Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE) and a base station. The UE receives a configuration for a plurality of semi-persistent scheduling (SPS) occasions each SPS occasion including multiple opportunities for a downlink transmission by a base station. The UE monitors for the downlink transmission during one or more opportunities of an SPS occasion. The base station transmits a packet to the UE in an opportunity of an SPS occasion based on an arrival time of the packet. In various configurations, a base station may transmit first information via a first communication opportunity and second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

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: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics

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: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

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: Wireless communications systems and methods related to power saving over a forward link of a star topology of user equipment (UE) are provided. In some aspects, a first UE may monitor the forward link connecting a second UE to the first UE for a control message transmitted by the second UE to the first UE. The first UE may then establish an operational mode based on the result of the monitoring for the control message, such as but not limited to a power saving mode or an active mode.

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.
