Description

The method and system that in LTE-A system, PUCCH resource location distributes

Technical field

The present invention relates to communication technical field, particularly relate to a kind of method that in LTE-A system, PUCCH resource location distributes, and, the system that in a kind of LTE-A system, PUCCH resource location distributes.

Background technology

At LTE(Long Term Evolution, long evolving system) in system, LTE-A(LTE-Advanced, advanced long evolving system) be the evolution version of LTE, in order to meet the descending peak of LTE-A speed 1Gbps, the requirement of up peak speed 500Mbps, the transmission bandwidth of maximum 100MHz need to be provided, but rare due to the continuous frequency spectrum of so large bandwidth, LTE-A has proposed the solution of carrier aggregation (Carrier Aggregation, CA).So-called carrier aggregation is 2 or more carrier wave unit (Component Carrier, CC) to be condensed together to support to be to the maximum the transmission bandwidth of 100MHz.

PUCCH(Physical Uplink Control CHannel, physical uplink control channel) mainly carry SR(Schedule Request, dispatch request), ACK/NACK(Acknowledgement, positive acknowledgement/Negative Acknowledgement, Negative Acknowledgement) and CQI/PMI(Channel Quality Indicator, down channel quality indication/Precoding Matrix Indicator, pre-coding matrix indication), RI(Rank Indicator, stratum's indication), Format1 corresponding to PUCCH, Format1A/1B and Format2/2A/2B form.

Format1: for UE(User Equipment, subscriber equipment) up transmission dispatch request, base station side only needs to detect whether have such transmission;

Format1A/1B: for the up transmission of UE ACK/NACK;

Format1 is at system L3(layer 3) signal deployment is to the transmitted over resources of 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 to transmit simultaneously, the transmitted over resources uplink ACK/NACK at L3 signal deployment to SR.The resource that the upper transmission of PUCCH uplink ACK takies is by RB(Resource Block, Resource Block) ID, frequency domain CDM code(frequency domain code) and field code during time domain CDM code() definite.

Format2: for sending the ACK/NACK information of 20 bits after up CQI feedback encoding, the data process specific search volume of UE-specific search space(subscriber equipment) after scrambling, carry out QPSK(Quadrature Phase Shift Keying, Quadrature Phase Shift Keying) modulation;

Format2A: add the ACK/NACK information of 1 bit for sending 20 bits after up CQI feedback encoding, carry out BPSK(Binary Phase Shift Keying, binary phase shift keying) modulation;

Format2B: add the ACK/NACK information of 2 bits for sending 20 bits after up CQI feedback encoding, adopt QPSK modulation;

PUCCH resource mapping: PUCCH is positioned at the both sides of system bandwidth, and two time slots of a subframe take frequency-hopping mode to obtain frequency diversity gain.

LTE-A agreement is because newly-increased carrier aggregation function has been introduced PUCCH1B CS form (PUCCH Format1B with Channel Selection), for transmitting descending ACK/NACK feedback.By using this form UE can feed back the descending reception result of different carrier.

PUCCH1B CS is that the PUCCH1B form based on LTE R8/9 agreement is derivative and next, although still only carry the feedback information of 2BIT, but base station in each subframe by the resource location of PUCCH1BCS and the content of carrying being detected, according to the mapping form providing in agreement, can confirm that UE is at the descending reception result of each carrier wave.PUCCH1B CS form supports at most 2 lower 2 code words of carrier wave in the reception condition of a plurality of descending sub frames, during terminal feedback reception result, spendable resource-niche is equipped with two kinds: a kind of is the CCE index using by PDCCH, uses the formula that agreement provides to calculate acquisition; Another kind is to configure acquisition by high-level signaling.The resource location in two kinds of sources, UE, according to reception condition, selects corresponding resource location to feed back according to agreement.The problem facing is now, high-level signaling is UE configurable four PUCCH1B CS resource locations at most, base station can specify one of them to UE, to use by the field of carrying in PDCCH flexibly in four resource locations, and how distributorship agreement does not have unified standard to these four resource locations.

In prior art, for the PUCCH1B CS resource location that guarantees to use between different UEs can not conflict, for PUCCH1B CS divides separately one section of fixing resource, use, this section of other PUCCH form of resource can not be used.The resource that this PUCCH1B CS resource distribution mode is wasted very much Physical Uplink Control Channel PUCCH, has direct impact to up throughput, and the channel that PUCCH1B CS adopts can not be selected flexibly by the field of PDCCH.

