Description
Technical field
The present invention relates to communication technical field, particularly to a kind of method of transmission configured information, apparatus and system.
Background technology
Hybrid automatic repeat-request（Hybrid Automatic Repeat reQuest, HARQ）Technology is automatic repetition
Request（Automatic Repeat reQuest, ARQ）Technology and forward error correction（Forward Error Correction,
FEC）The combination of technology.Because HARQ technology can carry out Fast retransmission to the data block of error of transmission, and make full use of mistake
The information that data carries carries out data merged block and decoding.Therefore, as high-speed slender body theory（High Speed
Downlink Packet Access, HSDPA）, High Speed Uplink Packet access（High Speed Uplink Packet
Access, HSUPA）, Long Term Evolution（Long Term Evolution, LTE）All logarithm is supported using HARQ technology etc. system
According to continuous scheduling and transmission.
Distinguish according to retransmitting the moment occurring, HARQ technology can be divided into synchronous HARQ and asynchronous HARQ two species
Type.Wherein, synchronous HARQ refers to a HARQ process（process）Transmission（Retransmit）It is to occur when fixing, due to
In the generation moment of the previously known transmission of receiving terminal, extra signaling consumption is not therefore needed to identify the process of this HARQ process
Number, now the process number of HARQ process can obtain from subframe numbers；Asynchronous HARQ refers to that the transmission of a HARQ process can be sent out
At any time, receiving terminal does not know the generation moment of transmission in advance it is therefore desirable to indicate the process number of HARQ process for life；Its
In, the process number of HARQ process is by system configuration, and each process number represents a different HARQ process.For example, under
Row data transmission procedure, due to employing asynchronous HARQ techniques, accordingly, it would be desirable to indicate scheduled subframe pair in DL grant
The process number of the HARQ process answered.At present, generally adopt bit（bit）Information indicating the process number of HARQ process, for example, when
Divide duplex（Time Division Duplexing, TDD）12 HARQ processes are had in system（Its process number is arranged as 1 in order
~ 12, i.e. process 1 ~ process 12）, using 4 bits, process number can be carried out to HARQ process in TDD system, that is, indicate that a HARQ enters
The process number of journey needs 4 bits.
Generally, in LTE system, for dynamic dispatching business, base station is passed through in Physical Downlink Control Channel（Physical
Downlink Control Channel, PDCCH）One dispatch of middle transmission（grant）Dispatch a data transfer, that is, one
Bar dispatch is dispatched a subframe and is carried out data transmission.With the increase of the evolution data business of technology, many subframe schedulings
The concept of technology is suggested, and can reduce the expense of control signaling.Many subframe schedulings technology refers to descending using one
（Downlink, DL）/ up（Uplink, UL）Grant dispatches N（N>1）The technology that individual subframe carries out data transmission, wherein, N（N
>1）Individual subframe can correspond to a process, or corresponds to N number of independent process respectively.
In many subframe schedulings technology, if using the scheme of the corresponding N number of independent process of N number of subframe, in a grant
Need to comprise the configured information for indicating this N number of HARQ process, but there is presently no the method indicating multiple HARQ processes.If
The indicating means being used using LTE system downlink transfer, that is, adopt bit（bit）Information is indicating the process of HARQ process
Number, then can lead to substantial amounts of signaling consumption.Still with time division duplex（Time Division Duplexing, TDD）As a example system,
It has 12 HARQ processes, because one HARQ process of instruction needs 4 bits it indicates that N number of process then needs 4*N bit,
And in the research to many subframe schedulings technology at present, the value generally >=4 of number of subframes N of same dispatch scheduling,
Calculated with this, be then used for indicating that the signaling consumption of HARQ process is at least 16 bits, considerably increase the expense of signaling；According to
Bitmap（bitmap）Mode, to indicate multiple HARQ processes, equally also results in substantial amounts of signaling consumption, with TDD system is still
Example, it has 12 HARQ processes, then need 12 bits to indicate whether process 1 ~ process 12 is scheduled, if bit successively in order
For " 1 ", position then represents that this bit corresponding HARQ process is scheduled, if bit is " 0 ", represent that this bit is corresponding
HARQ process is not scheduled, such as indicating that the bitmap of the configured information of process 5 and process 6 is 000011000000.
In sum, there is presently no the method indicating multiple HARQ processes, according to existing LTE system downlink transfer institute
Using indicating mode indicate multiple HARQ processes, substantial amounts of signaling consumption will be led to.

HARQ process.
