摘要： 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.

摘要： A radio communication device applies a beamforming pattern defining plurality of beams (411, 412, 413, 414, 415, 416, 417). From the plurality of beams (411, 412, 413, 414, 415, 416, 417), the radio communication device selects at least one main beam (412) and a set of auxiliary beams (411, 413). Exclusively on the at least one main beam (412), the radio communication device sends radio transmissions to a further radio communication device (420). Further, the radio communication device monitors signals transmitted by the further communication device (420) on the at least one main beam (412) and the set of auxiliary beams (411, 413). Depending on the monitored signals, the communication device reselects at least one beam from the set of auxiliary beams as the at least one main beam.

摘要： Beam sweep configuration (4001, 4002) of at least one beam sweep (391-394) is exchanged between nodes (101, 102) of a network. The beam sweep configuration may be indicative of a time-duplex configuration of a plurality of beams of the at least one beam sweep (391-394).

摘要： A first terminal receives, on a radio link of a cellular network, at least one uplink pilot signal transmitted by at least one second terminal. The first terminal transmits, on the radio link and to an access node of the cellular network, an uplink report message indicative of at least one property of the received at least one uplink pilot signal.

摘要： 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.
