Abstract
In some embodiments, multiple wireless communication devices that are each transmitting an acknowledgement to the same wide-channel transmission will transmit their acknowledgements simultaneously over different ones of the narrow channels that make up the wide channel, thereby permitting older devices that can't decode the wide channels to determine when the acknowledgement are transmitted.

A device for communicating in a wireless network, the device comprising a processor, a memory, and a radio, the device operative to:
- communicate a clear-to-transmit frame over a wide channel in a wireless communications network, the clear-to-transmit frame to contain a channel assignment in a channel assignment field of the clear-to-transmit frame, the channel assignment field identifying a first narrow channel for communicating an acknowledgement to a transmission;
- and
- communicate the acknowledgement over the first narrow channel;
- the wide channel comprising the first narrow channel and at least one other narrow channel.
A method of communicating in a wireless network, comprising:
- communicating a clear-to-transmit frame over a wide channel in the wireless communications network, the clear-to-transmit frame containing a channel assignment in a channel assignment field of the clear-to-transmit identifying a first narrow channel for communicating an acknowledgement to a transmission;
- and
- communicating the acknowledgement over the first narrow channel;
- the wide channel comprising the first narrow channel and at least one other narrow channel.
An article comprising a non-transitory computer-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- communicating a clear-to-transmit frame over a wide channel in the wireless communications network, the clear-to-transmit frame containing a channel assignment in a channel assignment field of the clear-to-transmit frame identifying a first narrow channel for communicating an acknowledgement to a transmission;
- and
- communicating the acknowledgement over the first narrow channel;
- the wide channel comprising the first narrow channel and at least one other narrow channel.
