摘要
A user equipment (UE) may reduce a peak to average power ratio (PAPR) ratio for an uplink transmission. The UE may receive an indication of an allowed error vector magnitude (EVM) for each of an uplink data signal, an uplink reference signal, and an uplink control signal from a base station. The base station may determine the allowed EVM based on a signal to noise ratio (SNR) for the UE measured at the base station. The UE may generate one or more uplink signals. The UE may apply a PAPR reduction to the one or more uplink signals based on the allowed EVM corresponding to each of the one or more uplink signals. The UE may transmit the one or more uplink signals to the base station.
