Pilot PN offset assigning method for digital mobile telecommunications system

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 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 times the number of base stations in a subcluster—(the number of subclusters having no PN offsets in the last base stations thereof times the pilot increment) 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 the next base station under an identical subcluster is equal to the number of subclusters in the cluster times the pilot increment.

A method for assigning a pilot PN offset to a base station in a digital mobile telecommunications system, comprising the steps of:

• dividing each of a plurality of base stations into a plurality of sectors;
• arranging the base stations sequentially from an innermost tier to an outermost tier, centering on a reference base station in a single cluster;
• 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 a pilot increment according to sector numbers, and the PN offset difference between the same sectors in a current base station and the next base station is equal to the number of sectors in a base station times the pilot increment.

A method for assigning a pilot PN offset to a base station in a digital mobile telecommunications system, comprising the steps of:

• dividing each of a plurality of base stations into a plurality of sectors;
• arranging the base stations nonsequentially from an innermost tier to an outermost tier, centering on a reference base station in a single cluster;
• 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 a pilot increment according to sector numbers, and the PN offset difference between the same sectors in a current base station and a next base station is equal to the number of sectors in a base station times the pilot increment.
