Description
Technical field
The present invention relates to communication technical field, the side that PUCCH resource position is distributed in more particularly to a kind of lte-a system
Method, and, the system that PUCCH resource position is distributed in a kind of lte-a system.
Background technology
In LTE（Long Term Evolution, long evolving system）In system, LTE-A（LTE-Advanced is advanced
Long evolving system）It is LTE evolution version, in order to meet the descending peak speed 1Gbps of LTE-A, up peak speed 500Mbps's will
Ask, it is desirable to provide maximum 100MHz transmission bandwidth, but due to so big bandwidth continuous frequency spectrum it is rare, LTE-A is proposed
Carrier aggregation（Carrier Aggregation, CA）Solution.So-called carrier aggregation, is by the carrier wave list of 2 or more
Member（Component Carrier, CC）Condense together and be 100MHz transmission bandwidth to the maximum with support.
PUCCH（Physical Uplink Control CHannel, physical uplink control channel）Main carrying SR
（Schedule Request, dispatch request）, ACK/NACK（Acknowledgement, positive acknowledgment/Negative
Acknowledgement, NACK）And CQI/PMI（Channel Quality Indicator, down channel quality refers to
Show/Precoding Matrix Indicator, pre-coding matrix instruction）, RI（Rank Indicator, stratum indicates）, it is right
Should be in PUCCH Format1, Format1A/1B and Format2/2A/2B form.
Format1：For UE（User Equipment, user equipment）Up transmission dispatch request, base station side only needs inspection
Survey with the presence or absence of such transmission；
Format1A/1B：For the up transmission ACK/NACK of UE；
Format1 is in system L3（Layer 3）Transmitted over resources of the signal deployment to SR；Format1A/1B with descending PDCCH
（Physical Downlink Control CHannel, physical downlink control channel）CCE（Control Channel
Element, control channel unit）Corresponding PUCCHACK/NACK transmitted over resources；When SR and uplink ACK/NACK need together
When transmitting, in transmitted over resources uplink ACK/NACK of the L3 signal deployments to SR.The money that uplink ACK takes is transmitted on PUCCH
Source is by RB（Resource Block, resource block）ID, frequency domain CDM code（Frequency domain code）And time
domain CDM code（When field code）It is determined that.
Format2：ACK/NACK information for sending 20 bits after up CQI feedback coding, data pass through UE-
specific search space（The specific search space of user equipment）Scrambling after, carry out QPSK（Quadrature
Phase Shift Keying, QPSK）Modulation；
Format2A：ACK/NACK information for sending 20 bits plus 1 bit after up CQI feedback coding, is carried out
BPSK（Binary Phase Shift Keying, binary phase shift keying）Modulation；
Format2B：ACK/NACK information for sending 20 bits plus 2 bits after up CQI feedback coding, is used
QPSK is modulated；
PUCCH resource maps：PUCCH is located at the both sides of system bandwidth, and two time slots of a subframe take frequency-hopping mode
Obtain frequency diversity gain.
LTE-A agreements are because newly-increased carrier aggregation function introduces PUCCH1B CS forms（PUCCH Format1B
with Channel Selection）, for transmitting to descending ACK/NACK feedbacks.It can be fed back by using form UE
The downlink reception result of different carrier waves.
PUCCH1B CS are that the PUCCH1B forms based on LTE R8/9 agreements are derived, although or only carry
2BIT feedback information, but base station passes through the content for detecting PUCCH1BCS resource location and carrying, root in each subframe
According to the mapping form provided in agreement, that is, it can confirm that downlink reception results of the UE in each carrier wave.PUCCH1B CS forms are most
Support lower 2 code words of 2 carrier waves in the reception condition of multiple descending sub frames, during terminal feedback reception result, workable resource
Position has two kinds：A kind of is the CCE indexes used by PDCCH, and the formula provided using agreement, which is calculated, to be obtained；Another is logical
High-rise signal deployment is crossed to obtain.The resource location in two kinds of sources, UE selects corresponding resource-niche according to reception condition according to agreement
Put and fed back.Present problems faced is that high-level signaling is that UE at most can configure four PUCCH1B CS resource locations, base station
Flexibly in four resource locations one of them can be specified to be used to UE by the field carried in PDCCH, this four resource-niches
Put how the ununified standard of distributorship agreement.