Therefore, need at present the urgent technical problem solving of those skilled in the art to be exactly: the mechanism that in a kind of LTE-A system, PUCCH resource location distributes is provided, in order to make full use of the resource of Physical Uplink Control Channel PUCCH, increase up throughput, and the channel that can select flexibly PUCCH1B CS to adopt.

Embodiment

For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

For LTE-A, agreement 36.213R10 has provided the application scenarios of PUCCH1B CS, is summarized as follows:

When UE is configured to 2 communities of carrier aggregation, can adopt PUCCH1B CS to carry out ACK/NACK feedback to downlink business, feedback takies PUCCH resource

in FDD(Frequency Division Duplexing, Frequency Division Duplexing (FDD)) with TDD(Time Division Duplexing, time division duplex) under pattern, UE calculates, selects

mode, protocol processes flow process different, below will describe respectively:

Under FDD, the handling process of agreement agreement PUCCH1B CS:

UE selects a PUCCH resource location in A PUCCH resource location

feed back, wherein 0≤j≤A-1.

Subframe n-4 in main plot receives PDCCH, the PUCCH resource location of use

wherein, n _cCEthe first CCE numbering that PDCCH takies for this reason,

by high level, configured; When the TM of UE pattern (Transmission Mode, transmission mode) is supported 2 TB(Transmit Block, transmission block) time,

Subframe n-4 in main plot receives the PDSCH(Physical Downlink Shared Channel without PDCCH indication, physical down link sharing channel),

by high level, configured, when the TM of UE pattern is supported 2 TB,

The subframe n-4 of Fu community receives PDCCH, with the field indication UE in PDCCH, uses in 4 PUCCH resources that configured by high level one or a pair of, and when the TM of UE pattern is supported 2 TB, a pair of PUCCH resource is used in field indication:

otherwise use a PUCCH resource

Under TDD, the calculating of PUCCH resource location, selection mode because of the difference of downstream feedback set M size different, M is the element number of set K, set K representative be the descending sub frame set of feeding back at same sub-frame of uplink under TDD.

Under TDD, M=1 or 2 o'clock, the handling process of agreement agreement PUCCH1B CS:

When M=1 or M=2, if at main plot subframe n-k _mreceive PDCCH, wherein k _m∈ K, K is for main plot, k _ma minimum value in the subframe of to be UE detect in set K PDCCH, i.e. put the descending sub frame of recent scheduling from the sub-frame of uplink of feedback in feedback set K.Definition n _{cCE, m}the first CCE numbering that PDCCH takies for this reason.Now, PUCCH resource $n_{\mathrm{PUCCH},j}^{\left(1\right)}=(M-m-1)\×N_c+m\×N_{c+1}+n_{\mathrm{CCE},m}+N_{\mathrm{PUCCH}}^{\left(1\right)}.$ Wherein, c ∈ 0,1,2,3}, and need eligible

for the quantity of PRB on downlink bandwidth,

be that a PRB frequency domain is uploaded frequency amount.And when the TM of M=1 and UE pattern is supported 2 TB, PUCCH resource $n_{\mathrm{PUCCH},j+1}^{\left(1\right)}=(M-m-1)\×N_c+m\×N_{c+1}+n_{\mathrm{CCE},m}+N_{\mathrm{PUCCH}}^{\left(1\right)}.$

If receive the PDSCH without PDCCH indication at main plot subframe n-k,

by high level, configured.

Ruo Fu community subframe n-k receives PDCCH, wherein k ∈ K, gathers K for auxiliary community, with the field indication in PDCCH, uses in 4 PUCCH resources that configured by high level, when the TM of M=1 and UE pattern is supported 2 TB, a pair of PUCCH resource is used in field indication otherwise use a PUCCH resource

Under TDD, during M>2, the handling process of agreement agreement PUCCH1B CS:

When M>2, there are 4 PUCCH resource locations: 0≤i≤3.Wherein,

with

discharge to PDSCH transmission or the PDCCH release(PDCCH of main plot) relevant;

with the PDSCH transmission of Yu Fu community is relevant.

