    Abstract: This application provides a method for sending uplink information in a wireless communication system that supports various services such as ultra-reliable and low latency communications (URLLC). A terminal device receives a timing advance coefficient from a network device. The terminal device determines value of a first timing advance based on a first time length and the timing advance coefficient. The first time length is one of at least two different time lengths that are supported by the terminal device. The terminal device sends the uplink information to the network device based on the first timing advance. With this method, the terminal device can uses different timing advances in different scenarios, so that diversified requirements of the fifth generation (5G) mobile communication systems for uplink synchronization are satisfied.

    Abstract: A data transmission method and a communications device resolve an existing problem that use of an unlicensed spectrum is interfered with between LTE devices when a padding is sent. The method includes: performing, by a communications device, CCA on an unlicensed spectrum; and when determining that the unlicensed spectrum is in an idle state, sending, by the communications device on a preset band resource in the unlicensed spectrum, a signal indicating that the communications device uses the unlicensed spectrum, where the preset band resource is a partial band resource in the unlicensed spectrum. Mutual interference between communications devices when the unlicensed spectrum is used is eliminated.
