Abstract
Various arrangements for generating and distributing a grandmaster timing signal for a cellular network are presented herein. A base station can generate a grandmaster clock timing signal based on a signal received by a global navigation satellite system receiver of the base station and a clock signal of a local oscillator of the base station. This grandmaster timing signal may be transmitted to a distributed unit of the base station. This grandmaster timing signal can also be transmitted, via a network, to each base station of a plurality of base stations of the cellular network.

A cellular network timing system, comprising:
- a plurality of base stations;
- and
- a master base station, comprising:
- a radio unit (RU);
- a distributed unit (DU), wherein a central unit (CU), which is in communication with the DU, is hosted by a cloud computing platform remote from the master base station;
- and
- a router in communication with the RU, the DU, and a network, wherein the router comprises a global navigation satellite system (GNSS) receiver, the router being configured to:
- generate a grandmaster timing signal based on a signal received by the GNSS receiver and a clock signal of a local oscillator;
- transmit the grandmaster timing signal to the distributed unit;
- and
- transmit, via the network, the grandmaster timing signal to each base station of the plurality of base stations.
A method for generating and distributing a grandmaster timing signal for a cellular network, the method comprising:
- generating, by a router located on-site at a base station, a grandmaster timing signal based on a signal received by a GNSS receiver of the base station and a clock signal of a local oscillator of the base station, wherein:
- the base station comprises a distributed unit (DU), the router, and a radio unit RU) and
- a central unit (CU), which is in communication with the DU, is remotely hosted on a cloud computing platform that is remote the base station;
- transmitting the grandmaster timing signal to the DU of the base station;
- and
- transmitting, via a network, the grandmaster timing signal to each base station of a plurality of base stations of the cellular network.
