Abstract: A device-cloud collaboration method, platform, and apparatus, where the device-cloud collaboration method includes: obtaining current spatial information of each target terminal; tracking a spatial information change of each target terminal, to obtain a spatial information change status of each target terminal; and determining, based on spatial information-based arbitration conditions preset for different target mobile applications and the spatial information change status of the target terminal corresponding to the different target mobile applications, whether to trigger subsequent operations related to the different target mobile applications. The device-cloud platform blocks a change in which the user is not interested through arbitration of a spatial information change of the user, and provides an appropriate spatial information change to a mobile application, or triggers a subsequent operation of the mobile application.

Abstract: A computer-implemented method for data synchronization in a P2P ad hoc network includes retrieving network configuration information identifying a plurality of devices forming the P2P ad hoc network. A time offset between a local physical time at a first device and a local physical time of a second device is determined. A change in a data object of a plurality of data objects stored at a key-value store within the first device is detected, each of the data objects including a synchronization indicator. The data object change is communicated to at least the second device based on the synchronization indicator. Upon receiving confirmation from the at least the second device of receipt of the data object change, the network configuration information is updated with a timestamp based on the time offset and indicative of the local physical time at the first device when the data object change was communicated.

Abstract: Embodiments of this application disclose an uplink data transmission method and apparatus. Specifically, user equipment reports an uplink mode supported by the user equipment to a network device by using a capability message, where the uplink mode is an uplink mode for a first carrier and a second carrier of the user equipment. The network device determines, based on the capability message, the uplink mode supported by the user equipment, generates a configuration message, and sends the configuration message to the user equipment. The configuration message includes an uplink mode configured by the network device. After receiving the configuration message, the user equipment transmits uplink data in the uplink mode in the configuration message.

Abstract: A computer-implemented method for performing application data consistency management among a plurality of computing devices within a communication network includes retrieving by a first device, application data from a second device. The application data includes an app ID and a first application version number of an app residing on the second device. A first database table is updated using an object type associated with the app ID and the first application version number. The object type identifies a database table schema of a data object used by the app and a plurality of data fields of the data object. Data stored by one or more of the plurality of data fields is synchronized with a third device based on a second application version number of the app residing on the third device and the first database table.

Abstract: A communication method, apparatus, and system are provided, to decrease a degree of sensitivity degradation and reduce impact of the sensitivity degradation on network coverage performance. In the method, a network device sends first configuration information to a terminal device. When the first configuration information indicates that the terminal device is allowed to reduce a transmit power, the terminal device reduces the transmit power based on a power adjustment factor if a difference between reference sensitivity of a first power class and reference sensitivity of a second power class is greater than or equal to a first threshold in configured channel bandwidth. Before the transmit power is reduced, a power class of the terminal device is the first power class. The second power class is lower than the first power class.

Abstract: Example signal sending methods and apparatus are described. One example method includes obtaining a first insertion loss corresponding to a first resource and a second insertion loss corresponding to a second resource, where the first insertion loss is different from the second insertion loss. A first transmit power corresponding to the first resource is determined based on the first insertion loss. A second transmit power corresponding to the second resource is determined based on the second insertion loss. A first signal is sent on the first resource based on the first transmit power. A second signal is sent on the second resource based on the second transmit power.
