Example communication methods and apparatus are described. One example method includes determining by a terminal that a first transmission resource conflicts with a second transmission resource. The first transmission resource is a resource used by the terminal to send first information to a first network side device. The first network side device corresponds to a first user identity supported by the terminal. The second transmission resource is a resource used by the terminal to send second information to a second network side device. The second network side device corresponds to a second user identity supported by the terminal. The terminal sends the first information on the first transmission resource. The terminal cancels sending the second information on the second transmission resource. Alternatively, the terminal sends the second information on a third transmission resource, where the third transmission resource is a resource before or after the second transmission resource.

Communication method and apparatus

This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: After registering with a first network and a second network, a terminal device may send first information to a network device in the first network or a network device in the second network, so that the network device in the first network or the network device in the second network can learn that the terminal device is to enter a first transmission manner or has entered the first transmission manner. The first transmission manner includes: The terminal device concurrently processes an uplink service of the first network and an uplink service of the second network.

A communication method includes establishing, by a communication device, a first connection to a first network device and a second connection to a second network device. The first connection and the second connection are used to process a first service. The method also includes sending, by the communication device, first information to the first network device based on the communication device determining that a second service needs to be processed. The second service is different from the first service. The first information is used to request to disable the first connection or the second connection, or the first information is used to indicate the communication device to establish a third connection to a third network device. The third connection is used to process the second service.

A dual connectivity management method and device, the method including sending by a terminal device that communicates with a first network device and a second network device in a dual connectivity mode, a first message to the first network device, where the first message indicates or requests deactivation or suspension of the dual connectivity, and deactivating or suspending the dual connectivity.

Dual connectivity management method and communications apparatus

A first modem performs a first communication service in a first frequency band. A second modem performs a second communication service in a second frequency band. The first modem and the second modem are in a first operating mode. The first modem receives, from an access network device, a switching instruction for the first communication service, where the switching instruction is used to instruct the first modem to switch from the first frequency band to a third frequency band. The first modem indicates to an arbitration apparatus that the first modem needs to be switched to the third frequency band. The arbitration apparatus determines whether the third frequency band conflicts with the second frequency band, to perform: maintaining the first operating mode, or switching the first operating mode to a second operating mode for the first modem and the second modem.

Method for performing communication service by using plurality of modems

This application provides a signal receiving method and a terminal device, to improve user experience. The method is applied to a terminal device provided with a plurality of subscriber identification module SIM cards, the terminal device is provided with a plurality of receive antennas, and the method includes: switching from a first mode to a second mode when a channel environment of a first SIM card meets a preset condition, where the first SIM card is a SIM card configured to receive a high-priority signal, the high-priority signal includes a paging message, a system message, or downlink signaling in a signaling interaction procedure, and a quantity of receive antennas configured for the first SIM card in the first mode is different from a quantity of receive antennas configured for the first SIM card in the second mode.

Signal receiving method and terminal device

A wireless communications apparatus and a wireless communication method are provided. The method includes: deactivating a first wireless communication capability of a first communications module, so that the first communications module does not support the first wireless communication capability; activating a first wireless communication capability of a second communications module, so that the second communications module supports the first wireless communication capability; sending a first uplink message, where the first uplink message is used to indicate that a first user identity does not support the first wireless communication capability; and sending a second uplink message, where the second uplink message is used to indicate that a second user identity supports the first wireless communication capability. In embodiments of this application, the wireless communications apparatus can provide a better service during communication by using the second user identity, without changing a correspondence between the user identity and the communications module.
