摘要： A wireless resource allocation apparatus performs determining an amount of VoIP traffic for each terminal station; determining whether semi-persistent scheduling or dynamic scheduling is used for transmitting each packet of the VoIP traffic, based on a result of the determination for the amount of the VoIP traffic; managing, for each terminal station, a resource block allocated in the semi-persistent scheduling; and managing each resource block which is not managed for the allocation in the semi-persistent scheduling and is allocated in the dynamic scheduling. If it is determined that the dynamic scheduling is used for transmitting each packet of the VoIP traffic to a terminal station, the resource block, which has been managed for the relevant terminal station as a resource block allocated in the semi-persistent scheduling, is released, and the released resource block is managed as a resource block allocated in the dynamic scheduling.

摘要： A transmission power control device is able to capture the serving sector measurement information of a mobile station with respect to a serving sector and the neighboring sector measurement information of the mobile station with respect to a neighboring sector. The transmission power control device selects a power control mode based on a decision as to whether or not the neighboring sector measurement information has been captured in an applied time in the past. The power level of a mobile station is determined based on the selected power control mode. Thus, it is possible to reduce inter-cell interference and inter-sector interference because the power level of a mobile station is determined in light of communication environments, even though the mobile station is connected with a base station in an LTE-based communication system which cannot always detect the neighboring sector measurement information.

摘要： A radio frame control device comprises a controlling unit, a resource block allocation unit, and a resource block conversion unit. The controlling unit controls a downlink radio frame of an orthogonal frequency division multiple access scheme. The resource block allocation unit allocates resource blocks to a terminal station using any one of a plurality of resource block allocation methods respectively having different restrictions. The resource block conversion unit determines whether or not conversion is possible from allocation information of resource blocks allocated according to a first resource block allocation method into resource block allocation information by a second resource block allocation method. The resource block conversion unit converts the resource block allocation method for the resource block allocation information when the conversion is possible.
