Communication method, communication device, and storage medium

A communication device, comprising an antenna assembly and a switch assembly,

• wherein the antenna assembly is configured to communicate with a second device, and the antenna assembly comprises a first antenna, a second antenna, and a third antenna;
• and
• the switch assembly is configured to control the antenna assembly to receive, at a first moment, first data from the second device through the first antenna and second data from the second device through the second antenna,
• wherein a distance between the first antenna and the second antenna is a first distance, a distance between the first antenna and the third antenna is a second distance, the first distance and the second distance are greater than a first threshold, a distance between the second antenna and the third antenna is a third distance, the third distance is less than a second threshold, and the first threshold is greater than or equal to the second threshold;
• and
• the switch assembly is further configured to control the antenna assembly to receive, at a second moment, third data from the second device through the first antenna and fourth data from the second device through the third antenna;
• and
• the communication device further comprises a CPU, wherein the CPU is configured to obtain first channel state information CSI based on the first data, obtain second CSI based on the second data, obtain third CSI based on the third data, and obtain fourth CSI based on the fourth data;
• and obtain angle-of-incidence information of the second device relative to the communication device based on the first CSI, the second CSI, the third CSI, and the fourth CSI.
