    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit neural network (NN) capability information to a network entity. The network entity may train the NN model by selecting a NN-based precoder and generating associated coefficients. The network entity may transmit an indication of the precoder coefficients to the UE. The network entity may transmit demodulation reference signals (DMRSs) that have not been precoded and a physical downlink shared channel (PDSCH) signal that has been narrowband-precoded according to the indicated precoder. The UE may then perform and input a channel estimation to the NN model. The NN model may output the narrowband precoder, which the UE may use to generate a narrowband channel estimate and demodulate the narrowband precoded PDSCH signal. In some examples, the network entity may update NN coefficients and may indicate the updated NN coefficients to the UE.

    Abstract: Aspects described herein relate to processing synchronization signal block (SSB) signals and/or corresponding system information block (SIB) based on whether the SSB is received directly from a network node or from a router in a path from the network node. For example, a signal originated from a network node can be received. It can be determined whether the SSB is received from the network node or from a router in a path from the network node, and the SSB or a corresponding system information block (SIB) of the network node can be processed based on whether the SSB is received from the network node or the router. Other aspects relate to indicating whether a SSB is from a network node or a router in the path.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support noise indicator intermediated signal demodulation. An apparatus for wireless communication may include a communication interface configured to receive a noise indicator that indicates a transmitter noise associated with a transmitter. Additionally, the apparatus may include a processor system configured to demodulate, based on a noise covariance matrix, a signal received from the transmitter. The noise covariance matrix may be based on the noise indicator.

    Abstract: Methods, systems, and devices for wireless communications are described. A first device may transmit, from a first antenna of a first antenna array of the first device to a second antenna of a second antenna array of a second device, a first set of reference signals. The first device may transmit, from a first plurality of antennas of the first antenna array to a second plurality of antennas of the second antenna array, a second plurality of reference signals. The first device may receive, from the second device, an indication based at least in part on a linear offset and one or more rotational offsets estimated by the second device associated with the first set of reference signals and the second plurality of reference signals. The first device may communicate with the second device using the first antenna array based on the indication.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit a first signal using a first antenna of the antenna array, the antenna array having a plurality of antennas that are arranged along a curved structure, wherein the curved structure is convex in a direction opposite a transmission direction, and wherein the first antenna is located at a first position on the curved structure so that the first signal has a first aperture with respect to the lens. The first network node may transmit a second signal using a second antenna of the plurality of antennas, wherein the second antenna is located at a second position on the curved structure so that the second signal has a second aperture with respect to the lens. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive reference signals for a UE beam measurement procedure for measuring a set of network transmit beams corresponding to the set of reference signals. The UE may transmit a measurement report indicating measurements of the set of reference signals based on the UE beam measurement procedure, where the measurement report further includes an indication of one or more candidate network transmit beams that are additional to the set of network transmit beams and that are within an angular offset threshold from one or more network transmit beams of the set of network transmit beams. In response to transmitting the measurement report, the UE may receive a message indicating a configuration for communications with the network entity.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report an initial capability to maintain latency conditions and a number of supported beams (e.g., a threshold number of beams the UE can support for relaying downlink communications such as synchronization signal blocks (SSBs)). A network entity may then transmit multiple SSBs directly to the repeater (e.g., on the same beam). The repeater may relay the SSBs across multiple beams to provide service to a coverage area. After relaying signaling between served UEs and the network entity, the repeater may transmit a report requesting a specific (e.g., improved or more accurate) number of beams (e.g., more beams or fewer beams than the number of SSBs initially provided). Upon receiving an updated configuration of a number of beams, the repeater may receive more SSBs on a single beam, and relay SSBs on the updated number of beams.
