摘要： A method for uplink power control at a mobile station which is served by a base station of a communications network comprising a plurality of base stations is provided where the power spectrum density of the mobile station is adaptable based on the bandwidth scheduled to the mobile station. The suggested power spectrum adaptation is obtained by providing for a switch to an alternative power control mode which enables for transmit power boosting at the mobile station. The decision whether to apply the suggested power spectrum adaptation can be made at the base station which is serving the mobile station, or at a selected mobile station.

摘要： A method performed in a wireless network includes receiving signals within a downlink frequency domain to enable channel estimation and measuring two or more signals only for two or more frequency bands of the downlink frequency domain that correspond to two or more uplink frequency bands associated with a scheduling grant or channel allocation that correspond to physical uplink channel frequency bands. The method also includes calculating path loss values for each of the frequency bands and calculating a total power based on the path loss values corresponding to the frequency bands. The method further includes determining a power allocation per frequency band based on the calculated total power to be applied to an uplink transmission and allocating the total power.

摘要： A method in a wireless network containing a first node and an adjacent second node for determining an uplink received power target value of the second node to be used by a user equipment which is to be served by the second node includes establishing the uplink received power target value of the first node. The method also includes obtaining the downlink power capacity of the first node and obtaining the downlink power capacity of the second node. Additionally, the method includes calculating the difference in downlink power capacity between the first node and the second node and determining the uplink received power target value of the second node based on the calculated difference in downlink power capacity between the nodes and the established uplink received power target value of the first node.

摘要： An object of the present invention is to provide a mechanism for handling a handover in a more efficient way. The invention relates to a method in a mobility controller (180) in a radio access network for preparing a handover. The method comprises the following steps to be taken during data transmission between a mobile terminal (140) and a source base station (120), before the handover: Sending a request to a candidate base station (122), which request aims at measuring and reporting timing alignment to be used by the mobile terminal (140) when communicating with the destination base station (122) after the handover, if the candidate base station becomes the destination base station (122) after the handover; receiving a report from the destination base station (122) comprising said requested timing alignment; and when the destination base station (122) is selected among the at least one candidate base stations, sending a message to the mobile terminal (140) to use said timing alignment received from the destination base station (122) when communicating with the destination base station (122) after the handover.

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： 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. The first value and said second value are different. In alternative embodiments, the second set of signals are transmitted taking into account information from the serving cell and a neighbouring cell, while the first set of signals are transmitted taking into account information from the serving cell only.

摘要： A system includes a first device (110) to classify data as one of a control message or a non-control message, and provide the classification of the data to a second device (122). The second device (122) receives the classification of the data, receives information associated with a resource (460), calculates an expected interference associated with the resource (460) based on the information associated with the resource (460), and allocates, to the resource (460), data classified as a control message when the expected interference corresponds to a low expected interference.
