Fig. 1 is the flow chart of present invention group service based on PUCCH transmission method embodiment one, as
Shown in Fig. 1, the method for the present embodiment may include that
S100, base station pre-set the first PUCCH resource and the second PUCCH resource, a PUCCH
Resource includes: in N group PUCCH and each PUCCH group, each PUCCH indicates with channel quality
The corresponding relation of (Channel Quality Indicator, hereinafter referred to as: CQI) grade, the 2nd PUCCH
Resource includes: every in the corresponding relation of each PUCCH Yu CQI grade, group in one group of PUCCH, group
Individual PUCCH resource subscript and Radio Network Temporary Identifier (the Radio Network Temporary of group
Identifier, hereinafter referred to as: the RNTI) control Channel Elements (Control that the PDCCH scrambled takies
Target one-to-one relationship under Channel Element, hereinafter referred to as: CCE), CQI grade is one
The scope of CQI value or the scope of a CQI difference, N is the integer more than or equal to 1.
Wherein, the RNTI of group be core net instruction base station be group set up carrying time, base station is group
Distribution, specifically, when core net instruction base station is group's foundation carrying, base station is this group
Component joins a RNTI, and sets up corresponding carrying.
Wherein, if with spectrum efficiency/Signal to Interference plus Noise Ratio (Signal to Interference plus
When Noise Ratio, hereinafter referred to as: SINR)/CQI value characterizes the quality of wireless channel of UE, CQI etc.
Level is the scope of the scope/CQI value of the scope/SINR of a spectrum efficiency, or, CQI grade is one
The scope of the scope of the scope of individual spectrum efficiency difference/SINR difference/CQI difference.
When the scope that CQI grade is a CQI value, UE first measures the spectral efficiency values obtaining self
/ SINR value //CQI value, then according to each PUCCH and spectrum efficiency in the PUCCH group preset
The corresponding relation of scope of scope/CQI value of scope/SINR, select the SINR value/frequency spectrum of self

The corresponding relation of interior PUCCH with CQI grade is exemplified below:
The PUCCH representative value that often group PUCCH includes is 1,2 or 4.When one group of PUCCH bag
When including 4 PUCCH, the corresponding CQI grade of each PUCCH, 4 CQI grades are respectively
The scope of a corresponding CQI value or the scope of a CQI difference.UE is characterized when using CQI value
Quality of wireless channel and during scope that CQI grade is CQI value, these four CQI grades are: [1,
2], [3,4], [5], [6,7].
S101, the base station group UE in group sends a notification message.
Schedule information is sent to group by the PDCCH that S102, base station are scrambled by the RNTI of group
UE, transmission block is sent to group UE by PDSCH by base station, for being in the group of RRC connected state
Group UE receives the transmission block on PDSCH according to the schedule information on PDCCH, and is translating transmission block
During code mistake, this UE is according to self CQI and and the first PUCCH resource or the 2nd PUCCH money
Nack message is fed back to base station by source.
The present invention has dynamic dispatching and two kinds of situations of semi-persistent scheduling, described further below:
One, when the downlink data using dynamic dispatching to transmit group, notification message includes: the RNTI of group
Configuration information with carrying.
For the group of dynamic dispatching, base station, when dispatching this group every time, will divide dynamically to this group
Join one group of PUCCH.The PUCCH number included in this PUCCH group and the resource of each PUCCH
The number of the CCE that subscript takies with the PDCCH scrambled with the RNTI of this group during every time scheduling and accounting for
The lower target of CCE different and different, be dynamically to change.
For dynamic dispatching, the group UE being in RRC connected state adds at the RNTI of detection group
During the PDCCH disturbed, the number of the CCE taken by PDCCH and the subscript of each CCE, according to
One_to_one corresponding between the CCE subscript that the resource subscript of the PUCCH pre-set and PDCCH take
Relation, is dynamically determined in this scheduling and distributes PUCCH number that the PUCCH group of this group includes and every
The resource subscript of individual PUCCH.It is in the group UE of RRC connected state according to the scheduling on PDCCH
Information receives the transmission block on PDSCH, when to transmission block decoding error, according to self CQI and
Corresponding relation between each PUCCH and the CQI grade pre-set, selects a PUCCH anti-
NACK is to base station in feedback.
Two, when the downlink data using semi-persistent scheduling to transmit group, notification message includes: group
RNTI, the configuration information of carrying and the first PUCCH resource, often organize PUCCH in N group PUCCH
Including PUCCH number and the resource subscript of each PUCCH be to pre-set in base station.
