Abstract
Embodiments of the present disclosure provide a signal processing method and a signal processing device, which relate to the field of communication technology and used for the purpose of saving signaling resources. The signal processing method provided by embodiments of the present disclosure includes: transmitting a first indication message to a terminal device, wherein the first indication message is to trigger the terminal device to transmit feedback information on pilot signals; transmitting N downlink pilot signals to the terminal device, where N is an integer greater than or equal to 2, and the transmission manner of the N downlink pilot signals is semi-persistent transmission or aperiodic transmission, so that the terminal device, according to an acquired precoding manner of the downlink pilot signals and the first indication message, determines a feedback manner of the feedback information on the N downlink pilot signals and performs feedback, and wherein the feedback manner includes not feeding back or one-time feeding back of the feedback information on the N downlink pilot signals. In the embodiments of the present disclosure, the base station or the terminal device may not transmit feedback information on a plurality of pilot signals, or may one-time transmit feedback information on a plurality of pilot signals, thereby effectively saving signaling resources.
