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.
