Abstract
An object of the present invention is to provide a mechanism of measuring a reference signal that is less over head consuming and less time consuming. The object is achieved by a method for managing uplink channel estimation in a base station. The base station is comprised in a radio access network using Frequency Division Duplex (FDD). The base station is associated with a first cell of a number of cells within the radio access network. The base station is adapted to connect at least one mobile terminal, being situated in the first cell, to a network infrastructure. The method comprises the step of transmitting a redirected reference signal on an uplink band to the mobile terminal. The redirected reference signal is intended for uplink channel estimation.
