METHOD AND APPARATUS FOR UTILIZING OTHER SECTOR INTERFERENCE(OSI) INDICATION

摘要

Techniques for mitigating interference in a wireless communication system are described. In one design, a sector may determine multiple fast other se ctor interference (OSI) indications for multiple subzones, with each subzone corresponding to a different portion of the system bandwidth. At least one report may be generated for the multiple OSI indications, with each report i ncluding at least one OSI indication for at least one subzone. Each report m ay be encoded to obtain code bits, which may then be mapped to a sequence of modulation symbols. A sequence of modulation symbols of zero values may be generated for each report with all OSI indications in the report set to zero to indicate lack of high interference in the corresponding subzones. This a llows a report to be transmitted with zero power in a likely scenario. A reg ular OSI indication may also be determined for the system bandwidth and tran smitted.
