摘要
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.

This application is a continuation of International Application No. PCT/CN2018/109494, filed on Oct. 9, 2018, which claims priority to Chinese Patent Application No. 201710950499.6, filed on Oct. 13, 2017. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties.
This application relates to the communications field, and more specifically, to a communication method and a communications apparatus.
Currently, a control technology that a receive end device receives an operation instruction (in other words, control information) sent by a transmit end device, and after receiving the control information, immediately performs an action instructed by the operation instruction is known. In the technology, to ensure accurate control on the action performed by the receive end, the transmit end device needs to learn of a transmission latency of the control information between the transmit end device and the receive end device, to take the transmission latency into consideration when designing the operation instruction, so that the receive end device can perform the action instructed by the operation instruction at an expected time.
When the transmit end device and the receive end device communicate in a wired manner, the transmission latency is fixed, and therefore, the transmit end device can accurately speculate, based on the fixed transmission latency, the time of performing the action by the receive end device.

What is claimed is:1. A communication method, comprising:determining, by a transmit end device, a first moment, wherein 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 to the receive end device, wherein the first indication 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, wherein the sending, by the transmit end device, first indication information and the first data comprises determining, by the transmit end device, second duration, wherein the second duration is duration between a current moment and the first moment; and sending, by the transmit end device when determining that the second duration is greater than or equal to a preset first threshold, the first indication information and the first data. 2. The communication method according to claim 1 , wherein the first indication information comprises indication information of the first moment. 3. The communication method according to claim 1 , wherein the first indication information comprises indication information of a first duration, wherein:the first moment is a moment that a preset second moment reaches after the first duration. 4. The communication method according to claim 3 , wherein the second moment is a moment when the transmit end device receives the first data, or a moment when the transmit end device sends the first data. 5. A communication method, comprising:receiving, by a receive end device, first indication information and first data, wherein the first indication information is used to instruct the receive end device to deliver the first data to an upper layer of a communications protocol layer of the receive end device at a first moment; and sending, by the receive end device, the first data to the upper layer of the communications protocol layer of the receive end device at the first moment, if a current moment is before the first moment or the current moment is the first moment; and discarding, by the receive end device, the first data, if the current moment is after the first moment. 6. The communication method according to claim 5 , wherein the first indication information comprises indication information of the first moment. 7.
