1. A method of selecting a pseudo-noise (PN) offset for a newly deployed sector in a mobile communication network, said method comprising: determining a neighbor list including neighbor sectors of the new sector; determining an initial PN offset list including a list of PN offsets and corresponding sectors; eliminating PN offsets from the initial PN offset list based on the neighbor list; determining a first priority factor for surviving PN offsets in the PN offset list based on a sector azimuth of the new sector, sector azimuths of the sectors assigned the candidate PN offsets, or both; ranking the surviving PN offsets based on the first priority factor and distance of the assigned sector from the new sector; selecting a PN offset based on the ranking; and configuring a transmitter in the new sector to transmit a PN sequence with the selected PN offset.
