It is secondary to repeat to transmit；When Y is less than X, above-mentioned X repeats transmission and is divided into Y grouping, above-mentioned Y SRI information difference by pre-defined rule
Applied to Y grouping for repeating transmission；When Y is equal to 1, then repetition transmission each of the spatial relationship for X times repeats to pass
It is defeated.For example, when PUSCH iterative transfer times X be greater than 1, and Y be equal to 1 when, i.e. SRI information aggregate only includes 1 SRI information,
Then the SRI information repeats to transmit for each of repetition transmission of X PUSCH.
Pre-defined rule comprises at least one of the following: rule 1: being followed successively by number needed for each grouping distributes by transmission number is repeated
Number is transmitted in the repetition of amount；Rule 2: transmission number is repeated until distributing for each grouping distribution in turn by transmission number is repeated
Finish.
Each grouping is required amount of to be repeated transmission to number the method for determination to include: each grouping when X can be divided exactly by Y
Required repetition transmission quantity is X/Y.When X cannot be divided exactly by Y, packet numbering is lesserThe repetition of a grouping
Transmitting number quantity isNumber quantity is transmitted in the repetition of remaining groupingAlternatively, when X cannot be whole by Y
Except when, packet numbering is biggishNumber quantity is transmitted in the repetition of a groupingThe weight of remaining grouping
Transmission number quantity is againWhereinFor downward floor operation.
Assuming that X=6, Y=2, pre-defined rule is required amount of heavy to be followed successively by each grouping distribution by repetition transmission number
When multiple transmission number, grouping has 2, and two groupings all include 3 repetition transmission numbers, and number lesser 3 in X are distributed to
Numbered packets are transmitted in 1st repetition, and number biggish 3 in X are distributed to the 2nd repetition transmission numbered packets.3 times weigh
Multiple transmission uses identical spatial parameter information (such as SRI information), and rear 3 repetitions transmission uses identical spatial parameter information.
Assuming that X=6, Y=2, it is that each grouping distribution repeats transmission number that pre-defined rule is by transmission number is repeated in turn
When being assigned, grouping has 2, and two groupings all transmit number comprising 3 repetitions, and the number in X is 3 points of even number
Numbered packets are transmitted in the 1st repetition of dispensing, and the number in X is that 3 of odd number distribute to the 2nd repetition transmission numbered packets.I.e.
Repeating transmission number is even number using identical spatial parameter information, and repeating transmission number is odd number using identical space
Parameter information.
Assuming that X=7 (including X_0, X_1 ..., X_6), Y=4 (including Y_0, Y_1 ..., Y_3), pre-defined rule be by
When repeating transmission number and being followed successively by that each grouping distribution is required amount of to repeat transmission number, being grouped has 4, and packet numbering is smaller
3 groupings (including Y_0, Y_1, Y_2) include 2 repetition transmission number, i.e., Y_0 group include X_0 and X_1, Y_1 group include X_
2 and X_3, Y_2 group include X_4 and X_5, and biggish 1 grouping of packet numbering includes 1 repetition transmission number, i.e. Y_3 group includes
X_6。
Work as X=2, when Y=1, repeats transmission and belongs to same group for X times, at this point, each repetition for repeating transmission for X time is transmitted all
Use unique SRI information.
MAC CE or DCI include that information is used to indicate the one kind for applying rule 1 or rule 2.MAC CE or DCI include information
Y SRI information of activation is used to indicate for multiple sequences repeated when transmitting.For example, as Y=2, one of R bit
It is used to indicate that Y=2 SRI information of activation for multiple sequences repeated when transmitting.For example, 1 bit value is that 0 expression is suitable
Sequence, value are 1 expression backward.
To the PUSCH transmission of the configuration authorization of Class1, number of repetition X=X0；The PUSCH of the configuration authorization of type 2 is passed
Defeated and dynamic authorization PUSCH transmission, when indicating the number of repetition X1 of scheduled transmission in DCI, number of repetition X=X1,
Otherwise, number of repetition X=X0.SRI information indicates at least one SRS resource, is used to indicate the money of SRS referenced by single transmission

In addition, the value that some bit numbers are not particularly described in above-mentioned example is reserved bit.By taking table 4 as an example, when SRS is provided
When SRS resource quantity in the set of source is 4, if Y maximum is 2, the domain SRI has 0-18 to have 19 kinds of information, the bit needed altogether
Number is 5.5 bits can indicate 32 kinds of information altogether, therefore the biggish 13 kinds of values of value are exactly to retain.
Table 6 is the citing in the domain SRI of codebook-based PUSCH.Wherein bit value is { 0；1 } the 1st and the 2nd is indicated
SRI information is the SRS resource 0,1 in SRS resource set respectively.
The SRI information aggregate of the codebook-based PUSCH transmission of table 6
| Bitfield value | SRS resource instruction, NSRS=2 |
| 0 | 0 |
| 1 | 1 |
| 2 | 0；1 |

In one embodiment, Y spatial parameter information is by the domain SRI and antenna port domain joint instructions.Y spatial parameter letter
Breath includes at least one of by the domain SRI and antenna port domain joint instructions: some or all of antenna port domain bit and SRI
Some or all of domain bit combination indicates Y spatial parameter information；The domain SRI indicates first in Y spatial parameter information
Spatial parameter information, antenna port domain indicate remaining Y-1 spatial parameter information.
