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: The embodiments provide a resource allocation method and a communications apparatus. The method includes: a first node sends, to a radio access network device, first indication information used to indicate that the first node is a node responsible for terminal device management. The radio access network device allocates a first resource to the first node based on terminal devices that the first node is responsible for managing, and sends first resource information to indicate the first resource. In other words, the first node sends, to the radio access network device, the first indication information used to indicate that the first node is the node responsible for terminal device management, so that the radio access network device allocates different first resources based on different terminal devices that the first node is responsible for managing.

Abstract: A reference time determining method and apparatus are provided, to prevent aberrations in a control instruction execution time caused by inconsistency between a reference time of a terminal and a reference time of a control device in the conventional technology. In this application, the terminal may receive a plurality of pieces of time reference information sent by the network device. When the terminal receives indication information from the network device, the terminal may select, based on the indication information, one piece of time reference information from the plurality of pieces of time reference information as first time reference information. The indication information indicates the first time reference information. After determining the first time reference information, the terminal may determine the reference time of the terminal based on the first time reference information.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

Abstract: Embodiments of the present invention provide a base station, a terminal device, and a communication system for inter-base station carrier aggregation. A primary base station of the terminal sends a message including indication information to request the terminal device to report a timing offset between the primary base station and a secondary base station of the UE. The secondary base station calculates a corrected measurement gap information according to a measurement gap information and the timing offset. In a second measurement gap period indicated by the corrected measurement gap information, the terminal device is not scheduled.
