Abstract: 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.
