Pilot PN offset assigning method for digital mobile telecommunications system
First Claim
1. A method for assigning a pilot PN offset to a base station in a digital mobile telecommunications system, comprising the steps of:
- dividing a single cluster into a plurality of subclusters;
arranging a plurality of general base stations and reserved base stations, each having a plurality of sectors, in each of the subclusters; and
assigning a pilot PN offset to each sector, such that a PN offset difference between a sector and a next sector in the same base station is equal to a pilot increment times the number of subclusters in the cluster according to sector numbers, wherein the PN offset difference between the same sectors in corresponding base stations under different subclusters is equal to the pilot increment, and the PN offset difference between the same sectors in a current base station and a next base station under an identical subcluster is equal to the number of subclusters in the cluster×
the number of sectors in a base station×
the pilot increment.

Abstract
There is provided a method for assigning a pilot PN(PseudoNoise) offset to a base station in a digital mobile telecommunications system. In the pilot PN offset assigning method, a single cluster is divided into a plurality of subclusters, and a plurality of general base stations and reserved base stations, each having a plurality of sectors, are arranged in each of the subclusters. Then, a pilot PN offset is assigned to each sector, such that the PN offset difference between a sector and a next sector in the same base station is equal to a pilot increment times the number of subclusters in the cluster according to sector numbers, the PN offset difference between the same sectors in corresponding base stations under different subclusters is equal to the pilot increment, and the PN offset difference between the same sectors in a current base station and the next base station under an identical subcluster is equal to the number of subclusters in the cluster times the number of sectors in a base station×the pilot increment.
