Channel Coding for the Control Plane in Broadcast Networks

This paper considers different channel coding techniques suitable for the control plane signals that will be required for some of the services enabled by the ATSC 3.0 Broadcast Core Network (BCN). Short packet and variable code rates are necessary for control plane communications. The suggested techniques are included in the 5G New Radio (NR) and IEEE 802.11 standards. LDPC and CRC-aided (CA) Polar for 5G NR, while Convolution Codes are the main solution for WLAN communications. On the one hand, the study comprises a discussion on the impact of the technical solutions into the core network architectural aspects. On the other hand, the reliability performance of the candidates is evaluated under the Additive White Gaussian Noise Channel (AWGN) for different code rates. The results show that 5G NR CA-Polar is the best candidate.
