Beyond 4G Beyond 4G


WiMAX Release 1.0 Key Features cont. Adaptive modulation and coding (AMC) with higher order

modulation: QPSK, 16QAM, and 64QAM HARQ for coverage/capacity enhancement Advanced channel coding: CC, CTC2) Connection-based MAC for QoS management 5 QoS categories: UGS, rtPS, ertPS, nrtPS, and BE3) Dynamic resource allocation Power management: sleep mode and idle mode Handover: hard handover and optimized hard handover4) Multicast broadcast service (MBS) Simple Architecture

– BTS with profile C– Smaller number of RAN interfaces

– BTS ASN-GW ( control and data)
