Table 3 Logical channels.

From: Design and Implementation of a Single-Frequency Mesh Network Using OpenAirInterface

Broadcast Control Channel

BCCH

Low bit-rate control channel used by a CH for broadcasting basic Low bit-rate control channel used information to nodes in the cluster.

Common Control Channel

CCCH

Low bit-rate control channel used both during the attachment or association phase of a new node.

Dedicated Control Channel

DCCH

Access-layer signaling information (RLC return channels, RF measurement reporting, traffic measurement reporting, power control, etc.) to the corresponding node.

Dedicated Traffic Channel

DTCH

Variable bit-rate traffic channel with negotiated QoS parameters used by the mesh network to transport data traffic corresponding to a particular flow.
