    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: Embodiments of the present disclosure relate to a grant-free uplink transmission method and apparatus. The method includes: determining, based on received configuration information, a target grant-free transmission area and a target air interface transmission parameter corresponding to the target grant-free transmission area, where the target grant-free transmission area is an air interface time-frequency resource formed by using a specified time range and frequency range, and the configuration information includes at least one grant-free transmission area and an air interface transmission parameter corresponding to each grant-free transmission area; and sending uplink data to a base station based on the target grant-free transmission area and the target air interface transmission parameter. In this application, it can be provided that the base station can correctly receive the uplink data.

    Abstract: This application relates to the wireless communications field, and discloses a random access method and apparatus, to resolve a problem of how a terminal device selects an uplink to perform random access. The method includes: selecting, by a terminal device, a first uplink from at least two preconfigured uplinks to perform random access; and selecting, by the terminal device when random access performed by using the first uplink fails, a second uplink from the at least two uplinks to perform random access, where the at least two uplinks are communications links between the terminal device and a first network device, the first network device and the terminal device are located in a same cell, the first uplink is a normal uplink NUL, and the second uplink is a supplementary uplink SUL. In this way, the terminal device selects an uplink to perform random access.
