Abstract: This application provides a communication method and a communications apparatus. The communication method includes: determining, by a transmit end device, a first moment, where the first moment is a moment when a receive end device needs to deliver first data to an upper layer of a communications protocol layer of the receive end device; and sending, by the transmit end device, first indication information and the first data, where the first information is used to instruct the receive end device to deliver the first data to the upper layer of the communications protocol layer of the receive end device at the first moment. The receive end device can be supported in determining the first moment based on the first indication information and delivering the first data to the upper layer of the communications protocol layer at the first moment.

Abstract: This application provides a communication method and a communications device. The method includes: obtaining, by a first communications device, authorization information, where the authorization information indicates that a second communications device is a device that needs to perform time synchronization; and providing, by the first communications device, time information for the second communications device based on the authorization information; or obtaining, by the first communications device, authorization information, where the authorization information indicates that the second communications device is not a device that needs to perform time synchronization; and skipping, by the first communications device, providing time information for the second communications device based on the authorization information, to avoid broadcasting the time information to all communications devices, so that a time synchronization service can be provided for a specific communications device.

Abstract: Embodiments of the present disclosure provide a method for receiving D2D discovery information and an apparatus. The method for receiving D2D discovery information includes: sending, by an upper layer of a radio resource control RRC layer of a D2D communication device, a first instruction to a physical layer of the D2D communication device, where the first instruction is used to instruct the physical layer to switch from a D2D sleep state to a D2D listening state; and receiving, by the physical layer of the D2D communication device, the first instruction and switching from the D2D sleep state to the D2D listening state according to the first instruction, to listen to D2D discovery information. This reduces power consumption of the D2D communication device and prolongs a standby time of the D2D communication device.

Abstract: The present invention provides a data sending method. The method includes: allocating, by a Media Access Control MAC entity of a first network node, data packets to at least one hybrid automatic repeat request HARQ unit of at least two cells, where the at least two cells use different radio access technologies RATs, the at least two cells share one HARQ unit or each of the at least two cells is corresponding to one HARQ unit, and the HARQ unit is a HARQ entity and/or a HARQ process; and sending, by the first network node, the data packets to a second network node by using the at least two cells. According to the foregoing solution, the data packets are allocated to the at least one HARQ unit of the at least two cells by using a shared MAC layer, so as to effectively reduce an end-to-end delay.

Abstract: The present invention discloses a method for reporting a measurement report of a measurement event, including: determining that a measurement event is generated in a user equipment UE in an activated state of discontinuous reception DRX mode; judging whether a first time to trigger corresponding to the measurement event is valid when it is determined that there is a measurement event generated; using, when it is judged that the first time to trigger is valid, the first time to trigger to time the measurement event; using, when it is judged that the first time to trigger is invalid, a second time to trigger to time the measurement event, such that the UE is in next one or next several activated states of DRX mode after the generation of the measurement event. The present invention can improve a success rate of mobility handover between cells or wireless link quality.
