First Claim
1. A wireless network, comprising:
- a first station, comprisinga media access control circuit configured to provide a frame of data to be transmitted on a communication channel; and
a physical layer device configured toreceive, from the media access control circuit, the frame of data, andtransmit the frame of data on the communication channel, wherein the physical layer device is configured to transmit the frame of data according to a first short interframe space (SIFS), and the physical layer device is also configured to transmit the frame of data according to a second short interframe space (SIFS), and wherein the first short interframe space (SIFS) has a duration that is different from that of the second short interframe space (SIFS),wherein the first SIFS associated with at least one of i) a first bandwidth of a plurality of bandwidth and ii) a first modulation and coding scheme of a plurality of modulation and coding schemes; and
a second station configured to i) determine, using stored or received information indicating that the first SIFS is associated with the at least one of the first bandwidth and the first modulation and coding scheme, which of the first SIFS and the second SIFS the first station used to transmit the frame of data, and ii) transmit a response to the frame of data based on determination of which of the first SIFS and the second SIFS the first station used to transmit the frame of data.

Abstract
A wireless network includes a first station and a second station. The first station includes a media access control circuit configured to provide a frame of data to be transmitted on a communication channel, and a physical layer device configured to receive the frame of data and transmit the frame of data on the communication channel. The frame of data is transmitted according to a first short interframe space (SIFS) or a second SIFS, and the first SIFS has a duration that is different from that of the second SIFS. The second station is configured to determine whether the first station transmitted the frame of data according to the first SIFS or the second SIFS and transmit a response to the frame of data based on the determination of whether the first station transmitted the frame of data according to the first SIFS or the second SIFS.
