METHOD FOR TRANSMITTING A PILOT SEQUENCE, RELAYING NODE OF A CELLULAR COMMUNICATION NETWORK, AND BASE STATION OF A CELLULAR COMMUNICATION NETWORK

摘要

The present invention refers to Method (101) for.transmitting (111) at least, one pilot sequence (79) over a radio communication link (25) of a radio cell (15) of a cellular communication network (11) from a relaying node (.21). The relaying node (21) Is assigned to a base station (17) of the cell (15), radio resources (53) of the link (25) are subdivided with, respect to frequency (f) and time:(t) into multiple resource elements (65) one or mere of said resource elements (65) being assigned to a control channel of the link (25). In order to provide a method which allows that a terminal can discover one or more relay nodes (21) possibly present in a certain radio cell (15) and perform link quality measurements, it is suggested that the method (101) comprises.; selecting (103} at least, one of said resource element (71) assigned to said control channel as a selected resource element (81) for transmitting said one pilot sequence and transmitting (111) the pilot sequence within the at least one selected resource element (81).
