Pattern-based polling of mobile stations for channel quality information

摘要

A channel quality information (CQI) polling controller for use in a wireless communication network is capable of causing a base station to poll a mobile station within its coverage area for CQI at an initial predetermined rate. The controller is also capable of recognizing a CQI variation pattern of the mobile station based upon its responses to a plurality of the CQI polls. The controller is further capable of selecting a CQI polling rate based upon the recognized CQI variation pattern. The controller is also capable of causing the base station to poll the mobile station for CQI at the selected CQI polling rate.
