Abstract

Methods, computer programs, and apparatuses for determining and using a predicted future quality of service of a wireless communication link between a transceiver and a mobile transceiver. The method includes obtaining information on a position and a movement of the mobile transceiver, determining a predicted received power of the wireless communication link at the mobile transceiver based on the mobile transceiver position, determining a predicted mismatch between an ideal time-frequency-grid configuration and a time-frequency-grid configuration used for the wireless communication link based on the position and movement of the mobile transceiver, determining a predicted throughput of the wireless communication link based on the predicted received power and based on the predicted mismatch between the ideal time-frequency-grid configuration and the time-frequency-grid configuration used for the wireless communication link, and determining the predicted future quality of service of the wireless communication link based on the predicted throughput of the wireless communication link.
