A method is provided for assigning a time stamp to a specific data packet which, as with a group of received data packets, is received by a cyclically operating sensor. The specific data packet is especially part of the group of received data packets. The disclosed method includes: determining the time of arrival of each data packet of the group of received data packets; assigning a time stamp to each data packet of the group of data packets; determining the time difference between the determined time of arrival and the assigned time stamp for each data packet of the group of data packets; determining the smallest time difference from among the determined time differences; and assigning a time stamp to the specific data packet on the basis of the time of arrival determined for the data packet for which the smallest time difference has been determined.

Assigning time stamps to received data packets

A mobile unit as well as a method for time-stamping a first message of the first mobile unit to a second mobile unit are provided. The method includes the steps of: determining a roundtrip time between the first mobile unit and a base station, receiving the first message sent by the first mobile unit in the base station, adding a timestamp to the first message in the base station while taking into account the roundtrip time, and sending the time-stamped first message to the second mobile unit.

A method is provided for assigning a time stamp to a specific data packet which, as with a group of received data packets, is received by a cyclically operating sensor. The specific data packet especially is part of the group of received data packets. The method includes: determining the time of arrival of each data packet of the group of received data packets; assigning a time stamp to each data packet of the group of data packets based on a first reference point in time; determining the time difference between the determined time of arrival and the assigned time stamp for each data packet of the group of data packets to provide a group of time differences; determining negative time differences from among the group of time differences, for the data packets of which it has been determined that the time of arrival preceded the respective assigned time stamp; determining the negative time differences that are not to be classified as outliers; determining a second reference point in time taking into account the negative time differences that are not to be classified as outliers; and assigning a time stamp to the specific data packet based on the second reference point in time.
