    摘要： The present invention relates to a method and an arrangement in a first communication node (115) for adjusting a channel quality report transmitted between the first communication node (1 15) and a second communication node (105). The first communication node (115) and the second communication node (105) are comprised in a wireless communication network (100), and are adapted to communicate with each other via a radio link (1 10). In a first step, a channel quality report is received (600) from the second communication node (105). The channel quality report is established by the second communication node (105). Then at least one channel characteristic parameter is obtained (601 ). The next step is to determine a channel quality offset based on the obtained channel characteristic parameter. Based on the channel quality offset, the channel quality report is adjusted (605).

    摘要： A method, an apparatus and a computer program for controlling updating of a signal quality target (405) for power control of an ongoing radio transmission (101) in a radio communication system (SYS1), wherein the signal quality target is updated based on communication quality. The method includes detecting (301) a change in transmission format from a first transmission format to a second transmission format for the radio transmission. Any updates causing the signal quality target to increase due to communication quality being below a set communication quality target are blocked (302) for a predefined blocking period after detecting said change in transmission format.

    摘要： In a method and device, simple hardware such as a standard User Equipment (UE), a mobile telephone, is used to collect the impulse response of a radio channel. The data generated is used to classify radio channels based on the impulse response estimates by estimating distribution parameters of the impulse response. This makes it possible to distinguish between different types of fading and hence, radio environments by matching the parameters to known radio channel models.
