Description

A kind of definite method and device of PUCCH resource

Technical field

The present invention relates to the communications field, particularly a kind of definite method and device of PUCCH resource.

Background technology

In current standard, HARQ-ACK(Hybrid Automatic Repeat request-ACK, mixed automatic retransfer request-reply) can pass through several PUCCH Format(Physical Uplink Control Channel Format, physical uplink control channel form) transmission, for example, PUCCH Format1a/1b/3.Its content introduction transmitting is separately as follows:

1) use PUCCH format 1a to transmit the HARQ-ACK information of 1 bit, or, at FDD(Frequency division duplex, Frequency Division Duplexing (FDD)) in situation, use PUCCH format 1a transmission by the HARQ-ACK of 1 bit and positive SR(Scheduling Request, SR) joint transmission.

2) use PUCCH format 1b to transmit the HARQ-ACK of 2 bits or by the HARQ-ACK of 2 bits and positive SR joint transmission.

3) in FDD system, UE has been configured more than 1 Serving cell or TDD(Time division duplex, time division duplex; ) when UE is configured Liao Yige Serving cell in system, use PUCCH format1b to adopt channel selective mode to transmit maximum 4 bit HARQ-ACK.

4) use the HARQ-ACK of maximum 10 bits or the HARQ-ACK of maximum 20 bits in TDD system in PUCCH format 3 transmission FDD systems.

5) use PUCCH format 3 transmits HARQ-ACK and positive/negative SR of 1 bit of maximum 10 bits in FDD system simultaneously, or, the HARQ-ACK of maximum 20 bits in TDD system and positive/negative SR of 1 bit.

Under prior art, the PUCCH basic sequence adopting while adopting PUCCH format1a/1b/3 transmitting HARQ-ACK generates according to UE Serving cell ID, and at present, the PUCCH resource of carrying HARQ-ACK transmission has three kinds of configuration modes:

The first is: by high-rise RRC(Radio Resource Control, Radio Resource is controlled) signal deployment.Mainly for SPS(semi-persistent scheduling, accurate continuous dispatching) corresponding HARQ-ACK transmission.

The second is: by the corresponding CCE index(Control of the DCI Channel Element index of indication HARQ-ACK transmission, control channel unit index) carry out recessiveness and indicate.

Concrete, the PUCCH resource representation that UE is used on antenna port P=P0 is

wherein, n _cCEfor corresponding DCI(Downlink Control Information, Downlink Control Information) first CCE numbering (i.e. the minimum CCE numbering that the PDCCH signaling of the above-mentioned PUCCH resource of transmission indication is used) of using of transmission,

for the dynamically exclusive high-rise configuration in HARQ-ACK resource original position ，You community.When UE supports 2 antenna PUCCH transmission or two TB(Transport Block, transmission block) HARQ-ACK feedback time, the resource used of its second antenna or second code word be the resource of first antenna/code word employing $n_{\mathrm{pUCCH}}^{(1,p=p0)}+1.$

The third is: by the ARI(ACK resource indication in PDCCH, ACK resource indication) signaling dynamically indicates.

Table 1

(HARQ-ACK PUCCH Resource used value)

ARI territory in the DCI format of corresponding PDCCH in order to determine a PUCCH resource value in the pre-configured semi-static resource value of 4 high-level signalings, and its corresponding relation is as shown in table 1.When UE supports the HARQ-ACK feedback of 2 antenna PUCCH transmission or two TB, high-level signaling need to be respectively each antenna port/code word and configure corresponding PUCCH resource, otherwise, need to be only individual antenna port/code word resource allocation.In current standard, ARI is by reusing the TPC(Transmit Power Control of PUCCH, and through-put power is controlled) order indicates.

RRH(Remote Radio Head Remote Radio Unit), claim again RRU, RRE, spaced antenna etc., is one and BBU(Base Band Unit, baseband processing unit) separated radio frequency unit; Conventionally, RRH is placed on different geographical position from BBU.RRH comprises radio circuit, A/D, and D/A conversion, the parts such as light delivery module, RRH is connected with BBU by optical fiber.Distributed RRH is a kind of network form of utilizing RRH networking.It is inner that RRH is dispersed in Yi Ge community, because the distance apart from terminal is less, can provide high-quality communication service to terminal.Because the data of all RRH in Yi Ge community are all focused on by BBU, this just give efficient collaboration, both between RRH brought may, therefore distributed RRH becomes an important scene of CoMP research.Wherein typical YouRRHHe base station macrocell has same cells ID(specifically as shown in Figure 1), and RRHHe base station macrocell has different districts ID(specifically as shown in Figure 2) these two kinds of scenes.

