Query: Coexistence of URLLC and eMBB services in the C-RAN Uplink: An
  Information-Theoretic Study   The performance of orthogonal and non-orthogonal multiple access is studied
for the multiplexing of enhanced Mobile BroadBand (eMBB) and Ultra-Reliable
Low-Latency Communications (URLLC) users in the uplink of a multi-cell Cloud
Radio Access Network (C-RAN) architecture. While eMBB users can operate over
long codewords spread in time and frequency, URLLC users' transmissions are
random and localized in time due to their low-latency requirements. These
requirements also call for decoding of their packets to be carried out at the
edge nodes (ENs), whereas eMBB traffic can leverage the interference management
capabilities of centralized decoding at the cloud. Using information-theoretic
arguments, the performance trade-offs between eMBB and URLLC traffic types are
investigated in terms of rate for the former, and rate, access latency, and
reliability for the latter. The analysis includes non-orthogonal multiple
access (NOMA) with different decoding architectures, such as puncturing and
successive interference cancellation (SIC). The study sheds light into
effective design choices as a function of inter-cell interference,
signal-to-noise ratio levels, and fronthaul capacity constraints.