Group to semi-persistent scheduling, these groups are shared as N group PUCCH that semi-persistent scheduling is arranged.
When group sets up, N group PUCCH is notified to group by base station.Pass through PDCCH to group every time
When group UE sends schedule information, schedule information includes: under the group of the PUCCH distributing to group UE
Mark, for being in the group UE of RRC connected state by this group PUCCH feedback nack message.Right
The group of semi-persistent scheduling, in existing method, group allocation semi-persistent resource is first given in base station, is allocated successfully
After, the configuration information of this resource is added as the schedule information of semi-persistent scheduling by the RNTI of group
The PDCCH disturbed is sent to group UE.Later can be by the PDCCH cycle of the RNTI scrambling of group
Property send semi-persistent scheduling schedule information to group UE.In the interval of twice PDCCH transmission, group
UE receives, according to the schedule information on the PDCCH being most recently received, the transmission that interim base station sends
Block.
In the present invention, the group to semi-persistent scheduling, the schedule information of semi-persistent scheduling is being led to by base station
When the PDCCH of the RNTI scrambling crossing group is sent to group UE, schedule information includes N group
PUCCH distributes to the PUCCH group subscript of group UE.Group UE receives the RNTI of group and adds
The PDCCH disturbed, it is thus achieved that in schedule information, the PUCCH group subscript of group UE is distributed in base station.It is in
The group UE of RRC connected state obtains the PUCCH group of distribution according to PUCCH group subscript.It is in RRC
The group UE of connected state receives the transmission block on PDSCH according to the schedule information on PDCCH, when right
During transmission block decoding error, according to each PUCCH Yu CQI in CQI and the PUCCH group of self etc.
The corresponding relation of level, selects PUCCH feedback NACK to base station.
The group UE being in RRC connected state in prior art is anti-by the special PUCCH configured
During feedback nack message, multiple UE can cause multiple UE on this code channel by same code channel feedback
The superposition of power, causes bursty interference to this community and adjacent cell, according to the above-mentioned setting of the present invention, nothing
Opinion uses dynamic dispatching or semi-persistent scheduling, and the group UE being in RRC connected state all can be by arranging
One group of PUCCH feedback nack message, when the PUCCH comprised in this group PUCCH is more than 1
Time, UE selects a PUCCH feedback nack message according to default rule, and it is right therefore to dispersible
The interference that this community and adjacent cell cause.
Dynamically distributing one group of PUCCH in the present invention group of dynamic dispatching, this group PUCCH is by every time
The CCE resource subscript that the PDCCH scrambled with the RNTI of group during scheduling takies determines.According to existing
3GPP agreement, even if PUCCH corresponding to the CCE resource subscript that takies of PDCCH is not assigned to this group
Group, is also idle.Therefore, this group PUCCH is distributed to this group, just with leave unused
PUCCH, the most additionally takies PUCCH resource.
To semi-persistent scheduling, by PDCCH assignment of allocation to the PUCCH group subscript of group, Ke Yirang
N group PUCCH resource is shared by the group of all semi-persistent schedulings.Special compared to group allocation one group
PUCCH resource to be saved.
Wherein, by specific territory instruction PUCCH group subscript on PDCCH or can be adopted by PDCCH
First CCE subscript instruction PUCCH group subscript.CCE subscript and target under PUCCH group
Mapping relations can be arranged by base station in advance.
Specifically, when being in group's UE decoding error of RRC connected state, these groups UE root
One is selected according to the corresponding relation of each PUCCH Yu CQI grade in CQI and the PUCCH group of self
PUCCH feedback nack message particularly as follows:
First group UE obtains, according to schedule information, the CQI value for example, CQI1 that current transmission block uses,
Then measure according to self and obtain self desired CQI value for example, CQI2.Seek difference CQI1-CQI2
=DELTA_CQI.When the scope that CQI grade is a CQI difference, UE is from the PUCCH of distribution
Group selects the CQI difference range belonging to DELTA_CQI, by the PUCCH that this difference range is corresponding
Nack message is fed back to base station.When the scope that CQI grade is a CQI value, UE is from distribution
PUCCH group in select the scope of CQI value belonging to CQI2, by the PUCCH that this scope is corresponding
Nack message is fed back to base station.
S103, base station are when having detected that UE feeds back nack message, by feedback NACK detected
The CQI grade corresponding for PUCCH of information obtains the desired CQI of UE of feedback nack message.
