Claim of US Patent No. 9,094,970

1. A method for achieving backward compatibility in a large bandwidth wireless network, comprising:
sending/receiving, by an Access Point (AP), wireless frames on channels belonging to a first channelization set and a second
channelization set respectively and alternately in terms of time according to a communication protocol, the wireless frames
comprising at least one of the followings: wireless control frames, wireless management frames and data wireless frames;

and the method further comprising:
sending, by the AP, control and management information and system configuration information or system configuration information
belonging to each channelization solution on a primary channel belonging to the first channelization set and a primary channel
belonging to the second channelization set respectively and alternately in terms of time;

wherein the AP sends the system configuration information, or the system configuration information and the control and management
information through broadcast or unicast and notifies a Non-AP STA associated with the AP that a Basic Service Set (BSS) to
which the Non-AP STA associated with the AP belongs performs switching of working channels between the first channelization
set and the second channelization set;

the system configuration information at least comprises one of the following parameters: primary channel configuration parameters
and the time window parameters of the BSS working on a corresponding channelization set;

the control and management information is configured to, in an explicit manner, notify the BSS to perform the switching of
the working channels between the first channelization set and the second channelization set.
