Abstract
The object of the invention is a method to determine channel information in a cellular system, in which method user information is transmitted in information frames, which are transmitted by the current cell base station, and in which method neighbor cell base station information (,) is received in order to synchronise to the neighbor cell base station. Preferably the method can be used to speed up or to enable the determination of channel information in connection with handover from the area of one base station to another. In the method according to the invention the user information transmission/reception is preferably interrupted during the reception (,) of user information, which can be i.a. the signal level, the base station identity code (BSIC). In an urgent situation, during a rapid handover from one cell to another, said information can then be received at a sufficient rate, in other words also when an idle frame (,) can not be obtained in a favorable way. The information is not received simultaneously with the transmission/reception of user information, so that only one receiver is required.
