摘要： A method for cell selection comprises obtaining of user equipment specific information for a user equipment that is present in a first cell of a first base station. The user equipment specific information comprises information of a prevailing radio situation and information of a present decoding performance. A present capability of the user equipment for handling increased interference and a measure of a cell selection offset required to cover the user equipment by a second cell is estimated from the user equipment specific information. It is decided on modifying a cell selection offset for handover between the first cell and the second cell, in dependence on the estimated present capability of the user equipment for handling increased interference and the cell selection offset required to cover the user equipment by the second cell.

摘要： The invention relates to handover of a mobile station (12) from a source cell (C1) to a target cell (C2) in a wireless communication network (10, 11). According to the invention communication improving data in relation to communication between the source cell and the mobile station (12) is collected by a communication improving node (14) prior to handover and communication improving physical layer data being at least based on said collected communication improving data is transferred to a device (41) handling communication between the target cell and the mobile station. The communication handling device then uses the communication improving physical layer data to improve the quality of the initial communication between the mobile station and the target cell after handover to the target cell.

摘要： A receiving node makes an early estimate of the outcome of a decoding attempt and sends a corresponding early feedback (EHF) to the sending node. This has an effect of enabling a fast retransmission of the data by the sending node in case the decoding by the receiving node is likely to fail. An advantage of this is that any delays due to data retransmission may be minimized, resulting in a higher average throughput of the data transmission between the nodes.
摘要翻译：接收节点对解码尝试的结果进行早期估计，并向发送节点发送相应的早期反馈（EHF）。这具有在接收节点的解码可能失败的情况下能够由发送节点快速重传数据的效果。这样做的一个优点是可以将由于数据重传引起的任何延迟最小化，导致节点之间的数据传输的平均吞吐量更高。

摘要： A method and a network node (110, 111) for determining first channel state information in an upcoming time slot for use by a first radio network node (111) when determining a set of radio transmission parameters for a transmission between the first radio network node (111) and a second radio network node (121) are provided. The net work node (110, 111) receives (201) second channel state information for said upcoming time slot. Furthermore, the network node (110, 111) determines (207) third channel state information for said upcoming time slot. The second and third channel state information are at least partly non-overlapping with each other. Next, the network node (110, 111) determines (208) the first channel state information, for said upcoming time slot, based on the second channel state information and the third channel state information.

摘要： A method is disclosed for use in a heterogeneous telecommunications system of the kind comprising a macro base station and a low-power base station, the low-power base station having a coverage which is extendible by range expansion, RE, to serve a user equipment which would otherwise have been served by the macro base station. According to the method, which is performed in either of the macro base station or the low-power base station, information about radio conditions of the user equipment at least with respect to the macro base station is obtained (310). Based on the obtained information, it is determined (320) whether a criterion for conditional range expansion is satisfied, said criterion being related to the uplink transmission power of the user equipment to the macro base station. Accordingly, range expansion is applied (330) for the user equipment only when the criterion is satisfied. A corresponding base station, telecommunications system and computer readable storage medium are also disclosed.

摘要： A method and arrangement in a radio communication network for predicting channel quality on a downlink channel. A radio base station (RBS) transmits data on the downlink channel to one or more user equipments (UEs), each of which transmits a channel quality indicator to the RBS on an uplink channel. The RBS derives a needed downlink transmission power from the received channel quality indicator, and predicts a channel quality for a next downlink transmission based on the received channel quality indicator and the derived downlink transmission power.

摘要： Disclosed herein is a first network node and a method in a first network node for selecting a transport format among a plurality of available transport formats for communicating information with a second network node via a wireless link, which transport formats are such that a first transport format has a first maximum capacity and all the other transport formats have a higher maximum capacity in an increasing order. The method comprises the steps of: obtaining a quality indicator, which quality indicator indicates the current channel quality of the wireless link; determining a throughput indicator, which throughput indicator indicates the throughput format being available at the obtained quality indicator; calculating a switching value based on the quality indicator and the throughput indicator; switching to the second transport format when the quality indicator indicates that the switching value is reached or exceeded with respect to the second transport format; sending a notification to the second node, which notification indicates the switch to the second transport format.
