A method for performing link adaptation, the method performed by a serving cell which performs interference randomization for inter-cell interference control and comprising: determining, by the serving cell, at least one coordination cell to which interference coordination is to be applied among neighbor cells; receiving, by the serving cell, information on a modulation level representing a modulation scheme of the at least one coordination cell; transmitting, by the serving cell, information on a protection space of the serving cell to the at least one coordination cell, wherein the information on the protection space of the serving cell includes information related to a resource, which is to be protected, and in which a modulation level limitation of the at least one coordination cell is required, and wherein the protection space is a space in which it is difficult to maintain a high interference plus noise ratio, SINR; receiving, by the serving cell, information on a modulation level limited interval of each of the at least one coordination cell, in which the modulation level for downlink transmission of the each of the at least one coordination cell is limited to be equal to or higher than a reference modulation level, from the at least one coordination cell; performing, by the serving cell, the link adaptation based on the infomation on the modulation level and the information on the modulation level limited interval of the each of the at least one coordination cell, wherein the modulation level has a value which increases as a modulation order increases, wherein the modulation level limited interval of the each of the at least one coordination cell is configured by the each of the at least one coordination cell to include the protection space of the serving cell or a part of the protection space of the serving cell, wherein at least one of the modulation level limited interval of the each of the at least one coordination cell, and the protection space of the serving cell is periodically updated at a second period, and wherein the information on the modulation level is periodically updated at a first period, and wherein the second period is larger than the first period. determining, by the serving cell, at least one coordination cell to which interference coordination is to be applied among neighbor cells; receiving, by the serving cell, information on a modulation level representing a modulation scheme of the at least one coordination cell; transmitting, by the serving cell, information on a protection space of the serving cell to the at least one coordination cell, wherein the information on the protection space of the serving cell includes information related to a resource, which is to be protected, and in which a modulation level limitation of the at least one coordination cell is required, and wherein the protection space is a space in which it is difficult to maintain a high interference plus noise ratio, SINR; receiving, by the serving cell, information on a modulation level limited interval of each of the at least one coordination cell, in which the modulation level for downlink transmission of the each of the at least one coordination cell is limited to be equal to or higher than a reference modulation level, from the at least one coordination cell; performing, by the serving cell, the link adaptation based on the infomation on the modulation level and the information on the modulation level limited interval of the each of the at least one coordination cell, wherein the modulation level has a value which increases as a modulation order increases, wherein the modulation level limited interval of the each of the at least one coordination cell is configured by the each of the at least one coordination cell to include the protection space of the serving cell or a part of the protection space of the serving cell, wherein at least one of the modulation level limited interval of the each of the at least one coordination cell, and the protection space of the serving cell is periodically updated at a second period, and wherein the information on the modulation level is periodically updated at a first period, and wherein the second period is larger than the first period.
