Abstract: A first communication device generates a first physical layer (PHY) data unit that includes information indicating a capability to use a channel bandwidth greater than a maximum channel bandwidth of the first communication device, and transmits the first PHY data unit to a second communication device during an association process with the second communication device. The first communication device generates a second PHY data unit that includes information indicating a capability to use at most the maximum channel bandwidth of the first communication device, and transmits the second PHY data unit to the second communication device when the first communication device is associated with the second communication device.

Abstract: The invention provides a NC control method and a NC control apparatus for implementing the method. The method comprises: acquiring a first NC code and a second NC code, wherein the first NC code comprises first machining information for controlling a tool to machine a workpiece, and the second NC code comprises second machining information for enhancing the first machining information; simultaneously running the first NC code and the second NC code to parse out the first machining information and the second machining information; merging the first machining information and the second machining information; and controlling the tool to machine the workpiece according to the result of the merging. The invention also provides a NC control apparatus and a computer storage medium for machining controlled both by the first and the second NC code.
