Fig. 1 is that the present invention is based on the flow charts of the group service transmission method embodiment one of PUCCH, as shown in Figure 1, this reality
The method for applying example may include:
S100, base station preset the first PUCCH resource and the second PUCCH resource, and the first PUCCH resource includes: N group
The PUCCH and interior each PUCCH of every PUCCH group and channel quality instruction (Channel Quality Indicator, below letter
Claim: CQI) corresponding relationship of grade, the second PUCCH resource include: one group of PUCCH, in group each PUCCH and CQI grade pair
Radio network temporary identifier (the Radio Network Temporary of each PUCCH resource subscript and group in should being related to, organizing
Control channel unit (the Control Channel that Identifier, hereinafter referred to as: RNTI) scrambled PDCCH is occupied
Target one-to-one relationship under Element, hereinafter referred to as: CCE), CQI grade are the range or a CQI difference of a CQI value
Range, N is integer more than or equal to 1.
Wherein, when the RNTI of group is that core net indicates that base station is that group establishes carrying, base station is group allocation, specifically
For, when core net instruction base station is that a group establishes carrying, base station is one RNTI of the group allocation, and is established corresponding
Carrying.
Wherein, if with spectrum efficiency/Signal to Interference plus Noise Ratio (Signal to Interference plus
Noise Ratio, hereinafter referred to as: SINR) quality of wireless channel of/CQI value characterization UE when, CQI grade is a spectrum efficiency
Range/SINR range/CQI value range, alternatively, CQI grade be a spectrum efficiency difference range/SINR difference
Range/CQI difference range.
When CQI grade is the range of a CQI value, UE, which is first measured, obtains the spectral efficiency values/SINR value/CQI of itself
Value, then according to range/SINR range/CQI value range of each PUCCH in preset PUCCH group and spectrum efficiency
Corresponding relationship selects a PUCCH feedback nack message corresponding to the SINR value/spectral efficiency values/CQI value of itself.Specifically
Are as follows: when itself SINR value/spectral efficiency values/CQI value a certain spectrum efficiency range/SINR range/CQI value range
Within when, UE select PUCCH feedback NACK corresponding to range/SINR range/CQI value range of the spectrum efficiency believe
Breath.
When CQI grade is the range of a CQI difference, the difference for the CQI that UE asks the CQI of itself and transmission block to use.
Specifically, UE asks modulation coding scheme (Modulation and Coding Scheme, hereinafter referred to as: MCS) institute of transmission block
Corresponding spectral efficiency values/SINR value/CQI value and own spectrum efficiency value/SINR value/CQI value difference, obtain the first difference.
Then, according to range/SINR difference range/CQI difference of each PUCCH and spectrum efficiency difference in preset PUCCH group

The corresponding relationship of interior PUCCH and CQI grade is exemplified below:
The PUCCH representative value that every group of PUCCH includes is 1,2 or 4.When one group of PUCCH includes 4 PUCCH, each
PUCCH corresponds to a CQI grade, and 4 CQI grades respectively correspond the range an of CQI value or the range of a CQI difference.When
When the quality of wireless channel and CQI grade for using CQI value to characterize UE is the ranges of CQI value, this four CQI grades are as follows: [1,2],
[3,4], [5], [6,7].
The group UE of S101, base station into group sends a notification message.
Scheduling information is sent to group UE by the scrambled PDCCH of RNTI of group by S102, base station, and base station passes through
Transmission block is sent to group UE by PDSCH, is received for the group UE in RRC connected state according to the scheduling information on PDCCH
Transmission block on PDSCH, and when to transmission block decoding error, the UE according to itself CQI and with the first PUCCH resource or
Nack message is fed back to base station by two PUCCH resources.
There are two kinds of situations of dynamic dispatching and semi-persistent scheduling in the present invention, described further below:
One, when using the downlink data of dynamic dispatching transmission group, notification message includes: RNTI and the carrying of group
Configuration information.
For the group of dynamic dispatching, base station will dynamically give one group of the group allocation when dispatching the group every time
PUCCH.The resource subscript of the PUCCH number and each PUCCH that include in the PUCCH group with when each scheduling with the group
The number for the CCE that the scrambled PDCCH of RNTI is occupied and the lower target of the CCE of occupancy are different and different, are dynamic changes.
For dynamic dispatching, the group UE in RRC connected state in the scrambled PDCCH of RNTI for detecting group,
By the number of the PDCCH CCE occupied and the subscript of each CCE, according to the resource subscript and PDCCH of pre-set PUCCH
One-to-one relationship between the CCE subscript of occupancy is dynamically determined and distributes the PUCCH group of the group in this scheduling and include
The resource subscript of PUCCH number and each PUCCH.Group UE in RRC connected state is received according to the scheduling information on PDCCH
Transmission block on PDSCH, when to transmission block decoding error, according to the CQI of itself and pre-set each PUCCH and CQI
Corresponding relationship between grade selects a PUCCH feedback NACK to base station.
