A user equipment (UE) may multiplex a peak suppression information message (PSIM) with data on a physical uplink shared channel (PUSCH) to efficiently implement PSIM for peak-to-average power ratio (PAPR) reduction. The UE may clip a peak from a signal to be transmitted and capture information of the clipped peak into the PSIM. The UE may then multiplex the PSIM on the PUSCH such that a receiving device (e.g., a base station) may receive the signal and reconstruct the signal (e.g., PUSCH data) using the PSIM. According to some aspects, each PUSCH symbol may include a PSIM for a previous PUSCH symbol (e.g., such that causality is preserved in the case of multiplexing the PSIM and data for each PUSCH symbol). Various aspects of the techniques described herein may further provide for PSIM positioning in frequency, PSIM modulation, PSIM channel coding, PSIM multiple input multiple output (MIMO) configuration, and the like. 用户装备(UE)可在物理上行链路共享信道(PUSCH)上复用峰值抑制信息消息(PSIM)与数据以高效地实现PSIM以用于峰均功率比(PAPR)降低。UE可从要被传送的信号削波峰值，并
