摘要： A method for scheduling enhanced uplink traffic in a cell in a cellular communication system comprises estimating of a rise-over-thermal measure for the cell. A momentary total load in the cell is computed based on the estimated rise-over-thermal measure. A load headroom is determined from at least a maximum allowed load and the momentary load. Future enhanced uplink traffic is scheduled in dependence of the determined load headroom. A degree of underutilization of enhanced uplink traffic grants in the cell is established. The scheduling comprises overbooking of enhanced uplink traffic in dependence on the established underutilization degree. A network node comprises corresponding functionalities.

摘要： The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and an enhanced Dedicated Physical Data Channel, E-DPDCH are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining (S31) a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced (S32) to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. A DPDCH transmission status is determined (S33), whereupon a power scaling procedure is selected (S34) based on the determined DPDCH transmission status. The selected power scaling procedure is applied (S35) on the uplink transmission.

摘要： A system and method for improving soft hand-off in a CDMA system uses mobile station location and velocity information to maintain soft hand-off legs with those cells in which the mobile station is more likely to be located. The system and method of the present invention estimates the weighted probability of the mobile station arriving in neighboring cells and produces 'bias' values for those cells that the mobile station is more likely to be entering or to be located in. These bias values are used for modifying signal quality values for those cells, and for determinig whether the current cell or neighbor cells are to be placed in an active set so as to establish, or maintain, soft hand-off legs. The system and method of the present invention thus chooses those cells which are more likely to be retained as soft hand-off legs and therefore reduces the overall number of soft hand-offs.

The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised βed,k value’, is reached for all E-DPDCH gain factors βed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.

For example, a method, performed by the RNC, for configuring at least one radio bearer between a radio base station, RBS, and wireless communication devices. The method comprises receiving, from the RBS, a request to perform a TTI switch according to a TTI switch trigger received by the RBS. The received request is analyzed and a grant to perform the requested TTI switch is sent to the RBS.

摘要： The present disclosure concerns interference congestion control in radio communication networks. Disclosed herein are methods as well radio network nodes. A radio network node may, for example, estimate a neighboring cell interference. The radio network node may also detect a sudden significant increase in the estimated neighboring cell interference. In response to detecting a sudden significant in the estimated neighboring cell interference, the radio network node may also transmit a message to at least one other radio network node. This message may include an indicator indicating to said at least one radio network node to initiate an interference congestion control procedure. Hereby it is made possible to allow for interference congestion control in radio communication networks.
摘要翻译：移动宽带业务在无线网络中已经爆炸，导致干扰增加和操作员控制减少。网络也正在变得越来越多，在干扰管理中增加了需求。调度器基于通常假定最坏情况的负载预测算法来调度来自UE的上行链路传输。然而，UE并不总是使用授权的全部功能，因此浪费了大量授权的无线电资源。为了解决这些和其他问题，描述了准确预测/估计其他小区干扰和热噪声以及准确地预测/估计负载利用概率和方差的技术。本发明的估计技术可用于调度UE以更充分地利用可用的无线电资源。扩展卡尔曼滤波可以适用于提供低阶计算复杂度的估计。
