Title:
CORRECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/105346
Kind Code:
A1
Abstract:
Provided in the present application are a correction method and apparatus relating to the technical field of communication, and being capable of reducing correction error between RRU and increasing correction precision. The method comprises: an RRU control apparatus receives resource configuration information sent by a centralised control apparatus, the time frequency resources indicated by the resource configuration information being used for sending and receiving correction signals between said RRU and n other RRU, the n other RRU being RRU 1 level apart from said RRU in the correction path of the correction path topology, and the number of levels of the shortest correction path between any two RRU in the correction path topology being less than or equal to a level threshold; on the basis of the resource configuration information, controlling said RRU to send and receive correction signals over the time frequency resources; on the basis of the correction signals sent and received by said RRU, acquiring m sets of path information; on the basis of the m sets of path information, acquiring m correction coefficients; and using the m correction coefficients to compensate M channels of said RRU.