In the prior art, it is PUCCH1B in order to ensure that the PUCCH1B CS resource locations used between different UE will not conflict
CS individually divides one section of fixed resource and used, and the other PUCCH formats of this section of resource can not be used.This PUCCH1B CS resources
The method of salary distribution wastes very much Physical Uplink Control Channel PUCCH resource, there is direct influence on up handling capacity, and

Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is further detailed explanation.
For LTE-A, agreement 36.213R10 gives PUCCH1B CS application scenarios, is summarized as follows：
When UE is configured to 2 cells of carrier aggregation, ACK/NACK can be carried out to downlink business using PUCCH1B CS
Feedback, feedback takes PUCCH resourceIn FDD（Frequency Division Duplexing, FDD）With
TDD（Time Division Duplexing, time division duplex）Under pattern, UE is calculated, selectionMode, protocol processes
Flow is different, will illustrate respectively below：
Under FDD, protocol conventions PUCCH1B CS handling process：
UE selects a PUCCH resource position in A PUCCH resource positionFed back, wherein 0≤j≤
A-1。
Subframe n-4 in main plot receives PDCCH, the PUCCH resource position used
Wherein, nCCEThe first CCE numberings taken for this PDCCH,By high level configuration；When UE TM patterns（Transmission
Mode, transmission mode）Support 2 TB（Transmit Block, transmission block）When,
Subframe n-4 in main plot receives the PDSCH that no PDCCH is indicated（Physical Downlink Shared
Channel, physical down link sharing channel）,By high level configuration, when UE TM patterns support 2 TB,
PDCCH is received in the subframe n-4 of secondary cell, indicates that UE is used by 4 of high level configuration with the field in PDCCH
One or a pair in PUCCH resource, when UE TM patterns support 2 TB, field is indicated using a pair of PUCCH resources：Otherwise using a PUCCH resource
Under TDD, the calculating of PUCCH resource position, selection mode are different and different because downstream feedback set M sizes, and M is
Set K element number, what set K was represented is the descending sub frame set fed back in same sub-frame of uplink under TDD.
Under TDD, M=1 or when 2, protocol conventions PUCCH1B CS handling process：
As M=1 or M=2, if in main plot subframe n-kmReceive PDCCH, wherein km∈ K, K are directed to main plot, kmIt is
UE detected in set K in a value minimum in PDCCH subframe, i.e. feedback set K from feedback sub-frame of uplink point most
The near descending sub frame once dispatched.Define nCCE,mThe first CCE numberings taken for this PDCCH.Now, PUCCH resourceWherein, c ∈ { 0,1,2,3 }, and need to meet bar
Part For the number of PRB on downlink bandwidth
Amount,Frequency amount is uploaded for a PRB frequency domain.And when M=1 and UE TM patterns support 2 TB, PUCCH resource
If subframe n-k receives the PDSCH that no PDCCH is indicated in main plot,By high level configuration.
If receiving PDCCH, wherein k ∈ K in secondary cell subframe n-k, set K is directed to secondary cell, referred to the field in PDCCH
Show that, when M=1 and UE TM patterns support 2 TB, field is indicated using by one in 4 PUCCH resources of high level configuration
Use a pair of PUCCH resourcesOtherwise using a PUCCH resource
Under TDD, M>When 2, protocol conventions PUCCH1B CS handling process：
Work as M>When 2, there are 4 PUCCH resource positions：0≤i≤3.Wherein,WithWith main plot
PDSCH transmission or PDCCH release（PDCCH discharges）It is related；WithWith the PDSCH transmission phase of secondary cell
Close.
For main plot, if receiving the PDSCH that no PDCCH is indicated in subframe n-k,By high level configuration, for subframe n-
kmReceive PDSCH transmission or PDCCH release, wherein km∈ K, and the DAI in PDCCH（Downlink Assignment Index,
Downlink distribution index）It is worth for 1, PUCCH resource position
Otherwise, for subframe n-kmReceive PDSCH transmission or PDCCH release, wherein km∈ K, and DAI values in PDCCH are 1
Or 2, PUCCH resourceIt is 1 that i=0, which corresponds to DAI values,
PDCCH, i=1 correspond to DAI values for 2 PDCCH.
