摘要： A method of wireless communication in white space includes spectrum sensing in the white space during each of multiple sensing intervals. The method also includes determining whether each of the sensing intervals is subject to bursty interference. The determining process may be based on a time domain analysis or a frequency domain analysis of signal power during each sensing interval.

摘要： White space signals are differentiated from licensed ATSC signals through modification of a waveform of the white space signal. White space signals may be modified by shifting the ATSC-compatible waveform so that the pilot frequency of the white space signal is at a location outside of the frequency range associated with the pilot frequency in a licensed ATSC signal or embedding a watermark signal into said ATSC-like white space signals. White space device transmitters generate the signals with these modifications and white space receivers are equipped to detect whether a pilot exists in the standard licensed pilot frequencies. Based on these differences, white space devices can better operate without interfering with licensed ATSC transmission. Additionally, the modification techniques may be used to embed data in the white space signal that may be used to communicate connection data or networking data to other white space devices.
摘要翻译：通过修改白空间信号的波形，白色空间信号与许可的ATSC信号区分开来。可以通过移动ATSC兼容波形来修改白色空间信号，使得白色空间信号的导频位于与授权的ATSC信号中与导频频率相关联的频率范围之外的位置，或者将水印信号嵌入到所述ATSC 像空白信号。白色空间设备发射机通过这些修改产生信号，并配备白空间接收机，以检测在标准许可的导频中是否存在导频。基于这些差异，白色空间设备可以更好地操作而不干扰授权的ATSC传输。此外，修改技术可以用于将数据嵌入到可用于将连接数据或联网数据传送到其他空白设备的空白信号中。

摘要： A decentralized approach to peer discovery channel selection is used in some embodiments. In some such embodiments, a mobile wireless terminal supporting a peer to peer signaling protocol, independently determines what channels to use for peer discovery without a central controller indicating the channel or channels to be used. Assuming channels are of a suitable quality, the channels having the best quality need not be identified, with channel selection being made on a predetermined channel ordering basis from those with suitable quality. Different wireless communications devices in the system use the same peer discovery channel selection process making it likely that the same channel or channels will tend to be picked to be used for peer discovery. Other embodiments are directed to implementing a centralized approach to peer discovery channel selection in which a central controller or base station selects channels to be used for peer discovery signaling.
摘要翻译：在一些实施例中使用分布式对等体发现信道选择方法。在一些这样的实施例中，支持对等信令协议的移动无线终端独立地确定用于对等体发现的哪些信道，而不指示要使用的信道或信道的中央控制器。假设信道具有合适的质量，则不需要识别具有最佳质量的信道，其中信道选择是从具有适当质量的信道选择进行的。系统中的不同的无线通信设备使用相同的对等体发现信道选择过程，使得可能相同的信道或信道将倾向于被选择用于对等体发现。其他实施例涉及实现对等体发现信道选择的集中式方法，其中中央控制器或基站选择要用于对等体发现信令的信道。

摘要： Apparatus and method for spectrum sharing using listen before talk (LBT) and quiet periods are disclosed. This includes assessing using LBT to determine if a shared spectrum channel is being used by at least one other network, and transmitting transmission frames over the shared spectrum channel in at least one of an uplink or a downlink when the channel is determined as not being used. The accumulated time of transmission use of the spectrum channel is counted based on predetermined conditions, and a determination made when the accumulated time exceeds a maximum allotted time. Transmission of frames by a network is allowed to continue if the maximum time has not been exceeded and the spectrum remains available. A quiet period is then executed once the maximum time period is exceeded.

摘要： A user equipment (UE) may detect a potential collision between a discontinuous reception (DRX) pattern of a first radio access technology (RAT) and a reception time of a message from a second RAT of a remote device. The reception time may be unknown. The UE may dynamically reconfigure the DRX pattern to reduce a likelihood of the potential collision. The UE may also configure transmission of a different message by the second RAT during a DRX off-period to reduce a likelihood of the potential collision.

摘要： There lies a challenge to develop a technique of accurately and efficiently determining an available communication channel. In accordance with some embodiments disclosed herein, techniques for sensing a primary user of a particular communication channel are performed more efficiently. In some implementations, a geo-location of a communication device is combined with a sensing algorithm in order to more efficiently perform spectrum sensing. In some implementations, a geo-location and an accuracy determination may be used to determine all required sample regions in order to ensure that a primary user is not present in a particular location.

摘要： In a multi-radio device, a configurable filter may be placed on the transmit side of an aggressor radio to reduce interference to receive side performance of a victim radio. The filter may be adaptively configured based on performance of the victim radio. The configurable filter may be in the form of a notch filter. The depth and width of the notch filter may be configured. The filter may be used to create a virtual guard band between an Industrial Scientific and Medical (ISM) band and a cellular band by puncturing a physical uplink control channel (PUCCH) transmission nearest to the ISM band or reducing power on the nearest PUCCH transmission.
