    Abstract: A method for determining if a handover of a half-duplex terminal has to be executed from a first base station to a second base station, the half-duplex terminal not transferring and not receiving signals during a period of time, called an idle period. The first base station transfers to the half-duplex terminal a downlink signal in the cell of the first base station. The first base station receives a message in response to the downlink signal including information relative to quality measurements on the downlink signal transferred by the first and the second base stations. The first base station determines the round trip delay between the half-duplex terminal and the second base station. The first base station further transmits a handover notification message to the half-duplex terminal instructing the half-duplex terminal to execute a handover procedure from the first base station to the second base station.

    Abstract: The present invention concerns a method for estimating, in a communication system, a level of interference plus noise affecting received signals representative of a set of received pilot symbols, characterized in that the method comprises the steps of: dividing the set of received pilot symbols by a corresponding set of pilot symbols, filtering the divided set of received pilot symbols by a filter the coefficients of which are determined from an eigenvector associated with one of the lowest eigenvalues of a channel fading correlation matrix representative of the correlation between the channel coefficients affecting the set of pilot symbols, averaging up the square absolute values of the symbols obtained at the output of the filter in order to estimate the level of interference plus noise affecting the received signals.
