    摘要： A positioning measurement method and an apparatus therefor, which are applied to systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, and a 5G new radio (NR) system. The method comprises: receiving first indication information of a network device, the first indication information comprising at least one positioning state number; and determining a positioning configuration corresponding to the at least one positioning state number, and performing positioning measurement and reporting according to the positioning configuration. The positioning state configuration corresponding to the corresponding positioning state number is obtained by means of the first indication information, and the positioning state configuration is integrated and corresponds to the positioning state number, thereby helping to reduce report delay and preventing positioning delay.

    摘要： A system and a relative method for determining the north/south, east/west and up/down components (1) of the displacement of persistent scatterers (21) comprising an arithmetic device that is configured to execute: processing of importing displacement time series data (2) derived from multi-temporal of satellite SAR data over the persistent scatterers; processing of importing the geographical coordinates data of the persistent scatterers, information data about the persistent scatterers, orbit type data about the persistent scatterers, orbit parameters data about the persistent scatterers; calculating, for each scatterer, a total displacement value (30); grouping (9) the scatterers in a plurality of clusters based on the geographical coordinates; calculating a quantity dependent on the displacement time series for each scatterer; classifying the scatterers based on the orbit type; grouping (10) the ascending/ descending scatterers in a plurality of ascending/ descending subclusters based on the quantity value; calculating a geometrical distance between the centroid of each ascending subcluster and the centroid of each descending subcluster, thus obtaining a set of geometrical distance values for each subclusters; classifying the subclusters based on the set of geometrical distance values in isolated and coupled subcluster, depending on all values of the set of geometrical distance values are below or above a fixed threshold; identifying (11), for each coupled ascending subcluster, the descending subcluster having the minimum geometrical distance from the coupled descending subcluster, thus defining a couple of two associated subclusters; calculating, for each coupled subcluster, an average total displacement and an average incidence angle, calculating (12) the north/south, east/west and up/down components (1) of each scatterer of each subcluster using information from the subcluster of the opposite type if the subcluster is coupled.

    摘要： This application provides an imaging method and apparatus, which may be applied to the field of imaging technologies, to implement high-quality imaging at high resolution. The method includes: transmitting a first signal at a first moment, transmitting a second signal at a second moment, and receiving a third signal and a fourth signal, to determine imaging of a first object based on the third signal and the fourth signal. The first moment is different from the second moment. A frequency and/or a transmission location of the first signal are/is different from that of the second signal. The third signal is a signal obtained by using the first signal via the first object. The fourth signal is a signal obtained by using the second signal via the first object.
