    摘要: Described is a system and method for transporting interference-related control data and other information between nodes in a wireless network, using a control channel that is distinct from a content channel used to transport content. The control channel may be a different channel in the same unlicensed band as the content channel, a channel in a different unlicensed band, or a channel in a licensed band, and thereby not subject to the same interference-related problems that the unlicensed content channel may experience. As a result, management information for adjusting the content channel's communication parameters may still be communicated between the nodes, whereby mitigation actions may occur. For example, the content channel may be changed to another frequency, compression may be implemented or varied, and/or the data transfer rate may be varied. The control data can also be used to change the control channel's communication parameters.
