ACTIVE ANTENNA UNIT DELAY ALIGNMENT METHOD AND APPARATUS AND ACTIVE ANTENNA UNIT

Disclosed in the embodiments of the present invention are an active antenna unit delay alignment method and apparatus, and an active antenna unit, the method comprising: on the basis of a front-haul interface protocol, generating an air interface synchronisation identifier; on the basis of the air interface synchronisation identifier, generating an alignment identifier and, on the basis of the alignment identifier, aligning the antenna data delay. By means of the technical solution of the air interface synchronisation identifier, the present method can automatically correct delays, and can take into consideration large range and high precision delay alignment requirements, thereby solving the problems in the prior art of fixed compensation values and being unable to implement automatic correction. Selon des modes de réalisation, la présente invention porte sur un procédé et un appareil d'alignement de retard d'unité d'antenne active, et sur une unité d'antenne active, le procédé comprenant : sur la base d'un
