Any one of or at least two combinations.
Point situation is introduced first information domain as follows below:
The first situation, first information domain are RV information field, and at this moment RV information field can pass through 2 bit indication modulation orders
Number.
For example, terminal can be passed in a PUSCH after the DCI for receiving base station transmission by the instruction of DCI
Defeated CSI, wherein do not include UL-SCH Data Transmission Content in PUSCH.It include the RV information field of 2 bits in DCI, base station can be with
The order of modulation used by being multiplexed this 2 bit indication terminal transmission CSI, specific indicating mode can be as shown in table 1.
Table 1
In table 1, each bit in the RV information field of 2 bits can have two kinds of bit status, i.e. bit status 1 and ratio
Special state 0 can indicate different order of modulation by the different conditions of the RV information field of 2 bits.
Therefore, in table 1, when the state of RV information field is 00, it can indicate that the order of modulation of CSI is 2, corresponding CSI's
Modulation system can be QPSK；When the state of RV information field is 01, it can indicate that the order of modulation of CSI is 4, corresponding CSI's
Modulation system can be 16 quadrature amplitude modulations (Quadrature Amplitude Modulation, QAM)；RV information field
When state is 10, it can indicate that the order of modulation of CSI is 6, the modulation system of corresponding CSI can be 64QAM；RV information field
When state is 11, it can indicate that the order of modulation of CSI is 8, the modulation system of corresponding CSI can be 256QAM, or for
It does not support to carry out the terminal that 256QAM transmits CSI, the state 11 of RV information field can retain, i.e., do not indicate any information.
It should be noted that the content in table 1 is only for example, it is not excluded that define other bit status combinations and modulation order
Several correspondence situations.
Generally speaking, when terminal determines that DCI transmits aperiodic CSI on PUSCH and do not have data for instruction, terminal can
To determine order of modulation used when sending aperiodic CSI on PUSCH by the RV information field in DCI.
Second situation, first information domain are HARQ process number information field, then HARQ process number information field can by 3 or
The order of modulation of 4 bit indication CSI, in this case, the first two bit in 3 or 4 bits that can include by HARQ
The different order of modulation of state instruction.
For example, terminal can be passed in a PUSCH after the DCI for receiving base station transmission by the instruction of DCI
Defeated CSI, wherein do not include UL-SCH Data Transmission Content in PUSCH.It include the HARQ process number information field of 4 bits in DCI,
Base station used order of modulation when can be by being multiplexed this 4 bit indication terminal transmission CSI, specific indicating mode can be such as table
Shown in 2.
Table 2
In table 2, x expression can be arbitrary bit status, i.e. x can be bit status 1 or bit status 0.Example
Such as, when the state of HARQ process number information field is 1000, terminal can transmit CSI by the modulation system of 64QAM, work as HARQ
When the state of process number information field is 0110, terminal can transmit CSI by the modulation system of 16QAM, when HARQ process number is believed
When the state for ceasing domain is 1101, terminal can transmit CSI etc. by the modulation system of 256QAM.
Therefore, in table 2, when the state of the first two bit in 4 bits of HARQ process number information field is 00, can refer to
The order of modulation for showing CSI is 2；When the state of the first two bit in 4 bits of HARQ process number information field is 01, it can refer to
The order of modulation for showing CSI is 4；When the state of the first two bit in 4 bits of HARQ process number information field is 10, it can refer to
The order of modulation for showing CSI is 6；When the state of the first two bit in 4 bits of HARQ process number information field is 11, it can refer to
Show the order of modulation 8 of CSI, or the terminal for not supporting progress 256QAM transmission CSI, the state of HARQ process number information field
11 can retain, i.e., do not indicate any information.
If HARQ process number information field is 3 bits, first bit and second bit in HARQ process number information field
Can serve to indicate that the order of modulation of CSI, and the state of third bit can retain, i.e., no matter the bit shape of third bit
State is 0 or 1, and third bit can not indicate any information；If HARQ process number information field is 4 bits, HARQ
The state of third and fourth bit of process number information field can retain, i.e., no matter any bit in third and fourth bit
Bit status be 0 or 1, third and fourth bit can not indicate any information.It is only for example herein, it is not excluded that definition
The correspondence situation of other bit status combinations and order of modulation.
Generally speaking, when terminal determines DCI to indicate to transmit CSI on PUSCH and do not have data, terminal can pass through
HARQ process number information field in DCI determines and sends the order of modulation that CSI is used on PUSCH.
The third situation, first information domain are NDI information field, then NDI information field passes through 1 bit indication order of modulation.
When NDI information field is 1 bit, the state of NDI information field can be 0 or 1, can indicate respectively the difference of CSI
Order of modulation.
