Abstract: Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving broadcast information by a terminal device. The broadcast information includes a first parameter and a second parameter that are for a first cell. The first parameter is used for cell selection or cell reselection performed by a terminal device that supports supplementary uplink (SUL) carrier transmission, and the second parameter is used for cell selection or cell reselection performed by a terminal device that does not support SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the first parameter when the terminal device supports SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the second parameter when the terminal device does not support SUL carrier transmission.

Abstract: This application provides a failure processing method, a handover method, a terminal device, and a network device, to provide a manner in which a terminal receives an RRC configuration of a secondary network device and feeds back an RRC configuration failure. The method includes: directly receiving, by a terminal device, a first RRC configuration of a secondary network device from the secondary network device; and when the first RRC configuration fails, sending, by the terminal device, first indication information to a primary network device to indicate that the first RRC configuration fails. In addition, when the first RRC configuration fails, the terminal reports one piece of first indication information to the primary network device to indicate that the first RRC configuration fails.

Abstract: Embodiments of the present disclosure provide a method for accessing an inter-RAT cell and a related device, and the method includes: sending, by a base station, a first message to a terminal, where the first message is used to instruct the terminal to access an inter-RAT cell, and an LTE cell and the inter-RAT cell are different cells. Beneficial effects are as follows: The first message is sent to the terminal, so that the terminal directly accesses the inter-RAT cell without a need to access the base station. In this way, the terminal does not need to perform a handover procedure, thereby reducing a delay in an access process, effectively ensuring that the terminal can successfully access the inter-RAT cell, and effectively ensuring that a radio access technology new RAT service can be performed between the terminal and a base station of the inter-RAT cell.

Abstract: This application provide example mobility management methods, access network control devices, and communications systems. One example method includes receiving, by an access network control device, a location area request message of user equipment (UE) through a first station, where the UE is located in a cell managed by the first station. The access network control device can configure at least one location area identity list for the UE based on the location area request message, where the location area identity list includes at least one location area identity, and the location area identity is used to identify a location area. The access network control device can then send the at least one location area identity list to the UE through the first station.

Abstract: The present disclosure discloses a data transmission method, device, and system, and belongs to the field of communications technologies. The method includes: receiving a data packet sent by user equipment, where the data packet carries indication information used to instruct a base station to establish a specified data connection to the user equipment; generating a first key of the user equipment based on the indication information and a public key of the base station; and performing data transmission with the user equipment based on the first key of the user equipment. According to the data transmission method, the transmitted data can be encrypted and decrypted when there is no radio resource control connection between the base station and the user equipment, thereby improving data transmission security while ensuring data transmission efficiency.

Abstract: This application provides a clock synchronization method and a communication apparatus, and relates to the field of communication technologies, to implement clock synchronization between a terminal device and a network device. The method includes: A first terminal device receives first time information. The first time information indicates time of a lower boundary of a reference system frame SF on a network-side clock, and the reference SF is transmitted through a Uu interface. The first terminal device receives first reference information. The first reference information indicates a first reference direct frame DF, and the first reference DF is transmitted through a PC5 interface. Then, the first terminal device implements clock synchronization with a network device based on the first time information and the first reference information. The first reference DF corresponds to the reference SF. The first terminal device is a remote terminal device in a user equipment-to-network U2N scenario.
