|Title:||METHOD FOR DETERMINING CANDIDATE LINE-OF-SIGHT PATH, AND WIRELESS LOCAL AREA NETWORK DEVICE|
Disclosed are a method for determining a candidate line-of-sight path, and a wireless local area network device. In the method, a wireless local area network device receives a signal, which is wireless signals transmitted by means of multiple paths from a terminal to be recognized. Each wireless signal comprises a first training sequence, and the signal comprises a superposition of multiple first training sequences transmitted by means of the multiple paths. The wireless local area network device matches the signal with a second training sequence to obtain time points at which the multiple first training sequences transmitted by means of the multiple paths are received, the second training sequence being information stored by the wireless local area network device, and the first training sequence having the same value as the second training sequence. The wireless local area network device determines the path of a wireless signal which is received first as a candidate line-of-sight path. Only the angle of a line-of-sight path is estimated, and thus, the amount of calculation is reduced, the positioning delay is effectively shortened, and the occupation of air interface resources is also reduced.
