Abstract: Embodiments of this application provide a data transmission method and apparatus. The method includes: receiving data sent by a terminal in an inactive state, where the data includes to-be-sent data sent by the terminal and identification information of the terminal; determining an anchor base station of the terminal based on the identification information; and sending the data to the anchor base station, so that the anchor base station sends the data to a core-network device. The uplink data of the terminal is forwarded to the anchor base station by using a serving base station and through an interaction between the anchor base station and the serving base station that currently provides an air interface resource for the terminal, and is then transmitted to a core network.

Abstract: The present disclosure provides a method and device for monitoring a licensed-assisted access cell. The method includes user equipment receiving notification signaling from a base station, where the notification signaling is used to instruct the user equipment to monitor a target LAA cell. The user equipment monitors for a specified signal of the target LAA cell after receiving the notification signaling. In this way, user equipment does not need to continually monitor or receive a signal of an LAA cell and power consumption can be reduced.

Abstract: Embodiments provide a method for controlling an uplink transmit power in inter-base station carrier aggregation. The method includes acquiring, by a first base station, a maximum uplink transmit power that is allocated by user equipment (UE) to the first base station, and configuring, by the first base station, an uplink transmit power for the UE according to the maximum uplink transmit power. In the method, because the maximum transmit power allocated to the first base station is allocated according to status information of an uplink resource of a second base station, a power that is allocated by the UE to each base station can be coordinated.
