Abstract
Embodiments of the present invention provide a base station including bidirectional data transmission to a node. The base station has a receiver for receiving a data packet transmitted by the node at a node transmission frequency, the node transmission frequency being derived from a frequency generator of the node. In addition, the base station has a determiner for determining the node transmission frequency based on the data packet received and for determining a deviation of the frequency generator of the node based on a frequency deviation between the determined node transmission frequency and a set node transmission frequency associated to the node. Furthermore, the base station has a transmitter for transmitting a data packet to the node at a base station transmission frequency, the transmitter for transmitting the data packet being configured to set the base station transmission frequency based on the determined deviation of the frequency generator of the node.
