tdd slot ✓ Restrictions in ULDLflexible slot and symbol configuration

To configure the downlink signal in this slot pattern, two separate DL-SCHs will be needed to represent two different channel configurations tdd slot,TDD Slot Configuration pattern DDDSU Special Slot Configuration 10D+2G+2U UL-DL configuration

TDD allows uplink and downlink to use the entire frequency spectrum, but in different time slots Time is divided up into short slots tdd slot,Slot Format indicates how each of symbols within a single slot is used It defines which symbols are used for uplink and which symbols are used for downlink

tdd slot,Thus, by changing the TDD slot structure and allocating UL slots for SRS, the gNB can change the period of CSI measurements As shown in Figure 1c, in theory,
