CONTROL DEVICE, COMMUNICATION NODE AND METHODS THEREOF

摘要

The present invention relates to a control device and a communication node. The control device (100) comprises a processor (101) and a transmitter (103); wherein the processor (101) is configured to generate a composite beam control signal S, wherein the composite beam control signal S comprises antenna beam control information for communication nodes of a communication path comprising a source communication node, at least one intermediate communication node and a destination communication node; and wherein the transmitter (103) is configured to transmit the composite beam control signal s to at least one communication node of the communication path. The communication node (300) comprises a processor (301), a transceiver (303), reception antenna elements (305) and transmission antenna elements (307); wherein the transceiver (303) is configured to receive a composite beam control signal S, wherein the composite beam control signal s comprises antenna beam control information for communication nodes of a communication path comprising a source communication node, at least one intermediate communication node and a destination communication node; wherein the processor (301) is configured to derive antenna beam control information associated with the communication node (300) from the composite beam control signals; and control the beam of the reception antenna elements (305) or the beam of the transmission antenna elements (307) according to the antenna beam control information. Furthermore, the present invention also relates to corresponding methods, a computer program, and a computer program product.
