Messung in Funkkommunikationssystemen

摘要

The present invention relates to measurement in radio communication systems. In particular, the present invention relates to a sounding method in a cellular wireless communication system, the communication system itself and its components like base stations and mobile stations. The radio communication system (1) comprises at least one mobile station (2) and at least two base stations (3, 4). One of said base stations is a serving base station (3) for the mobile station (2) and the at least one further base station is a neighboring base station (4) of the serving base station (3). The serving base station (3) is adapted to generate a schedule for measurement signals and to transmit said schedule to the mobile station (2) and to the neighboring base station (4). The mobile station (2) is adapted to transmit measurement signals in accordance with said schedule to the serving base station (3) and to the neighboring base station (4). Furthermore, the neighboring base station (4) is adapted to calculate a mean channel state for the uplink channel from the mobile station (2) to itself (4) and to transmit said mean channel state to at least one further base station of the radio communication system (1), so that said base station can be provided with channel estimations for uplink channels between the mobile station (2) and all base stations within a certain area surrounding itself.
