(2)Frame Structure(refer to 38.211/38.212/38.213/38.331)
**TS38.331 also specified: only 15/30K is supported for FR1 and only 60/120K is supported for FR2. It shall have no impact if 60K is implemented for FR1.
additional parameter:
l nrMu: u in above table, related to nrScs
l nrCp: NR cyclic prefix, extended only supported for 60K scs. It should be NORMAL only.
**Constant may be useful:
l nrTc: as above
l nrTs: as above
l nrK: = 64
**Time domain structure
More constants:
l nrSubfPerRf: = 10
l nrSlotPerSubf: as defined in above table
l nrSlotPerRf: = nrSlotPerSubf * nrSubfPerRf
l nrSymbPerSlot: as defined in above table
l nrSymbPerSubf: = nrSymbPerSlot * nrSlotPerSubf
l nrSymbPerRf: =nrSymbPerSlot * nrSlotPerRf
**Slot Format
Since slot formats for extended CP is not defined yet, so nrCp should be NORMAL.
So following table is only used for SFI (DCI Format 2_0)? --->YES, table 4.3.2-3 is only applicable for DCI 2-0
Option 46~53 are symmetric.
Option46: DL:UL=5:1
Option47: DL:UL=2:4
Option48: DL:UL=1:5
Option49: DL:UL=4:1
Option50: DL:UL=2:3
Option51: DL:UL=1:4
Option52: DL:UL=1:1
Option53: DL:UL=2:1
It's easy to understand for TDD mode, but for FDD mode, what's the slot configuration?
FDD---> only D, only U, D+X, U+X
TDD--->all formats
Slot configuration in 38.213 Section 11.1:
1、ServingCellConfigCommon 里有ul-dl-config-common
2、ServingCellConfig里有ul-dl-config-dedicated以及slotFormatIndicator定义
All contained within RRCReconfiguration---CellGroupConfig---spCellConfig or sCellToAddModList
TDD ONLY
SFI indication in DCI Format 2-0
Slot format indication x in DCI 2-0 ---> slotFormatCombinationId in SlotFormatCombinationsPerCell ---> slotFormats determines the slot formats for consecutive slots
Tdd-ul-dl-config and DCI 2-0(SFI): interpretation of D/X/U, as defined in 38.213 11.1
For simplicity, user can choose between tdd-ul-dl-config and dci 2-0 for TDD
and for FDD,available option is NA/dci 2-0 where NA means no dci 2-0.
Additional parameters for tdd-ul-dl-config(TDD only):
For both tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationCommon2:
l nrRefScs: reference subcarrier spacing
l nrDlUlTxPeriod: periodicity of dl-ul pattern, ENUMERATED {ms0p5, ms0p625, ms1, ms1p25, ms2, ms2p5, ms5, ms10}
l nrNumDlSlots:
l nrNumDlSymbs:
l nrNumUlSlots:
l nrNumUlSymbs:
nrNumDlSlots D slots, followed by nrNumDlSymbs D symbols, followed by n X symbols, followed by nrNumUlSymbs U symbols, and followed by nrNumUlSlots U slots.
Additional parameters for dci 2-0:
l nrRefScs: reference subcarrier spacing for TDD or FDD DL
l nrRefScs2: reference subcarrier spacing for FDD UL
l nrSlotFormats: list of INTEGER (0..255) which is the slot format configuration in table 4.3.2-3 of 38.211, max length is 256
Dci 2-0(type-3 css) settings:
