METHOD AND APPARATUS FOR PERFORMING FREQUENCY SCAN FOR WIRELESS SYSTEMS WITH VARIABLE CHANNEL BANDWIDTH |
摘要 |
<p>Techniques for performing a frequency scan to detect wireless systems operating on frequency channels with variable bandwidths are disclosed. In one aspect, a user equipment (UE) performs a frequency scan for a plurality of frequency channels and measures the received power of each frequency channel based on a center frequency and a bandwidth of the frequency channel. The UE identifies candidate frequency channels for acquisition based on the results of the frequency scan. In another aspect, a frequency scan of a band is performed by partitioning the band into multiple segments, measuring received powers of subcarriers or raster frequencies within each segment, and concatenating received powers of subcarriers or raster frequencies for all segments. A frequency scan is then performed based on the concatenated results for the multiple segments.</p> |
