Abstract: A method and an apparatus for determining a status of an antenna panel. A terminal receives configuration information including at least one downlink signal resource set. When determining that a first antenna panel corresponding to a first downlink signal resource set is turned on, the terminal measures quality of a resource in the first downlink signal resource set by using the first antenna panel, and sends first feedback information. The first feedback information may indicate the quality of the resource in the first downlink signal resource set. When the first antenna panel is turned off, the terminal skips measuring the quality of the resource in the first downlink signal resource set, and sends second feedback information. The second feedback information is used to indicate that the first antenna panel is turned off.
