摘要： An apparatus and method are disclosed for generating a transmission connection identifier (CID) for a transmitter/receiver pair in a wireless network. The CID may be selected from or mapped to a hybrid CID space comprising a first set of orthogonal CIDs and a second set of non-orthogonal (random or pseudo-random) CIDs. When a transmitter device wants to initiate a peer-to-peer connection with a receiver device, the transmitter and receiver devices attempt to obtain a CID to identify their connection within a traffic channel in a shared frequency space. The first and/or second device attempt to select a CID from the first set of orthogonal CIDs. However, if a CID collision is detected, the first and second devices select their CID from the second set of non-orthogonal CIDs. The selected transmission CID may be used during a time slot or interval to facilitate communications between the first and second devices.
摘要翻译：公开了一种用于为无线网络中的发射机/接收机对生成传输连接标识符（CID）的设备和方法。可以从包括第一组正交CID和第二组非正交（随机或伪随机）CID的混合CID空间中选择或映射CID。当发射机设备想要发起与接收机设备的对等连接时，发射机和接收机设备试图获得CID以识别它们在共享频率空间中的业务信道内的连接。第一和/或第二设备试图从第一组正交CID中选择CID。然而，如果检测到CID冲突，则第一和第二设备从第二组非正交CID中选择它们的CID。选定的传输CID可以在时隙或间隔期间使用以促进第一和第二设备之间的通信。

摘要： One feature provides for establishing an ad hoc peer-to-peer network over an existing channel allocation for another network. To mitigate interference between multiple peer-to-peer devices, a plurality of receiver chains in a receiver device may be configured with beamforming coefficients so as to focus reception in the direction of an intended signal from a transmitter device while minimizing reception from other directions. Similarly, the receiver device may also use a plurality of antennas and a transmitter chain to beamform in the direction of the transmitter device, thereby focusing its transmission toward the transmitter device. The receiver device may also notify nearby devices that it is employing a plurality of receive antennas. This information can be used by the nearby devices to more intelligently perform transmitter yielding. By utilizing beamforming information to make the transmitter and/or receiver yielding decision, better interference mitigation may be achieved.
摘要翻译：一个特征提供了通过用于另一网络的现有信道分配来建立自组织对等网络。为了减轻多个对等设备之间的干扰，接收机设备中的多个接收器链可以被配置成具有波束成形系数，以便在来自发射机设备的预期信号的方向上聚焦接收，同时最小化从其他方向的接收。类似地，接收机设备还可以使用多个天线和发射机链在发射机设备的方向上波束成形，从而将其传输集中到发射机设备。接收机设备还可以通知附近的设备它正在采用多个接收天线。该信息可被附近的设备用于更智能地执行发射机的收发。通过利用波束成形信息来使发射机和/或接收机产生决定，可以实现更好的干扰减轻。

摘要： To mitigate interference between multiple peer-to-peer devices, transmitter yielding and/or receiver yielding may be performed among devices operating in a peer-to-peer network. Generally, a transmitter device will yield communications on a time slot to a higher priority transmitter device if it will cause unacceptable interference to a higher priority receiver device. Likewise, a receiver device may yield use of the time slot if interference is unacceptably high. Both transmitter and receiver yielding may be improved by use of beamforming at a receiver device. By utilizing beamforming information to make the transmitter and/or receiver yielding decisions, better interference mitigation may be achieved.
摘要翻译：为了减轻多个对等设备之间的干扰，可以在操作在对等网络中的设备之间执行发射机让步和/或接收机让步。通常，如果发射机设备将对较高优先级的接收机设备造成不可接受的干扰，则发射机设备将在时隙上向较高优先级的发射机设备进行通信。同样，如果干扰不可接受地高，接收机设备可以使用该时隙。通过在接收机设备上使用波束成形可以改善发射机和接收机的良率。通过利用波束形成信息来使发射机和/或接收机产生决定，可以实现更好的干扰抑制。
