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.
