Abstract: Embodiments of this application provide a communication method and a communication apparatus. The method includes: A first communication apparatus receives a first indication parameter. There is a correspondence between the first indication parameter and first codeword-to-layer mapping. The first communication apparatus determines the first codeword-to-layer mapping based on the first indication parameter. Based on the method, in embodiments of this application, codeword-to-layer mapping can be dynamically adjusted and/or indicated. For example, a terminal device may use different codeword-to-layer mapping at different moments. For another example, different terminal devices may use different codeword-to-layer mapping at a same moment.

Abstract: Embodiments of the present invention relate to the communications field and disclose an access network node, a core network node, and a paging method, for use in a paging process, so as to resolve a problem that a machine to machine (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. In an embodiment, 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.

Abstract: Embodiments of this application provide a method for obtaining a target transmission route, a related device, and a system. The method is applied to a flexible Ethernet FlexE networking network and includes: receiving a first message that is sent by a second node for requesting to query for a transmission route of a first FlexE client; and sending a second message to the second node, where a route information entry in the second message includes route information of the FlexE client on each node. Ingress information and egress information that are of a FlexE client on a route node are recorded as a transmission route of each hop. A segment-to-segment transmission route in the FlexE network can be dynamically found in real time, a planned and deployed transmission route is compared with an actually found route, to evaluate a network running status.
