Abstract: Embodiments relate to an apparatus for adjusting channel quality indicator measurements of a channel between a client device and a serving device within a wireless communication system. The apparatus includes a controller adapted to receive, from the client device, a first information and, when the client device is in a handover zone, a second information. The controller is further adapted to transmit according to a switching sequence either the first information alone or the first information together with the second information. The apparatus also includes an adjustment function entity adapted to receive the first information together with the second information and adapted to adjust the first information based on the second information by modifying it or keeping it unchanged. The first information is related to the CQI measurements, while the second information is related to a handover (HO).

Abstract: The application relates to a method and a transmitter communication device configured to provide video data to a receiver communication device, wherein the video data comprises one or more groups of frames and each group of frames comprises a plurality of temporally successive frames. The method comprises processing a first frame of a current, i.e. currently processed group of frames using a first modulation and coding scheme of a plurality of modulation and coding schemes and processing a second frame of the current group of frames using a second modulation and coding scheme of the plurality of modulation and coding schemes, and further selecting the second modulation and coding scheme of the plurality of modulation and coding schemes on the basis of a temporal position of the second frame relative to the first frame of the current group of frames.
