物理下行信道3个:PDCCH,PDSCH,PBCH
下行支持的调制:QPSK, 16QAM, 64QAM, and 256QAM
上行信道3个:PUCCH,PUSCH,PRACH
上行支持的调制:1.QPSK, 16QAM, 64QAM and 256QAM for OFDM with a CP
2.对于处在小区边缘的UE π/2-BPSK, QPSK, 16QAM, 64QAM and 256QAM for DFT-s-OFDM with a CP
参考信号:CSI RS,SRS,DMRS,PTRS
同步信号:SS
The physical channels defined in the downlink are:
- the Physical Downlink Shared Channel (PDSCH),
- the Physical Downlink Control Channel (PDCCH),
- the Physical Broadcast Channel (PBCH),
The physical channels defined in the uplink are:
- the Physical Random Access Channel (PRACH),
- the Physical Uplink Shared Channel (PUSCH),
- and the Physical Uplink Control Channel (PUCCH).
In addition, signals are defined as reference signals, primary and secondary synchronization signals.
The modulation schemes supported are
- in the downlink, QPSK, 16QAM, 64QAM, and 256QAM,
- in the uplink, QPSK, 16QAM, 64QAM and 256QAM for OFDM with a CP and π/2-BPSK, QPSK, 16QAM, 64QAM and 256QAM for DFT-s-OFDM with a CP
