Abstract: Apparatus, methods, and computer-readable media for facilitating multiplexing SCI-only grant and data-only SPS traffic on sidelink are disclosed herein. An example method for wireless communication at a first UE includes transmitting a sidelink transmission to a second UE at a first resource, the sidelink transmission including data-only traffic and scheduling information corresponding to future data traffic. The example method also includes transmitting a time offset indicator indicating a starting resource of the future data traffic.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

Abstract: Certain aspects of the present disclosure provide techniques for improving positioning accuracy of user equipments (UEs) using non line-of-sight (NLOS) positioning reference signals (PRS) and map information. A method that may be performed by a UE includes obtaining map information regarding, at least, one or more reflectors in an environment including at least the UE and another node, detecting at least one positioning reference signal (PRS) transmission that travels one or more non line-of-sight (NLOS) transmission paths in the environment, and participating in a positioning procedure that estimates a position of the UE based, at least in part, on the at least one PRS transmission that travels the one or more NLOS transmission paths and the map information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from at least one second UE, first control information associated with a first reserved set of resources on a sidelink channel. The first UE may attempt to decode additional control information based at least in part on the first control information. The first UE may transmit, based at least in part on failing to decode the additional control information, a message using the first reserved set of resources. In some aspects, the first UE may determine, based on one or more resource dimensions, at least one first distance between the first UE and the at least one second UE, such that the message is transmitted with a first transmit power based at least in part on the first distance. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications in order to minimize the number of subchannels that a receiver (e.g., PLC or SA) may need to blind decode. More particularly, the search space is configurable based on a hashing function that is based in part on a portion of the resources (e.g., PLC resources) that have been allocated or reserved for sidelink communication within the PLC subnetwork (or PLC group) from the sidelink resource pool available to a plurality of PLCs in a network. By limiting the search space to a subset of resources that are specific to the PLC subnetwork or group, the need for the SA or PLC to perform blind decoding of sidelink control information (SCI) may be further reduced.

Abstract: Apparatus, methods, and computer-readable media for facilitating usage of memory of helping UEs during sidelink retransmission are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a wireless device, a first packet and a second packet for sidelink retransmission to at least one second UE, the second packet being received after the first packet. The example method also includes dropping the first packet or the second packet prior to retransmission based on at least one of a packet priority or an indication from the wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for a fallback retransmission for a sidelink. A method that may be performed by a user equipment (UE) includes monitoring a transmission from a node. The UE can determine that the transmission was not successfully decoded. The UE can send a feedback message to the node indicating that the transmission was not successfully decoded. The feedback message can also include an indication of whether the node or a base station (BS) retransmits the transmission. The node retransmits the transmission or indicates to the BS to retransmit based on the feedback message. The BS can configure the node, the UE, or both with one or more thresholds for determining whether the node or the BS retransmits the transmission.

Abstract: Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.
