    • Mobile communication system equipment avoids interfering with another transmitter's operation. Sensing information indicating whether the other transmitter's signal has been detected is received from remote sensors, wherein each of the remote sensors is situated at a respective one of two or more sensor locations. The sensing information and information about the sensor locations is used to ascertain one or more exclusion boundaries needed to avoid interfering with the other transmitter's use of the spectral resource. Beamforming parameters are ascertained that will enable the main node to transmit within one or more predefined geographical areas except for any portion of a predefined area located on a far side of the one or more exclusion boundaries. Two or more adjusted signals are produced as a function of the beamforming parameters and one or more signals to be transmitted. The adjusted signals are transmitted from respective ones of two or more antennas.

    • User equipment comprising a receiver obtains information about a set of channels to be sensed in a sensing process, wherein each channel is associated with a respective one of a number of radio frequencies. The receiver obtains a radio frequency signal by simultaneously sensing two or more of the channels included in the set of channels. A total power level of the sensed two or more channels is measured, and a comparison result is generated by comparing the total power level of the sensed two or more channels with a predetermined power level. The user equipment is controlled based on the comparison result. For example, if the total power level is below a threshold, then the sensed channels can be considered to not be in use by external transmission equipment.
    • 包括接收器的用户设备在感测过程中获得关于要感测的一组信道的信息,其中每个信道与多个无线电频率中的相应一个相关联。 接收机通过同时感测包括在该组信道中的两个或多个信道来获得射频信号。 测量感测的两个或更多个通道的总功率电平,并且通过将所感测的两个或更多个信道的总功率电平与预定功率电平进行比较来生成比较结果。 基于比较结果控制用户设备。 例如,如果总功率水平低于阈值,则感测到的通道可被认为不被外部传输设备使用。

    • According to one aspect of the teachings presented in this document, a wireless communication receiver implements a form of joint detection that is referred to as “fast joint detection” (FJD). A receiver that is specially adapted to carry out FJD processing provides an advantageous approach to joint detection processing wherein the number of computations needed to produce reliable soft bits, for subsequent turbo decoding and/or other processing, is significantly reduced. Further, the algorithms used in the implementation of FJD processing are particularly well suited for parallelization in dedicated signal processing hardware. Thus, while FJD processing is well implemented via programmable digital processors, it also suits applications where high-speed, dedicated signal processing hardware is needed or desired.
    • 根据本文献中提出的教导的一个方面,无线通信接收机实现被称为“快速关节检测”(FJD)的联合检测形式。 专门用于执行FJD处理的接收机提供了联合检测处理的有利方法,其中显着地减少了用于后续turbo解码和/或其他处理产生可靠软比特所需的计算次数。 此外,在执行FJD处理中使用的算法特别适用于专用信号处理硬件中的并行化。 因此,虽然FJD处理通过可编程数字处理器很好地实现,但它也适用于需要或期望高速,专用信号处理硬件的应用。
