Abstract: This application provides a data transmission method and a terminal device, to reduce a data transmission latency and improve data transmission reliability. The method includes: obtaining, by a terminal device, a grant-free GF resource configured by a base station; obtaining, by the terminal device, current channel quality; and if the current channel quality is first channel quality, transmitting, by the terminal device, to-be-transmitted data by using the GF resource, or transmitting, by the terminal device, the to-be-transmitted data by using a GB resource, where the first channel quality falls within a first range; or if the current channel quality is second channel quality, skipping, by the terminal device, transmitting to-be-transmitted data by using the GF resource, where the second channel quality falls within a second range; where the first channel quality is better than the second channel quality, and the first range is different from the second range.

Abstract: A PRACH resource selection method includes a terminal device receiving N synchronization signal blocks (SSBs) from an access device, determining a target PRACH resource selection manner based on at least one of a service type, a type of a trigger event that triggers random access, a signal strength change status of a reference signal received by the terminal device, mobility of the terminal device, and historical information, and selecting, in the determined selection manner, a target PRACH resource from N PRACH resources corresponding to the N SSBs.
