Abstract

A method and apparatus for monitoring other channel interference in wireless communication system are described. An OSI Monitor Set (OSIMonitorSet) is updated at the beginning of every superframe of a reverse link (RL) serving sector. A list of Pilot PN'"'"'s (PilotPN'"'"'s) of the sectors whose pilot strength (PilotStrenth) is larger than or equal to an other sector interference Monitor Threshold (OSIMonitorThreshold) in an OSIMonitorSet is provided, wherein the PilotPN and the PilotStrength are fields in an Overhead Parameter List (OverheadParameterList) of an Overhead Message Protocol and the OSIMonitorThreshold is a configuration attribute of the Overhead Message Protocol. The PilotPN of the reverse link Serving Sector (RLServingSector) are excluded. It is determined if the size of the list OSI Monitor Set Size (OSIMonitorSetSize) is larger than or equal to N_{OSIMonitorSet}, wherein N_{OSIMonitorSet} is a configuration attribute of the Overhead Message Protocol. Strongest PilotStrength of N_{OSIMonitorSet} PilotPN'"'"'s are kept.
