    摘要： A method and a device for adjusting downlink power in a wireless communication system are disclosed. A method for receiving control information according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, first configuration information related to a serving cell and second configuration information related to a CSI-RS resource, the first configuration information including information on energy per resource element (EPRE) of a secondary synchronization signal (SSS), the second configuration information including information on a first power offset of EPRE of the CSI-RS resource against the EPRE of the SSS; and receiving control information for adjustment of downlink transmission power from the base station. The control information may include an index of a CSI-RS resource related to the adjustment of the downlink transmission power.

    摘要： Embodiments of the present invention disclose a hierarchical network registration method. The method is applied to a hierarchical network formed by a terrestrial network and at least one layer of an air network, and the method includes: obtaining, by a radio network node, a registration result of an air network node, where the radio network node is located in the terrestrial network; the air network node is located in the air network, and covers the radio network node; and the registration result includes attribute information and beam information of the air network node; and broadcasting, by the radio network node, the registration result to a mobile user covered by the radio network node. The air network in the method of the present invention may be a satellite network, and the hierarchical network is a hierarchical network formed by the satellite network and the terrestrial radio network. The air network in the method of the present invention may be a balloon network, and the hierarchical network is a hierarchical network formed by the balloon network and the terrestrial radio network.
