摘要： A wireless spectrum is shared between a primary communication system and secondary communication system operating in an overlapping geographical region. A primary transmitter broadcasts a primary signal, and a secondary transmitter transmits a secondary signal, both using a primary wireless spectrum assigned to the primary communication system. The secondary transmitter transmits the secondary signal to a secondary receiver with power (1-a)P and transmits the primary signal with power aP. The parameter a is computed to ensure a predetermined quality of reception of the primary signal by a hypothetical primary receiver located near the secondary transmitter. The secondary transmitter may compute a feasibility of using cognitive transmission and, when the computed feasibility exceeds or does not exceed a feasibility threshold, it selects to enable or disable, respectively, the use of the primary wireless spectrum to transmit from the secondary transmitter.

摘要： The proposed layer solution defines two or more layers of relay nodes (10) to convey traffic data from a source node (10S) to a destination node (10D). All of the nodes (10) in a given layer were selected for that layer because they each satisfied a signal quality requirement specified for that layer, where all relay nodes (10) defined in one layer simultaneously start transmitting in response to a received transmission. Due to the layered approach, the destination node (10D) may be configured to decode only the traffic data relayed by the relay nodes (10) in the immediately preceding (final) layer while treating any remaining received signals as noise. As a result, only those relay nodes (10) most likely to significantly contribute to and improve the signal quality of traffic data received at the destination node (10D) are selected as relay nodes (10) for a particular source-destination node pair.
摘要翻译：所提出的层解决方案定义了两层或更多层中继节点（10）以将业务数据从源节点（10S）传送到目的节点（10D）。给定层中的所有节点（10）都被选择用于该层，因为它们各自满足为该层指定的信号质量要求，其中在一个层中定义的所有中继节点（10）响应于接收到的传输而同时开始传输。由于分层方法，目的地节点（10D）可以被配置为仅解码紧接在前面（最后）层中的中继节点（10）中继的业务数据，同时将任何剩余的接收信号作为噪声处理。结果，只有那些最有可能对在目的地节点（10D）处接收到的业务数据的信号质量作出显着贡献并且提高其信号质量的中继节点（10）被选择为用于特定的源 - 目的地节点对的中继节点（10）。
