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 transmission (Cell discontinuous transmission, cell DTX) 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 DTX 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 DTX 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 first request information, wherein the first request information is used for requesting downlink resources for carrying feedback of uplink transmission, the uplink transmission is transmission using scheduling-free resources, and the uplink transmission comprises initial transmission and/or subsequent transmission. If the first response information is received, the terminal device performs at least one of 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 response information, where the first response information is response information of the first request information. Based on the first aspect of the application, the terminal equipment reserves the downlink resource for bearing the uplink transmission feedback by sending the first request information, and determines whether the data can be sent on the first scheduling-free resource according to the first response information, thereby defining the transmission behavior of the terminal equipment when the Cell DTX takes effect, and further ensuring the reliability of transmission. In some possible implementations, the second resource includes 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. In some possible embodiments, the first request information is carried on the first uplink signal, and the terminal device further receives configuration information, where the configuration information is used to indicate the configuration of the first uplink signal and the first downlink signal. In the embodiment of the application, based on the configuration information, the terminal equipment and the network equipment can determine the associated uplink signal or downlink signal according to the configuration information, thereby reducing the blind detection range of the netw
