is shared by both the wireless node and the UE. The wireless node may determine, based at least in part on the shared RNTI, that the grant of resources is for the UE, and forward the grant to the UE.
