Cell selection handoff for cdma2000 1x advance

A method for a mobile apparatus which is wirelessly coupled to a plurality of base station, comprising:

• estimating a power level for a plurality of pilot signals that each correspond to one of the plurality of base stations;
• selecting at least one base stations for blanking in response to said power levels of pilot signals of corresponding base stations, the selected base stations are indicated in a plurality of bits;
• and
• generating a plurality of cell selection feedback signals indicating said plurality of corresponding base stations, wherein each of the cell selection feedback signal is transmitted to said plurality of corresponding base stations, and said cell selection feedback signal directs said one or more corresponding base stations to perform said blanking.

A base station wirelessly coupled to a mobile apparatus, comprising:

• a pilot signal generator, configured to generate a pilot signal corresponding to the base station, wherein the pilot signal comprising a plurality of sub-frame units;
• a receiver, configured to received a cell selection feedback signal which indicates whether the base station is selected by the mobile apparatus, the cell selection feedback signal is calculated by the mobile apparatus according to the pilot signal;
• and
• a processor, coupled to the pilot generator and the receiver, if the base station is selected, the processor is configured to perform hand off and communicate with the mobile apparatus.
