JUDGMENT METHOD AND WIRELESS COMMUNICATION APPARATUS
A determining method which is executed by a radio communication device includes a radio step of executing a radio communication, using two or more directional beams selected from a plurality of directional beams; and a determination step of determining which of line-of-sight waves and reflected waves is used for the executed radio communication, on the basis of an amount of variation in directions between the two or more directional beams used at different times. The determination step includes determining that the executed radio communication is radio communication using the reflected waves, when the amount of variation is equal to or greater than a threshold value.
1 . A determining method which is executed by a radio communication device, the method comprising:
executing a radio communication, using two or more directional beams selected from a plurality of directional beams; and
determining which of line-of-sight waves and reflected waves is used for the executed radio communication, on the basis of an amount of variation in directions between the two or more directional beams used at different times.
2 . The determining method according to claim 1 ,
wherein determining that the executed radio communication is radio communication using reflected waves, when the amount of variation is equal to or greater than a threshold value.
3 . A radio communication device comprising:
a radio communicator which executes a radio communication, using two or more directional beams selected from a plurality of directional beams; and
a determiner which determines which of line-of-sight waves and reflected waves is used for the executed radio communication, on the basis of an amount of variation in directions between the two or more directional beams used at different times.
4 . The radio communication device according to claim 3 ,
wherein the determiner determines that the executed radio communication is radio communication using reflected waves, when the amount of variation is equal to or greater than a threshold value.
