Description
Technical field
The present invention relates to wireless communication techniques more particularly to a kind of method, apparatus, base station and user for merging feedback to set
It is standby.
Background technique
Long term evolution (Long Term Evolution, LTE) is by third generation partner program (The 3rd
Generation Partnership Project, 3GPP) Universal Mobile Communication System (Universal that organizes to set up
Mobile Telecommunications System, UMTS) technical standard long term evolution, it is more in 3GPP in December, 2004
It formally sets up the project and starts in the more meetings of human relations.LTE system introduces orthogonal frequency division multiplexing (Orthogonal Frequency
Division Multiplexing, OFDM) and multiple-input and multiple-output (Multi-Input&Multi-Output, MIMO) etc. close
Key technology significantly increases spectrum efficiency and message transmission rate, and various bandwidth is supported to distribute: 1.4MHz, 3MHz, 5MHz,
10MHz, 15MHz and 20MHz etc., and support global mainstream 2G/3G frequency range and some newly-increased frequency ranges, thus frequency spectrum distribution is cleverer
Living, power system capacity and covering are also obviously improved.The LTE system network architecture more flattening, simplify, reduce network node and
System complexity also reduces network deployment and maintenance cost to reduce Time Delay of Systems.LTE system is supported and other
3GPP system interoperability.According to duplex mode difference, LTE system is divided into frequency division duplex (Frequency Division
Duplex, FDD) LTE and time division duplex (Time Division Duplex, TDD) LTE.FDD LTE uplink and downlink uses pairs of
UHF band reception and transmission data, and TDD LTE uplink and downlink is then transmitted on different time slots using identical frequency range.In FDD
In LTE, user equipment (User Equipment, UE) uses the Physical Uplink Shared Channel of designated spectrum resource in subframe n
(Physical Uplink Shared Channel, PUSCH) carries out transmitting uplink data, and base station parses what user equipment was sent
Upstream data, and physical mixed automatic re-transmission indicating channel (Physical Hybrid ARQ is sent on subframe n+4
Indicator Channel, PHICH), indicate hybrid automatic repeat-request (Hybrid Automatic Repeat
Request, HARQ) feedback information, i.e. confirmation (Acknowledgement, ACK) or negative acknowledge (Negative
Acknowledgment, NACK).Specifically, if it is possible to accurately receive upstream data, then base station is on the PHICH of subframe n+4
Instruction confirmation；If cannot accurately receive upstream data or be not received by upstream data, PHICH of the base station in subframe n+4
Upper instruction negative acknowledge.
In TDD LTE, user equipment carries out transmitting uplink data in subframe n, and base station is needed at subframe n+k (k >=4)
PHICH on indicate ACK or NACK, it should be pointed out that there is unique k value to be corresponding to it specified n value.
The transmission of PHICH can carry out tissue in the form of PHICH group, and multiple PHICH channels in 1 PHICH group use
The multiplex mode of orthogonal spreading sequence occupies identical time-frequency domain physical resource.For example, in normal cyclic prefix (Cyclic
Prefix, CP) when, a PHICH group is multiplexed 8 PHICH channels, provides 8 PHICH resources, i.e. base station can be to 8 users
Equipment indicates the ACK or NACK (it is assumed that a user equipment only transmits a transmission block) of its uplink.PHICH resource by
Mark codetermines in PHICH group mark and group.User equipment passes through the transmission occupied Physical Resource Block of upstream data
Position (the minimum object of the user equipment in first slot transmission upstream data of (Physical Resource Block, PRB)
Manage resource block index) and demodulation reference signal (De-Modulation Reference Signal, DMRS) circulation
Displacement (Cyclic Shift, CS) determines mark in the PHICH group mark and group of a PHICH resource.
Usual LTE is always deployed in authorization (licensed) frequency spectrum resource that operator possesses, but authorizes frequency spectrum resource non-
It is often rare, therefore operator starts to consider to make full use of unauthorized (unlicensed) frequency spectrum resource, such as the frequency spectrum resource of 5GHz
Carry out data transmission.Before base station is using unlicensed spectrum resource, need to use first to listen to say (Listen Before afterwards
Talk, LBT) mechanism, monitor whether have other users such as Wireless LAN (Wireless Local Area Networks,
WLAN the unlicensed spectrum resource) is used, if it is determined that the channel of unlicensed spectrum is in busy condition, then needs
To；When the channel for determining unlicensed spectrum is in idle condition, then the unlicensed spectrum resource of a period of time can be used.Example
Such as, when Japan can at most be used continuously up to the unlicensed spectrum resource of 4ms, when other countries allow to be used continuously
Between can be longer.When this unlicensed spectrum resource is using completing, base station needs to discharge the unlicensed spectrum resource, so
Monitor the right to use for obtaining unlicensed frequencies resource next time again afterwards.
