A method performed by a mobile lawn mowing robot includes pairing a beacon with the mobile lawn mowing robot. Pairing the beacon with the mobile lawn mowing robot includes determining a distance between the beacon and the mobile lawn mowing robot and confirming that the beacon is within a pairing distance from the mobile lawn mowing robot based on a comparison of the determined distance to a pairing distance. Pairing the beacon with the mobile robot lawn mowing robot further includes, subsequent to confirming that the beacon is within the pairing distance from the mobile lawn mowing robot, pairing the beacon with the mobile lawn mowing robot, and, following pairing, detecting wideband or ultra-wideband signals from the beacon, and using the wideband or ultra-wideband signals to enable navigation over an area.

The present application relates to correction of position data used in a position information collection system, in which measurement points correspond to position data of a mobile body at respective time points and a movement path of the mobile body connects the measurement points in a time series. When the position data produces a movement path of the mobile body which passes through a not-enterable area, the position data is corrected such that the movement path of the mobile body circumvents the not-enterable area without reducing positioning accuracy, by performing position correction operations which include: determining a crossing status with regard to how the movement path crosses the not-enterable area; counting a number of the measurement points within the not-enterable area; and correcting the position data such that the movement path circumvents the not-enterable area.

This application relates to the field of communications technologies. A method includes: A first device receives first configuration information sent by a second device. The first configuration information includes at least one of information about a reference signal, frequency range information of a radio frequency signal, or bandwidth range information. The first device measures a first reference signal set, to obtain a first measured value. The first reference signal set includes at least two reference signals. The first device determines an expansion factor α based on the first configuration information. The first device determines a second measured value based on the first measured value and the expansion factor α.

A position determination device determines the position of a terminal. A signal of a sensor attached to one or both of a beacon and a terminal is sampled, so that a signal of the beacon may be transmitted and received only when the beacon or the terminal has moved. A plurality of beacons sequentially transmit beacon signals to determine the terminal position by determining a distance between the respective beacons and the terminal based on a time to receive the beacons. The device includes a beacon for transmitting a beacon signal; a terminal for receiving the beacon signal; and a first sensor attached to the terminal to sense movement of the terminal and to output a first sensing signal indicative of the sensed movement. The terminal has a reception mode for receiving the beacon signal and turns on/off the reception mode based on the first sensing signal.
