  • Scheduling apparatus and method of relay-based network
    Patent number: 8565144
    Abstract: Disclosed are a scheduling method and apparatus for a relay-based network. The scheduling apparatus may assign a plurality of sub channels to links, with respect to each of a first sub frame and a second sub frame included in s downlink sub frame. The scheduling apparatus may perform scheduling in cases where nodes operated as transmitters and as receivers in the first sub frame and the second sub frame may diversely exist.
    Type: Grant
    Filed: September 27, 2009
    Date of Patent: October 22, 2013
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Young-Doo Kim, Mohamed Rashad Salem, Abdulkareem Adinoyi, Halim Yanikomeroglu, David Falconer
  • Apparatus and method for allocating subchannels and controlling interference in OFDMA systems
    Patent number: 8339975
    Abstract: Provided is an apparatus for controlling interference. The apparatus may receive interference information about at least one subchannel which is allocated to at least one node in an OFDMA system. The apparatus may create an interference list using the interference information. The apparatus may report the interference list to a radio network controller (RNC).

  • APPARATUS AND METHOD FOR ALLOCATING SUBCHANNELS AND CONTROLLING INTERFERENCE IN OFDMA SYSTEMS
    Publication number: 20090310478
    Abstract: An apparatus for allocating subchannels is provided. The apparatus includes: a subchannel allocation coefficient determination unit determining a subchannel allocation coefficient using a queue length of at least one terminal and a signal to interference plus noise ratio (SINR) of the at least one terminal and at least one relay station in an Orthogonal Frequency Division Multiple Access (OFDMA) system; and a subchannel allocation unit allocating a subchannel to at least one link formed in the OFDMA system using the subchannel allocation coefficient.
