Method and apparatus for determining channel bandwidth

摘要

In a method implemented in a communication device an available bandwidth for transmitting one or more data frames is determined, wherein the available bandwidth corresponds to a first composite communication channel comprising a plurality of communication channels. A control frame to indicate a request to transmit via the first composite communication channel is generated, wherein the control frame includes a header, and wherein a portion of the header includes information indicating the bandwidth of the first composite channel. The control frame is transmitted via the first composite communication channel, wherein at least the portion of the header is duplicated in a plurality of bandwidth portions of the first composite communication channel.

1. A method implemented in a first communication device, the method comprising:
determining, by the first communication device, a first idle bandwidth at the first communication device for transmitting a request for a determination of a second idle bandwidth at a second communication device, wherein the first idle bandwidth corresponds to a first composite communication channel that comprises at least three 20 MHz communication channels; generating a control frame that indicates the request for the determination of the second idle bandwidth, wherein the control frame includes a header, and wherein a portion of the header includes information indicating the first idle bandwidth at the first communication device; and causing the control frame to be transmitted to the second communication device via the first composite communication channel, wherein at least the portion of the header is duplicated in the at least three 20 MHz communication channels.
