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.
