Abstract: A communication method includes receiving, by a terminal device comprising a processor, indication information from a master node. The indication information is used to indicate that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second signaling radio bearer (SRB) is a first key. The first key is used for signaling transmission performed between the terminal device and the master node by using a first SRB. The first secondary node and the master node share one central unit. The communication method also includes determining, by the terminal device, based on the indication information, that the first key is used for signaling transmission performed between the terminal device and the first secondary node by using the second SRB.

Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: This application provides a communication method and apparatus, to determine a DRX cycle. The method includes: receiving data in an active time of a current DRX cycle; when a DRX inactivity timer of the current DRX cycle expires, determining a type of a next DRX cycle depending on whether at least some data received in the active time is associated with a DRX short cycle, where if the at least some data is not associated with a DRX short cycle, the next DRX cycle is a DRX long cycle, or the type of the next DRX cycle is the same as that of a DRX cycle previous to the current DRX cycle. When the DRX inactivity timer expires, the type of the next DRX cycle can be more flexibly determined, and may not necessarily be a DRX short cycle. This can save power of a device to some extent.

Abstract: This application provides a measurement configuration method and an apparatus. The method includes: determining that a serving cell changes from a first cell to a second cell; and updating or deleting a current measurement window configuration. The measurement window configuration is used to indicate a time domain position at which a terminal device measures a downlink reference signal. According to the solution provided in this application, when the serving cell of the terminal device changes, the current measurement window configuration of the terminal device is updated or deleted, so that a problem that the measurement window configuration of the terminal device is not applicable to measurement can be resolved to some extent.
