Abstract: Disclosed is a communication method using outdated channel state information in a network environment having a G-cell and 2-user terminal, by allowing a terminal and base stations to transmit and receive data symbols for G time slots, and to transmit and receive a reconfiguration signal for an additional one time slot.

Abstract: Disclosed is a communication method of a terminal utilizing outdated channel information in a two-cell, three-user network environment, the method comprising: transmitting nine different first linear combinations to a first base station in each time slot during a first time interval; receiving a first feedback signal from a second base station which has received the first linear combination as an interference signal; transmitting four different second linear combinations to the first base station during a first sub-time interval of a third time interval; receiving a second feedback signal from the second base station which has received the second linear combinations as an interference signal; and transmitting reconfiguration signals consisting of eight data symbols to the first base station during a third sub-time interval of the third time interval. Further, a communication method of a base station corresponding to such a terminal is also disclosed.
