說明書
The base station first sends a high-frequency narrow beam of the region Bq1 to the mobile terminal in the region Bq1 according to the second scanning information, and the sending step lasts for T2. The mobile terminal separately receives, within T2 in the regions Un1, Un2, Un3, . . . , and UnP using P high-frequency narrow beams, the high-frequency narrow beam sent by the base station in the region Bq1. Afterwards, the base station sends a high-frequency narrow beam of the region Bq2 to the mobile terminal in the region Bq2. The mobile terminal separately receives, within T2 in the regions Un1, Un2, Un3, . . . , and UnP using P high-frequency narrow beams, the high-frequency narrow beam sent by the base station in the region Bq2. In such a sequence, the base station finally sends a high-frequency narrow beam of the region BqH to the mobile terminal in the region BqH. The mobile terminal separately receives, within T2 in the regions Un1, Un2, Un3, . . . , and UnP using P high-frequency narrow beams, the high-frequency narrow beam sent by the base station in the region BqH. The mobile terminal receives, using H×P high-frequency narrow beams in total, H high-frequency narrow beams sent by the base station in the H scanning sectors. After receiving the high-frequency narrow beams sent by the base station, the mobile terminal determines H×P receiving statistics of received signals on the H×P high-frequency narrow beams that are in a one-to-one correspondence with a third scanning sector and a fourth scanning sector, and records the H×P receiving statistics in an H×P matrix.