When base station is when the channel of unlicensed spectrum sends PHICH, if the channel of unlicensed spectrum is in busy condition,
Then base station needs to wait and sends PHICH after postponing several subframes, it is possible to it is anti-the corresponding HARQ of multiple PUSCH subframes occur
The situation to be transmitted such as feedforward information.The base station sends the corresponding HARQ feedback of multiple PUSCH subframes in same PHICH subframe
Situation, which is referred to as, merges feedback.
In the prior art, when the corresponding HARQ feedback of multiple PUSCH subframes is closed in same PHICH subframe in base station
And when feeding back, the HARQ feedback of different PUSCH subframes is possible to correspond to the same PHICH resource simultaneously, leads to user equipment
As soon as every PUSCH subframe corresponding PHICH resource in the PHICH subframe can not can be determined, can not also be correctly received anti-
Feedforward information.

Specifically, the PHICH resource block message can pass through wireless heterogeneous networks (Radio Resource
Control, RRC) user equipmenies of all feedbacks to be received of signaled saves wireless to effectively reduce signaling overheads
Resource.
It is the method for salary distribution of the PHICH subframe for the method that one of embodiment of the present invention merges feedback referring to Fig. 2, Fig. 2
Schematic diagram.As a unrestricted example, sets the PHICH resource in PHICH subframe 201 and be divided into 3 PHICH moneys
Source block, PHICH subframe 201 include 6 PHICH groups altogether, and the HARQ that the PHICH subframe 201 corresponds to 3 PUSCH subframes is anti-
Feedback namely the corresponding PUSCH subframe of each PHICH resource block.It is understood that PHICH resource in the embodiment of the present invention
Division mode be not limited to this.
More specifically, the PHICH resource in PHICH subframe 201 is divided into multiple PHICH moneys using PHICH group as granularity
Source block (such as may include 3 PHICH resource blocks 202~204), each PHICH resource block include at least one PHICH group.
As a non-limitative example, PHICH resource block 202 may include 2 PHICH groups 205~206, PHICH resource block 203
It may include 1 PHICH group 207, PHICH resource block 203 may include 3 PHICH groups 208~210.
Each PHICH resource block and PUSCH subframe have specific corresponding relationship can as a non-limitative example
To set the HARQ feedback that a PHICH resource block only corresponds to a PUSCH subframe.Such as PHICH resource block 202 is served only for holding
The HARQ feedback of PUSCH subframe 211 is carried, PHICH resource block 203 is served only for the HARQ feedback of carrying PUSCH subframe 212, PHICH
Resource block 204 is served only for the HARQ feedback of carrying PUSCH subframe 213.
In specific implementation, it includes: each PHICH that each PHICH resource block and PUSCH subframe, which have corresponding relationship,
Resource block and first time difference have corresponding relationship, and the first time difference is the PUSCH subframe and PHICH
The time difference of frame.
For example, user equipment carries out transmitting uplink data in subframe n (namely PUSCH subframe), normal in FDD LTE
In the case of rule, base station sends PHICH in subframe n+4 (namely PHICH subframe), and the first time difference is 4 subframes.And
It, must not when base station can not obtain the right to use of unlicensed spectrum resource on subframe n+4 in the case where being related to first listening and saying mechanism afterwards
Do not postpone m subframe (m >=1) when subframe n+4+m (namely PHICH subframe) sends PHICH, in this case, described first
Time difference is 4+m subframe.
It is understood that user equipment carries out upstream data biography in subframe n (namely PUSCH subframe) in TDD LTE
Defeated, in normal conditions, base station sends PHICH, the first time difference in subframe n+k (k >=4) (namely PHICH subframe)
It is k subframe.And be related to first listening say mechanism afterwards in the case where, when base station can not be obtained on subframe n+k unlicensed spectrum money
The right to use in source, it has to postpone m subframe (m >=1) when subframe n+k+m (namely PHICH subframe) sends PHICH, this
In the case of, the first time difference is k+m subframe.
Preferably, the embodiment of the present invention can set regular time difference for each PHICH resource block, such as set
The corresponding time difference of PHICH resource block 202 is 4, and the corresponding time difference of resource block 203 is 5, resource block 204
The corresponding time difference is 6.It is assumed that the PHICH subframe numbers of PHICH to be sent are 8, base station needs to be 2,3,4 to subframe numbers
PUSCH subframe carry out HARQ feedback.According to time difference calculated result, PUSCH subframe that base station is 4 for subframe numbers
HARQ feedback will be sent in PHICH resource block 202, that is to say, that resource block 202 corresponds to the PUSCH's that subframe numbers are 4
HARQ feedback；Similar, resource block 203 corresponds to the HARQ feedback for the PUSCH subframe that subframe numbers are 3, and resource block 204 corresponds to
The HARQ feedback for the PUSCH subframe that subframe numbers are 2.
