Abstract: Methods and devices for determining a relative position between a first device and a second device are described. Measurement signals are transmitted from the first device to the second device. Each measurement signal is associated with a corresponding radio frequency spectrum in which the measurement signal is transmitted. A first radio frequency spectrum associated with a first measurement signal has a different frequency range than a second radio frequency spectrum associated with a second measurement signal of the plurality of measurement signals. At the second device the relative position based on at least the first and second measurement signals is determined.

Abstract: The present invention relates to a method for determining a relative position between a first device and a second device. A plurality of measurement signals is transmitted from the first device to the second device. Each measurement signal of the plurality of measurement signals is associated with a corresponding radio frequency spectrum in which the measurement signal is transmitted. A first radio frequency spectrum associated with a first measurement signal has a different frequency range than a second radio frequency spectrum associated with a second measurement signal of the plurality of measurement signals. At the second device the relative position based on at least the first and second measurement signals is determined.
Abstract translation: 本发明涉及一种用于确定第一设备和第二设备之间的相对位置的方法。 多个测量信号从第一设备发送到第二设备。 多个测量信号中的每个测量信号与发送测量信号的对应的射频频谱相关联。 与第一测量信号相关联的第一射频频谱与与多个测量信号的第二测量信号相关联的第二无线电频谱具有不同的频率范围。 在第二装置处，确定至少基于第一和第二测量信号的相对位置。

Abstract: A method, in a first subset of a sequence of transmission intervals, including communicating, on a radio link of a cellular network and according to a resource mapping, pilot signals having a non-zero first transmit power. The method includes, in a second subset of the sequence of transmission intervals, communicating, on the radio link and according to the resource mapping, the pilot signals having a non-zero second transmit power which is larger than the first transmit power.

Abstract: The present invention relates to a method for operating a wireless communication system. The wireless communication system comprises a base station and a terminal. The terminal comprises a plurality of antenna elements and provides at least two antenna array configurations comprising a first antenna array configuration comprising at least two antenna elements having same radio transmission characteristics and a second antenna array configuration comprising at least two antenna elements having different radio transmission characteristics. According to the method, a selection process for selecting and an antenna array configuration of the at least two antenna array configurations is triggered and for each of the at least two antenna array configurations a corresponding figure of merit is determined. The corresponding figure of merit is determined based on corresponding pilot signals received from the base station via the corresponding antenna array configuration. Depending on the figures of merit, an antenna array configuration is activated.