Two, when using the downlink data of semi-persistent scheduling transmission group, notification message includes: the RNTI of group, carrying
Configuration information and the first PUCCH resource, the resource of every group of PUCCH includes in N group PUCCH PUCCH number and each PUCCH
Subscript is preset in base station.
To the group of semi-persistent scheduling, these groups are shared as the N group PUCCH of semi-persistent scheduling setting.It is established in group
When, base station notifies N group PUCCH to group.When sending scheduling information to group UE by PDCCH every time, in scheduling information
Include: the group subscript for distributing to the PUCCH of group UE, passes through this group of PUCCH feedback for the group UE in RRC connected state
Nack message.To the group of semi-persistent scheduling, in existing method, group allocation semi-persistent resource is first given in base station, be allocated successfully with
Afterwards, it is sent to using the configuration information of the resource as the scheduling information of semi-persistent scheduling by the scrambled PDCCH of RNTI of group
Group UE.Later group UE can be given by the scheduling information of the scrambled PDCCH periodicity sending semi-persistent scheduling of RNTI of group.
At the interval that PDCCH twice is sent, group UE receives interim base station according to the scheduling information on the PDCCH being most recently received
The transmission block of transmission.
In the present invention, to the group of semi-persistent scheduling, the scheduling information of semi-persistent scheduling is being passed through group by base station
It include under the PUCCH group for distributing to group UE in N group PUCCH when the scrambled PDCCH of RNTI is sent to group UE, in scheduling information
Mark.Group UE receives the scrambled PDCCH of RNTI of group, obtains under the PUCCH group that group UE is distributed in base station in scheduling information
Mark.Group UE in RRC connected state obtains the PUCCH group of distribution according to PUCCH group subscript.Group in RRC connected state
UE receives the transmission block on PDSCH according to the scheduling information on PDCCH, when to transmission block decoding error, according to the CQI of itself
With the corresponding relationship of each PUCCH and CQI grade in PUCCH group, select a PUCCH feedback NACK to base station.
When the group UE in RRC connected state passes through the dedicated PUCCH feedback nack message configured in the prior art,
Multiple UE will cause the superposition of multiple UE power on the code channel by same code channel feedback, cause to this cell and adjacent cell
No matter bursty interference, above-mentioned setting according to the present invention use dynamic dispatching or semi-persistent scheduling, in RRC connected state
Group UE can pass through one group of PUCCH feedback nack message of setting, when the PUCCH for including in this group of PUCCH is greater than 1, UE
A PUCCH feedback nack message is selected according to default rule, therefore can be dispersed and interfered caused by this cell and adjacent cell.
One group of PUCCH is dynamically distributed to the group of dynamic dispatching in the present invention, uses group when this group of PUCCH by dispatching every time
The CCE resource subscript that occupies of the scrambled PDCCH of RNTI determine.Under the CCE resource occupied according to existing 3GPP agreement, PDCCH
Even if marking corresponding PUCCH is not assigned to the group, and idle.Therefore, this group of PUCCH is distributed into the group, it is only sharp
With idle PUCCH, PUCCH resource is not occupied additionally.
To semi-persistent scheduling, by PDCCH assignment of allocation to the PUCCH group subscript of group, all semi-static tune can be allowed
N group PUCCH resource is shared by the group of degree.Resource is saved compared to one group of dedicated PUCCH of group allocation.
Wherein, PUCCH group subscript can be indicated by domain specific on PDCCH or by PDCCH first CCE's used
Subscript indicates PUCCH group subscript.CCE subscript can be arranged by base station in advance with the lower target mapping relations of PUCCH group.
Specifically, when being in group's UE decoding error of RRC connected state, these groups UE according to itself CQI and
Each PUCCH and the corresponding relationship of CQI grade select a PUCCH feedback nack message in PUCCH group specifically:
It is, for example, CQI1 that group UE, which obtains the CQI value that current transmission block uses according to scheduling information first, then according to certainly
It is, for example, CQI2 that body measurement, which obtains itself desired CQI value,.Seek difference CQI1-CQI2=DELTA_CQI.When CQI grade is one
When the range of a CQI difference, UE selects CQI difference range belonging to DELTA_CQI from the PUCCH group of distribution, passes through the difference
Nack message is fed back to base station by the corresponding PUCCH of value range.When CQI grade is the range of a CQI value, UE is from distribution
The range that CQI value belonging to CQI2 is selected in PUCCH group, feeds back to base station for nack message by the corresponding PUCCH of the range.
S103, base station pass through PUCCH pairs of the feedback nack message detected when having detected that UE feeds back nack message
The CQI grade answered obtains the desired CQI of UE of feedback nack message.
