Abstract
A method and apparatus for measuring an angle of arrival. The method includes: determining L×N values based on received values obtained by a first antenna array and a second antenna array by receiving a signal and determining an angle of arrival (AoA) of the first signal based on the L×N values. The first antenna array includes L rows of array elements arranged in a first direction and K columns of array elements arranged in a second direction. The second antenna array includes P rows of array elements arranged in the first direction and Q columns of array elements arranged in the second direction. N=K+Q. An included angle between the first direction and the second direction is greater than 0 degrees.
