Introduction
• Signaling necessary for interference management
must be covered by SDD
• This contribution provides a summary and analysis of
signaling requirements by interference management
methods
• Analysis based on 27 interference management
contributions submitted until session #55
• Focus on UL signaling requirements
Common UL Signaling
• Interfering Cell ID
• Interference reduction request
• Precoding vector (or precoding vector index with
codebook based approach) with respect to interfering
BS
• Preamble SINR
• Data region SINR
• Long term SINR
Non-Interference Mitigation Specific
Signaling
• Preamble SINR
• Data region SINR
Interference Mitigation Specific Signaling
• Interfering Cell ID
• Interference reduction request
• Precoding vector / precoding vector index with
respect to interfering BS
• (Long term SINR  can be obtained at BS)
Interference Mitigation Example
Efficient MIMO downlink intercell interference cancellation using pre-coding (IEEE
C802.16m-08/449)

Desired Signal
Interfering Signal
Signaling
• Precoding vector with respect to interfering BS must
be signalled from User b1 to BS A
Proposed SDD Text
11.x Interference Mitigation
11.x.1 Measurement and Reporting
A mobile station may feedback the following
interference management related information:
• Interfering Cell ID
• Interference reduction request
• Precoding vector (or precoding vector index with
codebook based approach) with respect to interfering
BS
