Techniques for supporting system selection by user equipments (UEs) are disclosed. In one design, a UE may receive an indication that a first wireless system supports system selection by UEs. The UE may be within the coverage of a plurality of wireless systems, which may include the first wireless system. The UE may receive system selection information from at least one of the plurality of wireless systems. The system selection information may convey system loading, UE performance, system recommendation, etc. The UE may determine performance metrics for the plurality of wireless systems based on the system selection information. The UE may then select one wireless system among the plurality of wireless systems based on the performance metrics for the plurality of wireless systems and the indication that the first wireless system supports system selection by UEs.
