  • Data transmission and reception method and apparatus for use in MIMO system
    Patent number: 10103791
    Abstract: A data transmission and reception method and apparatus in a Multiple-Input Multiple-Output (MIMO) system. The transmission method includes selecting at least one antenna for use in transmission among a plurality of antennas based on transmission data and transmitting the transmission data through the selected antenna. The data transmission and reception method and apparatus are advantageous in increasing the throughput of the MIMO communication system. Also, the data transmission and reception method and apparatus are capable of making it possible to design a superior transceiver in complexity and performance. Also, the data transmission and reception method and apparatus are capable of acquiring extra Degree of Freedom (DOF) and thus increasing the number of symbols that can be transmitted at a time. Furthermore, the data transmission and reception method and apparatus are applicable to conventional MIMO communication systems to obtain extra performance gain without being restricted to certain conditions.

  • Inter-cell interference coordination method and apparatus for use in mobile communication system
    Patent number: 9414328
    Abstract: A data transmission and/or reception method of a base station in a wireless communication system is provided. The data transmission/reception method includes receiving information on interference measured by a terminal, allocating a downlink resource to a terminal based on the received interference information, determining per-subband transmit power distributions of the downlink resource allocation, and transmitting the per-subband transmit power distributions of the downlink resource allocation to neighbor base stations.
