Allocating a physical radio resource for a non-guaranteed bit rate (non-GBR) bearer in a distributed communications system (DCS) is disclosed. More specifically, the method enables a radio circuit in a network node to divide the physical radio resource among a number of non-GBR quality-of-service (QoS) class identifiers (QCIs) based on a number of predetermined scheduling ratios, respectively. The radio circuit can be configured to dynamically rebalance physical radio resource allocation among the non-GBR QCIs such that the network node can maintain the predetermined scheduling ratios or respond to a reconfiguration of the predetermined scheduling ratios among the non-GBR QCIs. As a result, a network operator(s) can dynamically adjust physical radio resource allocation among the non-GBR QCIs based on, for example, subscribers' network usage and plan limits, thus making it possible for the network operator(s) to customize QoS configuration to enable differentiated non-GBR services.