The transmission sent is repeated, the relatively high situation of performance requirement is generally used for, uses multi-user's multiple-input, multiple-output at this time
The necessity of (Multi-User Multiple-Input Multiple-Output, MU-MIMO) is not very strong.Assuming that repeating
Transmission is served only for single user multiple-input, multiple-output (Single-User Multiple-Input Multiple-Output, SU-MIMO),
Then the antenna port domain in DCI can partly or entirely be used to indicate part SRI information aggregate.One of specific following manner:
The overhead bit in the domain mode 3:SRI is identical as only the 1st expense of SRI information of instruction, and due to including in mode 2
The combination of Y > 1 and the spare bits for causing the expense in the domain SRI to become larger are placed on the instruction of antenna port domain.
Antenna port domain is designed for SU/MU-MIMO transmission originally, and the amount of bits in the domain is according to transfer pre-coding
The factors such as whether (transform precoder) enabled, the time-domain symbol quantity of DMRS type and DMRS determine, minimum 2
Bit, maximum 5 bits.And from the description above it is found that mode 2 only has 0,1 or 2 ratios to the expansion bit demand of SRI information aggregate
It is special.When number of repetition, which is greater than 1 and/or different beam diversity quantity Y, is greater than 1, antenna port domain is not used in instruction MU-MIMO
Information, then it is predetermined when information indicated by antenna port domain.When port number is 1, then port 0 is fixed as；When
When port number is 2, then port 0,1 is fixed as；When port number is 2, then port 0,1,2 is fixed as；When port number is 3
When, then it is fixed as port 0,1,2,3.And so on, since port 0, until being assigned to enough port numbers.In addition,
Front-load (by front position) symbolic number can also be determined by the quantity of port number, DMRS CDM group according to port number.
For example, when DMRS type is 1, the quantity of DMRS CDM group is 2, when DMRS port number is less than 4 when transfer pre-coding is enabled,
Front-load symbolic number is 1, and DMRS port number be greater than or equal to 4 when, front-load symbolic number is 2.
The amount of bits in antenna port domain is determined by least one of following parameter: whether transfer pre-coding enables, DMRS
Type, the maximum symbol quantity of DMRS, order (rank) numerical value.According to different situations, the amount of bits in antenna port domain be can be
2, one of 3,4,5.
Therefore antenna port domain can at least provide 2 bit informations for expanding the domain SRI.For example, the domain SRI is in instruction Y=1
SRI information when need 4 bits, need 6 bits when indicating the SRI information of Y=4, so much 2 remaining bit antenna ports
Domain instruction.Such as low 2 bit (or 2 bits of LSB) or high 2 bit (or 2 bits of MSB) in antenna port domain, as a high position
2 bits and 4 bits in the domain SRI be unified into 6 bit informations, the SRI for the various situations in method described in mode 2 believes
Breath set instruction.For another example, the domain SRI needs 4 bits when indicating the SRI information of Y=1, needs when indicating the SRI information of Y=4
5 bits, so much 1 remaining bit are indicated with antenna port domain.
The domain mode 4:SRI indicates the 1st SRI information, and antenna port domain indicates the 2nd SRI information.
When the bit number in the domain SRI be less than or equal to antenna port domain bit number when, then the SRI information in antenna port domain with
The SRI information in the domain SRI has identical expense, and identical bit value indicates identical SRI information.
When the bit number in the domain SRI is greater than the bit number in antenna port domain, then day is determined using at least one following rule
Line end mouth domain indicates the mode of the 2nd SRI information:
The SRI information of antenna port domain instruction is the subset of the SRI information in the domain SRI；
Indicated SRS in the SRI information of SRS resource quantity and the domain SRI that the SRI information of antenna port domain instruction includes
Resource quantity is identical.
The selectable value quantity for the SRI information that can be indicated the antenna port domain of majority of case using the above rule is compressed
To less than or equal to 4.By taking table 2 as an example, work as NSRSWhen the SRS resource quantity of the SRI information instruction in the domain=4, SRI is 1, antenna end
The selectable value of the SRI information of mouth domain instruction is 0-4 (being shown in Table 2 the right two to arrange), altogether 4 kinds of situations, it is only necessary to the 2 of antenna port domain
Bit information.Work as NSRSWhen the SRS resource quantity of the SRI information instruction in the domain=3, SRI is 2, the instruction of antenna port domain
The selectable value of SRI information is 3-5 (be shown in Table 2 among two arrange), altogether 3 kinds of situations, it is only necessary to which 2 bit informations in antenna port domain are
It can.
Work as NSRSWhen the SRS resource quantity of the SRI information instruction in the domain=4, SRI is 2,6 kinds of situations, the same day are indicated in table 2
When the amount of bits in line end mouth domain is less than 3, then the SRI information content that antenna port domain indicates is determined as 4 according to following combination
A: [0,1], [0,2], [1,3], [2,3] respectively correspond the bit value 4,5,8,9 that the right two of table 2 arranges.
Since instruction expense of the mode 4 to the 2nd SRI information is smaller, the instruction of antenna port described in which
2nd SRI information can also indicate in the extended bit of the domain SRI.By taking table 2 as an example, work as NSRSThe SRI information in the domain=4, SRI indicates
SRS resource quantity when being 1, the selectable value of the SRI information of antenna port domain instruction is 0-4 (be shown in Table 2 the right two arrange), altogether 4
Kind situation, it is only necessary to 2 bit informations in antenna port domain.This dibit information can be the domain SRI extended bit, i.e. SRI
Domain includes 6 bit informations, wherein 4 bits indicate the 1st SRI information, in addition 2 bits indicate the 2nd SRI information.
Which can also further expand the case where being greater than 2 for Y, for example, the domain SRI includes 8 bit informations, wherein 4
Bit indicates the 1st SRI information, and 2 bits indicate the 2nd SRI information, also.2 bits indicate the 3rd SRI information.
