Methods and devices for transmission symbol modulation that accounts for distortion introduced by a power amplifier (PA). A user equipment (UE) comprises a transceiver and a processor. The transceiver is configured to transmit, to a base station (BS), UE capability information that indicates support for adjusted symbol constellations, wherein the adjusted symbol constellations are adjusted to pre-compensate for distortion effects of a power amplifier (PA) in the transceiver, and receive, from the BS, a modulation and coding scheme (MCS) indication. The processor is configured to determine, based on the MCS indication, an adjusted symbol constellation, and generate modulation symbols from input bits according to the determined adjusted symbol constellation. The transceiver is further configured to transmit, to the BS, the modulation symbols.

Support of power amplifier-aware modulation

Error-correcting performance of polar codes is improved by assigning parity check bits to small, reliable indices. Zeros are assigned to message indices not among a most-reliable set of the message indices, information bits and parity check bits are assigned to the most-reliable set of the message indices, with the parity check bits generated on the information bits assigned to the smallest of the most-reliable set and then assigned to the smallest indices of the most-reliable set that follow the information bits on which the parity check pits are generated. During successive cancellation list decoding, the parity check bits allow error events to be promptly corrected during decoding.

Method for polar code design with parity check bits

Methods and apparatuses in a wireless communication system for a user equipment (UE) to perform a power management method. The method includes receiving, by the UE, one or more power parameters for a non-terrestrial network (NTN). The method also includes selecting a power management method from one of: a predictive transmit power method based on time and the distance between the UE and an NTN entity or a non-predictive transmit power method. The method also includes determining a power based on the power management method and the power management parameters. The method further includes transmitting a signal to the reception point using the power.

Sparsity assisted channel state information (CSI) reporting or two-step CSI reporting is enabled or disabled for a user equipment. The configuration enabling/disabling sparsity assisted truncation for CSI reporting or two-step CSI reporting includes a domain for transformation of CSI for the sparsity assisted CSI reporting, and a time window for correlated channel. When the configuration enables sparsity assisted truncation for CSI reporting, a fixed number of non-zero coefficients and one or more threshold values for delay/angle or doppler for truncation are configured. When sparsity assisted truncation for CSI reporting is enabled, received the CSI reference signals are measured based on the configuration and a CSI report is transmitted indicating a specific range for which truncation occurred. When two-step CSI reporting is enabled, CSI compression corresponding to the at least one configuration and the time window is performed and CSI feedback is transmitted along with a flag.

Method for utilizing channel sparsity and coherence in CSI feedback

A two-dimensional constellation for data signals having improved bitwise mutual information of data points is based on a signal-to-noise ratio (SNR) and a code rate where, based on the SNR, data bits are mapped to pre-defined in-phase and quadrature values. The in-phase and quadrature values denote points in the two-dimensional space such that the efficiency of bitwise mutual information is adapted based on the SNR. The mapping is preferably subject to a constraint selected from one of quadrant symmetry Lagrangian (QSL), quadrant symmetry constraint (QSC), or rectangular structure constraint (RSC).

AI/ML empowered high order modulation

Timing adjustments or frequency offsets that at least partially compensate for Doppler shift (e.g., due to distance of a satellite transmitter or relative speed of a terrestrial receiver) of a signal, physical channel, or resource during wireless transmission are configured. The characteristics compensated comprise one of resource element (RE) mapping, channel state information reference signal (CSI-RS) configuration, bandwidth part (BWP) configuration, or control resource set (CORESET) configuration. Information indicating the multiple configurations is transmitted from a base station (BS) to at least one user equipment (UE). The timing adjustments or frequency offsets are specifically configured for one UE, a group of UEs, or the UEs served by a single serving cell. Joint transmission from multiple cells/TRPs/spotbeams may involve partial/full subcarrier alignment.
