Abstract

Disclosed in the embodiments of the present application are a data transmission method, a terminal device and a network device. The method comprises: a terminal device acquiring first transmission control information of each network device among a plurality of network devices, the first transmission control information of a first network device among the plurality of network devices being used toindicate that the state of the replicated data transmission function configured for a first data radio bearer (DRB) by the first network device is activated, the first transmission control informationof a second network device among the plurality of network devices other than the first network device being used to indicate that the state of the replicated data transmission function configured forthe first DRB by the second network device is de-activated; and the terminal device determining, according to the first transmission control information of each network device, that a target networkdevice for controlling the replicated data transmission function of the first DRB is the first network device. The method, terminal device and network device of the embodiments of the present application help to improve data transmission performance.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, relate to a method for transmitting data, a terminal device, and a network device. Background technique [0002] In the existing discussion of New Radio (NR), for a bearer configured with a data copy transmission function, the data copy transmission function of a certain bearer can be dynamically activated (activated) or de-activated (de-activated). For the case of multiple connections, multiple network devices may respectively instruct the terminal device to activate or deactivate the function of copying data carried by a certain terminal. This may lead to different statuses of the copy data function indicated by different network devices for the same bearer. Therefore, there is an urgent need for a method to control the copy data transmission function of a certain bearer in the above scenario. Contents of the invention [0003] In view of this, the...
