Abstract

This application provides an uplink information sending method, including: determining, based on a transmission direction of a transmission resource and a preset grant-free transmission resource, a grant-free transmission resource used for uplink transmission, where the transmission resource includes the grant-free transmission resource; and sending uplink information on the grant-free transmission resource used for uplink transmission. According to the method, the grant-free transmission resource used for uplink transmission may be a subset of the preset grant-free transmission resource or may be a resource determined based on a location of the preset grant-free transmission resource. In either case, the grant-free transmission resource used for uplink transmission belongs to the transmission resource whose transmission direction is uplink transmission direction.
