Background The time delay is a key factor affecting the user experience, and is exemplified by extended Reality (XR) service, where XR is a time delay sensitive service, and the end-to-end time delay affects the user experience, so that there is a strict requirement on the time delay of air interface transmission. At present, the terminal can report the relevant information of the cached emergency data, such as the data quantity of the emergency data, the remaining time of the packet loss timer corresponding to the emergency data and the like, to the base station for the base station to schedule resources for the terminal. However, in the current resource scheduling manner, the data transmission quality of the emergency data needs to be improved. Disclosure of Invention The application provides a communication method and a communication device, which can improve the accuracy of resource scheduling, are beneficial to reducing the transmission delay of emergency data and improve the data transmission quality. In a first aspect, a communication method is provided, which may be applied to a terminal side, for example, a terminal or a communication module/processing module in the terminal, or a circuit or a chip in the terminal responsible for a communication function (such as a modem (modem) chip, also called a baseband (baseband) chip, or a system on chip (SoC) chip or a system-in-package (SYSTEMIN PACKAGE) SIP chip including a modem core), or a circuit or a chip in the terminal responsible for a processing function (such as a graphics processor (graphics processing unit, GPU), an artificial intelligence (ARTIFICIAL INTELLIGENCE, AI) processor, or an application-specific integrated circuit (ASIC)). The method comprises the steps of sending first information, wherein the first information indicates data quantity corresponding to a first reporting threshold, the first reporting threshold is the smallest reporting threshold in a plurality of reporting thresholds corresponding to time delay status reports (delay status reporting, DSR), the data quantity corresponding to the first reporting threshold comprises the data quantity of first data, and the first data comprises at least one of retransmission data, packet data convergence protocol (PACKET DATA convergence protocol, PDCP) control protocol data units (protocol data unit, PDU) or radio link control (radio link control, RLC).