Two specific embodiments are set forth below the division rule of the embodiment of the present invention is illustrated.
Embodiment 1, hypothesis system have K HARQ process, and when this divides to this K HARQ, each process group
Inside there is the HARQ process of repetition, then pth（P is positive integer）Individual process group is by { process p, process p+1 ..., process p+N-1 } group
Become, wherein, N is to enter number of passes in a process group, and N is positive integer, the compound mode according to mode A1 and mode B1 is entered
Row divides, then 1≤p≤K-N+1；Compound mode according to mode A1 and mode B2 is divided, then 1≤p≤K.
For example, in the TDD system of subframe scheduling more than, descending HARQ number of processes is in 12 and the set of many subframe schedulings
Number of subframes be 4, according to the compound mode of mode A1, mode B11 and mode C2, this 12 descending HARQ processes are carried out
Divide, then can get 9 process groups, respectively：1st process group includes { process 1, process 2, process 3, process 4 }, the 2nd
Process group includes { process 2, process 3, process 4, process 5 }, and by that analogy, the 9th process group includes that { process 9, process 10 are entered
Journey 11, process 12 }；
According to the compound mode of mode A1, mode B12 and mode C2, this 12 descending HARQ processes are divided,
Then can get 12 process groups, respectively：1st process group includes { process 1, process 2, process 3, process 4 }, the 2nd process
Group includes { process 2, process 3, process 4, process 5 }, by that analogy, the 9th process group include process 9, process 10, process 11,
Process 12 }, the 10th process group includes { process 10, process 11, process 12, process 1 }, the 11st process group include process 11,
Process 12, process 1, process 2 }, the 12nd process group includes { process 12, process 1, process 2, process 3 }.
Embodiment 2, hypothesis system have K HARQ process, and when this K HARQ process is divided, each process
There is no the HARQ process repeating, then p-th process group is by { process in group（p-1）* N+1, process（p-1）* N+2 ..., process（p-
1）* N+N } composition, wherein, N is to enter number of passes in a process group, and N is positive integer, according to the combination of mode A and mode B
Mode is divided, thenWherein,For the computing that rounds up.
For example, in the TDD system of subframe scheduling more than, descending total number of processes be 12 and the set of many subframe schedulings in
Number of subframes is 4, according to the compound mode of mode A1, mode B1 and mode C1, this 12 descending HARQ processes is carried out draw
Point, then can get 3 process groups, respectively：1st process group includes { process 1, process 2, process 3, process 4 }, and the 2nd is entered
Journey group includes { process 5, process 6, process 7, process 8 }, and the 3rd process group includes { process 9, process 10, process 11, process
12}.
Certainly, the division rule of the embodiment of the present invention can also adopt other modes, such as all HARQ processes is being carried out
It is also possible to different number of HARQ process is divided into one group during division；Or the HARQ randomly selecting in each process group enters
Journey etc..
It should be noted that the division rule of the embodiment of the present invention can be specified by agreement it is also possible to by sending side with connect
Receive side both sides agreement, can also be notified to receiving side by high-level signaling by sending side.
Preferably, if the division rule of the embodiment of the present invention notifies to receiving side by sending side by high-level signaling, this
The method that bright embodiment sends configured information also includes：
Sending side is notified division rule to receiving side by high-level signaling.
Specifically, high-level signaling can be wireless heterogeneous networks（Radio Resource Control, RRC）Or media
Access Control（Media Access Control, MAC）Signaling etc..
Further, the first configured information in the configured information of the embodiment of the present invention can represent have using bit information
Beneficial to the expense reducing signaling.
For example, in the TDD system of subframe scheduling more than, the number of descending HARQ process is 12 and the set of many subframe schedulings
In number of subframes be 4, if this 12 descending HARQ processes are divided according to the dividing mode of embodiment 1,9 can be divided into
Process group or 12 process groups, then can identify this 9 process groups or 12 process groups using 4bits, wherein, bit data with enter
The corresponding relation of journey group can be set as needed, such as represent the 1st process group with " 0000 ", represent the 2nd with " 0001 "
Process group, the like；The 1st process group can also be represented with " 0001 ", represent the 2nd process group, class successively with " 0010 "
Push away；The corresponding relation of bit data and process group can also be set at random, such as represent the 1st process group with " 0101 ", use
" 0011 " represents the 2nd process group, etc., will not enumerate herein；
If this 12 descending HARQ processes are divided according to the dividing mode of embodiment 2,3 process groups can be divided into,
Then this 3 process groups can be identified using 2bits, wherein, bit data can be set as needed with the corresponding relation of process group
Fixed, here is omitted.