For main plot, if receive the PDSCH without PDCCH indication at subframe n-k,

by high level, configured, for subframe n-k _mreceive PDSCH transmission or PDCCH release, wherein k _m∈ K, and the DAI(Downlink Assignment Index in PDCCH, downlink allocation index) value is 1, PUCCH resource location $n_{\mathrm{PUCCH},1}^{\left(1\right)}=(M-m-1)\×N_c+m\×N_{c+1}+n_{\mathrm{CCE},m}+N_{\mathrm{PUCCH}}^{\left(1\right)};$ Otherwise, for subframe n-k _mreceive PDSCH transmission or PDCCH release, wherein k _m∈ K, and the DAI value in PDCCH is 1 or 2, PUCCH resource $n_{\mathrm{PUCCH},i}^{\left(1\right)}=(M-m-1)\×N_c+m\×N_{c+1}+n_{\mathrm{CCE},m}+N_{\mathrm{PUCCH}}^{\left(1\right)},$ The PDCCH that i=0 is 1 corresponding to DAI value, the PDCCH that i=1 is 2 corresponding to DAI value.

For auxiliary community, if at subframe n-k _mreceive by the PDCCH indication of main plot across carrier dispatching PDSCH, wherein k _m∈ K, and the DAI value in PDCCH is 1 or 2, PUCCH resource location $n_{\mathrm{PUCCH},i}^{\left(1\right)}=(M-m-1)\×N_c+m\×N_{c+1}+n_{\mathrm{CCE},m}+N_{\mathrm{PUCCH}}^{\left(1\right)},$ The PDCCH that i=2 is 1 corresponding to DAI value, the PDCCH that i=3 is 2 corresponding to DAI value.If it is non-across carrier dispatching PDSCH to receive that at subframe n-k the PDCCH of You Fu community indicates, wherein k ∈ K, PUCCH resource location

with

by the field indication in PDCCH, use in 4 PUCCH resource locations that configured by high level, the corresponding a pair of PUCCH resource of field indication:

Under comprehensive above-mentioned FDD and TDD, PUCCH resource location computing formula has following 8 kinds altogether.With bandwidth 100PRB, DSUUD sub-frame formats (D is descending sub frame, and S is special subframe, and U is sub-frame of uplink) is example, calculates PUCCH Scope of Resources as shown in table 1, wherein, the PUCCH resource location feeding back for subframe n,

another PUCCH resource location that subframe n when transmitting 2 RB feeds back, n _cCEwith n _{cCE, m}the first CCE numbering that PDCCH resource location takies for this reason,

by high level, configured,

for the quantity of PRB on downlink bandwidth,

be that a PRB frequency domain is uploaded frequency amount, in this example, (M-m-1) * N _c+ m * N _c+1+ n _{cCE, m}span be 0-317.

Table 1

The major parameter of the PUCCH resource location value while therefore, affecting 2 communities of carrier aggregation is:

by high level, by the n1PUCCH-AN in PUCCH configuration parameter, configured, span is 0～2047.

N _cCEwith n _{cCE, m}, be the first CCE numbering that corresponding PDCCH resource location takies, span is 0～87.

by high level by SPS(Semi Persist Schedule, semi-continuous scheduling) N1PUCCH-AN-PersistentList configuration in configuration parameter, span is 0～2047, to configurable 4 values of UE.

or

by high level, by the N1PUCCH-AN-CS-r10 in PUCCH configuration parameter, configured, span is 0～2047, and to the configurable 4 pairs of parameters of UE, every pair containing 2 values.

Wherein, n _cCEwith n _{cCE, m}for the first CCE numbering that corresponding PDCCH takies, this parameter values, except the span by protocols limit, can not limit, otherwise will affect system call.Therefore, as seen from Table 1, the scope of PUCCH resource value depends on the parameter of high-rise configuration: n1PUCCH-AN, N1PUCCH-AN-PersistentList, N1PUCCH-AN-CS-r10.And PUCCH resource location is except for HARQ-ACK(Hybrid Automatic Repeat Request-Acknowledgement, mixed automatic retransfer request-positive acknowledgement) outside feedback, also needing to distribute to UE reports for SR and CQI, SR takies the sr-PUCCH-ResourceIndex of PUCCH resource location in high-rise configuration parameter and configures, and span is 0～2047; CQI takies the cqi-PUCCH-ResourceIndex of PUCCH resource location in high-rise configuration parameter and configures, and span is 0～1185.

Therefore, high level is planned PUCCH resource before resource allocation, as shown in Figure 1, in order to prevent bumping between resource requirement, from 0～2047, all kinds of demands are divided successively, separate between the SR resource of configuration, CQI resource, SPS resource allocation, auxiliary cell configuration resource 4 class resources, there is no overlay area.High level is asserted configuration parameter n1PUCCH-AN by the maximum PUCCH resource value in 4 class resources of configuration, associative list 1 is known, and the maximum of PUCCH resource is

span is 0～2047, i.e. high-rise configuration

value has been established the maximum occurrences of all PUCCH resource locations, so as long as reduce as far as possible

value size can reduce the shared resource of PUCCH, can effectively expand the available resources scope of PUSCH, thereby improve uplink throughput.

