Abstract: A communication method of a wireless device to which a single radio frequency (RF) chain antenna is applied. The wireless device stores a plurality of beam sets for the single RF chain antenna and a plurality of quality values for the plurality of beam sets. The wireless device selects a first beam set having a first quality value that is a best quality value among the plurality of stored beam sets. The wireless device confirms a second quality value for the first beam set using received data when the data are received using the first beam set. The wireless device selects a second beam set different from the first beam set among the plurality of stored beam sets when the second quality value is poorer than the first quality value.
