  • Patent number: 11178573
    Abstract: Provided are apparatuses and methods of managing a load of a base station node in fifth generation (5G) networks. The method of a master base station for managing a load of a secondary base station may include establishing dual connectivity with the secondary base station, receiving a secondary base station status indication message from the secondary base station through an X2 interface, and determining whether to apply an action for reducing a load of the secondary base station based on a value of a secondary base station load information parameter included in the secondary base station status indication message.
    Type: Grant

  • Patent number: 10812230
    Abstract: Provided are technologies for data transmission and reception using an interworking interface between heterogeneous radio access network base stations, such as between NR and LTE, for a 5G non-standalone (NSA) network. A base station for controlling downlink data transmission may include a controller configured to setting up an X2 interface for transmitting the downlink data to a UE by interworking with another base station, a transmitter configured to transmit downlink use data information including information indicating whether to perform retransmission of an associated downlink data packet to another base station through the X2 interface, and a receiver configured to receive downlink data transfer status information from another base station through the X2 interface.

  • Patent number: 9241283
    Abstract: The present disclosure is related to reporting channel state information associated with a downlink channel in a wireless communication system. In particular, a method of transmitting the channel state information in user equipment may include extracting one or more reference vectors having a high correlation with a channel state information vector associated with a downlink, creating one or more compressed vectors by compressing the one or more reference vectors, and transmitting the one or more compressed vectors.
