Distributed Antenna Systems for Multi-Operator Networks

摘要

A mechanism is provided for controlling the sample rate and frequency shift of a digital signal in a multi-operator network. The method is performed by a network node. The method includes obtaining a frequency difference and a phase difference between two clock domains. One of the clock domains is associated with a radio access network of a network operator of the multi-operator network, and the other of the clock domains is associated with a distributed antenna system in the multi-operator network. The method includes controlling a sample rate conversion of a digital signal between two clock domains using a phase difference. Digital signals are communicated between the radio access network and the distributed antenna system. The method includes controlling a frequency shift of a digital signal using the frequency difference.
