    • Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. A first device (100) includes a control component (130) that generates control information and an interference component (140) that transmits the control information (450) through emission of patterned interference data concurrently while other users are transmitting other data (420). A second device (300) receives the patterned interference data and the other data via a single antenna (350) and decodes the patterned interference data to extract the control data (450). The first device (100) transmits the other data (420) on a side channel (440) that resides in the same spectrum as the main channel (410) in which the other data (420) is emitted. The first device (100) encodes the interference patterns such that the control data (450) can be safely transmitted and extracted without effecting other data transmission. In one aspect, devices (100, 200, 300) can employ a dynamic cooperation multi-access channel (DC-MAC) protocol (1510) to schedule transmission of the other data (420) on the main channel (410), and to employ the side channel (440) for control and coordination.
    • 描述了使用专门设计的干扰模式来构建带内侧信道而不降低主信道的有效吞吐量的系统,方法和装置。 第一设备(100)包括产生控制信息的控制组件(130)和通过在其他用户正在发送其他数据的同时发射图案化干扰数据来发送控制信息(450)的干扰组件(140)(420)。 第二设备(300)经由单个天线(350)接收图案化的干扰数据和其它数据,并解码图案化的干扰数据以提取控制数据(450)。 第一设备(100)在与发送其他数据(420)的主信道(410)在同一频谱中的侧信道(440)上发送其他数据(420)。 第一设备(100)对干扰图案进行编码,使得可以安全地传输和提取控制数据(450)而不影响其他数据传输。 在一个方面,设备(100,200,300)可以采用动态协作多接入信道(DC-MAC)协议(1510)来调度主信道(410)上的其他数据(420)的传输,并且 使用侧信道(440)进行控制和协调。
