Abstract: Various arrangements for generation of a grandmaster timing signal within a cellular network are provided. A first master base station can transmit grandmaster timing signals to various other base stations. A determination can be made that the first master base station is no longer eligible to generate the grandmaster timing signals. The cellular network can identify a second master base station based on one or more parameters and can assign it to transmit grandmaster timing signals. In response to the assignment, the second master base station can transmit the grandmaster timing signals to other base stations.

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.

Abstract: Arrangements for performing cellular network timing are presented. A light base station which is to serve as a timing grandmaster can be assigned. The master light base station includes a radio unit (RU) and a router, but does not include an onsite distributed unit. The router of the light base station can include a global navigation satellite system (GNSS) receiver. The distributed unit (DU) for the light base station is hosted remotely at a local data center (LDC) that communicates with the master light base station via a network. The master light base station can generate a grandmaster timing signal based on a signal received by the GNSS receiver and a clock signal of a local oscillator. The master light base station can transmit the grandmaster timing signal to LDC that hosts the DU for the master light base station and other light base stations.
