METHOD AND SYSTEM FOR TRANSMITTING CHANNEL FEEDBACK INFORMATION

摘要

Disclosed are a method and system for transmitting channel feedback information. The method comprises: a sending station, after obtaining a Transmission Opportunity (TXOP), sends a radio frame to a receiving station and requests channel feedback information sent by the receiving station; the receiving station, after receiving the radio frame sent by the sending station, sends a radio frame carrying the channel feedback information to the sending station, wherein the sending end time point of the radio frame carrying the channel feedback information is allowed to exceed the end time point set by transmission time threshold value of the TXOP. The technical solution of present invention solves the technical problem that a sender is unable to timely obtain channel feedback information from a receiver, which enables the sender to remain timely obtain the channel feedback information from the receiver, in the case that the sender cannot estimate the data volume and rate of the channel feedback information fed back from the receiving station and whether the time of the channel feedback information fed back from the receiver exceeds the transmission time threshold value or not.