In scene due to close together ， different districts ID between RRH, the PUCCH of the terminal that Liang Ge RRH community is served can disturb between transmitting conventionally, thereby affects the transmission performance of up PUCCH.In order to address this problem, at present, the exclusive dynamic HARQ-ACK resource original position of UE and the method for PUCCH serial ID have been proposed to introduce, in order to replace the exclusive resource original position in community, and replace community ID to generate PUCCH basic sequence, thereby the PUCCH that realizes different districts user's quadrature by scheduling transmits, reduce the interference between PUCCH between different districts.Its schematic diagram is as Fig. 3, and wherein dynamic HARQ-ACK region 2 is specifically designed to the PUCCH transmission of minizone quadrature, and the dynamic HARQ-ACK resource original position exclusive by UE realizes.Meanwhile, under prior art, support UE not use community ID to generate PUCCH sequence, but base station is for a PUCCH serial ID of each UE distribution, uses this PUCCH serial ID to generate PUCCH sequence.

According to prior art, the dynamic HARQ-ACK resource of UE is still relevant with the CCE numbering that corresponding DCI transmission is used.Even if there has been the exclusive dynamic HARQ-ACK resource original position of UE, because network side may be by the CCE transmission DCI of any numbering, therefore, corresponding dynamically HARQ-ACK region need to take a large amount of resources, and may take these resources in a plurality of communities simultaneously.So, if the terminal of carrying out PUCCH transmission in this dynamic HARQ-ACK region seldom, can make resource utilization reduce; In addition, because the PDCCH resource (carrying the CCE of DCI) of different districts is that independent allocation is to each terminal, thereby the terminal of different districts carrying out HARQ-ACK when transmission, the PUCCH resource of using probably bumps, thereby causes transmission performance to decline obviously.

Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.

Consult shown in Fig. 4, in the embodiment of the present invention, network side apparatus (Ru， base station) comprises communication unit 40 and processing unit 41, wherein,

Communication unit 40, for being defined as the PUCCH resource original position of UE distribution and notifying UE;

Processing unit 41, for the size based on above-mentioned PUCCH resource original position and dynamic PUCCH resource area, adopts with the frequency pattern of UE agreement and determines the PUCCH resource of distributing to UE.

Consult shown in Fig. 5, in the embodiment of the present invention, UE comprises communication unit 50 and control unit 51, wherein,

Communication unit 50, for determining the PUCCH resource original position of distributing according to base station notice;

Control unit 51, for the size based on above-mentioned PUCCH resource original position and dynamic PUCCH resource area, adopts the PUCCH resource of determining distribution with the frequency pattern of base station agreement.

Based on said system framework, to consult shown in Fig. 6, it is as follows that the detailed process of PUCCH resource distribution is carried out in embodiment of the present invention Zhong， base station:

Step 600: base station is defined as the PUCCH resource original position of UE distribution and notifies UE.

PUCCH resource original position can be determined according to the PUCCH scheduling of resource result in Huo Duo community, single community in embodiment of the present invention Zhong， base station.

Step 610: the size of base station based on above-mentioned PUCCH resource original position and dynamic PUCCH resource area, adopts with the frequency pattern of UE agreement and determine the PUCCH resource of distributing to UE.

The present embodiment Zhong， base station can be notified the size of dynamic PUCCH resource area in advance to UE, or, arrange the size in dynamic PUCCH region with UE, like this, UE can be after obtaining PUCCH resource original position, in conjunction with the size in dynamic PUCCH region, determine the particular location in dynamic PUCCH region.

On the other hand, in the embodiment of the present invention, the executive mode of step 610 is including but not limited to following two kinds:

A1, base station is after the original position of UE notice PUCCH resource, adopt with UE stipulated form and determine corresponding frequency pattern, and the size based on dynamic PUCCH resource area carries out delivery to definite frequency pattern, and determine according to delivery result and above-mentioned PUCCH resource original position the PUCCH resource of distributing to UE; Embodiment is identical with UE side, will in subsequent embodiment, introduce in detail.

