Query: Random NOMA With Cross-Slot Successive Interference Cancellation Packet
  Recovery   Conventional power-domain non-orthogonal multiple access (NOMA) relies on
precise power control, which requires real-time channel state information at
transmitters. This requirement severely limits its application to future
wireless communication systems. To address this problem, we consider NOMA
without power allocation, where we exploit the random channel fading and
opportunistically perform successive interference cancellation (SIC) detection.
To mitigate the multi-user interference, we propose a random NOMA where users
randomly transmit their data packets with a certain probability. Then a
cross-slot SIC packet recovery scheme is proposed to recover transmitted data
packets. We model the cross-slot SIC packet recovery as a Markov process, and
provide a throughput analysis, based on which the sum rate is maximized by
jointly optimizing the transmission probability and the encoding rate of users.
