The present disclosure describes methods and apparatuses for phase-based cyclic redundancy check (CRC) verification for wireless communication. In some aspects, a soft phase value and a sliced phase value are received for a symbol of a data packet, the data packet received via a wireless interface. An error measurement is determined for the symbol based on the soft phase value and the sliced phase value. The error measurement for the symbol is then compared to an error measurement threshold for detecting symbol-level errors in the data packet. Based on the error measurement exceeding an error measurement threshold, a bit error can be detected in the data packet, which may have passed CRC. By detecting the bit error despite a CRC pass, the bit error can be indicated to higher-level entity of the wireless interface. This can be effective to prevent the bit error from impairing operation of the higher-level entity.
