摘要： This application provides a secondary cell activation method and an apparatus, to help resolve a problem of an SCell activation failure caused by misalignment of transmit and receive beams of a high frequency CSI-RS signal. In embodiments of this application, in an SCell activation process, a terminal device reports receive beam direction information to a network device, so that the network device may adjust a transmit beam direction of a CSI-RS resource based on the receive direction information. In this way, the beam direction of the CSI-RS may be aligned with a receiving direction of the terminal device, and the terminal device may receive the CSI-RS resource and perform CSI measurement to obtain valid CSI information. Therefore, the SCell activation process is completed.

摘要： This application provides a measurement reporting method and an apparatus. The method includes: receiving pilot measurement configuration information of a plurality of carriers, where the pilot measurement configuration information of the plurality of carriers indicates a pilot association relation ship of the plurality of carriers, and the pilot association relationship of the plurality of carriers indicates that pilots of the plurality of carriers correspond to a same spatial domain transmit filter; performing measurement based on the pilot measurement configuration information of the plurality of carriers, to obtain measurement report results of the plurality of carriers; and sending the measurement report results of the plurality of carriers. The pilot association relationship of the plurality of carriers is configured for a terminal device, so that the terminal device may report, for the plurality of carriers, measurement results of the pilots corresponding to one or more same spatial domain transmit filters. In this way, when the plurality of carriers share one radio frequency channel, a network device can simultaneously use the plurality of carriers to communicate with the terminal device, that is, communication based on carrier aggregation is implemented. Therefore, communication efficiency can be improved.

摘要： This application provides 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. In this way, a network device in embodiments of this application can learn of a status of an antenna panel, and can properly schedule the antenna panel, thereby improving data transmission efficiency.
