Description

Communication methods and related devices This application claims priority to Chinese Patent Application No. 202411555814.1, filed on October 31, 2024, entitled "Communication Method and Related Apparatus", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of communication technology, and in particular to communication methods and related devices. Background Technology With the development of communication technology, communication systems will possess sensing capabilities, and a single communication system can integrate wireless signal sensing and communication capabilities. For the mode of transmitting and receiving sensing signals between base stations and terminals, the sensing resources are configured by the base station, and the sensing signal transmission and reception operations are performed according to the configured resources. However, current terminal energy-saving or network energy-saving mechanisms are all aimed at communication services. If communication energy saving is not applied to sensing services, the power consumption of the sensing mode involving the terminal will be high, and it will occupy a large amount of resources. Therefore, how to reduce the power consumption of terminal-participated sensing modes and achieve more energy-efficient terminal-participated sensing modes is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention This application provides a communication method and related apparatus that can effectively reduce the power consumption of terminal-involved sensing modes and achieve more energy-efficient terminal-involved sensing modes. In a first aspect, embodiments of this application provide a communication method. This method can be applied to a first communication device, which may be, for example, a terminal device or a communication module within the terminal device, or a circuit or chip (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip) responsible for communication functions within the terminal device. The method includes: receiving a first message from a second communication device, wherein the first message carries first configuration information and second configuration information, the first configuration information being used to determine a transmission mode for a first sensing signal, and the second configuration information including discontinuous reception configuration information, which is used to determine time information for transmitting the first sensing signal. Based on the first configuration information and the second configuration information, the first sensing signal is transmitted, wherein the first sensing signal is used to generate first sensing data. Optionally, the discontinuous reception configuration information can be discontinuous reception (DRX) configuration information. Optionally, the transmission can be either receiving or sending. In this application, taking the first communication device as the terminal and the second communication device as the access network device as an example, on the one hand, the discontinuous reception configuration information issued by the access network device is usually used for communication services. However, in this solution, the first and second configuration information carried in the first message can be used to transmit the first sensing signal and perform sensing tasks. Specifically, the terminal in this application only needs to perform the sensing signal transmission operation according to the resources configured by the access network device (for example, determining the transmission mode of the first sensing signal according to the first configuration information issued by the access network device (for example, the terminal is the sender and the access network device is the receiver; or the terminal is the receiver and the access network device is the sender), and determining the time information for transmitting the first sensing signal according to the discontinuous reception configuration information issued by the access network device before transmitting the first sensing signal), which can effectively reduce the power consumption of the sensing mode involving the terminal and realize a more energy-efficient sensing mode with terminal participation. On the other hand, since the existing solutions do not cover scenarios where sensing signals are transmitted based on discontinuous reception configuration information issued by access network devices, the choice of application scenarios can be more diverse. In one possible implementation, transmitting the first sensing signal includes: transmitting the first sensing signal when a first condition is met. In the above embodiments, the operation of transmitting the first sensing signal by the subsequent terminal is initiated only when th
