摘要： Methods and systems for signaling on a mixed-mode wireless network comprising a plurality of channels are provided. The mixed-mode wireless network includes high-throughput (HT) wireless devices and legacy wireless devices that use channels of the same width. The HT devices transmit data on at least two channels, while the legacy devices transmit on one channel. The distances between the HT channels and the distances between the legacy channels might differ, however, the channels used by the HT devices and the legacy devices may overlap. As a result, cooperation between the HT devices and legacy devices is provided to enable the devices to coexist on the same wireless network by minimizing collisions and interference. The HT devices are configured to send control information to the legacy devices to coordinate transmission by the HT devices with the legacy devices.
