摘要： A transmission delay measurement method, a positioning method, a terminal, a base station and a storage medium. The transmission delay measurement method comprises: acquiring a downlink reference signal sent by a base station, and determining an LOS path and a reference path from a transmission path of the downlink reference signal (S110); acquiring a reference delay difference, wherein the reference delay difference is the difference value between a downlink transmission delay of the LOS path and a downlink transmission delay of the reference path (S120); sending an uplink reference signal to the base station, such that the base station acquires an uplink transmission delay of the reference path (S130); and reporting the reference delay difference to the base station, such that the base station obtains an uplink transmission delay of the LOS path according to the uplink transmission delay of the reference path and the reference delay difference (S140).

摘要： Disclosed are a method and apparatus for realizing beam alignment. The method comprises: when a first signal with effective strength is received by means of two analog sub-arrays, which have the same polarization manner, using receiving beams with the same beam direction, acquiring the first signals received by means of the two analog sub-arrays and the phase center difference between the two analog sub-arrays; maintaining the beam direction of the receiving beams of the two analog sub-arrays unchanged, changing the phase center difference between the two analog sub-arrays for the first time, and acquiring second signals received by means of the two analog sub-arrays and the phase center difference, which has been changed for the first time; maintaining the beam direction of the receiving beams of the two analog sub-arrays unchanged, changing the phase center difference between the two analog sub-arrays for the second time, and acquiring third signals received by means of the two analog sub-arrays and the phase center difference, which has been changed for the second time; and estimating a DOA of a received signal according to the obtained information, and directing the centers of the receiving beams to the estimated DOA.
