Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit first control information that is indicative of noise (e.g., phase noise, additive white gaussian noise (AWGN), or both) that impacts a spectral efficiency of a modulation and coding scheme (MCS). The MCS may be associated with a constellation of points that may be each representative of a respective candidate sequence of bit values encoded with a corresponding combination of signal amplitude and carrier phase. The UE may receive, based on transmitting the first control information, second control information that indicates a set of partitioning parameters indicative of a hierarchical partitioning of the constellation into a multiple subsets of points. As such, the UE may decode a message, modulated via the MCS, using the hierarchical partitioning indicated by the set of partitioning parameters.

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 user equipment (UE) may receive an indication of transmission spur frequency locations associated with transmissions of a network node. The UE may receive a communication from the network node, receiving the communication comprising performing one or more of channel estimation or noise estimation based at least in part on the transmission spur frequency locations. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may generate a waveform having an original amplitude. The transmitting device may reduce a peak portion of the original amplitude that is above a mirror level according to a reduction function that is based at least in part on a difference function associated with a difference between the mirror level and the peak portion, to obtain a reduced peak amplitude for the waveform. The transmitting device may transmit the waveform with the reduced peak amplitude. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication and to product codes for wireless communications. Some aspects more specifically relate to enabling a Bose-Chaudhuri-Hocquenghem (BCH) product code for wireless communications. In some aspects, a transmitter and/or a receiver may flexibly select parameters for a BCH product code based on or otherwise associated with communication parameters of a wireless communication to be encoded, such as the modulation and coding scheme (MCS) and/or allocation size, among other examples. For example, the transmitter and/or the receiver may select parameters for the BCH product code to ensure that the BCH product code is designed to handle a quantity of channel bits associated with a current configuration of a channel (for example, of an uplink data channel and/or a downlink data channel) and to increase a correction capability associated with the BCH product code for the current configuration of the channel.

Abstract: Aspects relate to using a reduced bandwidth for a retransmission of a first transmission, where the bandwidth reduction is based on acknowledgement information associated with the first transmission. For example, the amount of the bandwidth reduction may be based on the number of positive acknowledgements and/or negative acknowledgements sent by a UE in response to the first transmission. In some examples, the reduction in bandwidth may be applicable to a control search space and/or a data resource allocation.
