Abstract
The present invention relates to cellular radio communication and in particular to providing information on neighbor cells to enable terminals to perform neighbor cell measurements. In the prior art the terminal attempts to make neighbor cell measurements in a reference signal structure that is the same in the neighbor cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighboring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbor cells.