In this case, base station only needs to determine PUCCH resource original position, without determining that again PUCCH transmits the CCE numbering of corresponding DCI, like this, different frequency patterns can be arranged with UE respectively in different districts, thereby the UE that guarantees different districts can distribute different PUCCH resources, and although UE in same community is used identical frequency pattern, but can be by the different PUCCH resource original position of base station assigns, thereby guarantee that the different UEs in same community can also be assigned to different PUCCH resources, effectively guaranteed the transmission performance of PUCCH, avoided the signal between each UE to disturb.

A2, determines base station in the process of PUCCH resource original position (before/simultaneously/afterwards), further determine that PUCCH transmits the numbering of first CCE of corresponding DCI use, adopt with UE stipulated form and determine corresponding frequency pattern, and the numbering of the size based on acquired dynamic PUCCH resource area, frequency pattern, first CCE, and PUCCH resource original position is determined the PUCCH resource of distributing to UE; Embodiment is identical with UE side, will in subsequent embodiment, introduce.

In this case, base station not only needs to determine PUCCH resource original position, also need to determine again that PUCCH transmits first CCE numbering of corresponding DCI, like this, can be in conjunction with frequency pattern, the PUCCH resource of further each UE being used is distinguished, and avoids the PUCCH transmission between each UE to produce phase mutual interference, has further guaranteed the transmission performance of PUCCH.

In the present embodiment, base station and UE frequency pattern is according to a preconcerted arrangement determined respectively the frequency hopping value on each subframe or time slot, and is needing transmitting HARQ-ACK or/and determine respectively and distribute to the PUCCH resource that UE is used based on corresponding frequency hopping value on the subframe of CQI or time slot.

Further, in order to make UE can access PUCCH resource more accurately, improve PUCCH resource utilization, definite, distribute to after the PUCCH resource of UE, base station can adopt PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) or E-PDCCH(strengthen Physical Downlink Control Channel) to UE, send the signaling that indicates whether to carry out the adjustment of PUCCH resource, for example, base station is being judged according to network resource scheduling situation while there is resource contention in above-mentioned PUCCH resource, can be according to adjusting strategy or with UE stipulated form, fixed PUCCH resource being made to further adjustment, and adopt PDCCH or E-PDCCH to send PUCCH resource adjustment signaling to UE, notice UE adjusts accordingly fixed PUCCH resource, certainly, while there is not resource contention on the PUCCH that judgement UE in ，Ruo base station is assigned on the other hand, also can to UE, send PUCCH resource by PDCCH or E-PDCCH and adjust instruction, UE is without fixed PUCCH resource is adjusted for notice, can directly use.

So far, base station is final definite distributing to after the PUCCH resource of UE, just can take subframe or time slot as unit, need transmitting HARQ-ACK or/and adopt respectively the HARQ-ACK of corresponding PUCCH resource reception UE feedback or/and CQI on each subframe of CQI or time slot.

Consult shown in Fig. 7, corresponding with above-described embodiment, in the embodiment of the present invention, UE confirms and uses the detailed process of PUCCH resource as follows:

Step 700:UE determines the original position of the PUCCH resource of distributing according to base station notice.Concrete, PUCCH resource original position is designated as

The PUCCH resource original position of step 710:UE based on obtaining and the size of dynamic PUCCH resource area, adopt the PUCCH resource of determining distribution with the frequency pattern of base station agreement.

Accordingly, UE can determine according to base station notice the size of above-mentioned dynamic PUCCH resource area, or, also can arrange the size in dynamic PUCCH region with base station, in following examples, for convenience of description, the size in dynamic PUCCH region is designated as to m.

On the other hand, in the embodiment of the present invention, the concrete executive mode of step 710 is including but not limited to following two kinds:

B1, first, UE adopts with base station stipulated form and determines corresponding frequency pattern.

In the present embodiment, it is unit that subframe or time slot are take in the generation of frequency pattern, UEYu base station frequency pattern is according to a preconcerted arrangement determined respectively the frequency hopping value on each subframe or time slot, and is needing transmitting HARQ-ACK or/and determine respectively based on corresponding frequency hopping value the PUCCH resource being assigned on the subframe of CQI or time slot.

