摘要： After a switch of a transmission rate for a mobile station, the next switch of the transmission rate for the mobile station is halted for a predetermined period of time. Thus, deterioration in resource use efficiency can be prevented, and a switch to a high transmission rate for another mobile station requiring the high transmission rate can be smoothly performed, thus the throughput quality can be maintained.A wireless base station or a control station switches a transmission rate for each mobile station in accordance with the amount of information transmitted and received, and, after switching a transmission rate for one of the mobile stations, halts the next switch control of transmission rates for the mobile station for a predetermined period of time, thus optimizing system performance. A switch halt period is variably set depending on whether a current transmission rate and a switched transmission rate are higher or lower, or in accordance with the number of remaining resources.

摘要： A disclosed radio communication apparatus includes a precoding unit, a optimum transmit power calculation unit and a transmission unit. The optimum transmit power calculation unit receives the transmit weight related information from the precoding unit and calculates a transmit power level to optimize an objective function in accordance with an interior point method. The objective function results from addition of a barrier function adjusted with a barrier parameter to an original objective function associated with a constrained optimization problem. The original objective function includes a function of respective channel capacities for individual users derived from the transmit weight related information. The optimum transmit power calculation unit adaptively updates a logarithm of the barrier parameter and uses a gradient obtained through a high-order derivative with the logarithm of the barrier parameter to calculate the transmit power level to optimize the resulting objective function.
