摘要： 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. In this application, the uplink mode supported by the user equipment is predefined and reported to the network device, and then the network device can configure an available uplink mode for the user equipment, so that the user equipment can transmit data in different uplink modes, thereby increasing uplink data transmission efficiency.

摘要： Embodiments of this application relate to the communication field, and provide a communication method, a device, and a system, so that two SIM cards of a terminal device can use capabilities of the terminal device in a sharing manner. A key inventive point of this application is as follows: A terminal device reports, to a first access network device corresponding to one SIM card, that the terminal device supports two user identities in sharing capabilities of the terminal device, and also reports a capability of the terminal device that is occupied by a second access network device corresponding to the other SIM card, so that the first access network device can configure a serving cell for the terminal device based on the capability of the terminal device that is occupied by the second access network device. Therefore, the capabilities of the terminal device can be shared between the two user identities, and the capabilities of the terminal device are fully utilized. This avoids a limitation, in a current technology, of a rigid capability division manner on a capability of the terminal device that can be used by each SIM card, and can improve a data transmission speed of the terminal device.

摘要： This application provides a dual connectivity configuration-based communication method, an apparatus, a device, and a storage medium. The method includes: A terminal device may receive a deactivation command sent by a master node or a secondary node. The terminal device deactivates an SCG or a PSCell according to the deactivation command. To be specific, the terminal device may deactivate the SCG or the PSCell based on an actual situation. For example, when the terminal device has a low requirement for a data transmission rate, the terminal device receives the deactivation command, and deactivates the SCG or the PSCell according to the deactivation command. After the SCG or the PSCell is deactivated, based on this, the terminal device does not need to listen on PDCCHs of the PSCell and an SCell in the SCG, and does not need to send an uplink signal such as an SRS or CSI on the PSCell and the SCell in the SCG. Therefore, power consumption of the terminal device can be reduced.
