Dynamic channel assignment
First Claim
Patent Images
1. A method for dynamic channel assignment in a time division multiple access (TDMA) scheme, comprising:
- sweeping a narrow band filter through a predetermined frequency range to measure an average energy for each of a plurality of time slots;
selecting a time slot based on a comparison of average energies corresponding to the time slots;
assigning a selected time slot; and
assigning a frequency hopping pattern for use within the selected time slot.

Abstract
This invention provides interference predictions, suitable for least interference dynamic channel assignment use or other frequency hopping uses by de-coupling the time slot assignment and the frequency hopping pattern assignment. In particular, a least interfered time slot is selected based on an aggregate interference measurement performed across an entire transmission band or a pre-specified range of frequencies in the transmission band. A user is assigned a least interfered time slot and provided an appropriate frequency hopping pattern.
