Abstract
This application provides a wireless communication method performed by a terminal or a chip of the terminal, and the method includes: receiving higher layer signaling from a base station, where the higher layer signaling is used to configure a first time resource and a first frequency resource that can be used for uplink transmission without scheduling; and receiving downlink control information indicating a format of a slot, where the format indicates a transmission direction of a symbol in the slot, and an uplink symbol in the slot is a time resource that can be used for the uplink transmission without scheduling. In the method, a time resource that is dynamically allocated by the base station to the terminal via the downlink control information and that can be used for uplink transmission without scheduling is received.
