Very diverse and sometimes extreme requirements in the 5G mobile and IoT services pose significant challenges to wireless backhaul networks. Particularly, their edge, namely fronthaul(FH), has to be high-capacity, low-latency, reliable and flexible than ever before. To fulfill such 5G/IoT FH demands, some ‘overloading’ techniques to enable much better utilization of the FH infrastructure are indispensable. In this talk, recent advancements on the overloading techniques will be introduced such as including; a low-latency space-time compression technique for massive MIMO RF waveforms for the FH bandwidth efficiency, a signal detection technique for the overloaded FH in massive IoT scenarios, and a latency-aware packet-based transport technique for the FH flexibility.
