摘要： The present invention relates to methods and arrangements of controlling an uplink data rate between a user equipment and a communication network node, which are communicating with each other on uplink and downlink data channels over a radio interface. A scheduler is arranged to distribute available scheduling headroom, provided by an uplink load control unit, between user equipments which are to be scheduled. A scheduling grant signalling is sent from the communication network node to the user equipment, based on which the user equipment is able to select a transport format combination (E-TFC).

摘要： The embodiments of the present invention relate to methods and apparatuses (600, 700) for coordinating interference in a telecommunications LTE based system. According to exemplary embodiments, an apparatus acting as a macro radio base station (eNB) (600) is configured to decide on what radio resources to schedule to its UEs and further decide on what resources to leave unutilized. Information on the decided resources is further transmitted in an interference coordinate signalling message, to at least one relay node (RN) (700) via at least one layer (1) control channel. The interference coordination signalling message will assist the RN (700) to make its own scheduling decision based on the information in the signalling message.

摘要： In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.
摘要翻译：在蜂窝无线电系统中，传输功率控制（TPC）功率偏移被设置为使得根据反映进行上行链路TPC命令的下行链路信道的质量的可用的相关测量来调整每个发射无线电基站，由此获得改进的性能。 TPC功率偏移可以例如基于由无线电基站和聚合的UE接收机功率或UE发送的估计的上行链路专用物理控制信道（DPCCH）SINR，TPC“up”的数目和“下”的TPC数量通过N个插槽发射功率。此外，支持软切换的蜂窝无线电系统中使用的移动站也可以适用于基于同时接收的TPC命令的数量和质量来应用TPC丢弃阈值。也可以选择性地执行移动台中的丢弃过程，使得被确定为不可靠的TPC命令不被丢弃，而是基于它们被确定的可靠性而被选择性地丢弃。

摘要： A first network node (111) and a method therein for controlling load in a first cell (121) of the first network node (111) are provided. The first network node (111) comprises a multi-stage receiver. The first network node (111) computes an interference cancellation gain, at an intermediate stage of the multi-stage receiver. Furthermore, the first network node (111) estimates neighbor cell interference from interfering signals while accounting for a load utilization. The load utilization relates to power transmitted and power granted. The first network node (111) calculates a load measure for stability based on at least the interference cancellation gain and the neighbor cell interference. Next, the first network node (111) controls the load in the first cell (121) based on the load measure for stability.

摘要： The present disclosure provides an uplink intra-frequency load balancing method. The uplink intra-frequency load balancing can be performed by adjusting a beam direction of a User Equipment UE. For each of UEs, the method comprises steps of: determining a cell load level of each cell based on an uplink load measurement received from base stations of a plurality of cells; determining a beam-forming capability of the UE based on a beam-forming gain of the UE; and calculating a cell balancing parameter for each of the plurality of cells, according to a common pilot channel CPICH quality report measured by the UE, the cell load levels of the plurality of cells and the beam-forming capability of the UE, so as to determine a beam-forming control cell towards which the beam direction of the UE is directed, the beam-forming control cell being a cell which has an optimal cell balancing parameter among the plurality of cells. The present disclosure further provides, for a UE which supports a CLBF mode but is not in the CLBF mode, a method for selectively activating the CLBF mode so as to enhance the effect of load balancing. The present further provides an uplink intra-frequency load balancing apparatus.

摘要： A wireless terminal comprises a communications interface and a congestion controller. The communications interface communicates over a radio interface with a base station. The congestion controller, upon occurrence of a congestion indication, reduces uplink transmission power of the wireless terminal by lowering a transport format combination for use by the wireless terminal for transmitting an enhanced dedicated uplink channel (E-DCH) over the radio interface to the base station. In an example embodiment and mode, the congestion controller performs an expedited transport format combination reduction procedure which is distinct from Dedicated Physical Control Channel (DPCCH) power reduction based on a command received in a closed loop power control procedure, e.g., on a Fractional-DPCH (F-DPCH) channel.
