  • Method and system for providing channel state information feedback in a wireless communication system
    Patent number: 8611259
    Abstract: A method of providing channel state information feedback in a wireless communication system is provided. The method includes measuring original channel state information for each of a plurality of channels. An offset vector is applied to the original channel state information to generate modified channel state information. A subset of the channels is identified based on the modified channel state information. The original channel state information or the modified channel state information is reported.
    Type: Grant
    Filed: June 1, 2007
    Date of Patent: December 17, 2013
    Assignee: Samsung Electronics Co., Ltd.

  • Transmission methods for downlink ACK/NACK channels
    Patent number: 8599954
    Abstract: A method from transmitting data via multiple antennas. In this method, four information bits to be transmitted are multiplexed by using either one of a code division multiplexing scheme or a second code division multiplexing scheme combined with a real and imaginary multiplexing scheme, to generate a code division multiplexed symbol including four vectors. Then, the code division multiplexed symbol is repeatedly transmitted by alternatively applying two transmit diversity schemes via four transmission antennas.
