Abstract: Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

Abstract: A method for transmitting system information is disclosed. A first terminal device obtains first indication information. The first terminal device, based on the first indication information, determines system information (SI) required by a second terminal device. The second terminal device communicates with a base station via the first terminal device. The first terminal device sends a message comprising target SI to the second terminal device. The target SI is some or all of the SI required by the second terminal device.

Abstract: User equipment, a base station, a base station access method, and a radio link monitoring method are provided, where the user equipment includes: a first receiving module, configured to receive first indication information sent by a first base station, where the first indication information includes a time period required by the user equipment to initially request to access a second base station; a first sending module, configured to send the random access scrambling code to the second base station; and a first notification module, configured to: if the user equipment fails to access the second base station within the time period, notify the first base station that a secondary cell group failure occurs. In this application, efficiency of accessing the second base station by the user equipment is improved by limiting a time in which the user equipment requests to access the second base station.

Abstract: User equipment provides, to a network device, reference paging information generated according to a moving speed of the user equipment. The reference paging information is used by the network device to determine a paging area for sending a paging message. The network device receives the reference paging information generated by the user equipment according to the moving speed of the user equipment. The network device determines, according to the reference paging information, a paging area for sending a paging message to the user equipment. The network device sends, in the paging area, the paging message to the user equipment. The network device can determine the paging area according to the reference paging information, so that a paging resource waste in a paging process is reduced, relatively accurate paging is implemented, overheads of inter-network interfaces and air interfaces are greatly reduced, and system efficiency and stability are improved.

Abstract: A data sending method is provided. 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.
