Abstract: Methods, systems, and devices for wireless communications are described that provide machine-learning models, such as neural network (NN) based precoding functions, that may be used at a user equipment (UE) to determine precoding parameters directly based on channel estimations performed at the UE. A network entity may measure a channel used for communications with the UE and determine coefficients that are to be applied to a machine learning precoding function (e.g., a NN precoding function) at the UE. The network entity may provide the determined coefficients to the UE. The UE may use the indicated coefficients in the NN based precoding function, along with a channel estimation of a channel associated with an uplink transmission, to determine a precoding matrix that is to be applied for the uplink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from a parent network node, an indication of a mapping of time and frequency resources to a set of beams of the network node. The network node may receive one or more communications for forwarding via the set of beams using a set of time and frequency resources. The network node may forward the one or more communications via one or more beams of the set of beams based at least in part on the one or more communications being associated with the set of time and frequency resources, the set of time and frequency resources being mapped to the one or more beams according to the mapping of the time and frequency resources to the set of beams of the network node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a slot based at least in part on a transmit beam, wherein the slot is associated with a plurality of slot repetitions using different transmit beams. The UE may transmit, to the network node in the slot and based at least in part on a metric associated with a beam pair satisfying a threshold, feedback to early terminate remaining slot repetitions of the plurality of slot repetitions using the different transmit beams. Numerous other aspects are described.

Abstract: Aspects relate to transmission configuration indicator (TCI) state configuration in multi-stream communication between a radio access network (RAN) entity and a user equipment (UE). The UE may obtain a respective beam quality metric for each transmit beam of a plurality of transmit beams associated with the RAN entity and transmit a beam report to the RAN entity including a respective beam quality metric for each of the transmit beams. The RAN entity may then group the plurality of transmit beams into a plurality of beam groups based on the beam report and transmit a plurality of TCI state groups, each corresponding to a respective one of the beam groups, to the UE.

Abstract: Wireless communications systems and methods related to reducing the signaling overhead for configuring a common reference signal used in performing coarse power control of multiple spatial domain multiplexing (SDM) uplink streams are provided. A base station may be in communication with a UE via multiple SDM streams directed from the same panel of the respective device. The base station may configure a common pathloss reference signal for the SDM streams of the same panel for the UE. This may include sending a list of possible pathloss reference signal configurations to the UE, and then identifying which configuration to use for the pathloss reference signal for the group of SDM streams. Once known, the UE may measure the reference signal for open loop power control. The BS may occasionally reconfigure the common reference signal for the grouped SDM streams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an encoded communication, the encoded communication being encoded with a hierarchical coding scheme comprising: first layer code blocks including pairs of information bits and sets of first parity bits, and second layer code blocks including sets of second parity bits, with each set of the second parity bits associated with a subset of the first layer code blocks. The wireless communication device may decode the encoded communication based at least in part on one or more of the sets of the second parity bits that are associated with one or more of the first layer code blocks determined to have failed decoding based at least in part on one or more associated sets of the first parity bits. Numerous other aspects are described.

Abstract: A first UE may transmit, to a second subset of one or more second UEs, one or more pilot signals associated with DPD training. The first UE may receive, from a third subset of the one or more second UEs, one or more feedback messages associated with DPD training. The one or more feedback messages may be based on the one or more pilot signals. Each second UE in the third subset of the one or more second UEs may correspond to one of the one or more feedback messages. The second UE may calculate one or more DPD parameters based on the one or more feedback messages. The second UE may transmit a first signal based on the calculated one or more DPD parameters.

Abstract: Apparatus, methods, and computer-readable media are disclosed herein for facilitating spatial misalignment tracking for OAM beams in millimeter wave and higher frequency bands. An example method for wireless communication at a first communication device includes receiving, from a second communication device, a first misalignment tracking RS and a second misalignment tracking RS for an OAM transmission. The example method also includes determining a misalignment based on the first misalignment tracking RS, the second misalignment tracking RS, and using a subset of antenna elements of an antenna array of the first communication device. Additionally, the example method includes adjusting reception of a subsequent OAM transmission from the second communication device at the antenna array of the first communication device.

Abstract: Aspects presented herein may enable a receiving device to receive high frequency signals with a simpler receiver to reduce the overall complexity and cost associated with the receiver. In one aspect, an apparatus receives a reference signal from a second wireless device. The apparatus measures amplitude and phase of the reference signal relative to a set point. The apparatus transmits channel flattening information in a precoding feedback to the second wireless device, the precoding feedback including at least a difference between the amplitude of the reference signal and the set point for a sub-band.