Take any one subframe or time slot as example, and its corresponding frequency pattern can be expressed as n _{fh, PUCCH}(n _s), wherein, n _srepresent transmitting HARQ-ACK or/and corresponding all time slots or first the corresponding time slot of the subframe of CQI obtains based on pseudo random sequence c (i), and the initial value c of pseudo random sequence _intone or more configuration parameter by UE calculates, as, comprise one or more of following parameter: UE Serving cell ID, the RNTI(Radio Network Temporary Identifier of UE, radio network temporary identifier) value; The PUCCH sequence of UE generates the ID of the sequence of using, the dynamic PUCCH resource original position of UE.

Secondly, the size of UE based on dynamic PUCCH resource area carried out delivery to definite frequency pattern, and determines according to the PUCCH resource original position of delivery result and acquisition the PUCCH resource self being assigned to.

For example, suppose that dynamic resource original position is dynamically PUCCH resource area size is m, and frequency pattern is n _{fh, PUCCH}(n _s), the PUCCH resource that UE is assigned to can be expressed as:

$n_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}=N_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}+n_{\mathrm{fh},\mathrm{PUCCH}}\left(n_s\right)\mathrm{mod}m$

B2, first, UE adopts with base station stipulated form and determines corresponding frequency pattern.

In like manner, in the present embodiment, it is unit that frequency pattern definite be take subframe or time slot, UEYu base station frequency pattern is according to a preconcerted arrangement determined respectively the frequency hopping value on each subframe or time slot, and is needing transmitting HARQ-ACK or/and determine respectively based on corresponding frequency hopping value the PUCCH resource being assigned on the subframe of CQI or time slot.

Take any one subframe or time slot as example, and its corresponding frequency pattern can be expressed as n _{fh, PUCCH}(n _s), wherein, n _srepresent transmitting HARQ-ACK or/and corresponding all time slots or first the corresponding time slot of the subframe of CQI obtains based on pseudo random sequence c (i), and the initial value c of pseudo random sequence _intone or more configuration parameter by UE calculates, as, comprise one or more of following parameter: UE Serving cell ID, the RNTI(Radio Network Temporary Identifier of UE, radio network temporary identifier) value; The PUCCH sequence of UE generates the ID of the sequence of using, the dynamic PUCCH resource original position of UE.

Secondly, the numbering that UE further notifies acquisition PUCCH to transmit first CCE of corresponding DCI use according to base station (is designated as n _cCE), and the size based on dynamic PUCCH resource area carries out delivery to the numbering of definite frequency pattern and above-mentioned first CCE, and determine the PUCCH resource of distributing according to delivery result and PUCCH resource original position.

For example, suppose that dynamic resource original position is

dynamically PUCCH resource area size is m, and frequency pattern is n _{fh, PUCCH}(n _s), first CCE that PUCCH transmits corresponding DCI use is numbered n _cCE, the PUCCH resource that UE is assigned to can be expressed as:

$n_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}=N_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}+(n_{\mathrm{fh},\mathrm{PUCCH}}\left(n_s\right)+n_{\mathrm{CCE}})\mathrm{mod}m$

On the other hand, in actual applications, also can be only to frequency pattern

carry out modulo operation, and not to first CCE numbering n _cCEdelivery, such scheme only be take both is all carried out to modulo operation as example.

Further, in the embodiment of the present invention, UE is in determining the process of PUCCH resource, if receive the PUCCH resource adjustment signaling that base station sends, according to this PUCCH resource, adjust instruction and determine whether to adjust fixed PUCCH resource, if desired adjust, according to the resource adjusted value of base station indication, fixed PUCCH resource is adjusted, or, according to the resource adjusted value of making an appointment with base station, fixed PUCCH resource is adjusted.

So far, UE determines after the PUCCH resource of base station assigns final, just can take subframe or time slot as unit, is needing transmitting HARQ ACK or/and adopt corresponding PUCCH resource to base station feedback HARQ-ACK or/and CQI on each subframe of CQI or time slot.

