摘要： A base station is configured to control a wireless communications network cell of a wireless communications network. The base station is configured to establish a connection to a first user equipment and to a second user equipment using a random access process. For establishing the connection to the first user equipment, the base station is configured to use a sequence of a first random access preamble, the sequence having a first length. For establishing the connection of the second user equipment, the base station is configured to use a sequence of a second random access preamble, the sequence having a second length.

摘要： A transmitter is configured to transmit at least one signal with a pilot sequence having a plurality of pilot symbols, wherein the transmitter has a signal generator, wherein the signal generator provides the pilot sequence, wherein the signal generator provides the pilot sequence such that the pilot sequence has at least two symbol groups each having at least two pilot symbols, and the symbol groups, when evaluating a signal received by a receiver as a result of the transmission of the signal with respect to a phase, the symbol groups generate phase errors that depend on a temporal off-set between a reference point in time of the transmission of the signal by the transmitter and a value assumed and/or estimated for the evaluation for the reference point in time, said phase errors essentially mutually compensating each other across the symbol groups in the evaluation.

摘要： The invention refers to a transmitter that emits data in the form of a group of at least two partial telegrams that together include the data and that are shorter than an individual telegram comprising the data. The transmitter emits the group of partial telegrams according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial telegrams. Furthermore, the transmitter emits the group of partial telegrams several times and at least twice. Furthermore, the invention relates to a receiver and corresponding methods.

摘要： In embodiments, data transmitters and data receivers use, in a first mode, a first hopping pattern and a second hopping pattern for a repeated transfer of data, and, in a second mode, a third hopping pattern for the single transfer of data, wherein the hopping patterns of the first mode and the second mode are different so that a collision probability in the repeated transmission of data by a further data transmitter in a respectively different mode may be decreased and the transmission reliability may therefore be increased.

摘要： 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.
