Abstract: The present disclosure relates to wireless communication methods and apparatus. One example method is executed in a communications system including N cells, where at least two cells of the N cells perform wireless communication by using a same carrier set, the carrier set includes M carriers, the M carriers are divided into N time-frequency resource groups, the M time-frequency resources in a same time-frequency resource group are in a one-to-one correspondence with the M carriers, and time domain locations of time-frequency resources corresponding to a same carrier are different, N≥2, and M≥2. The example method includes determining, by a network device, a first time-frequency resource group from the N time-frequency resource groups, and performing, by the network device, wireless communication in a first cell of the N cells by using one or more time-frequency resources in the first time-frequency resource group.

Abstract: Embodiments of this application disclose a data storage method. The method includes: A data storage service system including two nodes is deployed on a wheeled mobile device (for example, an intelligent vehicle, an autonomous vehicle, or a connected vehicle). A first node is a primary node, and a second node is a secondary node. A first process and a second process respectively run on the first node and the second node. When the first node receives a data write request, the first node first invokes a first database engine by using the first process to write data to a first storage module on the first node, and then in a blocking mode, the first node enables the second node to invoke a second database engine by using the second process to perform a same data write operation on a second storage module on the second node.