High-rise configuration

value determined the maximum occurrences of PUCCH resource, its span is 0～2047, PUCCH resource is pressed Format1, Format1A/1B and Format2/2A/2B form, be divided into PUCCH(1) resource and the PUCCH(2 of type) resource of type, the bandwidth of the down channel of 20M equals 100 PRB(Physical Resource Block, Physical Resource Block), when

value 2047, can carry at most 36 PUCCH(1 according to each PRB of protocol configuration) during the resource of type, only can take PRB number and just reach 57 of 2047/36 ≈.Therefore,, in order to take less PUCCH resource location as far as possible, just need to make

value as far as possible little, the conventional two kinds of technical schemes in this area are as follows:

Scheme one: high-rise is the unique available PUCCH(1 of each UE configuration) resource;

For the N1PUCCH-AN-PersistentList configuration in SPS configuration parameter, to configurable 4 values of UE.High level only configures 1 value to a UE, to reduce occupancy.

For N1PUCCH-AN-CS-r10 configuration, to the configurable 4 pairs of parameters of UE, every pair containing 2 values.High level only configures 1 pair of value to a UE, to reduce occupancy.

Scheme two: high-rise for every 4 UE configure identical 4/to PUCCH(1) resource;

For the N1PUCCH-AN-PersistentList configuration in SPS configuration parameter, to 4 configurable 4 identical values of UE.Between 4 UE, share 4 PUCCH(1) resource, by the field of PDCCH, in 4 positions, select a resource location not conflicting with other 3 UE to use, this method also can effectively reduce occupancy.

For N1PUCCH-AN-CS-r10 configuration, to 4 configurable 4 pairs of parameters of UE, every pair containing 2 values.Between 4 UE of high-rise configuration, share 4 couples of PUCCH(1) resource is also in 4 pairs of positions, to select resource a pair of and that other 3 UE do not conflict to use to reduce occupancy by the field of PDCCH.

Known by above-mentioned two schemes, in scheme one or scheme two

by SR resource, CQI resource, SPS resource allocation, auxiliary cell configuration resource 4 class resources, determined, all reduced to a certain extent

configuration Values, but along with the number of users supported of systems organization increases, reserved number of resources increases thereupon,

value also increases thereupon.For example planning system can be supported 400 survival users, according to scheme one, for each user configures 3 different resource values (containing N1PUCCH-AN-PersistentList configuration and N1PUCCH-AN-CS-r10 configuration), need 3 * 400=1200 resource location.According to scheme two, every 4 users need to configure 3 * 4=12 different resource value (containing N1PUCCH-AN-PersistentList configuration and N1PUCCH-AN-CS-r10 configuration), need 12 * (400/4)=1200 resource location.Can find out that the result that these two schemes are distributed is the same with effect.

Therefore there is the defect of three aspects in above-mentioned two schemes.One, two schemes are all equivalent to and for UE is unique, have configured an available SPS configuration and N1PUCCH-AN-CS-r10 configuration, even like this this UE this do not obtain scheduling, this PUCCH resource location is also still reserved out, causes unnecessary waste; Its two, high-rise configuration

value larger, may take up more PRB in order to feedback, cause up PUSCH resource location to reduce and affect system uplink throughput; Its three, scheme one is not utilized the function of PDCCH field flexible dispatching, though scheme two has been utilized the function of PDCCH field flexible dispatching, but actual effect is the same with scheme one, does not also introduce obvious benefit.

With reference to Fig. 1, show a kind of PUCCH resource location planning schematic diagram according to prior art, as shown in Figure 1, upstream bandwidth is divided into sequence number according to PRB unit

the quantity that represents PRB on upstream bandwidth, SR resource, CQI resource, SPS resource allocation, auxiliary cell configuration resource are determined the PUCCH resource location of high-rise configuration, when under tdd mode, subframe structure is DSUUD, configure each PRB and can carry at most 36 PUCCH(1) resource location of type, for SR resource, SPS resource allocation, auxiliary cell configuration resource are respectively distributed 2 PRB, so

be PUCCH(1) resource location of type need to take at most 216+318=534 index, needs 15 PRB of 534 ÷ 36 ≈ to deposit PUCCH(1), and can only carry 2 * 36=72 carrier aggregation user and access.

