A channel transmission method and system feedback information

The present invention provides a channel feedback transmission method and system information, comprising: a sending station acknowledgment requires the receiving station to re-transmit some or all of the channel feedback information, the current time point does not exceed the transmission time threshold point of time the end point, the transmission station transmits a radio frame to the receiving station, the receiving station resends the request part or all of the feedback information channel reservation time; radio frame carries the reservation time point of the end point of time is allowed to exceed a threshold transmission time point of the end point of time. By the present invention, can be solved since the transmission time limit threshold receiving station due to the problem can not be retransmitted segments failed transmission channel feedback information, avoiding a waste of bandwidth resources.
