Abstract: According to an example, a communication terminal is described comprising a determiner configured to determine cell search control information including at least a radio access technology to be searched for, a search duration, a number of search iterations, a number of antennas to be used for the search and based on at least one of information about the current radio conditions that the communication terminal is experiencing, position of the terminal, historical information about the presence of the radio cells at the position of the communication terminal, communication terminal attach history in terms of moving from some specific RATs/cells to other specific RATs/cells, proximity sensors' information and a transceiver configured to perform a cell search based on the determined cell search control information.

Abstract: Examples provide a method for clock calibration. A wireless communication device includes a first clock and a second clock. The first clock is turned off but the second clock runs during the inactive state of the wireless communication device. A frequency offset of the first clock is measured with respect to a reference frequency based on a signal received from a network. A virtual timer, which is a software-based timer is updated based on the frequency offset. A drift of the second clock is measured over a predetermined time interval based on the virtual timer. The virtual timer is restored based on the drift after wake-up from the inactive state. Alternatively, a clock frequency relation between the first clock and the second clock may be measured and a phase locked loop (PLL) may be controlled based on the measured clock frequency relation.