Specifically, in group, the channel quality of UE is time-varying and different.At decoding error
Being in the group UE of RRC connected state, UE selects PUCCH according to the channel quality of self, can go out
Existing: different UE (that is: belongs to different owing to respective channel quality belongs to different CQI grades
CQI value scope or CQI difference range) and select different PUCCH feedback nack messages.But,
Also there will be: the channel quality of some UE belongs to same CQI grade by chance, the PUCCH phase of selection
With.
Each PUCCH in the PUCCH group distributing to group UE is detected in base station.When detecting: do not have
During any UE PUCCH feedback nack message interior by group, it is believed that current transmission block is in by each
The group UE of RRC connected state is properly received.When having detected that UE is by some PUCCH in organizing
During feedback nack message, by CQI grade corresponding for the PUCCH of nack message being detected,
Obtain that to be in the UE of RRC connected state by those of this PUCCH feedback nack message desired
CQI.When base station detects the nack message that multiple PUCCH Shang You group UE feeds back, permissible
Obtain the desired CQI of group UE feeding back nack message on each PUCCH.Base station can lead to
Cross multiple desired CQI carry out retransfer scheduling and adjust just biography.
In order to preferably disperse the interference causing this community and adjacent cell, base station pre-sets first
When PUCCH resource and the second PUCCH resource, also include:
Pre-set: when being in group's UE decoding error of RRC connected state, the mistake only obtained in measurement
Block rate (Block Error Rate, hereinafter referred to as: BLER) more than or equal to a BLER threshold value time again
To base station feedback nack message.Oneth BLER threshold value is the BLER mesh less than or equal to group service
Scale value.
Under S104, base station carry out retransfer scheduling according to the desired CQI of at least one UE obtained and adjust
The MCS once just passed.
Specifically, when the group's UE decoding error having more than one to be in RRC connected state, base station
By each PUCCH in detection PUCCH group, know group UE institute's phase of feedback nack message
The distribution situation of the CQI hoped.
Base station can select a minima in the desired CQI of multiple UE, carries out according to this minima
Retransfer scheduling.So can ensure that: in group, the RRC that is in of all feedback nack messages couples state
Group UE can by receive retransmit transmission block carry out correct decoding.
Base station can also adjust, according to this minima, the MCS just passed, it is ensured that the transmission just passed soon can be by group
All UE correct decodings being in RRC connected state in group.
Specifically, in S104, base station carries out retransfer scheduling according to the desired CQI of at least one UE obtained
There are two kinds of enforceable modes, as follows:
One, base station sends the schedule information retransmitted to group UE by PDCCH, and passes through PDSCH
Transmission block is sent to group UE.Now base station uses adaptive retransmission, and group UE monitors base station
The PDCCH sent, as the PDCCH that the RNTI receiving group scrambles, refers to according to PDCCH
Show and receive the transmission block sent on PDSCH.
Two, base station supports that non-self-adapting retransmits.Specifically, base station pre-sets the first PUCCH resource
During with the second PUCCH resource, also include:
Pre-set between the PUCCH subframe of feedback nack message and the subframe of PDSCH re-transmission
Timing relationship；
Base station carries out retransfer scheduling according to the desired CQI of at least one UE obtained, including:
The subframe that base station retransmits at PDSCH does not send PDCCH, according to the schedule information identical with just biography
Transmission block, the subframe that the group UE of feedback nack message retransmits is sent at PDSCH by PDSCH
The transmission block on PDSCH is received according to the schedule information just passed.
Further, base station is when the re-transmission subframe downlink resource of regulation is inadequate, and base station pre-sets first
When PUCCH resource and the second PUCCH resource, also include:
Pre-set the PUCCH subframe of group UE feedback nack message and referred to by physics HARQ
Show that channel (Physical HARQ Indicator Channel, hereinafter referred to as: PHICH) sends ACK letter
Timing relationship between the PHICH subframe of breath, pre-sets under the PUCCH group of feedback nack message
Mark and the mapping relations of PHICH code channel.Group UE is pre-setting after feedback nack message
PHICH subframe receives PHICH.By on PHICH whether loading ACK information determine whether to carry out non-
Adaptive retransmission.
Now base station carries out retransfer scheduling according to the desired CQI of at least one UE obtained, including:
Base station sends ACK information by PHICH and does not enters with the group UE of notice feedback nack message
Row non-self-adapting retransmits.
The group UE of feedback nack message receives PHICH according to timing relationship, indicates at PHICH
When not retransmitting, do not receive in regulation subframe and retransmit, do not feed back nack message, otherwise at regulation
Frame receives and retransmits.
Preferably, the transmission PDCCH subframe pre-set and group UE feed back nack message
Timing relationship between PUCCH subframe can be according to the PDCCH sending schedule information in 3GPP agreement