For secondary cell, if in subframe n-kmReceive by the cross-carrier scheduling PDSCH, wherein k of the PDCCH instructions of main plotm∈ K,
And the DAI values in PDCCH are 1 or 2, then PUCCH resource position
I=2 correspond to the PDCCH that DAI values are 1, and i=3 correspond to the PDCCH that DAI values are 2.If being received in subframe n-k by secondary cell
Non- cross-carrier scheduling PDSCH, wherein k ∈ K that PDCCH is indicated, then PUCCH resource positionWithPass through PDCCH
In field indicate that field indicates correspondence a pair of PUCCH money using by one in 4 PUCCH resource positions of high level configuration
Source：
Under summary FDD and TDD, a total of following 8 kinds of PUCCH resource position calculation formula.With bandwidth 100PRB,
DSUUD sub-frame formats（D is descending sub frame, and S is special subframe, and U is sub-frame of uplink）Exemplified by, calculate PUCCH resource span
As shown in table 1, wherein,The PUCCH resource position fed back for subframe n,Son during for 2 RB of transmission
Another PUCCH resource position, n that frame n is fed backCCEWith nCCE,mThe first CCE numberings taken for this PDCCH resource position,By high level configuration, For the quantity of PRB on downlink bandwidth,Frequency amount is uploaded for a PRB frequency domain, in this instance, (M-m-1) × Nc+m×Nc+1+nCCE, mSpan be 0-
317。
Table 1
Therefore, the major parameter of PUCCH resource position value during influence 2 cells of carrier aggregation is：
Configured by high level by the n1PUCCH-AN in PUCCH configuration parameters, span is 0~2047.
nCCEWith nCCE,m, it is the first CCE numberings that corresponding PDCCH resource position takes, span is 0~87.
SPS is passed through by high level（Semi Persist Schedule, semi-continuous scheduling）In configuration parameter
N1PUCCH-AN-PersistentList is configured, and span is 0~2047, and 4 values are can configure to a UE.
OrN1PUCCH-AN-CS- in PUCCH configuration parameters is passed through by high level
R10 is configured, and span is 0~2047,4 pairs of parameters is can configure to a UE, each pair is containing 2 values.
Wherein, nCCEWith nCCE,mThe first CCE numberings taken for corresponding PDCCH, this parameter values by agreement except being limited
Outside the span of system, it is impossible to limited, system call otherwise will be influenceed.Therefore, as seen from Table 1, PUCCH resource value
Parameter of the scope dependent on high-rise configuration：n1PUCCH-AN、N1PUCCH-AN-PersistentList、N1PUCCH-AN-CS-
r10.And PUCCH resource position is except for HARQ-ACK（Hybrid Automatic Repeat Request-
Acknowledgement, hybrid automatic repeat-request-positive acknowledgment）Feedback is outer, in addition it is also necessary to which distributing to UE is used for SR and CQI
Report, SR takes PUCCH resource position and configured by the sr-PUCCH-ResourceIndex in high-rise configuration parameter, and span is
0~2047；CQI takes PUCCH resource position and configured by the cqi-PUCCH-ResourceIndex in high-rise configuration parameter, takes
It is 0~1185 to be worth scope.
Therefore, it is high-rise that PUCCH resource is planned before configuration resource, as shown in figure 1, in order to prevent required resource
Between collide, all kinds of demands are divided successively between 0~2047, the SR resources of configuration, CQI resources, SPS configuration moneys
It is separate between source, the secondary cell configuration class resource of resource 4, it is not covered with region.It is high-rise by the maximum in 4 class resources of configuration
PUCCH resource value is asserted configuration parameter n1PUCCH-AN, i.e.,Understand that the maximum of PUCCH resource is with reference to table 1Span is 0~2047, i.e., high-rise configurationValue establishes all PUCCH resources
The maximum occurrences of position, as long as so reducing as far as possibleValue size can reduce resource shared by PUCCH, you can have
Effect expands PUSCH available resources scope, so as to improve uplink throughput.
