Abstract: Embodiments of this application provide a communication method, device, and system. When a resource is reserved, a conflict between a reference signal of a terminal device and data transmission of another terminal device can be avoided, and impact on channel estimation performance of the terminal device can be avoided. In an embodiment, a network device determines resource configuration information, and sends the resource configuration information to the terminal device. The terminal device receives the resource configuration information, and determines, based on the resource configuration information, a symbol that corresponds to a first resource and that is in a first time unit. The symbol corresponding to the first resource does not include a symbol on which a reference signal is located and that is in the first time unit, and the first resource is not used for data transmission corresponding to the terminal device.
