Abstract
System and method of wireless communication that enables determination of a proper channel bandwidth for an HT PPDU without requiring an earlier negotiation process. Assuming a TXOP does not involve any non-HT transmission, in case that TXOP duration information is specified in a first field in a previously transmitted HE PPDU in the same TXOP, the transmission opportunity (TXOP) holder utilizes the channel bandwidth specified in the initial HE PPDU of the same TXOP to determine the channel bandwidth for the subsequent PPDU. In the case that each previously transmitted PPDU has a value indicating duration unspecified in the first field, the TXOP holder determines the channel bandwidth for a subsequent PPDU based on the bandwidth specified in a preceding PPDU that has been transmitted in the same TXOP.
