Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device, such as a user equipment (UE), may be configured to communicate with one or more other wireless devices (e.g., another UE) via sidelink communications. The first wireless device may receive an indication of a schedule of resources for sidelink communications to be performed over a communication beam, the schedule indicating a set of resources corresponding to a beam configuration for the sidelink communications with a second wireless device. The first wireless device may communicate with the second wireless device via one or more sidelink channels based on configuring the communication beam using the beam configuration over the set of resources. In some examples, the indication of the schedule of resources may be received in a confirmation of the schedule established by the second wireless device or, in some examples, in a request to establish the schedule.

Abstract: A method of wireless communication includes identifying, by a first node configured for operation in a synchronous communication mode, a current synchronization boundary according to a common clock of the synchronous communication mode. The method further includes performing, by the first node, a common clock-triggered (CCT) listen before talk (LBT) procedure of a shared communication channel during a periodic quiet interval at the current synchronization boundary. The method further includes establishing, by the first node, in response to success of the CCT LBT procedure, a channel occupancy time (COT) configured to end at a subsequent synchronization boundary and transmitting, by the first node, data on the shared communication channel during the COT.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (base station or UE) may receive an indication of a listen before talk (LBT) gap for sharing a channel occupancy time (COT), the COT being acquired by another wireless device (base station or UE), and detect whether a slot within the COT is occupied by the other wireless device, the slot occurring prior to the LBT gap. The wireless device may also, responsive to detecting that the slot is occupied by the other wireless device, perform an LBT procedure during the LBT gap, and, responsive to a successful LBT procedure, transmit a signal to the other wireless device within the COT.

Abstract: Methods, systems, and devices for wireless communications are described. A sidelink message may be scheduled for a UE during a first short transmission time interval (TTI). The first short TTI and a second short TTI for transmitting a sidelink feedback message corresponding to the sidelink message may both be shorter in duration than a another, longer type of TTI. The UE may transmit automatic gain control information in a first symbol period of the second TTI, transmit the sidelink feedback message in a second symbol period of the second TTI (after the first symbol period of the second TTI), and switch from operating in a transmitting mode to operating in a receiving mode during a third symbol period of the second TTI (after the second symbol period of the second TTI).

Abstract: Enhanced measurements for new radio-unlicensed (NR-U) operations are disclosed. Compatible user equipments (UEs) may be configured to perform virtual full listen before talk (LBT) procedures for measurement purposes. The UEs may then compile LBT statistics derived from the virtual LBT procedures and include such statistics in an enhanced measurement report the their serving base stations. The LBT statistics provide a more direct and detailed reflection of the usage of a shared communication channel. Such UEs may further be configured to gather additional LBT statistics from transmission-based LBT procedures in addition to the virtual LBT procedures. The additional direct and detailed usage of a shared channel may then be provided in the enhanced measurement reports in accordance with described aspects.

Abstract: Wireless communications systems and methods related to multi-hop sidelink are provided. In one aspect, a first user equipment (UE) receives, from a base station (BS), a configured grant (CG) indicating a first CG occasion. The first CG occasion includes a first transmit resource and a first receive window. The first UE receives, from a second UE in the first receive window, a first communication signal including a first data block. The first UE transmits, to a third UE in the first transmit resource, a second communication signal including the first data block.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit a stage one sidelink control information (SCI) message to multiple receiver UEs. In some aspects, the stage one SCI message may indicate respective resource reservations for multiple sidelink transmissions to the multiple receiver UEs. The transmitter UE may transmit a physical sidelink shared channel (PSSCH) to a subset of the multiple receiver UEs based at least in part on a configured grant associated with the subset of the multiple receiver UEs and the respective resource reservations indicated in the stage one SCI message. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for qualifying machine learning model-based channel state information (CSI) predictions. An example method generally includes receiving, from a network entity, a channel state information (CSI) prediction model for quantized CSI, calculating CSI based on downlink reference signal measurements, generating a quantized CSI difference value based a quantization of a difference between the calculated CSI and CSI predicted based on a CSI prediction model, and reporting, to the network entity, the calculated CSI and the quantized CSI difference value.
