Abstract: A transmission method is implemented by a communications device including a first functional entity and a second functional entity. A first carrier is configured for the first functional entity, and a second carrier is configured for the second functional entity. The second functional entity obtains first information, where the first information is first control information of the first functional entity, or is the first control information and second control information of the second functional entity, the first control information includes a first identifier, and the first identifier is used to indicate the first carrier; and the second functional entity sends the first information by using the second carrier.

Abstract: Embodiments of the present invention relate to communications technologies, and provide a data transmission method and an apparatus. The method includes: sending, by a base station, a grouping instruction to a target terminal, where the grouping instruction is used to group, in a preset grouping manner, terminals in a cell in which the target terminal is located into N groups, totally or partially different resources are allocated to terminals in different groups of the N groups, and a resource corresponding to an ith group of the N groups is used by a terminal in the ith group in uplink non-scheduled transmission; and receiving data that is sent by the target terminal using a target resource. In the solutions, terminals in a cell are grouped, and terminals in a same group contend for a resource allocated to the group. This mitigates resource collision when an uplink non-scheduled transmission solution is used.

Abstract: Embodiments of this patent application provide a data transmission method and an apparatus for determining, by a core network (CN) device, a length of a quality of service flow identifier (QFI) used when a protocol data unit (PDU) session is established or modified for a terminal device; and sending, by the CN device, a first message to a radio access network (RAN) device, where the first message includes length information of at least one QFI. After receiving the first message from the core network CN device, the access network RAN sends a second message to the terminal device, where the second message includes the length information of the at least one QFI.

Abstract: The present disclosure provides an uplink data packet transmission method. The method includes: determining, by a terminal device, a CP length of a first uplink data frame; if the terminal device is in a state of out of uplink synchronization with a base station and in an RRC connected state, or is in an RRC idle state, generating the first uplink data frame for an uplink data packet according to the CP length and sending the first uplink data frame to the base station. The CP length is greater than a CP length of an uplink data frame sent by a terminal device that is in a state of uplink synchronization and in an RRC connected state. Therefore, signaling procedures such as random access and uplink synchronization can be omitted, so that the terminal device can directly send the uplink data packet by performing signaling exchange once.
