METHOD AND SYSTEM FOR ADJUSTING DEMODULATION PILOT FREQUENCY IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method for adjusting a demodulation pilot frequency in a wireless communication system, comprising: acquiring at least one among a wireless channel characteristic parameter, device capability information, and system requirement information; configuring in real-time, on the basis of the wireless channel characteristic parameter/device capability information/system requirement information acquired, different demodulation pilot frequency patterns for different transmission during a transmission process; notifying a receiving-end device the demodulation pilot frequency patterns employed. The present invention also provides a corresponding system for adjusting the demodulation pilot frequency. The present invention is not only capable of adjusting the configuration of the pilot frequency on the basis of device performance and system requirement, but also capable of adjusting the configuration of the pilot frequency on the basis of changes in wireless transmission environment. This allows the configuration of the pilot frequency to adapt to changes in communication link, thus facilitating improved transmission reliability, and allowing increased average capacity for the system.
