摘要： A method of decreasing radio link failure in challenging mobility scenarios for a user equipment (UE), device working in a cellular telecommunication network with a base station of each cell is disclosed. The method comprises measuring signal conditions for serving cell and neighbouring cells periodically; and estimating channel variations and comparing the estimate with a threshold value such that, when channel variations are determined to exceed a channel variations threshold, performing an accelerated procedure comprising predicting whether handover is likely to occur in connection with the next scheduled measurement instant based on the signal measurements such that when handover is predicted, the procedure directly proceeds with sending an initial measurement report transmission request. Thereby handover delay can be reduced such that risk of radio link failure is reduced at significantly varying signal conditions. A UE device and a computer program are also disclosed.

摘要： Methods and apparatus for have frequency offset estimation and cell search in radio communication systems take into account the time-frequency correlation properties of reference and synchronization signals in such systems. This reduces the probability of misdetection of the physical layer cell ID and frequency offset by accounting for time-frequency ambiguities and evaluating correlation signal peaks in the frequency domain, saving signal processing time and making initial cell search considerably faster. Also, lower-grade and hence cheaper oscillators can be used without causing problems in the user's experience with a receiver, such as a cellular telephone.
