摘要： A method for radio resource control is carried out in a radio communications system including multiple base stations. In this method, a radio resource that can be used by the base stations is divided into multiple first radio resources on the frequency axis. Then one or more of the first radio resources are allocated to a second radio resource for initially transmitting a packet and the other first radio resources are allocated to a third radio resource for retransmitting the packet.

摘要： Timing division multiplexing is conducted between the cells to avoid intercell interference. Transmission timing in a time slot pattern has a given interval. A base station determines the transmission timing based on measured uplink interference power. For example, an uplink time slot pattern in which the measured uplink interference power is smaller is selected. A downlink time slot pattern is assigned so that a response to HARQ is returned at that timing. If traffic is busy, additional time slot pattern may be assigned. In determination of the traffic volume, for example, the queued buffer size, the number of connected terminals, or the number of connections to a higher-level device can be used. Assignment timing can be an initial setup time, or a fluctuation detection time of a channel which can be realized by collection of report information on a downlink communication quality, periodic monitor of uplink interference information.
摘要翻译：在小区之间进行时分复用以避免小区间干扰。时隙模式中的发送定时具有给定的间隔。基站基于测量的上行干扰功率来确定传输定时。例如，选择其中测量的上行链路干扰功率较小的上行链路时隙模式。分配下行链路时隙模式，使得在该定时返回对HARQ的响应。如果流量繁忙，可能会分配额外的时隙模式。在确定流量时，例如可以使用排队的缓冲区大小，连接的终端的数量或到较高级设备的连接数。分配定时可以是通过收集关于下行链路通信质量的报告信息，上行链路干扰信息的周期性监视来实现的信道的初始建立时间或波动检测时间。

摘要： Conventionally, different HARQ processes 801 and 802 (subframes T1 and T2) transmit data packets B and D, respectively. One data packet corresponds to one process and is retransmitted as necessary one by one on a process basis, degrading the usage efficiency of frequency and time resources. To solve this problem, downlink data packets B and D, when needed to be retransmitted, are spatially multiplexed in the different HARQ processes 801 and 802. The data packets are simultaneously retransmitted to the same terminal as process 805 (subframe T3).

摘要： In a conventional OFDMA/SCFDMA communication scheme, frequency resource assignment information is exchanged between BSs via a wired interface and used for control of inter-cell interference or the like. When a BS performs assignments of frequency resources, taking the status of a neighbor BS signaled via the wired interface into account, it might be impossible to follow a change in the status of the assignments of frequency resources at the neighbor BS due to a delay occurring in the wired interface. BS selects and assigns distributed frequency resources or continuous frequency resources, depending on the position of an MS in the cell and the transmit power of the BS.

摘要： Interference applied to neighbor cells during terminal handovers can be reduced in wireless communication systems containing base stations having different cell sizes. A serving cell makes handover judgment criteria easier based on pre-acquired cell size information on its own cell and cell size information of neighbor cells in order to facilitate terminal handovers from a base station with a large cell size to a base station with a small cell size. The serving cell finds evaluation function values based on the propagation state (e.g. reference signal received power) between the terminal and target cell, and the interference and load information exchanged between the base stations, and selects the terminal for handover by comparing the evaluation function value with the handover criteria value. The system selects a target cell having a good effect in lowering interference such as a cell with large reference signal received power acquired from a terminal, to serve as the handover destination.
摘要翻译：在包含具有不同小区大小的基站的无线通信系统中，可以减少在终端切换期间应用于相邻小区的干扰。为了便于从具有大小区大小的基站到具有小小区的基站的终端切换，服务小区基于对其自己的小区的预获取的小区大小信息和相邻小区的小区大小信息来更容易地进行切换判断标准尺寸。服务小区基于终端与目标小区之间的传播状态（例如，参考信号接收功率）以及基站之间交换的干扰和负载信息来找到评估函数值，并通过比较评估函数值来选择切换终端具有切换标准值。该系统选择具有从终端获取的具有大的参考信号接收功率的小区等降低干扰效果的目标小区，作为切换目的地。

摘要： In a radio-communication system, when wanting to perform high-accuracy scheduling in a base station, a large number of information items, such as channel quality information, desired precoding matrix information and so on, are fed back from a mobile station with a high degree of accuracy. The base station monitors the feedback information and, upon acquisition of it, transmits to the mobile station a certain kind of feedback information which is judged to contribute to scheduling accuracy improvement while preventing the other kinds of feedback information from being sent to the mobile station.

摘要： A femtocell base station collects the terminal distribution within the cell and selects terminals to represent the cell-center and the cell-edge from among the terminals within the cell. The femtocell base station also calculates maximum transmit power for the respective the cell-center and cell-edge terminals allowable by the macrocell base station. The femtocell base station sets the respective transmit power of the cell-center and the cell-edge in a range that will not exceed the maximum transmit power, adjusts the transmit power control parameter to allow control by the terminal at the power value that was set, and notifies the terminal. Communication with high throughput can in this way be attained for terminals in cells within the femtocell base station during uplink communications to the femtocell base station, and interference applied to the terminals in the macrocell base station can be suppressed.

摘要： An object of the invention is to provide a wireless communication system in which the load of each cell and interference between cells are taken into account. In a handover-candidate base station and a handover-source base station, parameters for interference-reducing scheduling and handover facilitating processing are adjusted based on the mutual load information. When the handover-candidate base station, to be used for load balancing, is a large-diameter cell, transmit power control and frequency scheduling are adjusted by taking account of the load state at a cell edge. When the handover-source base station has a small-diameter cell, the number of terminals to be handed over is adjusted by taking account of the load state of the handover-candidate base station. Thus, both of interference control and load balancing are achieved.
