WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION DEVICE SYSTEM

摘要

PROBLEM TO BE SOLVED: To avoid occurrence of reception errors by changing a specific frequency even when the reception errors frequently occur at the specific frequency in a TDMA type wireless communication system in which asymmetric communication can be executed utilizing frequency hopping. SOLUTION: A symmetric slot and an asymmetric slot are allowed to exist in the same frame. A frequency hopping pattern of the symmetric slot and that of the asymmetric slot are made identical. The frequency of the asymmetric slot can be automatically changed by changing that of the symmetric slot when the reception errors frequently occur. COPYRIGHT: (C)2006,JPO&NCIPI
