1024QAM
1024 Quadrature Amplitude Modulation
Extreme modulation order introduced in Rel-17 mapping 10 bits per symbol for dense small cell environments.
Technical Explanation
Introduced in 3GPP Release 17 for FR1 downlink, 1024QAM packs 10 bits per symbol into a massive 1024-point constellation. It achieves a 25% peak rate enhancement over 256QAM, intended for fixed wireless access (FWA) and dense indoor small cells with pristine line-of-sight conditions (>30 dB SINR).
Key Functions
- Encodes 10 bits per complex modulation symbol
- Provides 25% peak throughput gain over 256QAM in FR1
- Designed for Fixed Wireless Access (FWA) and high-density indoor microcells
