  • Patent number: 10149170
    Abstract: A method and an apparatus for controlling an adaptive flow in a wireless communication system is provided. A method of a master base station in a wireless communication system, in which base stations having different cell sizes coexist, comprises the steps of: receiving load information from at least one other base station, receiving channel information about the at least one other base station from a terminal connected to the master base station, determining a secondary base station capable of load sharing for the terminal on basis of the channel information and the load information, and requesting, from the terminal, a further connection to the secondary base station. Offloading for downlink transmission of the terminal is determined based on the load information of a small cell. Furthermore, a resource distribution ratio for downlink transmission of the terminal is determined based on channel quality information reported from the terminal.

  • Patent number: 9655023
    Abstract: Provided is a method for operating a co-site by a Base Station (BS) in a mobile communication system. The method includes determining a first number of Mobile Stations (MSs) among MSs connected to a cell to perform handover to a co-site using an Air Resource (AR) utilization of the cell that uses a first Frequency Reuse Pattern (FRP) and an AR utilization of the co-site that uses a second FRP, or determining a second number of MSs among MSs connected to the co-site to perform handover to the cell; and sending a handover initiation message to the MSs according to the determinations.

  • Patent number: 8953534
    Abstract: A method for avoiding interference of an interfering Base Station (BS) in an interfered BS of a mobile communication system includes determining an interference value of an interfering BS at a control region during a determination interval. When the interference value is greater than a threshold value, the method further includes operating in a modified Transmit/receive Transition Gap (TTG) mode. When the interference value is less than the threshold value, the method further includes operating in a general TTG mode.

  • Patent number: 8229435
    Abstract: A base station is capable of performing a method for scheduling in a wireless communication system. In the method, a downlink channel measurement value received from a terminal is compared with a threshold. When the downlink channel measurement value is smaller than the threshold, an activation set for a handover of the terminal is determined. When the number of base stations inside the activation set is two or more, a Modulation and Coding Scheme (MCS) level is allocated to the terminal with consideration of the downlink channel measurement value. A wireless resource is allocated to the terminal with consideration of the allocated MCS level and a headroom of the terminal.

  • Patent number: 7778217
    Abstract: An uplink scheduling system and method in a wireless broadband internet communication system includes calculating priorities of mobile stations (MSs) taking into account headroom size indicating transmission power additionally available for each of the MSs; and determining a transmission format of an MS selected to be preferentially allocated a slot as a result of the priority calculation, taking into account headroom size reported by the selected MS and a margin determined depending on a variation in channel state between the selected MS and a base station (BS).
