    摘要: A method for cooperative control of power among base stations and a base station device which performs the same are discussed. A first receiving unit is configured such that a specific base station in a cooperative unit receives, from a specific terminal located on a cell edge of the specific base station, token value information which indicates an average transmission rate of the specific terminal and the up-to-date level of satisfaction of the minimum average transmission rate of the specific terminal. A second receiving unit receives, from one or more other base stations in the cooperative unit, information containing an average transmission rate of terminals located on edges of each of the base stations, token values of terminals located on cell edges of each of the base stations, and the current power levels of each of one or more base stations.

    摘要: Disclosed is a method for selecting an adaptive CoMP scheme for a user equipment. The user equipment selects a first CoMP set which can maximize a signal to interference-plus-noise ratio (SINR) from among CoMP sets while performing a first coordinate multi-point (CoMP) scheme. Then, the user equipment compares the current data transmission rate thereof and the required minimum data transmission rate thereof and the required minimum data transmission rate while performing the first CoMP scheme and selecting the first CoMP set. Subsequently, the user equipment which performs the first CoMP scheme selects a second CoMP scheme on the basis of the result of the comparison in accordance with a predetermined sequence of CoMP schemes.

    摘要: Disclosed are a control method and a control device for implementing two-way communication in a wireless network. A repeater can measure a channel matrix, which indicates channel information of each of a plurality of nodes based on signals received simultaneously from the plurality of the nodes, and calculate a first basic lattice size, which initializes the lattice sizes of the received signals according to predefined rules. Then, the repeater uses the channel matrix of each of the nodes and the initialized first lattice size to calculate for each of the nodes a first normalization factor, which normalizes the sizes of the signals simultaneously received from each of the nodes, and a minimum normalized factor, which is equivalent to the minimum value of the first normalization factor. And then, the repeater calculates a second lattice size for each of the nodes using the first normalization factor, the minimum normalization factor, and the initialized first lattice size, which have been calculated for each of the nodes. Then, the repeater calculates a second normalization factor using the second lattice size and the channel matrix of each of the nodes. And then, the repeater transmits the new calculated lattice size and the normalization factor to each of the nodes.
