The present invention relates to an apparatus, method and computer program for estimating a multi-hop radio channel. Embodiments relate to an apparatus, method and computer program for estimating a multi-hop radio channel between a transmitter (100), one or more relay stations (150) and a receiver (200) in a mobile communication system (400). The device includes one or more interfaces (12) for obtaining information related to the position and motion status of the transmitter and receiver, information related to the environment of the transmitter, receiver and one or more relay stations, and information related to the transmitting Information related to channel state feedback of a single-hop radio channel between a machine, a receiver and one or more relay stations, and information related to delays of the channel state feedback. The apparatus further includes a control module (14) configured to control the one or more interfaces (12), wherein the control module is further configured to determine information related to channel status and configuration of the multi-hop radio channel based on the above information.
Description
technical field [0001] The present invention relates to an apparatus, method and computer program for estimating a multi-hop radio channel between a transmitter, one or more relay stations and a receiver in a mobile communication system, more particularly but not exclusively to channel conditions at delay Design of multi-hop channel estimation in the inter-vehicle multi-hop communication scenario in the presence of information (CSI) feedback. Background technique [0002] Direct communication between portable devices and vehicles is a feature of some mobile communication systems. Future cars may include communication systems that allow direct data communication between vehicles. A very prominent example is the direct transmission according to the IEEE (Institute of Electrical and Electronics Engineers) 802.11p standard (and corresponding upper layer standards). A common use for such vehicle connectivity standards is to broadcast information to neighboring vehicles. This c...
