The invention relates to communications, and more particularly to a method of transmitting radio signals ground points of the transmitting radio signals by the system and receive radio signals to and retrieve information in the information system, located at the receiving radio signals radio object, stationary or movable. Such systems include, in particular, radio navigation and radar systems, radio, radio equipment, radio results the surface of the Earth and other [Radio system / Y. M. Kazarinov and others, edited by Y. M. Kazarinov. - M: CI "Academy", 2008, page 7]. Radio signals transmit sinhronizovano ground points of the transmitting radio signals by the system, the phase centers of the transmitting antennas of each of the orderly numbered transmitting the radio signal points of which at least five are given points with coordinates known and the receiving radio signals radio object. Implementation options including to measure the spatial coordinates of the receiving radio signals of radio objects, to facilitate the appropriate extraction system information, to increase their technical and economic efficiency, taking into account all components affecting the cost and technical performance.

Known methods of transmission and reception of R is of biosignals and retrieve information in the information system, used in particular for measuring the coordinates of radio objects based on the use of angular, rangefinder, differential and total-ranging and combined methods of determining the location of the object with the amplitude, time, frequency, phase and pulse-phase methods of measurement of parameters of radio patents of the Russian Federation№№2018855, 2115137, 2258242, 2264598, 2309420, 2325666, 2363117, 2371737, 2378660; the Basics of testing aircraft / E.

Methods of evaluating the effectiveness of the positioning of the radiation sources. - M.: radio engineering, 2008, mainly 5]. The known methods have various disadvantages, such as the need for mechanical movement of the antenna system, the inability to uniquely determine the coordinates of the object, the need for a priori information about the location of the object, the need for common synchronization of transmitting and receiving radio signals of radio objects, lack of reliability. According to the criterion of minimal sufficiency, the closest one is the method of transmitting and receiving radio signals to and retrieve information in the information system under the patent RU№2453999.

The advantage of the proposed method of transmitting and receiving radio signals to and retrieve information in the information system in comparison with the known is the possibility of increasing the technical and economic efficiency of radio systems measurement of spatial coordinates and other characteristics of an object that are functionally associated with its coordinates, including ensuring the accuracy and reliability of their measurement in accordance with modern requirements. This is achieved in that, in particular, does not require total synchronization of the combined transmitting and receiving radio signals of radio objects. This simplifies the determination of the spatial coordinates. Spatial coordinates are determined by indirect measurement using simple expressions that depend on the measured moments of the time of reception of radio signals to the receiving radio signals of the radio object. The method eliminates the ambiguity of measurement of coordinates.

Optionally transmit radio signals with predetermined, obazatelno the same, and known to the receiving radio signals of radio objects with time delays between the signals.

Radio signals take on a specific receiving radio signals radio object and identify their respective transmitting radio signals. This object register the moments of the times of reception of radio signals in a given it system timing. If necessary, exclude from them the corresponding specified time delay. These moments of times of reception of radio signals from an excluded at times delays if necessary center through exceptions each time the average value of all points of the time series. On the basis of the thus registered moments of time tnmeasure the parameters of the dnwith the dimension of length dn=υtnwhere υ is the velocity of propagation of the radio signal. In the information system of the receiving radio signals of radio object through the measured parameters dnand the above-mentioned Xn, Yn, Znmeasure the parameters ciwhere the index i varies from 1 to 6, in accordance with the measurement equations (1).

SUBSTANCE: invention relates to a method and a system for non-periodic feedback in carrier aggregation conditions. The method contains the following steps: a base station sends a non-periodic initiating signal to a separate piece of the user equipment (UE). The latter receives that signal and determines the component carrier of a downlink (DL CC) that requires feedback, according to the non-periodic initiating signal. Then the UE initiates a non-periodic feedback for the selected DL CC, maintaining the correspondence between DL CC and a component carrier of the upperlink (UL CC). The stage of determining the DL CC requiring feedback contains the following steps: UE defines the first UL CC in accordance with the scheduling information, containing the non-periodic initiating signal, searches for DL CC, to which the first UL CC corresponds, as per the saved correspondence between DL CC and UL CC. Then it defines the found DL CC as the one requiring feedback.

EFFECT: effective decrease of the feedback traffic along the upperlink.

SUBSTANCE: invention can be used to determine spatial coordinates of a stationary or mobile radio signal receiving radio facility (RO). A radio system (RS) comprises a ground radio signal transmitting system with N≥5 radio signal transmitting stations, coordinates of phase centres of antennae of which are known at the RO. The transmitting stations are configured for synchronised ordered transmission of radio signals in series, with given separate features and with given time delays between radio signals, which provide ordered arrival of radio signals at the RO, located at any point in a service area. Each RO comprises a radio signal receiving device configured to receive and identify radio signals of the corresponding transmitting station, a recorder for recording the reception time thereof in a time reference system specified at the RO and an information system configured, based on said coordinates and reception time of radio signals in the series, taking into account said time delays between radio signals, to measure coordinates of phase centres of the antenna of the RO according to the proposed measurement equations.

EFFECT: higher efficiency and simplification of corresponding radio systems.
