Some demonstrative embodiments include devices, systems and/or methods of wireless communication over a combined channel. For example, a wireless communication unit may transmit a wireless communication transmission over a combined channel including a primary channel and at least one secondary channel, wherein the wireless communication unit is to begin the transmission over the combined channel if a detected state of use of the secondary channel is idle for at least a predefined silence period preceding an expiration of a back-off period corresponding to the primary channel, wherein the silence period is longer than a priority interframe space (PIFS) interval. Other embodiments are described and claimed. |