Specifically, the channel quality of UE is time-varying and different in group.RRC connection is in decoding error
In the group UE of state, UE selects PUCCH according to the channel quality of itself, it may appear that: different UE is due to respective channel quality
Belong to different CQI grade (that is: belonging to different CQI value range or CQI difference range) and selects different PUCCH feedbacks
Nack message.But also will appear: the channel quality of some UE belongs to same CQI grade by chance, and the PUCCH of selection is identical.
Each PUCCH in the PUCCH group of group UE is distributed in base station detection.When detecting: passing through in group without any UE
When PUCCH feedback nack message, it is believed that current transmission block is properly received by each group UE in RRC connected state.Work as detection
To have UE by group in some PUCCH feedback nack message when, corresponding CQI of PUCCH by detecting nack message etc.
Grade obtains the desired CQI of UE that RRC connected state is in by those of the PUCCH feedback nack message.When base station detect it is more
When the nack message of a PUCCH Shang You group UE feedback, group UE institute's phase that nack message is fed back on each PUCCH can be obtained
The CQI of prestige.Base station can carry out retransfer scheduling and adjustment by multiple desired CQI and just pass.
In order to better disperse the interference caused by this cell and adjacent cell, base station preset the first PUCCH resource and
When the second PUCCH resource, further includes:
It presets: when group's UE decoding error in RRC connected state, the Block Error Rate (Block that is only obtained in measurement
Error Rate, hereinafter referred to as: BLER) it is greater than or equal to the first BLER threshold value Shi Zaixiang base station feedback nack message.First
BLER threshold value is the BLER target value less than or equal to group service.
S104, base station just pass next time according to the desired CQI progress retransfer scheduling of at least one UE of acquisition and adjustment
MCS。
Specifically, when the group's UE decoding error for having more than one to be in RRC connected state, base station passes through detection
Each PUCCH in PUCCH group knows the distribution situation of the desired CQI of group UE of feedback nack message.
Base station can select a minimum value in the desired CQI of multiple UE, carry out retransfer scheduling according to the minimum value.This
Sample can guarantee: the group UE in RRC connection state of all feedback nack messages can be passed by receiving to retransmit in group
Defeated piece of progress correct decoding.
Base station can also adjust the MCS just passed according to the minimum value, guarantee that the transmission just passed can be owned in group fastly
UE correct decoding in RRC connected state.
Specifically, according to the desired CQI progress retransfer scheduling of at least one UE of acquisition, there are two types of can be real for base station in S104
The mode applied is as follows:
One, base station sends the scheduling information retransmitted by PDCCH and gives group UE, and is sent to transmission block by PDSCH
Group UE.Using adaptive retransmission, group UE monitors the PDCCH that base station is sent for base station at this time, when receiving group
When the scrambled PDCCH of RNTI, indicate to receive the transmission block sent on PDSCH according to PDCCH.
Two, non-adaptive re-transmission is supported in base station.Specifically, base station presets the first PUCCH resource and the 2nd PUCCH money
When source, further includes:
The timing relationship between subframe that the PUCCH subframe and PDSCH for presetting feedback nack message retransmit；
Base station carries out retransfer scheduling according to the desired CQI of at least one UE of acquisition, comprising:
Base station does not send PDCCH in the subframe that PDSCH is retransmitted, according to just pass identical scheduling information pass through PDSCH send out
Transmission block is sent, the group UE for feeding back nack message is received on PDSCH in the subframe that PDSCH is retransmitted according to the scheduling information just passed
Transmission block.
Further, when defined re-transmission subframe downlink resource is inadequate, base station presets the first PUCCH resource for base station
When with the second PUCCH resource, further includes:
Preset the PUCCH subframe of group UE feedback nack message and by Physical HARQ Indicator Channel (Physical
The timing relationship between the PHICH subframe of ACK information HARQ Indicator Channel, hereinafter referred to as: PHICH) is sent, in advance
The first mapping relations of the PUCCH group subscript of setting feedback nack message and PHICH code channel.Group UE is after feeding back nack message
PHICH is received in pre-set PHICH subframe.By on PHICH whether loading ACK information determine whether to carry out it is non-adaptive
It retransmits.
Base station carries out retransfer scheduling according to the desired CQI of at least one UE of acquisition at this time, comprising:
Base station sends ACK information by PHICH to notify the group UE of feedback nack message without non-adaptive re-transmission.
The group UE for feeding back nack message receives PHICH according to timing relationship, when PHICH instruction is without retransmitting, no
It receives and retransmits in regulation subframe, do not feed back nack message, otherwise receive and retransmit in regulation subframe.
Preferably, pre-set send is determined between PDCCH subframe and the PUCCH subframe of group UE feedback nack message
When relationship can according in 3GPP agreement send scheduling information PDCCH subframe and feeding back ACK/nack message PUCCH subframe
Between timing relationship be defined.
Preferably, when supporting non-adaptive re-transmission, the PUCCH subframe of pre-set group UE feedback nack message with
The timing relationship that PDSCH retransmits subframe can retransmit subframe according to 3GPP feeding back ACK/nack message PUCCH subframe and PDSCH
