Method for coverage optimization of multi-frequency assignment system

A method for optimizing coverage of a multi-frequency assignment system of a wireless communications system, so as to equalize coverage for each frequency assignment, said wireless communications system including at least first and second base stations allocated for respective geographic cells, with said first base station configured to transmit communication signals to subscriber terminals using at least a first frequency allocation (FA#1) and a second frequency allocation (FA#2), said second base station configured to transmit communication signals to subscriber terminals using said FA#1 substantially more frequently than said FA#2, said method comprising the steps of:

• (a) checking paths of forward and reverse links using a power allocation ratio for a dummy pilot at FA#2 transmitted by said second base station, said dummy pilot power allocation ratio being sufficient to substantially equalize a handoff boundary between said first and second cells for handoffs at said FA#1 and FA#2;
• (b) confirming a transmit attenuation value (Tx_Atten) for FA#1;
• (c) reducing a value of Tx_Atten for FA#2 by a predetermined amount relative to said value of Tx_Atten for FA#1;
• (d) measuring radio frequency (RF) output of FA#2;
• (e) comparing the RF output value for FA#1 to said measured RF output value for FA#2;
• (f) adjusting the value of Tx_Atten for FA#2 by an amount in accordance with said dummy power allocation ratio, so that RF output power for said dummy pilot is less than RF output power for a pilot channel at FA#1 of said second base station according to said dummy pilot allocation ratio, whereby said handoff boundary is substantially equalized in an environment of more communication traffic and interference at FA#1 than for FA#2.
