摘要： Embodiments of the present application provide a wireless communication method, a terminal device, and a network device. The method comprises: sending first indication information, wherein the first indication information is used to indicate first parameters, and the first parameters are used to represent a first energy collection efficiency and/or first time interval of a terminal device. By means of the indicated first parameters, the network device may be enabled to know the energy collection efficiency or time interval of the terminal device. Thus, when the network device performs downlink transmission or uplink scheduling, communication parameters may be determined according to the energy collection efficiency or time interval indicated by a zero-power device, which reduces invalid transmission or scheduling, conserves transmission resources, reduces delay, and improves the system performance of zero-power communication.

摘要： Embodiments of the present application provide a wireless communication method, a terminal device, and a communication device. The method comprises: determining a type or terminal group to which a terminal device belongs; sending a backscattered signal on the basis of a transmission resource, fallback parameter, or time unit corresponding to the type or terminal group to which the terminal device belongs. In the present application, different transmission resources, fallback parameters, or time units are designed for terminal devices of different types or different groups, such that resource conflicts between the terminal devices of different types or different groups can be avoided, and the reliability of data transmission is improved. In particular, for an energy-constrained terminal device such as a terminal device that requires energy collection and storage between communications and is far away from a network device, the energy collected or stored by the terminal device can be saved and the energy utilization efficiency is improved, such that energy requirements during communication can be met.