In another specific example, it includes: each that each PHICH resource block, which has corresponding relationship with PUSCH subframe,
PHICH resource block and the second time difference have corresponding relationship, and second time difference is that the PUSCH subframe is corresponding pre-
If the time difference of PHICH subframe and the PHICH subframe, wherein the default PHICH subframe and the PUSCH subframe have
There is preset timing corresponding relationship.
For example, user equipment carries out transmitting uplink data, base station in subframe n (namely PUSCH subframe) in FDD LTE
PHICH is sent in subframe n+4 (namely default PHICH subframe), that is to say, that default PHICH subframe and the PUSCH subframe
Send 4 subframes in interval.
But due to first listening the mechanism said afterwards, when base station can not obtain the use of unlicensed spectrum resource on subframe n+4
Power, it has to postpone m subframe (m >=1) when subframe n+4+m (namely PHICH subframe of actual use) sends PHICH, it is described
Second time difference is m, the transmission interval subframe of the PHICH subframe of the default PHICH subframe and the actual use.
It is understood that user equipment carries out upstream data biography in subframe n (namely PUSCH subframe) in TDD LTE
Defeated, base station sends PHICH in subframe n+k (k >=4) (namely default PHICH subframe), that is to say, that default PHICH subframe with
K, the transmission interval subframe of the PUSCH subframe.
Due to first listening the mechanism said afterwards, when base station can not obtain the right to use of unlicensed spectrum resource on subframe n+k, no
Not postpone m subframe (m >=1) when subframe n+k+m (namely PHICH subframe of actual use) sends PHICH, described second
Time difference is m, the transmission interval subframe of the PHICH subframe of the default PHICH subframe and the actual use.
Furthermore, the embodiment of the invention provides two kinds of alternative methods for calculating time difference, in reality
In, calculation method can be selected according to the actual situation, help to improve the accuracy of information.In addition, above two calculating
Method is only example, and unrestricted.
With continued reference to Fig. 1, in the specific implementation of step S102, calculated according to the PHICH resource block message for more
The PHICH resource that the HARQ feedback of a PUSCH subframe uses in the PHICH subframe includes: to be existed according to the user equipment
The cyclic shift of minimum PRB index and DMRS used in the first time slot uplink of PUSCH subframe, it is anti-to calculate the HARQ
The PHICH resource of feedback mark in the group mark and group in corresponding PHICH resource block.
Wherein it is determined that the formula identified in group mark and group in PHICH resource block can be with are as follows:
Wherein,Indicate the group mark in PHICH resource block；Mark in expression group；It indicates
The number of PHICH group in PHICH resource block；Indicate user equipment on first time slot of PUSCH subframe
Row transmits used minimal physical resource block index；nDMRSIndicate the cyclic shift of DMRS used in user equipment；Indicate spreading factor (Spreading Factor Size Used For PHICH when PHICH modulation
Modulation size).
It will be appreciated by those skilled in the art that the group mark that above-mentioned formula is calculated is the group mark in PHICH resource block
The information such as the PHICH group that knowledge, base station and user equipment can include according to each PHICH resource block will be in PHICH resource block
Group mark is converted to the mark of the group in PHICH subframe 201.
Specifically, since each PHICH resource block and PUSCH subframe have specific corresponding relationship, according to different
PUSCH subframe can also be located in different PHICH resource blocks even if calculating mark in identical PHICH group mark and group.
That is, having mark in group mark and the group in the PHICH resource block not conflicted right therewith different PUSCH subframes
It answers, the embodiment of the present invention solves the HARQ feedback for merging the different PUSCH subframes in feedback while corresponding to the same PHICH
The collision problem of resource.
Further, according to background technique it is found that the input parameter and the prior art of the used formula of the embodiment of the present invention
In input parameter it is almost the same, increase only parameter known to numerical value, that is to say, that input parameter without additional acquisition, i.e.,
Mark in group mark and the group in PHICH resource block can be calculated, the influence to system complexity is simultaneously little.
It will be appreciated by those skilled in the art that the HARQ feedback for multiple PUSCH subframes is calculated described
After the PHICH resource used in PHICH subframe, it is anti-to carry corresponding HARQ that the PHICH resource being calculated can be used
