Patent ID: 7218948

Claim:
A method of transmitting pilot tones in a multi-sector cell including at least a first sector and a second sector, the second sector being located adjacent said first sector, the method comprising: transmitting, using a first tone, in said first sector during a first symbol time a first pilot signal having a first pre-selected transmission power; transmitting, using said first tone, in said second sector during a second symbol time, which overlaps said first symbol time, a second pilot signal having a second pre-selected transmission power which is different from said first pre-selected transmission power; transmitting, using a second tone, in said first sector during a third symbol time a third pilot signal having a third pre-selected transmission power; transmitting, using said second tone, in said second sector during a fourth symbol time, which overlaps said third symbol time, a fourth pilot signal having a fourth pre-selected transmission power which is different from said third pre-selected transmission power; transmitting, using a third tone, in said first sector during a fifth symbol time a fifth pilot signal having a fifth pre-selected transmission power; and transmitting, using said third tone, in said second sector during a sixth symbol time, which overlaps said fifth symbol time, a sixth pilot signal having said fifth pre-selected transmission power.
