Description

TECHNICAL FIELD The disclosure relates to the technical field of communication, and more particularly to a method for wireless communication, a terminal device and a communication device. BACKGROUND With the development of technology, changes have been taken place in the energy supply conditions of terminal devices. For example, one potential challenge that terminal devices may face is limited energy supply. Taking the zero power terminal as an example, the zero power terminal must harvest a certain amount of energy before it can drive itself to operate. In other words, the data transmission process of the zero power terminal device relies on external energy supply (such as wireless energy supply from the network). Before obtaining energy, the zero power terminal is in a "shutdown" state, that is, the zero power terminal is unable to receive signals sent from the peer end. Therefore, in some cases, data transmission is not only related to communication requirements and resource scheduling, but also to the energy supply condition of the terminal device.
