Can some one help, what is meant by CINR Reuse 1 ,CINR Reuse 2 and CINR in Wimax CPE?

hi again suresh

CINR reuse "K" is a "frequency reuse factor" and it is a ratio of the reused frequency resources in the comm. systems. the frequency reuse factor is determined according to the number of cells/sectors that do not use the same frequency resource.
in general, if there is a cell which located nearby a BS allocates a resource with K=1 to a SS/MS coz it has a higher CINR. a on the contrary, a cell boundary which located farther from the BS allocates a resource with K>1 to the SS/MS coz it has a lower CINR. in this manner, the BS or upper node uses a different frequency reuse factor according to a channel state in the process of allocating a resource to the MS, thereby increasing resource effuciency.
Therefore, in the IEEE 16 system, a BS uses the frame in which a frequency reuse factor "1" and a frequency reuse factor 'K' caexist, in order to provide smooth service or safely transmit important information such as control information to an MS located in the cell boundary.

i attach u an paper which talking about the usage of "frequency reuse factor" in 16e system.

Ahmad
check the attached paper for more deail's

good luck

Not sure if this query is outdated but here goes from Channel Quality Reporting in IEEE 802.16e WiMAX document:

For the frequency reuse = 1, the reported CINR shall be the estimate of the average CINR over all subcarriers of the preamble except the guard subcarriers and the DC subcarriers. In other words, the signal on the unmodulated subcarriers (except the guard subcarriers and the DC subcarriers) shall also be considered as noise and interference for the CINR estimate of the frequency reuse = 1. The reported value shall represent the average CINR on non-boosted data subcarriers of the first zone in the frame; hence preamble boosting shall be compensated for in both desired signal and interference/noise calculation.

For the frequency reuse configuration=3 type, the reported CINR shall be the estimate of the CINR over the modulated subcarriers of the preamble.

CINR displayed in CPE usually refers to the preamble CINR.
Dear Ahmad
Do you know , How can i manage the physical profile in opnet , for frequency reuse 3?
Thank you.
