Apparatus and method for uplink scheduling in a broadband wireless communication system

A scheduling method in a broadband wireless communication system, the method comprising:

• ordering Collaborative Spatial Multiplexing (CSM) mobile stations according to priority levels of the CSM mobile stations;
• selecting the CSM mobile stations sequentially according to the priority levels;
• determining pilot patterns for the selected CSM mobile stations according to channel information of the selected CSM mobile stations;
• and
• allocating resources of the determined pilot patterns to the selected CSM mobile stations.

A scheduling method in a broadband wireless communication system, the method comprising:

• dividing channel conditions into at least two areas;
• determining an area corresponding to channel information of a Collaborative Spatial Multiplexing (CSM) mobile station received from the CSM mobile station;
• allocating resources of a first pilot pattern to the CSM mobile station, if the channel information belongs to an area with a good channel condition;
• and
• allocating resources of a second pilot pattern to the CSM mobile station, if the channel information belongs to an area with a poor channel condition.
