Abstract: A communication method for a dual connectivity system and a communication apparatus are disclosed, to support relaxing radio resource management (RRM) measurement. The method includes: A first network device determines that a terminal device is to deactivate a secondary cell group (SCG) of the terminal device; the first network device sends first information to the terminal device, where the first information indicates the terminal device to deactivate the secondary cell group SCG of the terminal device, to enable the terminal device to relax SCG RRM measurement after deactivating the SCG; and the terminal device relaxes the SCG RRM measurement after deactivating the SCG based on the first information. The first network device is a master node or a secondary station of the terminal device. In this way, when the SCG is deactivated, relaxing the

Abstract: A terminal device generates a report result including at least one of a logged minimization of drive tests report, an RLF report, and an RACH report. The logged minimization of drive tests report includes an identifier of a candidate access cell, information indicating whether the candidate access cell supports a network slice service initiated by the terminal device, location information of the terminal device where the terminal device receives a system message of the candidate access cell, and a network slice identifier of the network slice service initiated by the terminal device. The RLF report includes an identifier of a cell in which a radio link failure occurs after the terminal device accesses the cell and the network slice identifier corresponding to the network slice service in which the radio link failure occurs on the terminal device. The RACH report includes an identifier of a cell accessed by the terminal device and the network slice identifier. The terminal device sends the report result to a radio access network device to which a serving cell belongs.

Abstract: Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.