High level configurationValue the maximum occurrences of PUCCH resource are determined, its span is 0~2047,
PUCCH resource presses Format1, Format1A/1B and Format2/2A/2B forms are divided into PUCCH（1）The resource of type and
PUCCH（2）The resource of type, the bandwidth of 20M down channel is equal to 100 PRB（Physical Resource Block, thing
Manage resource block）, whenValue 2047,36 PUCCH can be at most carried according to each PRB of protocol configuration（1）Type
During resource, onlyPRB numbers can be taken and just reach 2047/36 ≈ 57.Therefore, PUCCH resource is taken less in order to try one's best
Position, it is necessary to makeValue it is as far as possible small, two kinds of technical schemes commonly used in the art are as follows：
Scheme one：High level is the unique available PUCCH of each UE configurations（1）Resource；
For the N1PUCCH-AN-PersistentList configurations in SPS configuration parameters, to a UE, configurable 4 take
Value.High level only configures 1 value to a UE, to reduce occupancy.
For N1PUCCH-AN-CS-r10 configurations, 4 pairs of parameters are can configure to a UE, each pair is containing 2 values.It is high-rise right
One UE only configures 1 pair of value, to reduce occupancy.
Scheme two：High level is every 4 UE configuration identicals 4/to PUCCH（1）Resource；
For the N1PUCCH-AN-PersistentList configurations in SPS configuration parameters, 4 configurable to 4 UE identical
Value.4 PUCCH are shared between i.e. 4 UE（1）Resource, one and its are selected by PDCCH field in 4 positions
Resource location that its 3 UE does not conflict is used, and this method is also effectively reduced occupancy.
For N1PUCCH-AN-CS-r10 configurations, 4 UE can configure with 4 pairs of parameters, each pair is containing 2 values.I.e. high level is matched somebody with somebody
Put shared 4 couples of PUCCH between 4 UE（1）Resource, is also that a pair and other 3 are selected in 4 pairs of positions by PDCCH field
The resource that individual UE does not conflict is to use to reduce occupancy.
By above two scheme, in scheme one or scheme twoBy SR resources, CQI resources, SPS configurations
Resource, secondary cell configuration resource 4 class resource are determined, are all reduced to a certain extentConfiguration Values, but with being
What system was planned supports number of users to increase, and reserved number of resources increases therewith,Value is also increased.Such as planning system
System can support 400 survival users, be each 3 different resource values of user configuring according to scheme one（Containing N1PUCCH-AN-
PersistentList is configured to be configured with N1PUCCH-AN-CS-r10）, then 3 × 400=1200 resource locations are needed.According to side
Case two, every 4 users need 3 × 4=12 different resource values of configuration（Containing N1PUCCH-AN-PersistentList configuration with
N1PUCCH-AN-CS-r10 is configured）, then 12 × (400/4)=1200 resource location is needed.It can be seen that the two schemes point
As the result matched somebody with somebody is with effect.
Therefore, there is the defect of three aspects in above two scheme.First, two schemes are all equivalent to and uniquely configured for UE
One available SPS configurations and N1PUCCH-AN-CS-r10 configurations, accordingly even when the UE this there is no scheduling, this
PUCCH resource position, which remains on to reserve, to be come, and causes unnecessary waste；Second, high-rise configurationValue it is larger, can
Up more PRB can be taken to feed back, cause up PUSCH resource locations to reduce and influence system uplink handling capacity；Its
Three, scheme one does not utilize the function of PDCCH field flexible dispatchings, though scheme two make use of the work(of PDCCH field flexible dispatchings
Can, but actual effect is not introduced into obvious benefit as scheme one, also.
