specific Embodiment 1
[0102]In this embodiment, the Semi-Static UL-DL configuration takes M slots as a cycle, and the symbols of each slot can be configured. Each slot can include DL symbols, UL symbols, and unknown symbols. Different slots in the M slots There may be different configurations.
[0103] Such as image 3 As shown, the UL-DL configuration cycle is 10 slots, the first three slots are DL symbols, the fourth slot contains the switching point from DL to UL, and the subsequent slots are all UL symbols, as shown in the figure Use D to represent the DL symbol, X to represent the unknown symbol, and U to represent the UL symbol. The slot for sending the SR may be notified to the UE through bitmap1 of a slot-level (Slot-level), that is, the first bitmap. Among them, the number of bits in bitmap1 is related to the UL-DL configuration, and the length S of bitmap1 can take the following two values but is not limited to the following values:
[0104] (1) The length S of bitmap1 is equal to th...
specific Embodiment 2
[0125] In this embodiment, Semi-Static UL-DL configuration can configure the symbols of each slot, and each slot can include DL symbols, UL symbols and unknown symbols.
[0126] Such as Figure 4 As shown, a slot includes 14 symbols, the first four symbols are DL symbols, the fifth-seventh symbols are unknown symbols, and the last seven symbols are all UL symbols. In the figure, D represents DL symbol and X represents unknown symbol, U to represent the UL symbol.
[0127] Which symbols in the slot are used to send the SR can be indicated through Symbol-level bitmap3, that is, the third bitmap, that is, SR transmission occassion. Among them, the length L of bitmap3 can take one or more of the following values:
[0128] (1) The length L of bitmap3 is equal to the number K of symbols included in a time slot;
[0129] (2) The length L of bitmap3 is equal to the number k of uplink symbols and / or unknown symbols included in a time slot;
[0130] (3) The length L of bitmap3 is eq...
