GRUR 13/2022(2. Juli 2022) - BGH 11.1.2022 – X ZR 4/20 Erreichen der mit einer Zweckangabe intendierten Funktion durch externe Software – SRS-Zuordnung

Der X. Zivilsenat des Bundesgerichtshofs hat auf die mündliche Verhandlung vom 11. Januar 2021 durch den Vorsitzenden Richter Dr. Bacher, die Richter Hoffmann und Dr. Deichfuß, die Richterin Dr. Kober-Dehm und den Richter Dr. Crummenerl

für Recht erkannt:

Auf die Berufungen der Parteien wird das Urteil des 5. Senats (Nichtigkeitssenats) des Bundespatentgerichts vom 12. Dezember 2019 unter Zurückweisung der weitergehenden Rechtsmittel abgeändert.

Das europäische Patent 2 178 232 wird mit Wirkung für die Bundesrepublik Deutschland dadurch teilweise für nichtig erklärt, dass die Patentansprüche die nachfolgende Fassung erhalten:

1. A mobile station apparatus comprising: a mapping unit (307) configured to map a sounding reference signal (SRS) to a subframe; and a transmitting unit (309) configured to transmit the

mapped sounding reference signal (SRS); characterized in that said mapping unit (307) is adapted to map the sounding reference signal (SRS) in a guard time of the subframe in which a random access preamble is transmitted, the guard time during which nothing is transmitted being added to the random access preamble, wherein the guard time is added after the random access preamble, and said mapping unit (307) is adapted to map the sounding reference signal (SRS) in the tail end of the subframe, and wherein the random access preamble is transmitted from

another mobile station apparatus.

2. The mobile station apparatus according to claim 1, wherein said mapping unit (307) is adapted to map the sounding reference signal (SRS) such that a time gap between the sounding reference signal (SRS) and the random access preamble is maximized.

3. The mobile station apparatus according to one of claims 1 to 2, wherein the random access preamble is transmitted from a mobile station apparatus, which is non-synchronized in an uplink.

4. The mobile station apparatus according to one of claims 1 to 3, wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) at a constant period.

5. The mobile station apparatus according to one of claims 1 to 4, wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) at a period which is m/n times of a period at which a random access preamble is transmitted, wherein m and n are positive integers.

6. The mobile station apparatus according to one of claims 1 to 5, wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) at a constant period in at least part of subframes, in which random access preambles are transmitted.

7. The mobile station apparatus according to one of claims 1 to 6, wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) at a constant period in subframes including a subframe, in which a random access preamble is transmitted.

8. The mobile station apparatus according to one of claims 4 to 7, wherein the period is defined by a number of subframes.

9. The mobile station apparatus according to one of claims 1 to 8, wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) using a frequency hopping.

10. The mobile station apparatus according to one of claims 1 to 9 further comprising a receiving unit (302) configured to receive control information related to a time resource of the sounding reference signal (SRS), wherein said transmitting unit (309) is adapted to transmit the sounding reference signal (SRS) based on the control information.

11. A transmitting method comprising: mapping a sounding reference signal (SRS) to a subframe; and transmitting by a mobile station apparatus the mapped sounding reference signal (SRS);

characterized by mapping the sounding reference signal (SRS) in a guard time of the subframe in which a random access preamble is transmitted, the guard time during which nothing is transmitted being added to the random access preamble, wherein the guard time is added after the random access preamble, and said sounding reference signal (SRS) is mapped in the tail end of the subframe, and wherein the random access preamble is transmitted from another mobile station apparatus.

Im Übrigen wird die Klage abgewiesen.

Von den Kosten des Rechtsstreits tragen die Klägerinnen je zwei Fünftel und die Beklagte ein Fünftel.

Von Rechts wegen