Reference picture 1, shows and plans schematic diagram according to a kind of PUCCH resource position of prior art, as shown in figure 1, will
Upstream bandwidth is divided into sequence number according to PRB unitsPRB quantity on expression upstream bandwidth, SR resources,
CQI resources, SPS configurations resource, secondary cell configuration resource determine the PUCCH resource position of high-rise configuration, in tdd mode subframe
When structure is DSUUD, 36 PUCCH can at most be carried by configuring each PRB（1）The resource location of type, is SR resources, SPS
Configure resource, secondary cell configuration resource respectively 2 PRB of distribution, thenThat is PUCCH（1）Type
Resource location at most need to take 216+318=534 index, need 534 ÷, 36 ≈ 15 PRB to deposit PUCCH（1）, and only
2 × 36=72 carrier aggregation user accesses can be carried.
Exactly inventor herein has found the seriousness of this problem, creatively proposes the core structure of the embodiment of the present invention
One of think of is, proposes the method and system that PUCCH resource position is distributed in a kind of lte-a system, can distribute 4 pairs of indexes
Shared to 8 UE, the distribution of downlink resource is realized using judging whether PUCCH resource position conflicts, therefore by high level configuration
'sBecome to be determined by SR resources, CQI resources, the SPS configurations class resource of resource 3, directly reduceMaximum take
Value, also just reduces the occupancy of PUCCH resource position, and then reduces the occupancy to PUSCH resource locations, so as to carry
More carrier aggregation user accesses, make full use of Physical Uplink Control Channel PUCCH resource, flexibly selection PUCCH1B CS
The channel of use, increases up handling capacity.
Reference picture 2, shows that PUCCH resource position is distributed in a kind of lte-a system according to an embodiment of the invention
Embodiment of the method 1 step flow chart, the lte-a system includes main plot and secondary cell, can specifically include following
Step：
Step 101, user equipment (UE) is handled successively from the Subscriber Queue for waiting descending scheduling；
In actual applications, user equipment (UE) sends descending scheduling request into Subscriber Queue, is arranged according to certain order
Descending scheduling is waited, user equipment (UE) is handled successively from Subscriber Queue.
Step 102, if currently processed UE is carrier aggregation user and has downlink business in the secondary cell, in high level
Available resource location is searched in the PUCCH resource position of configuration；
User of the carrier aggregation user for the two or more carrier units of polymerization to be transmitted.In lte-a system, UE enters
Entering can be simultaneously by multiple carrier units after connected state（CC1, CC2）Communicated with source base station, base station can pass through display
Configuration is that UE specifies a principal component carrier wave according to protocol conventions（Primary Component Carrier, PCC）, its
His carrier units are referred to as auxiliary component carrier（Secondary Component Carrier, SCC）, in principal component carrier wave
Serving cell is referred to as main plot（Primary Cell, Pcell）, the serving cell in auxiliary component carrier is referred to as secondary cell
（Secondary Cell, Scell）.High level refers to LTE RRC protocol layers, and RRC protocol layers are disappeared by signaling as defined in agreement
Breath, by PUCCH resource position by signal deployment to UE, while being allocated to base station, base station and UE use same PUCCH resource
It can be communicated during position.In the specific implementation, the PUCCH resource position of the high-rise configuration is being used for for high-rise configuration
Hybrid automatic repeat-request-positive acknowledgment HARQ-ACK PUCCH resource interval range is fed back, being used for for the high-rise configuration is anti-
Present hybrid automatic repeat-request-positive acknowledgment HARQ-ACK PUCCH resource interval range can with by control channel unit CCE
The PUCCH resource interval range of calculating is overlapped, that is, passes through the PUCCH resource position that will be calculated by CCE and the PUCCH of high-rise configuration
Resource location overlaps reserved mode, and the PUCCH resource position calculated by CCE is distributed into terminal by high level and used
Taken during PUCCH1BCS.It is further preferred that the high-rise configuration be used for feed back hybrid automatic repeat-request-positive acknowledgment
The original position of HARQ-ACK PUCCH resource interval range can indicate CQI by dispatch request SR resources, down channel quality
Resource, semi-continuous scheduling SPS configuration resources are determined.
When UE is carrier aggregation user and when having downlink business in the secondary cell, distributes to 8 UE due to 4 pairs of indexes and be total to
With, then need high level configuration PUCCH resource position in search available resource location.
In actual applications, LTE downlink transfer pattern mainly includes following several：
