The present invention relates to a communication device and an access node. The communication device comprises: a processor, and directional antennas; wherein the directional antennas are configured to receive a first signal Sindicating a calibration request (CR) for an access node; wherein the processor is configured to generate directional beacon signals Sin response to the calibration request (CR); wherein the directional antennas are further configured to transmit the directional beacon signals Stowards the access node (). The access node () comprises: a processor, and an antenna array; wherein the antenna array is configured to receive directional beacon signals Sfrom at least one communication device; wherein the processor is configured to calibrate the antenna array based on the directional beacon signals S.

Communication device, access node and methods thereof

A computing apparatus configured to communicate with nodes of a wireless communication system. The computing apparatus includes a processor configured to receive a radio link measurement corresponding to a user node. The processor determines a physical disturbance based on the radio link measurement and determines an at risk user node and a time at which the at risk user node is likely to experience a radio link disturbance, based on the physical disturbance. The processor then determines a connectivity adjustment for the at risk user node, and sends the determined connectivity adjustment to the wireless communication system.
