Abstract: Embodiments of this application provide an information transmission method and apparatus, to report different capabilities of different terminal device forms. According to the method provided in this application, a terminal device can independently report a first capability and/or a second capability. The first capability is related to a maximum radio frequency processing bandwidth, and the second capability is related to a maximum baseband processing bandwidth. This implements decoupled reporting of the maximum radio frequency processing bandwidth and/or the maximum baseband bandwidth. According to the solutions in this application, flexible reporting manners can be provided for terminal devices in different forms or different types to report capabilities, thereby meeting different commercial application and cost requirements.

Abstract: A route configuration method includes determining, by a session management network element, that a first terminal in a first group is allowed to communicate with a second terminal in a second group. The route configuration method further includes sending, by the session management network element, first forwarding information to a first user plane network element. The first user plane network element is configured to provide a service for the first terminal. The first forwarding information is useable by the first user plane network element to forward a first packet. The first packet is to be sent by the first terminal to the second terminal.

Abstract: A data transmission method and a device are disclosed. The data transmission method includes: a first communications device receives first information sent by a second communications device. The first information is used to indicate one or more of transport block set information, maximum transport block quantity information, transport block information, and first combination set information. The first communications device determines, based on the first information, a quantity of transport blocks scheduled by using control information, and a HARQ process number corresponding to each transport block in the transport blocks scheduled by using the control information. The first communications device sends data to the second communications device based on the determined quantity of transport blocks and the determined HARQ process number corresponding to each transport block, or receives, based on the determined quantity of transport blocks and the determined HARQ process number corresponding to each transport block, data.
