    Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

    Abstract: Embodiments of the present invention disclose an access network node, a core network node, and a paging method, and relate to the communications field, so as to resolve a problem that an M2M service cannot be normally used because a network side cannot determine whether a coverage enhancement technology needs to be used in a paging process. A specific solution is as follows: A communications interface is configured to receive a first packet paging message sent by a core network node; a processor determines, according to the first packet paging message received by using the communications interface, that a terminal is an M2M terminal; and a transmitter sends a coverage-enhanced second packet paging message to the terminal. The present invention is used in a paging process.

    Abstract: Data contention caused by multiple threads accessing one data block at the same time when used to execute tasks concurrently may be avoided, and difficulty in detecting and debugging a concurrent error may be reduced. A solution is: adding, according to correspondences between multiple tasks and M data blocks that are accessed by the multiple tasks, each of the multiple tasks to a task queue of a data block corresponding to the task; using N threads to execute tasks in N task queues of M task queues concurrently, where each of the N threads executes a task in a task queue of the N task queues, different threads of the N threads execute tasks in different task queues, and 2≤N≤M.

    Abstract: Embodiments of the present disclosure disclose a modulator, including: a first modulation module, configured to: receive first to-be-modulated data, and output a first transmission curve according to the first to-be-modulated data; a second modulation module, configured to: receive second to-be-modulated data, and output a second transmission curve according to the second to-be-modulated data, where a period of the second transmission curve is half of a period of the first transmission curve; and a combination module, configured to perform phase superposition on the first transmission curve and the second transmission curve, to obtain a combined linear result. In addition, this solution further provides a modulation system and a method for implementing higher order modulation, so that a linear result that can be modulated can be obtained by controlling a superposition ratio between transmission curves, to implement linear curve transmission.
