Abstract: This application provides a phase correction method and a communication apparatus. In the phase correction method, a network device sends a combined signal to a terminal, where the combined signal is obtained by passing a first signal through N channels and combining output signals of the N channels. The terminal determines a precoding matrix based on the combined signal and feeds back the precoding matrix to the network device. The network device estimates a phase error between a plurality of channels of the network device based on the precoding matrix, and corrects phases of the N channels based on the obtained phase error. In the foregoing technical solution, soft correction of phases of N channels of the network device may be implemented by using an air interface feedback of a terminal, so that it can be ensured that the phases of the N channels are consistent.

Abstract: A system and method for conducting a tokenized electronic transaction may comprise: receiving identifying biometric data for the user, generating a biometric template representative thereof, and destroying the identifying biometric data. The identifying biometric data is not stored permanently, is not transmitted, cannot be derived from the biometric template, and is destroyed so that only the biometric template remains. The biometric template is attached to a transaction token for completing the transaction represented by the token including: comparing the token and attached biometric template with reference transaction data and with a reference biometric template. When the token matches the reference transaction data and the biometric template matches the reference biometric template, then the transaction is authorized and completed, and when the token and/or the biometric template does not match the reference therefor, then the transaction is rejected.

Abstract: A cross-platform game battle method and apparatus, a terminal, and a system are provided.