Inventor herein finds the seriousness of this problem just, one of core idea that creatively proposes the embodiment of the present invention is, the method and system that in a kind of LTE-A system, PUCCH resource location distributes is proposed, can share 4 pairs of index assignment to 8 UE, utilize to judge whether PUCCH resource location conflicts to realize the distribution of downlink resource, therefore high level is configured

become by SR resource, CQI resource, SPS resource allocation 3 class resources and determine, directly reduced

maximum occurrences, also just reduced taking of PUCCH resource location, and then reduced taking PUSCH resource location, thereby can carry more carrier aggregation user's access, make full use of the resource of Physical Uplink Control Channel PUCCH, the channel of selecting PUCCH1B CS to adopt flexibly, increases up throughput.

With reference to Fig. 2, show the flow chart of steps of the embodiment of the method 1 that in a kind of according to an embodiment of the invention LTE-A system, PUCCH resource location distributes, described LTE-A system comprises He Fu community, main plot, specifically can comprise the following steps:

Step 101 is processed successively user equipment (UE) from the Subscriber Queue of wait descending scheduling;

In actual applications, user equipment (UE) sends descending scheduling request in Subscriber Queue, according to a definite sequence, arranges and waits for descending scheduling, processes successively user equipment (UE) from Subscriber Queue.

Step 102, is carrier aggregation user and has downlink business in described auxiliary community if work as the UE of pre-treatment, in the PUCCH resource location of high level configuration, searches available resource location;

Carrier aggregation user is the user of the two or more carrier waves of polymerization unit to transmit.In LTE-A system, UE can pass through a plurality of carrier waves unit (CC1 after entering connected state simultaneously, CC2) communicate with source base station, base station can or approximately be decided to be a principal component carrier wave (Primary Component Carrier of UE appointment according to agreement by the configuration of demonstration, PCC), other carrier wave unit is called auxiliary component carrier (Secondary Component Carrier, SCC), Serving cell on principal component carrier wave is called main plot (Primary Cell, Pcell), Serving cell on auxiliary component carrier is called auxiliary community (Secondary Cell, Scell).High level refers to the RRC protocol layer of LTE, the signaling message that RRC protocol layer is stipulated by agreement, by PUCCH resource location by signal deployment to UE, configure to base station simultaneously, when same PUCCH resource location is used with UE in base station, can communicate by letter mutually.In specific implementation, the PUCCH resource location of described high-rise configuration be high-rise configuration for feeding back the PUCCH resource interval range of mixed automatic retransfer request-positive acknowledgement HARQ-ACK, can overlapping with the PUCCH resource interval range being calculated by control channel unit CCE for feeding back the PUCCH resource interval range of mixed automatic retransfer request-positive acknowledgement HARQ-ACK of described high-rise configuration, by reserved mode that the PUCCH resource location of the PUCCH resource location being calculated by CCE and high-rise configuration is overlapped, the PUCCH resource location being calculated by CCE is distributed to when terminal is used PUCCH1BCS and taken by high level.More preferably, described high-rise configuration can be determined by dispatch request SR resource, down channel quality indication CQI resource, semi-continuous scheduling SPS resource allocation for feeding back the original position of the PUCCH resource interval range of mixed automatic retransfer request-positive acknowledgement HARQ-ACK.

When UE is carrier aggregation user and while having downlink business in described auxiliary community, due to 4 pairs of index assignment, give 8 UE and share, need in the PUCCH resource location of high level configuration, search available resource location.

In actual applications, the downlink transfer pattern of LTE mainly comprises following several:

1, TM1, single antenna port transmission: the occasion that is mainly used in single antenna transmissions;

2, TM2, sends diversity mode: be suitable for cell edge channel situation more complicated, disturb larger situation, sometimes, also for situation at a high speed, diversity can provide diversity gain;

3, TM3, large delay diversity: the situation that is appropriate to UE high-speed mobile;

4, TM4, Closed-Loop Spatial Multiplexing: be suitable for the good occasion of channel condition, for high data rate transmission is provided;

5, TM5, multi-user's multiple-input and multiple-output (MU-MIMO) transmission mode: the capacity that is mainly used to improve community.

6, TM6, the transmission of single current (Rank1): the situation that is mainly suitable for cell edge.

7, single current wave beam TM7, Port5(logic port 5) forms (Beamforming) pattern: be also mainly cell edge, and can be effectively to anti-interference.

8, TM8, double-current wave beam forms (Beamforming) pattern: can also can be applied to other scenes for cell edge.
