摘要： The invention relates to a method for selecting a channel quality reporting mode for reporting estimated channel quality and to a radio base station (100) adapted to select such a channel quality reporting mode. The reporting mode is selected from a list of predetermined reporting modes. The radio base station comprises a measurement unit (101) adapted to measure a traffic load in the cell (110) and a comparator unit (102) adapted to compare the measured traffic load with a predefined threshold. The radio base station (100) further comprises a selector unit (103) adapted to select a channel quality reporting mode based on a result from the comparison, and a transceiver (104). The transceiver (104) is adapted to send configuration information to a user equipment (120) (UE) to inform the UE of the channel quality reporting mode to use in order to enable the UE to report channel quality estimations of a set up communication channel.

摘要： According to teachings presented in this document, reported channel quality information, as used for controlling one or more aspects of wireless transmission, is compensated according to an aging function that depends on channel variability. In this manner, the "amount" or extent of age-based compensation applied to the channel quality feedback for a given user— e.g., a mobile station or other item of user equipment — varies as function of that user's channel conditions. More particularly, in an advantageous approach, the aging function applied to the channel quality estimates received from a given user depends on estimates of that user's channel variability. Channel quality estimates from (or generated for) a user whose channel conditions are changing very little, or at least are changing very slowly, may be aged less aggressively than those associated with a user whose channel conditions are changing more rapidly.
摘要翻译：根据本文中提出的教导，用于控制无线传输的一个或多个方面的报告的信道质量信息根据依赖于信道变异性的老化功能来补偿。以这种方式，适用于给定用户（例如，移动台或其他用户设备）的信道质量反馈的“量”或基于年龄的补偿程度根据该用户的信道状况而变化。更具体地，在有利的方法中，应用于从给定用户接收的信道质量估计的老化功能取决于该用户的信道变异性的估计。频道条件变化非常小或至少正在变化非常缓慢的用户的（或生成）的频道质量估计可能比与其频道条件正在更快速地改变的用户相关联的用户的年龄更小。

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.
