說明書
In another embodiment of the present disclosure, after the mobile terminal sends, to the base station according to the foregoing method using the low frequency channel, the first serial number corresponding to the scanning sector on the base station side and the second serial number corresponding to the scanning sector on the mobile terminal side, where the first serial number and the second serial number correspond to the matrix element with maximum power, or after the mobile terminal sends a Q×N matrix to the base station using the low frequency channel, the base station and the mobile terminal exchange, using the low frequency channel, information indicating that fine scanning continues to be performed, that is, determine second scanning information. For example, the base station and the mobile terminal agree on a scanning sub-sector division manner or a quantity of scanning sub-sectors of a scanning sector corresponding to the first serial number and a scanning sub-sector division manner or a quantity of scanning sub-sectors of a scanning sector corresponding to the second serial number. It is assumed that the quantity of scanning sub-sectors of the scanning sector corresponding to the first serial number is H, and the quantity of scanning sub-sectors of the scanning sector corresponding to the second serial number is P. The H scanning sub-sectors are separately denoted as Bq1, Bq2, Bq3, . . . , and BqH, and the P scanning sub-sectors are separately denoted as Un1, Un2, Un3, . . . , and UnP. The base station sends a high-frequency narrow beam to the mobile terminal in a third scanning sector according to the second scanning information, and the mobile terminal receives the high-frequency narrow beam in a fourth scanning sector. The third scanning sector is any one of the H scanning sub-sectors, and the fourth scanning sector is any one of the P scanning sub-sectors.
