Automatic Repeat reQuest ACKnowlegement, hybrid automatic repeat-request confirmation) information and SR
(Scheduling Request, scheduling request) transmission is simultaneously when occurring, how by HARQ-ACK feedback information and SR simultaneously into
There are no complete schemes for row transmission.
In current 5G NR system, when HARQ-ACK is in PUCCH (the Physical Uplink Control of 5G NR
CHannel, Physical Uplink Control Channel) when transmitting on format 0, then use CAZAC (Const Amplitude Zero
Auto-Corelation, permanent envelope zero auto-correlation sequence) transmitted, by different cyclic shift cyclic shift come
Indicate different feedback information states, as shown in Table 1 and Table 2, the mapping of HARQ-ACK state to cyclic shift is initial by one
Cyclic shift CinitalAnd the mapping relations of table 1 or table 2 determine.When HARQ-ACK and SR is on PUCCH format 0
When multiplexing transmission, when SR is negative (negative), HARQ-ACK in the way of the foregoing description (Tables 1 and 2) in HARQ-
It is transmitted in ACK resource, when SR is positive (positive), HARQ-ACK then uses identical PRB (Physical
Resource Block, Physical Resource Block) it transmits in other cyclic shifts in resource, SR is that timing HARQ-ACK state arrives
The mapping of cyclic shift shifts C by initial cycleinitalAnd the mapping relations of table 3 or table 4 determine.
| HARQ-ACK | NACK | ACK |
| Cyclic shift | Cinital | (Cinital+6)mod12 |
Table 1
Table 2
| HARQ-ACK | NACK | ACK |

In 5G NR, the PUCCH transmission of format 0 indicates different control letters using different cyclic shifts
Breath state, and PUCCH format 1 carries out sequence spread spectrum after being modulated to a symbol using HARQ-ACK feedback information again
Mode transmitted, cyclic shift be used for multi-user multiplexing.When HARQ-ACK is transmitted and SR using PUCCH format 1
When being configured to transmit using PUCCH format 0, if HARQ-ACK and the transmission time of positive positive SR there are Chong Die,
It can not be whether there is by the method for similar PUCCH format 0 by using different cyclic shift set to distinguish
Positive SR, and as HARQ-ACK and PUCCH format used in SR difference, it also can not be by the corresponding money of SR
HARQ-ACK is transmitted on source to carry out implied expression there are positive SR.
