摘要
Disclosed is a method for the performance-optimized formation of a beam, which is less costly than methods known in prior art and ensures minimized transmission power radiation while respecting individual SINR requirements at the mobile stations and taking into account an efficient dynamic resource management. In order not to exceed a given total transmission power while demonstrating a fast convergence behavior, the inventive method is carried out in two steps. In a first step, a subset of K users is determined so as to optimize the SINR balance for a given maximum transmission power rho max of the base station. Solutions SINRi /= gamma i, 1 /= i /= K, exist for said users, gamma i representing the minimum connection quality, and the balanced maximum of relation (A), 1 /= i /= K, is as large as possible among all potential user combinations for said users. In a second step, the total transmission power of the base station is minimized.
