Method and apparatus for performing frequency scan for wireless systems with variable channel bandwidth

An apparatus for wireless communication, comprising:

• circuitry configured to:
• perform a frequency scan for a plurality of frequency channels based on a center frequency and a bandwidth of each of the plurality of frequency channels;
• and
• identify candidate frequency channels for acquisition based on results of the frequency scan.

A computer program product, comprising:

• a non-transitory computer-readable medium comprising:
• code for causing at least one computer to perform a frequency scan for a plurality of frequency channels based on a center frequency and a bandwidth of each of the plurality of frequency channels;
• and
• code for causing the at least one computer to identify candidate frequency channels for acquisition based on results of the frequency scan.

A method for wireless communication, comprising:

• determining a band to scan, the band covering a plurality of raster frequencies;
• partitioning the band into a plurality of segments covering different portions of the band;
• determining received powers of a plurality of subcarriers within each of the plurality of segments;
• determining received powers of the plurality of raster frequencies within the band based on the received powers of the plurality of subcarriers within each of the plurality of segments;
• and
• performing a frequency scan based on the received powers of the plurality of raster frequencies within the band.
