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： Embodiments herein relate to a method in a radio base station for estimating a noise floor in a cell of a radio communications network. The radio base station is comprised in the radio communications network and serves the cell in the radio communications network. The radio base station determines a time interval in which time interval the noise floor in the cell is to be estimated. The radio base station further reduces a first interference during the determined time interval in the cell and then measures a second interference in the cell at a time in the time interval in the cell. The radio base station then estimates the noise floor using the measured second interference.

摘要： A method of allocating radio resources to communication links of a wireless communication system based on status parameters of each of the links, the communication system having a plurality of network nodes, a plurality of relays associated with the network nodes, and a terminal accessing the communication system. A first radio resource allocation may be determined by balancing the performance of a relay-to-network-node communication link of each relay against the performance of a corresponding terminal-to-relay communication link. A second allocation may be determined by balancing the performance of the relay-to-network-node communication link of each relay against the performance of a terminal-to-network-node communication link. A final allocation may be determined by calculating a weighted average value of the first and second allocations.

摘要： Techniques are provided to obviate unnecessarily requesting that different types of measurements are simultaneously made by a user equipment unit (30) in anticipation of a handover in a radio access network. In accordance with one aspect of the technology, in preparing a measurement request for a user equipment unit (served by a currently utilized cell) to measure on signal(s) transmitted from other cell(s) for evaluating handover potential; a network node uses at least one deployment parameter for selecting between three measurement alternatives for the measurement request. In a generic embodiment, the three measurement alternatives are: (1) performing only a first type of measurement(s); (2) performing only a second type of measurement(s): and (3) simultaneously performing both the first type and the second type of measurement(s). In a more specific example embodiment, the three measurement alternatives are: (1) performing only an inter-frequency measurement(s): (2) performing only an inter-radio access technology measurement(s); and (3) simultaneously performing both inter-frequency measurement(s) and inter-radio access technology measurement(s).

摘要： The invention relates to the control and adaptation of transmit parameters for wireless communication between a transmitter (TX) and at least one receiver (RX) to provide joint power and link adaptation. A basic idea of the invention is to collectively determine the transmit duration (T) and transmit power (P) of the transmitter based on minimization of a given objective function representative of total consumed energy, on both the transmitting side and the receiving side, with respect to transmit duration and/or transmit power. In effect, this means that link transmit parameters are determined based on the energy consumption on both the transmitting side and the receiving side. In addition, both transmit power and transmit duration are varied, while minimizing overall consumed energy.
摘要翻译：本发明涉及用于发射机（TX）和至少一个接收机（RX）之间的无线通信的发射参数的控制和调整，以提供联合功率和链路自适应。本发明的基本思想是基于在发射侧和接收侧上表示总消耗的能量的给定目标函数的最小化来共同地确定发射机的发射持续时间（T）和发射功率（P）关于传输持续时间和/或传输功率。实际上，这意味着基于发送侧和接收侧的能量消耗来确定链路发送参数。此外，传输功率和发射持续时间都是变化的，同时最小化总消耗的能量。
