摘要：
The present invention relates to methods and arrangements in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves (710) the RS transmission bandwidth, determines (720) a RS measurement bandwidth based on this RS transmission bandwidth, and transmits (730) the determined bandwidth to the UE. The UE receives (810) the RS measurement bandwidth and measures (820) the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability.
