1. A communication method, comprising:
determining that a data type is extended reality data;
obtaining an extended reality quality indicator (XQI) information corresponding to a target rate, the obtaining being based on the data type, a delay information, and a transmission error information, the XQI information indicating a transmission quality of the extended reality data, the XQI information corresponding to an extended reality base layer data stream and an extended reality enhancement layer data stream;
performing communication based on the XQI information; and
obtaining first evaluation information and second evaluation information, the first evaluation information indicating a source quality of the extended reality data and the second evaluation information indicating a capability of processing the extended reality data;
wherein the source quality of the XR data is used to evaluate one or more of: an image quality definition, an image smoothness, an image stereoscopy, an image distortion, a frame rate, or an audio quality; and
wherein the capability of processing the XR data is used to evaluate a capability of one or more of: a supported FOV angle or a refresh rate.
