Description

Communication method, communication device, and storage medium Technical Field The embodiment of the application relates to the technical field of communication, in particular to a communication method, a communication device and a storage medium. Background Base station energy conservation is an important research direction for future networks. The uplink of the time-domain off-Cell, i.e., the Cell discontinuous reception (Cell discontinuous reception, cell DRX) mechanism, has been supported in the new air interface (NR) protocol. Future network power savings will extend to all radio resource control (radio resource control, RRC) state users, including the RRC idle/inactive state. The inactive state user may use packet transfer (SMALL DATA transfer, SDT) for small amounts of data transfer, including packet transfer based on configuration-based authorized (configured grant, CG) resources, i.e., CG-SDT. When the terminal equipment initiates CG initial transmission (hereinafter referred to as initial transmission), it listens for the initially transmitted Response message, that is, CG Response. When the CG-SDT configuration grant weight transmission timer (CG-SDT-RetransmissionTimer) expires and the configuration grant timer (configuredGrantTimer) is not expired, the terminal device will automatically retransmit and continue to listen for CG responses. Wherein, the CG-SDT configuration grant weight transmission timer is used for uplink automatic retransmission. When the configuration grant timer is started, during the counting period, the configuration grant associated with the timer is considered valid, and the terminal device can perform data transmission based on the configuration grant. When the configuration grant timer expires and the terminal device still does not receive CG Response, the terminal device may consider the SDT to fail and then may revert to RRC Idle state. When Cell DRX is directly combined with CG-SDT, CG-SDT performance may be affected. Disclosure of Invention The application provides a communication method, a communication device and a storage medium, which are used for defining the transmission behavior of a terminal device when the network device is in a Cell DRX OFF state. The first aspect of the present application provides a communication method, optionally, the execution body of the method may be a first apparatus, and the first apparatus may be a terminal device, or a component or an apparatus (for example, a processor, a circuit, a chip, or a chip system) applied to the terminal device, or a logic module or software capable of implementing all or part of functions of the terminal device. Taking the terminal equipment as an example, the terminal equipment sends a first uplink signal, and the first uplink signal is used for waking up the network equipment on the first scheduling-free resource. And if the first downlink signal is received, the terminal equipment performs at least one of Random Access (RA) transmission, initial transmission on the first scheduling-free resource, subsequent transmission on the first scheduling-free resource or subsequent transmission on the second resource according to the first downlink signal, wherein the first downlink signal is a response signal of the first uplink signal. Based on the first aspect of the application, the network device is awakened by sending the first uplink signal, and whether the data can be sent on the first scheduling-free resource is determined according to the response of the network device to the first uplink signal, so that the transmission behavior of the terminal device when the Cell DRX of the network device is effective is clarified, and the probability of invalid transmission of the terminal device is reduced. In some possible embodiments, the second resource comprises any one of a first non-scheduled resource, a second non-scheduled resource, or a scheduled resource, based on the first aspect of the present application. In the embodiment of the application, the second resource used by the subsequent transmission is determined, so that the transmission behavior of the terminal equipment in the subsequent transmission is defined, and the probability of invalid subsequent transmission of the terminal equipment is reduced. Based on the first aspect of the present application, in some possible embodiments, the terminal device obtains first information, where the first information is used to indicate an association relationship between the first uplink signal and the first scheduling-free resource; In the embodiment of the application, the first uplink signal is associated with the first scheduling-free resource, so that the blind detection range of the receiver of the first uplink signal on the first uplink signal is reduced, and the power consumption of the receiver of the first uplink signal is saved.
