Abstract

Disclosed by embodiments of the present application are a method and terminal device for transmitting data, the method comprising: a terminal device obtaining transmission control information of eachnetwork device among at least one network device, the transmission control information of each network device being used to indicate the state of a replication data transmission function configured bythe corresponding network device for a first data radio bearing (DRB), the state being an active state or an inactive state; the terminal device updating a control variable according to the transmission control information of each network device, the control variable being used to maintain the state of the replication data transmission function configured by a plurality of network devices for thefirst DRB, the plurality of network devices comprising the at least one network device; and the terminal device controls the replication data transmission function of the first DRB according to the updated control variable. The method and terminal device according to embodiments of the present application are conducive to improving the performance of data transmission.

Description

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