Beam setting method, beam setting apparatus and program

A beam setting method comprising:

• predicting a communication method performed on the basis of whether there is a line-of-sight between a first radio station device and a second radio station device;
• setting the number of beams transmitted by a beam sweep, in which signals using formable beams are sequentially transmitted in a time-division manner, to a number larger than a set number when it is predicted by predicting the communication method that communication is performed by a communication method using reflected waves;
• and
• setting the number of beams transmitted by the beam sweep to a number smaller than the set number when it is predicted by predicting the communication method that communication is performed by the communication method using line-of-sight waves.

A beam setting device comprising:

• a memory storing instructions;
• at least one processor connected to the memory and executes the instructions to:
• predict a communication method performed on the basis of whether there is a line-of-sight between a first radio station device and a second radio station device;
• set the number of beams transmitted by a beam sweep, in which signals using formable beams are sequentially transmitted in a time-division manner, to a first constant when it is predicted by predicting the communication method that communication is performed by the communication method using reflected waves;
• and
• a second beam number setting unit which sets the number of beams transmitted by the beam sweep to a second constant smaller than the first constant when it is predicted by predicting the communication method that communication is performed by the communication method using line-of-sight waves.

A non-temporal storage medium storing a program which causes a computer to execute the beam setting method comprising:

• predicting a communication method performed on the basis of whether there is a line-of-sight between a first radio station device and a second radio station device;
• setting the number of beams transmitted by a beam sweep, in which signals using formable beams are sequentially transmitted in a time-division manner, to a first constant when it is predicted by predicting the communication method that communication is performed by the communication method using reflected waves;
• and
• setting the number of beams transmitted by the beam sweep to a second constant smaller than the first constant when it is predicted by predicting the communication method that communication is performed by the communication method using line-of-sight waves.
