Abstract: Methods, systems, and devices for wireless communications are described in which a first user equipment (UE) may transmit a first communication to a second UE during a first channel occupancy time (COT). The first UE may reserve resources of one or more subsequent COTs for one or more repetitions of the first communication. The reserved resources may be identified based at least in part on a two stage resource reservation, in which reserved resources are identified relative to a timing of the one or more subsequent COTs. Such a UE may first determine a timing of a second COT and may then determine a timing of the reserved resources based on the timing of the second COT. The reserved resources may be identified based at least in part on one or more offsets from a starting time of the second COT.

Abstract: Methods, systems, and devices for wireless communication are described in which a user equipment (UE) may transmit one or more uplink communications to multiple transmission-reception points (TRPs). Transmission parameters for each repetition may be based on parameters (e.g., a number of antenna ports, a spatial domain filter or beam, a rank or number of layers, or any combinations thereof) that are determined from an indication of whether the repetitions are to use different sounding reference signal (SRS) resource sets, and indicated SRS resource of each SRS resource set. The indication may include a same number of bits regardless of whether one SRS resource set is used or multiple SRS resource sets are used, and may be based on a prior configuration of the UE.

Abstract: Apparatus, methods, and computer-readable media for facilitating reference signal multiplexing with downlink data are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving, from a base station, a reference signal configuration associated with at least one of a tracking reference signal (TRS) and a channel state information reference signal (CSI-RS), the reference signal configuration comprising a symbol level rate matching configuration, a precoder configuration, or a guard tone configuration. The example method also includes receiving, from the base station, a transmission comprising at least a reference signal and data based on the reference signal configuration.

Abstract: Methods, systems, and devices for wireless communications are described to support resource block (RB) grid alignment at user equipments (UE) in sidelink communications. In a first example, communicating UEs may support different RB grids and a receiving UE may attempt multiple decoding hypotheses for receiving a sidelink control channel from a transmitting UE, where each hypothesis may correspond to a different RB grid. In a second example, an RB grid for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the sidelink control channel using the common RB grid. In a third example, demodulation reference signals (DMRSs) and resource element (RE) rate matching for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the control channel using the aligned DMRSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration communication associated with a first shared channel communication that includes a first demodulation reference signal (DMRS) having a first configurable DMRS lifespan, wherein the first configuration communication comprises a DMRS sharing indication associated with reuse of the first DMRS associated with a second shared channel communication. The UE may receive the first shared channel communication. The UE may receive the second shared channel communication based at least in part on the DMRS sharing indication. Numerous other aspects are described.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

Abstract: A user equipment (UE) includes a receiver configured to receive, during operation based on a first mode, a configuration message from a base station. The configuration message indicates sidelink resources associated with a sidelink data channel. The UE further includes a transmitter configured to transmit, based on detecting that one or more conditions associated with the configuration message are satisfied, and during operation based on a second mode, a sidelink message to a second UE via the sidelink data channel during an occasion associated with the sidelink resources.

Abstract: A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.
