Description
Technical field
The present invention relates to field of communication technology more particularly to the transmission methods and device of a kind of Downlink Control Information.
Background technique
In LTE TDD system, the HARQ-ACK of the data of multiple downlink subframes may be carried out in the same sub-frame of uplink
Feedback can be to Downlink Control Information DCI (Downlink Control using dynamic HARQ-ACK code book
Information it) is counted, and then determines the HARQ-ACK bit number of feedback.One physical down link of DCI scheduling is total
Enjoying channel PDSCH may include a transmission block TB (Transport Block), it is also possible to include 2 TB, respectively correspond 1
HARQ-ACK bit and 2 HARQ-ACK bits.In LTE TDD system, when certain downlink DCI in HARQ feedback window lose
When mistake, UE may mistakenly feed back HARQ-ACK, in order to solve this problem, downlink distribution index DAI be introduced in DCI
(Downlink Assignment Index), for being counted to DCI with inform UE in HARQ feedback window how many
Subframe includes downlink transfer.Wherein comprising counting DAI (Counter DAI, abbreviation C-DAI) and total DAI in the domain DAI of DCI
(Total DAI, abbreviation T-DAI) is ranked up DCI by counting DAI, the quantity of DCI is determined by total DAI.Wherein, it counts
Number DAI and total DAI is indicated with 2 bits, and the DAI definition and indicating mode in agreement are as shown in table 1.
Table 1
It is multiplexed identical 2 bit DAI's by way of mould 4 when counting numerical value expressed by DAI and total DAI and being more than 4
State is indicated that therefore, what UE can judge to indicate at this time according to the DAI value received is which of multiple numerical value
Value, such as UE are received and are counted DAI=1 and total DAI=1, and UE has been received that 4 DCI before the data packet, then recognizes
It is 5 to count the numerical value of DAI and total DAI instruction at this time.
As shown in Figure 1, the schematic diagram of the descending scheduling time instruction for DCI, the unit of K0, K1 are all time slots, K0 is indicated
The time interval of physical down link sharing channel PDSCH and physical downlink control channel PDCCH (DCI), K1 are indicated
The time interval at HARQ-ACK feedback moment and PDSCH.
In (New Radio, NR) system of newly eating dishes without rice or wine, due to that can there is multiple PDCCH to monitor in a downlink subframe
Moment, and NR system supports the DAI for leading to LTE system across timeslot scheduling is defined can not be completely suitable for NR system, therefore
In NR system, by DAI define in { cell, subframe } it is right to { cell, PDCCH monitor moment } has been substituted for, such as 2 institute of table
Show, is DAI definition and the indicating mode in NR system.
Table 2
In NR system, for the cell of the same physical uplink control channel PUCCH group, PDCCH monitors the moment
Collection be combined into each cell PDCCH and monitor moment union of sets collection.
As shown in Fig. 2, cell 0 is identical with the configuration of cell 1, i.e., base station is by the value that high-level signaling configures cell K1
{ 1,2,3,4,5,6,7,8 }, the value of K0 are { 0,1,2 }.The each time slot of PDCCH is monitored once, positioned at first 2 of each slot
OFDM symbol.The PDSCH of DCI scheduling only includes a TB, and cell does not configure code block group CBG (Code Block Group) biography
Defeated, corresponding each PDSCH only needs to feed back HARQ-ACK with 1 bit.
Since NR is introduced across timeslot scheduling, cell 1 scheduled the PDSCH of a time slot n+1 in time slot n-1, the PDSCH
It feeds back in time slot n+2, is defined according to the DAI in current NR system, which can contribute in DAI, as shown in table 3.
Table 3
PDCCH monitors the OFDM symbol 0 ... for corresponding to time slot n-10 at the moment 0, and PDCCH monitors the corresponding time slot n-3 of moment 7
OFDM symbol 0, PDCCH monitors the OFDM symbol 0 of the corresponding time slot n-2 of moment 8, and PDCCH monitors the corresponding time slot n-1's of moment 9
OFDM symbol 0.
It is needed according to total DAI=3 that the PDCCH monitoring moment receives, UE to 3 bit feedback HARQ-ACK, and actually
Since cell 1 scheduled in time slot n-1 the PDSCH of a time slot n+1, which feeds back in time slot n+2, can't be in time slot n
It is fed back, therefore only needs to carry out cell 0 in the PDSCH that time slot n-2 is dispatched in the time slot n-1 PDSCH dispatched and cell 1
Feedback, that is, need 2 HARQ-ACK bits.
Cause the DCI institute arrived in identical PDCCH monitoring reception right across timeslot scheduling it can be seen that NR system is introduced
The HARQ-ACK answered may be transmitted in different HARQ feedback windows, this allows for determining according to DAI in current NR system
Justice will cause the waste of uplink resource.
Summary of the invention

OFDM symbol.The PDSCH of DCI scheduling only includes a TB, and cell does not configure CBG transmission, and corresponding each PDSCH only needs to use
1 bit feedback HARQ-ACK.For the HARQ-ACK of time slot n feedback, base station can dispatch a time slot n-8's in time slot n-10
The PDSCH of PDSCH (K0=2), time slot n-8 to time slot n-1 can be fed back in time slot n, therefore when the monitoring section of PDCCH is
Gap n-10 to time slot n-1.
The monitoring moment of PDCCH takes union for the monitoring moment of the PDCCH of cell 0 PDCCH for monitoring moment and cell 1,
That is the OFDM symbol 0 of time slot n-10 to time slot n-1.PDCCH monitors the OFDM symbol 0 ... for corresponding to time slot n-10 at the moment 0,
PDCCH monitors the OFDM symbol 0 of the corresponding n-2 of moment 8, and PDCCH monitors the OFDM symbol 0 of the corresponding n-1 of moment 9.
Cell 0 receives a DCI instruction SPS release in time slot n-6, and receiving a DCI in time slot n-5 scheduled time slot n-
5 PDSCH, receiving a DCI in time slot n-4 scheduled the PDSCH of time slot n-4.
Cell 1, which receives a DCI in time slot n-6, scheduled the PDSCH of time slot n-4.A DCI tune is received in time slot n-5
The PDSCH of time slot n-3 is spent.Receiving a DCI in time slot n-1 scheduled the PDSCH of time slot n+1.
DAI definition according to the present invention, the value condition of DAI, as shown in table 5.
Table 5
PDCCH monitors the corresponding time slot n-6 of moment 4, shares 2 DCI at this time, and total DAI is that 2, the PDCCH monitoring moment 5 is corresponding
Time slot n-5 shares 2 DCI at this time, in addition the PDCCH of front monitors the DCI quantity at moment, when total DAI is that 4, PDCCH is monitored
6 corresponding time slot n-4 are carved, share 1 DCI at this time, in addition the PDCCH of front monitors the DCI quantity at moment totally 5 DCI, according to table
2, total DAI are 1.The DAI is the last one DAI that UE is arrived in time slot n feedback reception, and UE is determined according to total DAI in time slot n
The bit number for feeding back HARQ-ACK is 5 bits.
