Abstract: An apparatus and method for performing sequential scheduling in a multiple-input, multiple-output (MIMO) system is provided. The method includes the steps of: selecting a user which reports the greatest partial feedback information among a plurality of pieces of partial feedback information of all users in an initialization operation, and requesting channel feedback information to the selected user; and broadcasting the channel feedback information of the selected user to remaining unselected users upon receiving the channel feedback information from the selected user. Accordingly, a maximum capacity can be obtained by using only selective channel feedback information without having to feed back channel state information of all users.

Abstract: Provided is a method for power control in a two-way relay network. The power control method may maximize a minimum transmission rating and a synthesized transmission rating of the overall system when there are restrictions on the synthesized power of terminals and a repeater in the two-way relay network. The power control method may include determining a power ratio for allocating power to each terminal and a repeater for each subcarrier under restriction on synthesized power of the terminals and the repeater and determining power allocated for each subcarrier according to the determined power ratio.