Further, the second configured information in the configured information of the embodiment of the present invention can adopt bitmap（Bitmap）Mode
Represent, so can support the flexible dispatching in process group and coupling business demand, it is to avoid the unnecessary wasting of resources；
Specifically, in this bitmap, if bit is " 1 " then it represents that the corresponding HARQ in this bit position enters
Journey is instructed to；If bit is " 0 " then it represents that this bit position corresponding HARQ process is not instructed to.Certainly, also may be used
To represent that this bit position corresponding HARQ process is instructed to " 0 ", represent that this bit position corresponds to " 1 "
HARQ process be not instructed to.
For example, in the TDD system of subframe scheduling more than, the number of descending HARQ process is 12 and the set of many subframe schedulings
The number of middle subframe is 4, according to mode A, this 12 descending HARQ processes is divided, then divides each process obtaining
4 HARQ processes are comprised in group.When only needing to dispatch the 3rd HARQ process in certain process group, then the second configured information pair
The bitmap answering is designated as 0010；When needing the 2nd, 3 HARQ processes in scheduling group, then the second configured information is corresponding
Bitmap is designated as 0110, by that analogy.
Preferably, the first configured information of the configured information of the embodiment of the present invention is represented using bit data, and the second finger
Show that information adopts bitmap mode to represent.
In embodiment TDD system of subframe scheduling more than 3, the number of descending HARQ process is 12 and many subframe schedulings
Number of subframes in set is 4, according to the compound mode of mode A1, mode B11 and mode C2, this 12 descending HARQ is entered
Journey is divided into 9 process groups, then the first configured information needs 4 bits to identify the numbering of this 9 process groups, the second configured information
4 bits are needed to identify the position of the HARQ process comprising in each process group.If desired { n, n+1, the n+ in instruction system
2, n+3 } individual HARQ process, then this corresponding configured information of 4 HARQ processes is as shown in table 1：
| First configured information | Second configured information |
| n2(4bits) | 1111 |
Table 1
Wherein, n2(4bits)Refer to n（Or n-1）Binary representation, and bit be 4.
For example, the if desired process 6 ~ process 9 in instruction system, because the process group that process 6 ~ process 9 is located is the 6th
Process group, then be used for indicating that the configured information of process 6 ~ process 9 is 01101111, wherein, front 4 bits（0110）For first
Configured information, it adopts binary mode, and the numbering for identification process group is 6（I.e. the 6th process group）；4 bits afterwards
（1111）For the second configured information, it adopts bitmap mode, because each bit in this bitmap is " 1 ", then identifies
The 1st ~ 4 process in this process group is all instructed to；
And for example, the if desired process 6 in instruction system and process 7, comprises process 6 and process 7 due in this 9 process groups
Process group be respectively the 4th, 5,6 process groups, corresponding configured information be respectively 01000011,01010110 and
01101100, it is therefore possible to use any of the above-described configured information comes the process 6 in instruction system and process 7.
In embodiment TDD system of subframe scheduling more than 4, descending total number of processes is 12 and the set of many subframe schedulings
In number of subframes be 4, according to the compound mode of mode A1, mode B1 and mode C1, this 12 descending HARQ processes are drawn
It is divided into 3 process groups, then the first configured information needs 2 bits to identify the numbering of this 3 process groups, the second configured information needs
4 bits are identifying the position of the HARQ process comprising in each process group.If desired { m, m+1, m+2, the m+ in instruction system
3 } individual HARQ process, then this corresponding configured information of 4 HARQ processes is as shown in table 2：
Table 2
Wherein,(or）Refer to（Or）Binary representation, and
Bit is 2,For downward rounding operation.
For example, the if desired process 5 ~ process 8 in instruction system, because the process group that process 5 ~ process 8 is located is the 2nd
Process group, then be used for indicating that the configured information of process 5 ~ process 8 is 101111, wherein, front 2 bits（10）For the first instruction
Information, it adopts binary mode, and the numbering for identification process group is 2（I.e. the 2nd process group）；4 bits afterwards
（1111）For the second configured information, it adopts bitmap mode, because each bit in this bitmap is " 1 ", then identifies
The 1st ~ 4 process in this process group is all instructed to；
And for example, the if desired process 6 in instruction system and process 7, because the process group that process 6 and process 7 are located is the 2nd
Individual process group, then the configured information for indicating process 6 and process 7 is 010011.
