Method and system for transmitting channel feedback information

摘要

The disclosure provides a method and system for transmitting channel feedback information. The method includes: a transmitting station transmits, after obtaining a Transmission Opportunity (TXOP), a radio frame to a receiving station to request the receiving station to transmit channel feedback information; and the receiving station transmitting, after receiving the radio frame transmitted by the transmitting station, a radio frame including channel feedback information to the transmitting station, wherein a transmission end time of the radio frame including channel feedback information is allowed to exceed an end time set by a transmission time threshold of the TXOP. The technical solution of the disclosure solves the technical problem that the transmitter is unable to timely obtain channel feedback information from the receiver, enabling the transmitter to timely obtain the channel feedback information from the receiver even in the condition that the transmitter cannot estimate a data volume and a rate of the channel feedback information fed back from the receiving station and whether the time for feeding back the channel feedback information by the receiver would exceed the transmission time threshold value or not.

1. A method for transmitting channel feedback information, comprising:
after obtaining a Transmission Opportunity (TXOP), transmitting, by a transmitting station, a radio frame to a receiving station to request the receiving station to transmit channel feedback information; and after receiving the radio frame transmitted by the transmitting station, transmitting, by the receiving station, a radio frame including channel feedback information to the transmitting station, wherein a transmission end time of the radio frame including channel feedback information is allowed to exceed an end time set by a transmission time threshold of the TXOP; receiving, by the transmitting station, the radio frame including channel feedback information from the receiving station even in a condition that the transmission end time of the radio frame including channel feedback information exceeds the end time set by the transmission time threshold of the TXOP, wherein an end time pointed by a preset time included in the radio frame transmitted by the transmitting station is allowed to exceed an end time pointed by a transmission time limit (TXOP Limit).
