Abstract: A data management method, a system, and a device are provided. An example method includes: A data storage entity receives a data access request and sends an access permission verification request to a distributed ledger node storing a data access policy of the client and/or a data access policy of the user. The distributed ledger node verifies, based on an identifier of a client and/or an identifier of a user in the access permission verification request and a distributed ledger, whether the client has data access permission, and sends a first access permission verification response to the data storage entity if the client has the data access permission, where the first access permission verification response indicates that the client has the data access permission. After receiving the first access permission verification response sent from the distributed ledger node, the data storage entity sends corresponding data to the client.

Abstract: This application relates to the field of wireless communication, and in particular, to an orthogonal frequency division multiple access (OFDMA) hybrid transmission method and apparatus. The method includes: An access point may send a trigger frame, to schedule stations supporting different standards to perform OFDMA uplink transmission, where the stations supporting different standards support different bandwidth sizes. The stations receiving the trigger frame send a trigger-based physical layer protocol data unit (TB PPDU) to the access point, where the TB PPDU includes uplink data of the stations supporting different standards, and the stations of different standards may send the uplink data by using RUs located in bandwidths respectively supported by the stations. Therefore, a channel can be fully utilized to improve frequency domain resource utilization.
