Abstract:
1. A method for controlling power under restriction on synthesized power of terminals and a repeater in a two-way relay network the method comprising: estimating a current channel, at each one of the terminals and the repeater; allocating power and determining a transmission rating, at each one of the terminals and the repeater, by applying previously determined power control parameters when the estimated current channel is substantially the same as a previous channel; selecting one of a dispersion method and a centralized method as a power control method when the estimated current channel is not the same as the previous channel; allocating power and determining a transmission rating, at each one of the terminals and the repeater, by deriving new power control parameters and applying the new power control parameters, when the dispersion method is the selected power control method; and receiving estimated channel information from each one of the terminals and the repeater and deriving new power control parameters at a control unit when the centralized method is the selected power control method and transmitting the new power control parameters to each one of the terminals and the repeater, and allocating power and determining a transmission rating at each one of the terminals and the repeater by applying the received power control parameters.
