Abstract: A UE receives, from a network entity, control information scheduling a downlink transmission and indicating a first feedback resource for a first decoding scheme of the UE and a second feedback resource for a second decoding scheme of the UE. The UE may receive a downlink transmission from the network entity. The UE may decode the downlink transmission using at least one of the first decoding scheme or the second decoding scheme. The UE may transmit, to the network entity, a first ACK/NACK response based on the decoded downlink transmission. The UE may transmit the first ACK/NACK response using the first feedback resource if decoding the downlink transmission using the first decoding scheme. The UE may transmit the first ACK/NACK response using the second feedback resource if decoding the downlink transmission using the second decoding scheme.

Abstract: A first UE may receive, from a base station or a second UE, one or more first TCI states via RRC signaling. The first UE may receive, from the base station or the second UE, one or more MAC-CEs. Each of the one or more MAC-CEs may include at least one indication of one or more second TCI states. The one or more second TCI states may be a subset of the one or more first TCI states. The first UE may transmit to the second UE, or receive from the second UE, a sidelink message via a sidelink channel based on a third TCI state. The third TCI state may be from the one or more second TCI states.

Abstract: A user equipment (UE) communicates with a network node based on a first transmission configuration indication (TCI) state. The UE receives control information indicating a second TCI state from a TCI candidate set that comprises a list of TCI states that can be activated for future communication, the TCI candidate set including a first set of TCI states associated with the first TCI state. The UE updates, in response to receiving the control information indicating the second TCI state, the TCI candidate set to include a second set of TCI states that have a second association with the second TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit a polling request to a receiving device in sidelink control information that is associated with a sidelink data transmission. The polling request may be included in a sidelink control information message or in a medium access control layer message. The receiving device may respond to the polling request with an indication of whether there is data available for transmission to the transmitting device at the receiving device. The transmitting device may determine whether to schedule reverse sidelink resources for the receiving device to transmit the available data based on the response to the polling request.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive, from a second wireless device and over a plurality of different beams, a set of reference signals as part of a beam management procedure. The first wireless device may select one or more bit values for indicating to the second wireless device a corresponding one or more individual beams of the plurality of different beams for communications between the first wireless device and the second wireless device, the one or more bit values selected based on a distribution of probabilities for switching between the plurality of different beams for the communications between the first wireless device and the second wireless device. The first wireless device may transmit control signaling indicating a ranking of the one or more individual beams for the communications between the first wireless device and the second wireless device.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a sidelink communication link for performing one or more sidelink communications with a second UE. The UE may transmit, to the second UE via the sidelink communication link as part of a beam management procedure, a first reference signal using a first beam over a first symbol of a sidelink slot, and a second reference signal using a second beam over a second symbol of the sidelink slot, and may communicate with the second UE using the first beam in accordance with the transmission. The UE may also transmit, over one or more third symbols of the sidelink slot using a third beam at a power level, a gain control signal. The second UE may perform measurements in accordance with the transmission, and may transmit a signal indicating one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more measurement parameters associated with a set of reference signals. The UE may receive a first reference signal associated with a first measurement value and second reference signal associated with a second measurement value. The UE may transmit a measurement report based on the one or more reporting parameters and in accordance with a reporting option selected from a set of reporting options for the measurement report. The set of reporting options may include an absolute reporting option and a quantized reporting option. In some examples, the UE may receive a bit value indicating which reporting option to use for one or more measurement reports. In some examples, the UE may perform both reporting options and choose the reporting option associated with a lower error.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may identify one or more measurement parameters to use for input in a machine learning (ML) model. In some cases, the measurement parameters may include reference signal received power measurements or a past set of timing advance (TA) values for a specific node. The UE may predict the TA based on inputting the measurement parameters into the ML model. The UE may transmit an uplink communication from the UE to a network entity using the TA predicted from the ML model. In some examples, the UE may transmit a capability report to indicate that the UE may support autonomous update of the TA based on the predictions of the TA values produced from the ML model.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a sidelink resource configuration for a slot, wherein the sidelink resource configuration includes a first set of resources carrying a first PSSCH in a first mini-slot of the slot, a second set of resources carrying a second PSSCH in a second mini-slot of the slot, and a third set of resources carrying a PSFCH associated with one or more PSSCHs of one or more preceding slots. The UE may communicate data over at least a portion of the slot in accordance with the sidelink resource configuration. In some designs, a sidelink management device (e.g., the UE, another UE, or a network component) may transmit the sidelink resource configuration.
