Title:
ACTIVE ANTENNA UNIT DELAY ALIGNMENT METHOD AND APPARATUS AND ACTIVE ANTENNA UNIT
Document Type and Number:
WIPO Patent Application WO/2021/008532
Kind Code:
A1
Abstract:
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.
