Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a request for a data transmission that includes multiple subsets of data each associated with a different constellation granularity. In response to the request, the base station may encode the data transmission using multiple different constellation granularities and may transit the encoded data transmission to the UE. For example, the UE may receive the data transmission including a first subset of data that was encoded by the base station using a first constellation granularity and a second subset of data that was encoded by the base station using a second constellation granularity. The UE may then iteratively estimate phase-noises associated with respective subsets of data and perform phase-noise correction operations on the entire data transmission based on the estimated phase-noises.

Abstract: Aspects are provided which allow for a network entity such as a base station to configure odd modulation orders to be applied to downlink or uplink transmissions via signaling between the network entity and the UE. Initially, the network entity transmits a configuration to the UE indicating network support for communications using odd order modulation. Afterwards, the UE transmits, and the network entity receives, data in a signal using the odd order modulation. As a result, improved SPEF, PAPR reduction, and phase noise mitigation associated with odd order modulations may be realized through application of odd order modulations to data transmissions or receptions based on network support being configured for such odd order modulations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a precoding operation to a downlink physical channel. The network node may obtain a plurality of coefficients associated with a non-linearity of the downlink physical channel in accordance with estimating a cross-correlation of a plurality of power delay profiles associated with the precoding operation. The network node may precode a physical downlink shared channel communication in accordance with a result of the precoding operation. The network node may transmit the plurality of coefficients via a physical downlink control channel communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a set of data resource elements for transmitting data in one or more symbols periods. The first wireless device may generate, for the one or more symbol periods based on the set of data resource elements, a sequence of a set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements including a demodulation reference signal. The first wireless device may transmit, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements. The second wireless device may decode a first subset of the set of pilot resource elements based on a second subset of the set of pilot resource elements to determine the demodulation reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may select a scrambling sequence to use per symbol to reduce variance in a non-linearity parameter for a power amplifier (PA) output between a data symbol and a pilot symbol based on a PA model for at least one pilot symbol or one or more parameters of the model. The receiving device may indicate a capability to blindly estimate the scrambling sequence the transmitting device selected to the transmitting device. If the transmitting device does not receive the capability message from the receiving device or if the capability message indicates the receiving device is not capable of blind estimation, the transmitting device may indicate the selected scrambling sequence to the receiving device. Otherwise, the transmitting device may not indicate the selected scrambling sequence to the receiving device, and the receiving device may blindly estimate the scrambling sequence.