Preferably, the PDSCH(PDSCH Physical Downlink Shared Channel Physical Downlink Shared Channel that the method that the embodiment of the present invention provides can be dispatched for PDCCH) corresponding HARQ-ACK transmission is or/and CQI transmits, and HARQ-ACK that also can be corresponding for the PDSCH of E-PDCCH scheduling transmits or/and CQI transmission.

Two the concrete application scenarioss of take are below example, and above-described embodiment is made and being described in further detail.In following scene, suppose that PUCCH resource only carries HARQ-ACK transmission, thereby, PUCCH resource original position can be called to HARQ-ACK resource original position, dynamic PUCCH resource area is called to dynamic HARQ-ACK resource area.

The first situation is:

Base station notifies dynamic HARQ-ACK resource original position to be to UE

by high-level signaling, notify the size of the dynamic HARQ-ACK resource area of UE is m simultaneously.UE receives the notice of base station, and based on

and m, according to the frequency pattern n with base station agreement _{fh, PUCCH}(n _s), dynamically in HARQ-ACK resource area, carrying out frequency hopping, acquisition is carried out HARQ-ACK and is transmitted PUCCH resource used.Wherein, frequency pattern is

for pseudo random sequence and its initial value

weiUE Serving cell ID, UE carries out the PUCCH resource that HARQ-ACK transmission used and can be obtained by following formula:

$n_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}=N_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}+(n_{\mathrm{fh},\mathrm{PUCCH}}\left(n_s\right)+n_{\mathrm{CCE}})\mathrm{mod}m$

Wherein, n _cCEfor HARQ-ACK transmits first CCE numbering that corresponding DCI is used.Now, UE just can carry out HARQ-ACK transmission in the target P UCCH resource obtaining; The second situation is:

Base station to the dynamic HARQ-ACK resource of notice UE original position is

by high-level signaling, notify the size of the dynamic HARQ-ACK resource area of UE is m simultaneously.

Base station based on

and m, according to the frequency pattern n with UE agreement _{fh, PUCCH}(n _s), dynamically in HARQ-ACK resource area, carrying out frequency hopping, obtain and carry out the PUCCH resource that HARQ-ACK transmission is used.

Carry out alternately base station and other base stations, or, according to the PUCCH scheduling situation of Nei Ge community, base station, determine PUCCH resource that UE uses whether with the PUCCH resource contention of other UE, base station can send PUCCH resource to UE by down control channel and adjust signaling, thereby for fixed PUCCH resource, makes further adjustment according to conflict situations indication UE.

UE receive that base station sends about

with the notice of m, and based on

and m, according to the frequency pattern n with base station agreement _{fh, PUCCH}(n _s), dynamically in HARQ-ACK resource area, carrying out frequency hopping, obtain and carry out the PUCCH resource that HARQ-ACK transmission is used.Wherein, frequency pattern is

c (i) is pseudo random sequence and its initial value

weiUE Serving cell ID, n _rNTIfor the RNTI value of UE in belonging network.UE carries out the PUCCH resource that HARQ-ACK transmission used and can be obtained by following formula:

$n_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}=N_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}+n_{\mathrm{fh},\mathrm{PUCCH}}\left(n_s\right)\mathrm{mod}m$

UE receives the PUCCH resource adjustment signaling that base station sends, if signaling indication does not need to carry out resource adjustment, UE transmits PUCCH resource used using fixed PUCCH resource as finally carrying out HARQ-ACK; If signaling indication need to be carried out resource adjustment, UE adjusts the PUCCH resource obtaining in such a way:

$n_{\mathrm{PUCCH},\mathrm{UE}}^{(1,\exp )}=n_{\mathrm{PUCCH},\mathrm{UE}}^{\left(1\right)}+1;$

Now, UE just can carry out HARQ-ACK transmission in the final PUCCH resource obtaining.

In sum, in the embodiment of the present invention, UE is according to the PUCCH resource original position of base station notice, and the size of dynamic PUCCH resource area, adopt the frequency pattern of arranging with base station, dynamically in PUCCH resource area, by frequency-hopping mode, determining the PUCCH resource of distributing.Like this, effectively reduced the size of dynamic PUCCH resource area, reduced resource overhead, reduced the probability clashing between the PUCCH resource that different UEs used simultaneously, simultaneously, effectively improve again PUCCH resource utilization, and can support the PUCCH transmission of minizone quadrature, and then significantly improved PUCCH transmission performance.

Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
