* Based on 2x20 MHz FDD band allocation and 4x4 MIMO. Latency is based on a 32-bit Return Trip Transmission (RTT).VoIP capacity is dependent upon the feature set enabled and network load.
• Combines the best aspects of CDMACDMA,, TDMTDM,, andand OFDM [OFDM [and Layer Superposed (LS)and Layer Superposed (LS)--OFDMOFDM]] into a single air interface using sophisticated control and signaling mechanisms and advanced antenna techniques:− Multiple Input Multiple Output (MIMO), Space Division Multiple Access (SDMA) and Beamforming− Channel Bandwidths: Between 1.25 MHz1.25 MHz and 20 MHz20 MHz, using incremental channel bandwidth
allocations of around 150 kHz
• Will deliver ultra-high fixed, portable and mobile broadband performance*:− Forward link: up to 288 Mbpsup to 288 Mbps while mobile while mobile − Reverse link: up to 75 Mbpsup to 75 Mbps while mobile while mobile − Average network latency: less than less than 16 msec16 msec− Voice over IP (VoIP): up to 1000 simultaneous usersup to 1000 simultaneous users while mobile while mobile
• Will enable the convergence of IP-based voice, broadband data, multimedia, information technology, entertainment and consumer electronic services
• Commercial availability is expected in midmid--20092009

Salient Features of OFDMA Salient Features of OFDMA (compared to CDMA)(compared to CDMA)
In-cell Downlink Orthogonality - No SINR “ceiling” in high SINR regions• No self-interference as in CDMA• Lower complexity than CDMA +IC (interference cancellation)
Orthogonal uplink provides low-complexity spectral efficiency gains• CDMA requires Total Interference Cancellation (TIC) to achieve similar UL performance (higher
complexity)
Enables dynamic scheduling in both time and frequency• Allows for frequency selective scheduling gain• DS-CDMA only schedules vs. time
Enables simple cell-edge interference-mitigation methods
Reduced MIMO complexity for large number of antennas (≥ 4)
Broadcast services benefits• OFDM allows for non-coherent over-the-air combining from different BTSs rather than interference• DS-CDMA requires Minimum Mean Square Error (MMSE) combining or equalization of multiple NodeBs
at the UE to achieve similar benefits (higher complexity)
Intrinsic scalability for a wide range of bandwidths/link budgets/data rates
Higher scheduling burden than DS-CDMA
No autonomous transmission unlike DS-CDMA
Higher PAR on the Uplink
