Abstract
The disclosure discloses a method for distributing pilot frequency in a massive antenna system, including: dividing a pilot frequency set into three sub sets that are intersecting with each other, and then dividing the users of each cell into a cell central user and a cell edge user. The cell central users use an intersection set of three pilot frequency sub sets. The cell edge users of all cells use a difference set, an intersection set and a union set of three pilot frequency sub sets according to a certain rule. When it is designing to implement the pilot resource distribution plan of the massive antenna system, three cells that are adjacent with each other in the system are used as a cluster, and a pilot frequency use plan of any one cluster may be designed according to the method proposed by the disclosure, and then the same design plan is applied to other clusters in the system, and then is adjusted according to the user distribution of each cluster and the business distribution circumstance thereof.
