Abstract
Techniques for synchronizing components of a Lower-Layer Split Radio Access Network (RAN) are provided. In one example, a RAN includes a first Distributed Unit (DU) having: a containerized Cell Site Router (cCSR) that routes user data, control data, or both between the first DU, Radio Units (RUs) of the RAN; and a timing Network Interface Card (NIC) connected to a Global Navigation Satellite System (GNSS) receiver, by which an internal clock of the timing NIC is set. A first RU and a second DU, both connected to the timing NIC of first DU, synchronize their internal clocks to that of the timing NIC using timing information received from the timing NIC.
