Abstract

Some interference management measures in the PHY control to reduce possible interferences in the transmission between an MS and BSs are proposed. The design and assignment procedures to generate pilots to have lower interference levels are introduced and discussed. Based on the design process each pilot is accordingly assigned an interference weight with respect to a basic pilot and with this design in the system simulation by utilizing the generated pilots to IEEE 802.16m system it reveals that the system performance has 7.5 dB and 23 dB advantages in the interference levels for 7 BSs and 19 BSs respectively comparing with the conventional pilot design that assigns the pilots with the same interference weight for all BSs.
