摘要： In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level. Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads.

摘要翻译： 在多址系统中，通过基于第一接入网络中确定的负载水平（ULOCAL）来选择信号强度阈值水平来实现接入选择原理。 如果有经验的信号强度超过信号强度阈值水平，通常由多于一个接入网络覆盖的区域中的新用户尝试分配给第一接入网络。 通过使用适当的负载水平依赖性，通信实用程序可以优选地被最大化或者至少被考虑在内。 通过在负载水平接近容量限制时增加阈值，避免了完全填充的第一接入网络。 这给了一个机会让特别适合用户仍然可以访问第一个接入网络。 同时，由于在实际访问尝试之前决定了优选访问，所以即使在非常高的流量负载下也可以显着地减少控制信令。

摘要： A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels, between the first cell region and at least a second cell region. The invention has a particular advantage in TDD mode of operation where efficient and dynamic interference mitigation is needed to combat the inherent mobile-to-mobile and base station-to-base station interference.

摘要： The present solution relates to a method in a first communication node (201) for determining an indication of channel quality of a radio channel (205) between the first communication node (201) and a second communication node (203). The first communication node (201) and the second communication node (203) are comprised in a wireless communication network (200). The radio channel (205) comprises a plurality of sub bands. First, at least two channel quality reports are obtained (701) for different time instances.

摘要： According to embodiment of the present invention, there is provided a radio base station (20) and a corresponding method for estimating the quality of the uplink control channel. The method comprises measuring (32, 42) a quality parameter of the uplink data channel, and using (38, 50) this to estimate the quality of the uplink control channel. In one embodiment, measurements of the uplink control channel are taken and their reliability determined. If the reliability is low (i.e. below a threshold, or below the respective measurements taken on the uplink data channel), then measurements on the data channel are used instead of those made on the control channel to estimate the control channel quality.

摘要： Methods for downlink power control in wireless communication systems are provided. In response to a transmitter power change request from a mobile terminal (110) over a wireless connection, a base station (122) determines a power control parameter based on its current total transmitter power PDL. The power control parameter preferably relates to a maximum connection-specific transmitter power, a power step size and/or a power increase probability, and is used by the base station to distribute transmitter power pi to the connection.

摘要： The present invention provides a user equipment for a telecommunications system, the telecommunications system comprising at least a first radio basestation. The user equipment comprises means for controlling a transmission power of the user equipment, such that said transmission power has a first value for a first set of one or more signals sent over a physical channel between the user equipment and the first radio basestation.
