Abstract

The embodiment of the invention relates to a data transmission method and a user terminal, and the method includes the steps: determining logic channel deactivation; canceling an uplink SR (schedulingrequest) correspondingly triggered by a BSR (buffer status report) triggered by a logic channel, or canceling an RACH (random access channel) correspondingly triggered by the BSR triggered by the logic channel according to a command, or canceling the LCP (logic channel priority) restriction corresponding to the logic channel according to the command. In this way, after determining logic channel deactivation, UE can cancel the SR triggered by the BSR triggered by the logic channel, or cancel the RACH triggered by the BSR triggered by the logic channel, thereby reducing unnecessary data transmission and avoiding resource waste; or, cancel the LCP restriction corresponding to the logic channel to ensure reasonable data transmission and reduce unnecessary data transmission restrictions.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a data transmission method and a user terminal. Background technique [0002] At present, in the Long Term Evolution (LTE for short) system, a DC (Dual Connectivity) dual connectivity function is introduced, and the protocol stack of the dual connectivity function is as follows: figure 1 As shown, among them, MeNB (macro base station) and SeNB (secondary base station) are the primary and secondary base stations respectively, and some bearers of UE (User Equipment, user terminal) can be transmitted in MeNB and SeNB respectively. In the figure, MCG Bearer is the primary cell group Bearer, the SplitBearer is the fork bearer, and the SCG Bearer is the secondary cell group bearer. [0003] In the discussion of 5G (fifth generation mobile communication technology) NR (new Radio, new radio), due to the demand for high reliability services, 3GPP (...
