PCS THRESHOLD ADJUSTMENT METHOD AND TERMINAL APPARATUS FOR HIGH DENSITY WIRELESS NETWORKS

摘要

PURPOSE: A PCS critical value control method and a terminal device of a mobile network using the congestion of a shared channel are provided to improve the performance of the whole network by blocking PCS critical value control maximizing the spatial reuse. CONSTITUTION: An adjustment decision unit(210) decides the control of a PCS(PHYsical Carrier Sensing) critical value deciding the idle state of the shared channel based on the congestion of a shared channel. A critical value control unit(220) adjusts the PCS critical value based on a packet loss rate. A channel state determiner(230) decides the idle state of the shared channel based on the size of the signal from the mobile network and PCS critical value.
