Abstract: A data transmission method includes receiving, by a centralized unit (CU), a first message from a distributed unit (DU). The first message includes a first transport block size (TBS) threshold. The first TBS threshold is useable for early transmission of uplink data. The method further includes sending, by the CU, the first TBS threshold to a UE, and receiving, by the CU, uplink data from the UE based on the first TBS threshold.

Abstract: Embodiments of this application provide a cell obtaining method and a terminal to reduce power consumption of the terminal. Technical solutions provided in the embodiments of this application are as follows: When a terminal is connected to a current source serving cell, the terminal obtains a first quality parameter of the current source serving cell; if the first quality parameter is less than a first preset threshold, the terminal determines a measurement cell set; the terminal measures each measurement cell in the measurement cell set to obtain each corresponding second quality parameter; and the terminal determines a target serving cell based on the second quality parameter.

Abstract: The present disclosure provides a method and an apparatus for determining a transmission solution. The method includes: obtaining, by a base station, a transmission solution switching instruction of UE, where the transmission solution switching instruction of the UE is used to instruct to switch a transmission solution of the UE from user plane transmission to control plane transmission or from control plane transmission to user plane transmission, and configuring, by the base station, a switched-to transmission solution with the UE based on the transmission solution switching instruction. The base station obtains the transmission solution switching instruction by using statuses of the UE or a core network device, and configures the switched-to transmission solution with the UE, so that switching of the transmission solution of the UE is implemented, without a need of performing re-attach to the core network device and tracking area update by the UE.

Abstract: A system information sending method is provided, to resolve a technical problem that UE may not receive a paging message when a DRX cycle is greater than an MP. A network device may separately set a modification period (namely, a first period) for first-type system information (which, for example, may include paging configuration information), to ensure that the first-type system information is not to be modified in the first period. For example, the first period may be greater than a DRX cycle. In this way, when a terminal device wakes up based on the DRX cycle, a time when the terminal device wakes up is still in the first period. The terminal device may normally receive a paging message indicating that the paging configuration information is to be modified, thereby obtaining new paging configuration information in time and avoiding missing a subsequent paging message.
