Abstract: A method performed by a first radio network node for handling communication in a wireless communications network providing, is provided. The wireless communications network comprises the first radio network node (131) and a second radio network node (132) relaying data packets between a central network node (12) and a UE (10). The first radio network node is an intermediate network node between the second radio network node and the central network node. The first radio network node detects (701) congestion over a link towards the second radio network node. Upon detection of the congestion the first radio network node adds a marking in a header in a data packet and transmits (702) the data packet towards the second radio network node.

Abstract: A method and a camera provide an estimation of a mean signal to noise ratio value for an output image comprising a number of pixels, wherein each pixel of the output image has a pixel value. An image histogram divided into bins, the image histogram having information regarding the distribution of pixel values among the pixels of the output image. Each bin has a set of pixels having pixel values within a predetermined range. For each bin of the image histogram, a signal to noise ratio value of that bin may be attributed and weighted with the number of pixels in the set of pixels of that bin. The weighted signal to noise ratio values of the bins are summed, and the sum may then be divided by the total number of pixels of the output image or the total number of pixels in the bins of the image histogram.
