Abstract: Various embodiments relate to wireless communications, and more particularly, to methods and apparatus for authorizing use of spectrum, e.g., through the issuance of spectrum access keys, and/or preventing or discouraging the unauthorized use of licensed spectrum. Peer to peer wireless communications between authorized users of licensed spectrum may involve scrambling/descrambling of information communicated between authorized devices. In some embodiments air interface timing and/or other information received from a second device, e.g., a beacon or GPS transmitter, is incorporated into a computation of a pseudo-random bit sequence which is also computed based on a spectrum access key communicated to authorized spectrum users. In some embodiments authorized peer to peer devices scramble communicated information based on the generated pseudo random bit sequence thereby preventing or discouraging communication with devices which are not authorized to use the spectrum and lack a spectrum access key used to generate the pseudo random bit sequence.

Abstract translation: 各种实施例涉及无线通信，更具体地，涉及用于授权使用频谱的方法和装置，例如通过发布频谱接入密钥，和/或防止或阻止未授权使用许可频谱。 许可频谱的授权用户之间的对等无线通信可能涉及在授权设备之间传送的信息的加扰/解扰。 在一些实施例中，从第二设备（例如，信标或GPS发射机）接收的空中接口定时和/或其他信息被并入到伪随机比特序列的计算中，所述伪随机比特序列也是基于传送给授权的频谱接入密钥 频谱用户。 在一些实施例中，授权的对等设备基于生成的伪随机比特序列来加扰传送的信息，从而防止或阻止与未被授权使用频谱的设备的通信，并且缺少用于生成伪随机比特序列的频谱接入密钥。
