Non-scheduling resource based data sending method and apparatus thereof
A data sending method includes: receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to configure a non-scheduling resource; and starting, by the terminal device when a condition is met, a first timer, where the non-scheduling resource is not used for sending uplink data within duration of the first timer.
