A performance metric for a user equipment k can be defined as Equation 2 in the following using a PSTSR (potential signal to total signal ratio).
[0076] In Equation 2, P.sub.m corresponds to transmit power of a base station m, R.sub.mk.sup.−α corresponds to path loss between the base station m and the user equipment k and a.sub.mk corresponds to a resource allocation gain from the base station to the user equipment k.

allocating the gain to each of the plurality of transmission paths, based on a result of comparing the loss variance value with a second threshold value.
However, Ko teaches
generating a loss variance value by calculating a variance of the loss information of each of the plurality of transmission paths; ([0079] In Table 1, since x.sub.k corresponds to a value deducted from the constraint of Equation 3-2, the x.sub.k corresponds to a value related to performance of the user equipment k. Since y.sub.m corresponds to a value deducted from the constraint of Equation 3-3, the y.sub.m corresponds to a value related to load of the base station m. P.sub.m corresponds to transmit power of the base station m and R.sub.mk.sup.−α corresponds to a path loss between the base station m and the user equipment k. Hence, S.sub.mk indicates a signal strength depending on the path loss between the user equipment k and the base station m only.) and
allocating the gain to each of the plurality of transmission paths, based on a result of comparing the loss variance value with a second threshold value. ([0080] In Equation 4, if signal strength S.sub.mk depending on the path loss between the user equipment k and the base station m only is greater than a specific threshold value …. the base station m can be selected as a cluster base station of the user equipment. In Equation 4, a threshold value is determined by three variables w.sub.mk, x.sub.k, and y.sub.m.)

([0131] Modeling is performed on a channel between a base station and a user equipment in a manner of reflecting path loss and shadowing to the channel. In this case, each path loss follows a formula of 128.1+37.6×log.sub.10(d), d corresponds to a distance in km unit, and shadowing of a channel has dispersion of 8 dB. ExpRate(S) corresponds to a sum of data transfer rate expected from a base station cluster for each user equipment set when a zero forcing precoding scheme and an equal power allocation are applied.)

wherein the gain is allocated to each of the plurality of transmission paths, based on the gain allocation matrix and the precoding matrix, ([0158] If ν and λ satisfying three conditions of Table 3 are found, it might say a precoding vector at that time satisfies the KKT condition. In Table 3, a third condition operates based on two matrixes A.sub.k and B.sub.k. Each of the matrixes is explained. The matrix A.sub.k is configured based on a channel heading to a user equipment k from cluster base stations of the user equipment k and reflects a signal component. The matrix B.sub.k is configured based on a channel heading to other user equipments except the user equipment k and reflects an interference component. Hence, a precoder satisfying the three conditions not only reduces strength of a signal of the precoder but also increases strength of interference heading to others. ) and
wherein the gain allocation matrix is a square matrix including a plurality of diagonal components, and each of the plurality of diagonal components is relative loss information of a corresponding one of the plurality of transmission paths.
