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.

Abstract: Embodiments of this application provide a data sending method, a data receiving method, and a device. In the data sending method, a receive end device performs a DRX operation at a low frequency based on a DRX parameter; and receives, in a time indicated by the DRX parameter, first indication information sent by a transmit end device, where the first indication information is used to instruct the receive end device to prepare to receive data at a high frequency. In this process, the receive end device performs the DRX operation only at the low frequency, and starts beam tracking only after receiving the first indication information that instructs the receive end device to receive the data at the high frequency, to avoid unnecessary beam tracking and save power of the receive end device.

Abstract: The embodiments of the present disclosure disclose a small data transmission method and a related device and system. The method may include: broadcasting, by a base station, a paging message, where the paging message carries UE identifiers of a plurality of to-be-paged user equipment UE and small data sent to at least one of the to-be-paged UEs, and the small data is data whose data volume is less than a preset data volume threshold. In the present disclosure, small data may be sent to to-be-paged UE while the base station pages the UE, to reduce signaling and time overheads for sending the small data and improving communication efficiency.

Abstract: A time synchronization method, and device are described. The method includes determining a target base station from neighboring base stations of a source base station; determining, based on a preset handover condition and from first user equipments (UEs) connected to the source base station, a to-be-handed-over UE that needs to be handed over to the target base station; triggering the to-be-handed-over UE to be handed over from the source base station to the target base station; and performing time synchronization with the target base station in a handover process of the to-be-handed-over UE. The to-be-handed-over UE is triggered to be handed over to the pre-determined target base station. This implements time synchronization with the target base station, resolves relatively low flexibility of time synchronization between base stations in a related technology, and improves flexibility of time synchronization between the source base station and the target base station.

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.

According to the method, control information of the second network can be transmitted reliably.
