Abstract: Embodiments of this application disclose a blocked antenna alarm method, and a communication chip and device that relate to the chip field. The embodiments resolve a problem where a communication device cannot prompt a user that an antenna of the communication device is blocked. In the method, the communication chip obtains an attenuation value of an air interface loopback signal through an antenna of the communication device. The communication chip then determines, based on the attenuation value, whether the antenna is blocked. When it is determined that the antenna is blocked, the communication chip indicates a processor of the communication device to output, to a user, alarm information indicating that the antenna is blocked.
