摘要： A method of sounding and feedback with channel quality information and reduced overhead is provided. A receiving station receives a sounding signal transmitted from an access point over multiple sub-channels of a wide channel in a wireless network. The receiving station detects channel quality based on the received sounding signal for each sub-channel. The receiving station then performs channel estimation based on the received sounding signal and thereby determining feedback information. Finally, the receiving station transmits a feedback message to the access point, the feedback message contains NULL feedback information, reduced feedback information, or channel integrity/quality indicators based on the channel quality information for each sub-channel. Based on the feedback message, the access point may repeat the sounding process, narrow the transmission bandwidth, or select only stations who have indicated uncorrupted channel sounding for MU-MMO transmission.

摘要： A communication method that operates by determining a first set of physical parameters of a first channel by a coordinator in a wireless communication system; establishing communication with a first set of devices over the first channel; determining a protection period in accordance with a pre-determined rule; broadcasting a channel-adjustment message, wherein the channel-adjustment message comprises a set of instructions for indicating how to adjust from the first channel to a second channel, and the set of instructions comprise channel bandwidth information for indicating how to adjust to a bandwidth of the second channel and central frequency information for indicating how to adjust to a central frequency of the second channel; and communicating with a second set of devices over the second channel during the protection period.
