Ranging and distance based wireless link spectrum selection
First Claim
1. A method for performing spectral allocation for a wireless link in a wireless communication system wherein the method comprises the steps of:
- determining, with a modem, a distance/range for the wireless link; and
assigning a sub-carrier to the wireless link based on a value of the distance/range of the wireless link, and in accordance with a prioritization rule that requires assignment of a higher frequency sub-carrier to take priority over assignment of a lower frequency sub-carrier.

Abstract
A method and apparatus for performing spectral allocation for a wireless link in a wireless communication system is disclosed. The method determines a distance/range for the wireless link and assigns an optimal sub-carrier frequency to the wireless link based on (1) a higher frequency to lower frequency priority and (2) on the value of the distance/range of the wireless link. Higher frequency sub-carriers are assigned to wireless links that have a shorter distance/range and lower frequency sub-carriers are assigned to wireless links that have a longer distance/range. The method of the present work increases the spectral efficiency of the wireless communication system and improves system bandwidth.

8. A method for performing spectral allocation for a wireless link in a wireless communication system wherein the method comprises the steps of:
-
determining, with a modem, a distance/range for the wireless link; and selecting a plurality of sub-carriers to be input to a sub-carrier assignment process that assigns one of the plurality of sub-carriers to the wireless link based on Channel Impulse Response (CIR) information, wherein a sub-carrier chosen to be a highest frequency sub-carrier among said plurality of sub-carriers is identified based on said distance/range. - View Dependent Claims (9, 10)
