Description

TECHNICAL FIELD Embodiments of the present disclosure relate to the technical field of communication, and more particularly, to a data transmission method, a terminal device, and a computer-readable storage medium. BACKGROUND The Narrow Band Internet of Things (NB-IOT) is a new narrow band Internet of Things with low power consumption, wide coverage and massive supported connections. Compared with the conventional mobile networks, the Physical Uplink Control Channels (PUCCHs) are cancelled in the NB-IOT system. Consequently, when a terminal device state or downlink channel quality of a terminal device is changed after the terminal device accesses the eNodeB (base station), the terminal device cannot notify relevant information to the base station timely, so that the base station cannot better optimize scheduling. WO 2019/151819 A1 relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). INTEL CORPORATION: "Quality report in Msg3 and connected mode for eMTC", XP051708807, relates to the designs for the support of DL quality report in Msg3 in Idle mode. US 2020/007274 A1 relates to systems and methods for generating and decoding messages including header extensions. It can be determined that a header extension is required for signaling a LCID value. A MAC sub-header including an indicator that the LCID value is extended can be generated and transmitted. A received message including a header extension can be decoded appropriately.
