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). Radio signals with given separate features and with given time delays between radio signals, which provide ordered arrival of radio signals at a RO, which is located at any point of the service area and known at the RO, are transmitted in series from N≥5 seriously numbered radio signal transmitting stations of a ground radio signal transmitting system, coordinates of phase centres of antennae of which are known at the RO, and the reception time of said signals is recorded in a time reference system specified at the RO. At the RO, coordinates of the phase centre of the antenna of the RO are measured according to proposed measurement equations based on said coordinates and reception time of identified corresponding stations of the ground radio signal transmitting system in a series, based on said given time delays between radio signals.

EFFECT: high efficiency and simplification of corresponding radio systems.
