    • A method, a computer program product, and an apparatus for wireless communication are provided. The apparatus transmits a first peer discovery signal with a first periodicity/temporal frequency in a first set of peer discovery resources. The apparatus determines an energy on an allocated peer discovery resource of a second set of peer discovery resources. The apparatus refrains from transmitting a second peer discovery signal in the second set of peer discovery resources when the energy is greater than a threshold. The apparatus transmits the second peer discovery signal in the second set of peer discovery resources with a second periodicity/temporal frequency less than the first periodicity/temporal frequency when the energy is less than the threshold. The apparatus may utilize the first set of peer discovery resources every period and the second set of peer discovery resources once every N periods in which once every N periods is the second periodicity.
    • 提供了一种方法,计算机程序产品和用于无线通信的装置。 该设备在第一组对等体发现资源中发送具有第一周期/时间频率的第一对等体发现信号。 设备确定第二组对等体发现资源的分配的对等体发现资源上的能量。 当能量大于阈值时,该装置禁止在第二组对等体发现资源中发送第二对等体发现信号。 当能量小于阈值时,该设备以第二周期/时间频率小于第一周期/时间频率,在第二组对等体发现资源中发送第二对等体发现信号。 该装置可以每N个周期每周期利用第一组对等体发现资源和第二组对等体发现资源,其中每N个周期中的一个是第二周期。

    • A detection system (100) and a method (300) for detecting the location of a target (101) are provided. The detection system (100) comprises a transmitter (102) for transmitting a probing signal (103) and a plurality of receivers (104) for receiving a first plurality of signals (105). A spatial compression entity (110) is provided for compressing the first plurality of signals into a second plurality of signals (113) being smaller than the number of the first plurality of signals. Furthermore, a temporal compression entity (120) is provided for compressing, at a frequency lower than the Nyquist frequency, the second plurality of signals into a plurality of signal data sets (122). The processing unit (123) is configured to estimate the location of the target based on the plurality of signal data sets. The detection system of the present invention may e.g. be part of a lighting control system for controlling the lighting.
    • 提供了一种用于检测目标(101)的位置的检测系统(100)和方法(300)。 检测系统(100)包括用于发送探测信号(103)的发射机(102)和用于接收第一多个信号(105)的多个接收机(104)。 空间压缩实体(110)被提供用于将第一多个信号压缩成小于第一多个信号的数量的第二多个信号(113)。 此外,提供了时间压缩实体(120),用于将第二多个信号的频率以低于奈奎斯特频率的频率压缩成多个信号数据集(122)。 处理单元(123)被配置为基于多个信号数据集来估计目标的位置。 本发明的检测系统可以是例如, 成为控制照明的照明控制系统的一部分。
