Abstract
Embodiments of the present invention provide systems and methods for synchronous independent channel access in a wireless network. The synchronous independent channel access can be performed by a wireless station having multiple transceivers for simultaneous communication over multiple wireless bands. A wireless station can connect wirelessly to a wireless access point to access a first primary wireless band during a transmission opportunity, and can use early access on a second primary wireless band without receiving a transmission opportunity. The transmission and reception of data frames over the different primary channels are synchronized to prevent or mitigate inter-channel interference. According to some embodiments, the channels are synchronized using back-off procedures and/or padding to align the ending time of transmitted and received data frames, for example.