For example, terminal when determining that DCI indicates transmission CSI on PUSCH and do not have data, can pass through 1 in DCI and compare
Special NDI information field, which determines, sends the order of modulation that CSI is used on PUSCH, specific indicating mode can be as shown in table 3.
Table 3
It should be noted that only illustrating in table 3, it is not excluded that other of the state of NDI information field and order of modulation are right
Answer situation, such as when state of NDI information field is 1 corresponding order of modulation is 2.
If the 4th kind of situation, first information domain be RV information field, HARQ process number information field and NDI information field at least
Two combinations, then by y bit indication order of modulation, y is the integer more than or equal to 3 at least two combinations.
That is the first information domain in DCI can be in RV information field, HARQ process number information field and NDI information field any two
The combination or first information domain of item are also possible to RV information field, HARQ process number information field and NDI information field three groups
It closes.
(1), by taking the first information domain in DCI is HARQ process number information field and NDI information field two combinations as an example.
Assuming that HARQ process number information field is 3 bits, NDI information field is 1 bit, then first information domain includes 4 bits, this
Shi Jizhan used order of modulation when can be by being multiplexed this 4 bit indication terminal transmission CSI, specific indicating mode can be with
Referring to table 4.
Table 4
Wherein, the first two bit in HARQ process number information field and the combination of NDI information field can be with all HARQ processes
Number information field, i.e. the first two bit in the HARQ process number information field of 3 bits be as combined the first two bit, HARQ into
The third bit of journey information field and 1 bit of NDI information field can be any bit status, not indicate any information；
Alternatively, 1 bit is NDI in the first two bit in HARQ process number information field and the combination of NDI information field, another bit is
The previous bit of HARQ process number information field, and in third and fourth bit of HARQ process number information field can for appoint
Meaning bit status, does not indicate any information etc..
In practical applications, combined indicating mode is also possible that other similar situation, the embodiment of the present invention are not made
It repeats.
In addition, first information domain is the combination of RV information field and HARQ process number information field or first information domain is RV
The case where combination of information field and NDI information field, may refer to above-mentioned first information domain is that HARQ process number information field and NDI believe
The description when combination in domain is ceased, is also repeated no more in the embodiment of the present invention.
(2), first information domain is also possible to RV information field, HARQ process number information field and NDI information field three combinations.
Assuming that RV information field is 2 bits, HARQ process number information field is 4 bits, and NDI information field is 1 bit, then the first letter
Breath domain can indicate the order of modulation of CSI by the first two bit in 7 bits, and specific indicating mode can be such as 5 institute of table
Show.
Table 5
In table 5, x expression can be arbitrary bit status, i.e. x can be bit status 1 or bit status 0.
For example, terminal can transmit CSI by the modulation system of QPSK when three combined states are 0000101,
When three combined states are 0110001, terminal can transmit CSI by the modulation system of 16QAM, when three combinations
State when being 1100001, terminal can pass through the modulation system of 256QAM and transmit CSI etc..
The position of RV information field, HARQ process number information field and NDI information field in DCI can in any permutation, and base station can
The order of modulation of CSI is indicated with the first two bit by the first information domain obtained after arrangement.
5th kind of situation, first information domain are n-bit information field, wherein n-bit information field can be to be used to indicate CSI
Order of modulation and the information field different from RV information field, HARQ process number information field and NDI information field, n be more than or equal to 2
Integer.
For example, indicating different order of modulation, the first two ratio by the different conditions of the first two bit in n-bit information field
The order of modulation of 00 instruction CSI in special state is 2；01 instruction CSI order of modulation is 4；10 instruction CSI order of modulation be
6；The order of modulation of 11 instruction CSI is 8 or state retains, and does not indicate any information.The first two bit is removed in n-bit information field
Except bit status retain, do not indicate any information.Be only for example herein, it is not excluded that define the combination of other bit status and
The correspondence situation of order of modulation.
For example, base station indicates that UE transmits CSI in a PUSCH by DCI, UL-SCH data are not included in PUSCH
Transferring content.It include n-bit information field in DCI, the modulation order that CSI is used is transmitted by being multiplexed this n-bit instruction terminal in base station
Number, specific indicating mode are as shown in table 6.
Table 6
In table 6, taking n is 5, i.e., first information domain is 5 bit information domains, and x expression can be arbitrary bit status, i.e. x
It can be bit status 1 or bit status 0.For example, terminal passes through when the state in 5 bit information domains is 10000
The modulation system of 64QAM transmits CSI；When the state in 5 bit information domains is 01101, terminal is passed by the modulation system of 16QAM
Defeated CSI；When the state in 5 bit information domains is 11011, terminal transmits CSI by the modulation system of 256QAM.
Generally speaking, when terminal determines DCI to indicate to transmit CSI on PUSCH and do not have data, terminal can pass through
The state of n-bit information field in DCI is determined sends the order of modulation that CSI is used on PUSCH.
